Definitions

  • Hepatitis B is a liver disease that results from infection with the Hepatitis B virus (HBV). Its severity can be from a mild illness lasting a few weeks, to a serious, lifelong illness. Hepatitis B can be either acute or chronic. Acute Hepatitis B virus infection is a short-term illness that may lead to chronic infection. Chronic Hepatitis B virus infection is a long-term illness that can result in long-term health problems, such as cirrhosis of the liver, liver cancer, and death.
  • HBV Hepatitis B virus
  • Hepatitis B is usually spread through transfer of a body fluid by sexual contact with an infected person, or through sharing needles for drug-injection. It can also be passed from an infected mother to her baby at birth. In endemic areas, Hepatitis B is most often spread from mother to child at birth, or by exposure to infected blood, especially from an infected child to an uninfected child during the first 5 years of life.
  • Hepatitis B defined as Hepatitis B surface antigen positive for at least 6 months. Approximately 780,000 persons die each year from Hepatitis B infection.
  • hepatitis B infection can be done by detecting the hepatitis B surface antigen HBsAg.
  • Acute hepatitis B virus infection is characterized by the presence of HBsAg and immunoglobulin M (IgM) antibody to the core antigen, HBcAg.
  • IgM immunoglobulin M
  • HBeAg is usually a marker of high levels of replication of the virus. The presence of HBeAg indicates that the blood and body fluids of the infected individual are highly contagious.
  • Chronic infection is characterized by the persistence of HBsAg for at least 6 months, with or without concurrent HBeAg. Persistence of HBsAg is the principal marker of risk for developing chronic liver disease and liver cancer later in life.
  • HBV is a member of the hepadnavirus family.
  • the virus particles which can infect liver cells, are 30-42 nm in diameter and have an outer envelope and an icosahedral nucleocapsid core.
  • the nucleocapsid encloses the viral DNA, and a DNA polymerase that can have reverse transcriptase activity.
  • the outer envelope contains proteins that can be involved in viral binding and entry into cells.
  • HBV has four identified genes, C, P, S, and X.
  • Gene C codes for a core protein, HBcAg.
  • An extracellular protein HBeAg is processed from a pre-core protein.
  • a DNA polymerase is encoded by gene P.
  • Gene S codes for the small surface antigen HBsAg, which is one of three polypeptide surface proteins: large, middle, and small.
  • Gene X may be associated with development of liver cancer.
  • HBV is a pararetrovirus, which is a non-retrovirus that uses reverse transcription in the replication process.
  • the virus can enter the cell and multiply using RNA made by a host process.
  • the viral genomic DNA can be transferred to the cell nucleus, acted upon by viral polymerase, and provide transcription of four viral mRNAs by host RNA polymerase.
  • a large viral mRNA is used to make the new copies of the genome by reverse transcription, and to make the core protein and the viral DNA polymerase.
  • the viral mRNAs are further processed to form new virus particles.
  • HBV can be described by four major serotypes based on epitopes presented by envelope proteins: adr, adw, ayr, ayw. HBV has been identified with eight genotypes, A-H, as well as subgenotypes. The genotypes can have distinct geographical distribution, and are used in tracking evolution and transmission of the virus.

Description

    SEQUENCE LISTING
  • This application includes a Sequence Listing submitted electronically as an ASCII file named ARC1410US_SL.txt.
    • BACKGROUND OF THE INVENTION
  • Hepatitis B is a liver disease that results from infection with the Hepatitis B virus (HBV). Its severity can be from a mild illness lasting a few weeks, to a serious, lifelong illness. Hepatitis B can be either acute or chronic. Acute Hepatitis B virus infection is a short-term illness that may lead to chronic infection. Chronic Hepatitis B virus infection is a long-term illness that can result in long-term health problems, such as cirrhosis of the liver, liver cancer, and death.
  • Hepatitis B is usually spread through transfer of a body fluid by sexual contact with an infected person, or through sharing needles for drug-injection. It can also be passed from an infected mother to her baby at birth. In endemic areas, Hepatitis B is most often spread from mother to child at birth, or by exposure to infected blood, especially from an infected child to an uninfected child during the first 5 years of life.
  • According to the latest WHO estimates, as many as 240 million people are chronically infected with Hepatitis B, defined as Hepatitis B surface antigen positive for at least 6 months. Approximately 780,000 persons die each year from Hepatitis B infection.
  • There is no specific treatment for acute hepatitis B. Chronic hepatitis B infection can be treated with drugs, including oral antiviral agents. WHO recommends the use of oral treatments such as tenofovir or entecavir. In most people, the treatment suppresses replication of the virus, but does not cure hepatitis B infection. Liver cancer progresses rapidly, and treatment options are limited. Surgery and chemotherapy, or liver transplantation can prolong life for up to a few years.
  • Laboratory diagnosis of hepatitis B infection can be done by detecting the hepatitis B surface antigen HBsAg. Acute hepatitis B virus infection is characterized by the presence of HBsAg and immunoglobulin M (IgM) antibody to the core antigen, HBcAg. During the initial phase of infection, patients are also seropositive for hepatitis B e-antigen (HBeAg). HBeAg is usually a marker of high levels of replication of the virus. The presence of HBeAg indicates that the blood and body fluids of the infected individual are highly contagious. Chronic infection is characterized by the persistence of HBsAg for at least 6 months, with or without concurrent HBeAg. Persistence of HBsAg is the principal marker of risk for developing chronic liver disease and liver cancer later in life.
  • HBV is a member of the hepadnavirus family. The virus particles, which can infect liver cells, are 30-42 nm in diameter and have an outer envelope and an icosahedral nucleocapsid core. The nucleocapsid encloses the viral DNA, and a DNA polymerase that can have reverse transcriptase activity. The outer envelope contains proteins that can be involved in viral binding and entry into cells.
  • In general, HBV has four identified genes, C, P, S, and X. Gene C codes for a core protein, HBcAg. An extracellular protein HBeAg is processed from a pre-core protein. A DNA polymerase is encoded by gene P. Gene S codes for the small surface antigen HBsAg, which is one of three polypeptide surface proteins: large, middle, and small. Gene X may be associated with development of liver cancer.
  • HBV is a pararetrovirus, which is a non-retrovirus that uses reverse transcription in the replication process. The virus can enter the cell and multiply using RNA made by a host process. The viral genomic DNA can be transferred to the cell nucleus, acted upon by viral polymerase, and provide transcription of four viral mRNAs by host RNA polymerase. A large viral mRNA is used to make the new copies of the genome by reverse transcription, and to make the core protein and the viral DNA polymerase. The viral mRNAs are further processed to form new virus particles.
  • HBV can be described by four major serotypes based on epitopes presented by envelope proteins: adr, adw, ayr, ayw. HBV has been identified with eight genotypes, A-H, as well as subgenotypes. The genotypes can have distinct geographical distribution, and are used in tracking evolution and transmission of the virus.
  • What is needed are compositions and methods for treatment of Hepatitis B.
  • There is an urgent need for new methods and compositions for ameliorating or treating Hepatitis B infection.

    •  DETAILED DESCRIPTION OF THE INVENTION
  • This invention provides a range of novel agents and compositions to be used as therapeutics against Hepatitis B infection. Molecules of this invention can be used as active pharmaceutical ingredients in compositions for ameliorating, preventing or treating Hepatitis B infection.
  • The galenic molecules of this invention can prevent Hepatitis B virus from carrying out one or more of its processes. Molecules of this invention can be used for ameliorating or treating Hepatitis B infection, and may act against any of the replication, maturation, growth, or transmission modes of the Hepatitis B virus.
  • Novel agents of this invention include oligomeric molecules that inhibit expression of an HBV genome.
  • Embodiments of this invention can provide extraordinary and surprisingly enhanced efficacy against HBV infection in a subject by attacking all portions of the HBV genome. More particularly, agents and compositions of this invention can simultaneously inhibit all identified genes of HBV: C, P, S, and X. Thus, the compounds and compositions of this disclosure can inhibit the small surface antigen HBsAg, as well as the extracellular protein HBeAg, in addition to X protein and viral polymerase.
  • The properties of the compounds of this invention arise according to their molecular structure, and the structure of the molecule in its entirety, as a whole, can provide significant benefits based on those properties. Embodiments of this invention can provide molecules having one or more properties that advantageously provide enhanced effectiveness against HBV, as well as compositions or formulations for therapeutic agents against Hepatitis B infection, which can provide clinical agents.
  • A wide range of novel molecules are provided, each of which can incorporate specialized linker groups. The linker groups can be attached in a chain in the molecule. Each linker group can also be attached to a nucleobase.
  • In some aspects, a linker group can be a monomer. Monomers can be attached to form a chain molecule. In a chain molecule of this invention, a linker group monomer can be attached at any point in the chain.
  • In certain aspects, linker group monomers can be attached in a chain molecule of this invention so that the linker group monomers reside near the ends of the chain. The ends of the chain molecule can be formed by linker group monomers.
  • As used herein, a chain molecule can also be referred to as an oligomer.

In some embodiments, the active oligomer molecule can be double-stranded.
  • Without wishing to be bound by any one particular theory, it is believed that a cellular pathway may use active oligomers of this invention to be sequence-specific regulators in an RNA interference pathway. The active oligomers may bind to the RNA-induced silencing complex (RISC complex), where a sense strand, also referred to as the passenger strand, and an antisense strand, also referred to as the guide strand, can be unwound, and the antisense strand complexed in the RISC complex. The guide strand can bind to a complementary sequence to which it was targeted, for example, a target sequence in an mRNA, which can be subsequently cleaved, resulting in inactivation of the nucleic acid molecule containing the target sequence. As a result, the expression of mRNA containing the target sequence can be reduced.
  • In some embodiments, an oligomeric molecule may be attached to a delivery moiety. Examples of delivery moieties include glycoprotein receptors, galactoses, galactosamines, N-acetylgalactosamines, GalNAc groups, cholesterols, sterols, phytosterols, steroids, zoosterols, lanosterols, stigmastanols, dihydrolanosterols, zymosterols, zymostenols, desmosterols, and 7-dehydrocholesterol s.

  • UNA Monomers
  • In some embodiments, linker group monomers can be unlocked nucleomonomers (UNA monomers), which are small organic molecules based on a propane-1,2,3-tri-yl-trisoxy structure as shown below:
  • Figure US20170016000A1-20170119-C00001
  • where R1 and R2 are H, and R1 and R2 can be phosphodiester linkages, Base can be a nucleobase, and R3 is a functional group described below.
  • In another view, the UNA monomer main atoms can be drawn in IUPAC notation as follows:
  • Figure US20170016000A1-20170119-C00002
  • where the direction of progress of the oligomer chain is from the 1-end to the 3-end of the propane residue.
  • Examples of a nucleobase include uracil, thymine, cytosine, 5-methylcytosine, adenine, guanine, inosine, and natural and non-natural nucleobase analogues.
  • In general, because the UNA monomers are not nucleotides, they can exhibit at least four forms in an oligomer. First, a UNA monomer can be an internal monomer in an oligomer, where the UNA monomer is flanked by other monomers on both sides. In this form, the UNA monomer can participate in base pairing when the oligomer is a duplex, for example, and there are other monomers with nucleobases in the duplex.
  • Examples of UNA monomer as internal monomers flanked at both the propane-1-yl position and the propane-3-yl position, where R3 is —OH, are shown below.
  • Figure US20170016000A1-20170119-C00003
  • Second, a UNA monomer can be a monomer in an overhang of an oligomer duplex, where the UNA monomer is flanked by other monomers on both sides. In this form, the UNA monomer does not participate in base pairing. Because the UNA monomers are flexible organic structures, unlike nucleotides, the overhang containing a UNA monomer will be a flexible terminator for the oligomer.
  • A UNA monomer can be a terminal monomer in an overhang of an oligomer, where the UNA monomer is attached to only one monomer at either the propane-1-yl position or the propane-3-yl position. In this form, the UNA monomer does not participate in base pairing. Because the UNA monomers are flexible organic structures, unlike nucleotides, the overhang containing a UNA monomer can be a flexible terminator for the oligomer.
  • Examples of a UNA monomer as a terminal monomer attached at the propane-3-yl position are shown below.
  • Figure US20170016000A1-20170119-C00004
  • Because a UNA monomer can be a flexible molecule, a UNA monomer as a terminal monomer can assume widely differing conformations. An example of an energy minimized UNA monomer conformation as a terminal monomer attached at the propane-3-yl position is shown below.
  • Figure US20170016000A1-20170119-C00005
  • Thus, UNA oligomers having a terminal UNA monomer are significantly different in structure from conventional nucleic acid agents, such as siRNAs. For example, siRNAs may require that terminal monomers or overhangs in a duplex be stabilized. In contrast, the conformability of a terminal UNA monomer can provide UNA oligomers with different properties.
  • Among other things, the structure of the UNA monomer allows it to be attached to naturally-occurring nucleotides. A UNA oligomer can be a chain composed of UNA monomers, as well as various nucleotides that may be based on naturally-occurring nucleosides.
  • In some embodiments, the functional group R3 of a UNA monomer can be —OR4, —SR4, —NR4 2, —NH(C═O)R4, morpholino, morpholin-1-yl, piperazin-1-yl, or 4-alkanoyl-piperazin-1-yl, where R4 is the same or different for each occurrence, and can be H, alkyl, a cholesterol, a lipid molecule, a polyamine, an amino acid, or a polypeptide.
  • The UNA monomers are organic molecules. UNA monomers are not nucleic acid monomers or nucleotides, nor are they naturally-occurring nucleosides or modified naturally-occurring nucleosides.
  • A UNA oligomer of this invention is a synthetic chain molecule. A UNA oligomer of this invention is not a nucleic acid, nor an oligonucleotide.
  • In some embodiments, as shown above, a UNA monomer can be UNA-A (designated Ã), UNA-U (designated Ũ), UNA-C(designated {hacek over (C)}), and UNA-G (designated {hacek over (G)}).
  • Designations that may be used herein include mA, mG, mC, and mU, which refer to the 2′-O-Methyl modified ribonucleotides.
  • Designations that may be used herein include lower case c and u, which refer to the 2′-O-methyl modified ribonucleotides.
  • Designations that may be used herein include dT, which refers to a 2′-deoxy T nucleotide.
  • Additional Monomers for Oligomeric Agents
  • As used herein, in the context of oligomer sequences, the symbol X represents a UNA monomer.
  • As used herein, in the context of oligomer sequences, the symbol N represents any natural nucleotide monomer, or a modified nucleotide monomer.
  • As used herein, in the context of oligomer sequences, the symbol Q represents a non-natural, modified, or chemically-modified nucleotide monomer. When a Q monomer appears in one strand of the oligomer, and is unpaired with the other strand, the monomer can have any base attached. When a Q monomer appears in one strand of the oligomer, and is paired with a monomer in the other strand, the Q monomer can have any base attached that would be complementary to the monomer in the corresponding paired position in the other strand.

  • wherein L1 is a linkage, n is from 19 to 29, and for each occurrence L2 is a UNA linker group having the formula —C1—C2—C3—, where R is attached to C2 and has the formula —OCH(CH2R3)R5, where R3 is —OR4, —SR4, —NR4 2, —NH(C═O)R4, morpholino, morpholin-1-yl, piperazin-1-yl, or 4-alkanoyl-piperazin-1-yl, where R4 is the same or different for each occurrence and is H, alkyl, a cholesterol, a lipid molecule, a polyamine, an amino acid, or a polypeptide, and where R5 is a nucleobase, or L2(R) is a sugar such as a ribose and R is a nucleobase, or L2 is a modified sugar such as a modified ribose and R is a nucleobase. In certain embodiments, a nucleobase can be a modified nucleobase. L1 can be a phosphodiester linkage.
  • A UNA oligomer of this invention can be a short chain molecule. A UNA oligomer can be a duplex pair. Thus, a UNA oligomer can have a first strand of the duplex and a second strand of the duplex, which is complementary to the first strand with respect to the nucleobases, although up to three mismatches can occur. A UNA oligomer duplex can have overhangs.
  • Some UNA oligomers are discussed in U.S. Pat. No. 8,314,227, as well as US Patent Publication No. 20110313020 A1.
  • The target of a UNA oligomer can be a target nucleic acid. In some embodiments, the target can be any mRNA of a subject. A UNA oligomer can be active for gene silencing in RNA interference.
  • A UNA oligomer may comprise two strands that together provide a duplex. The duplex may be composed of a first strand, which may also be referred to as a passenger strand or sense strand, and a second strand, which may also be referred to as a guide strand or antisense strand.
  • In some aspects, a UNA oligomer of this invention can have any number of phosphorothioate intermonomer linkages in any position in any strand, or in both strands of a duplex structure.
  • In some embodiments, any one or more of the intermonomer linkages of a UNA oligomer can be a phosphodiester, a phosphorothioate including dithioates, a chiral phosphorothioate, and other chemically modified forms.
  • Examples of UNA oligomers of this invention include duplex pairs, which are in general complementary. Thus, for example, SEQ ID NO:1 can represent a first strand of a duplex and SEQ ID NO:2 can represent a second strand of the duplex, which is complementary to the first strand.
  • For example, the symbol “N” in the first strand can represent any nucleotide that is complementary to the monomer in the corresponding position in the second strand. Example UNA oligomers of this disclosure are shown with 2-monomer length overhangs, although overhangs of from 1 to 8 monomers, or longer, can be used.
  • The symbol “X” in a strand or oligomer represents a UNA monomer. When a UNA monomer appears in one strand of the oligomer, and is unpaired with the other strand, the monomer can have any base attached. When a UNA monomer appears in one strand of the oligomer, and is paired with a monomer in the other strand, the UNA monomer can have any base attached that would be complementary to the monomer in the corresponding paired position in the other strand.
  • Further, when the oligomer terminates in a UNA monomer, the terminal position has a 1-end, according to the positional numbering shown above, instead of a 5′-end as for a nucleotide, or the terminal position has a 3-end, according to the positional numbering shown above, instead of a 3′-end as for a nucleotide. For example, the UNA oligomer

    3-X·X·N·N·N·N·N·N·N·N·N-N·N·X·X·X·X·X·X·X·N-5′

    has a UNA monomer 1-end on the first strand, a UNA monomer 3-end on the first strand, a UNA monomer 3-end on the second strand, and a nucleotide 5′-end on the second strand.
  • Complementarity of strands can involve mismatches. In certain embodiments, complementarity of strands can include one to three, or more, mismatches.
  • In some embodiments, a UNA oligomer of this invention can have one or more UNA monomers at the 1-end of the first strand, and one or more UNA monomers at the 3-end of the first strand.
  • In further embodiments, a UNA oligomer of this invention can have one or more UNA monomers at the 3-end of the second strand.
  • In certain embodiments, a duplex UNA oligomer of this invention can have one or more UNA monomers at the 1-end of the first strand, one or more UNA monomers at the 3-end of the first strand, and one or more UNA monomers at the 3-end of the second strand.

  • A UNA oligomer of this invention for inhibiting gene expression can have a first strand and a second strand, each of the strands being 19-29 monomers in length. The monomers can be UNA monomers and nucleic acid nucleoside monomers. The oligomer can have a duplex structure of from 14 to 29 monomers in length. The UNA oligomer can be targeted to a target gene and can exhibit reduced off-target effects as compared to a conventional siRNA. In some embodiments, a UNA oligomer of this invention can have a first strand and a second strand, each of the strands being 19-23 monomers in length.
  • In another aspect, the UNA oligomer may have a blunt end, or may have one or more overhangs. In some embodiments, the first and second strands may be connected with a connecting oligomer in between the strands, and form a duplex region with a connecting loop at one end.
  • In certain embodiments, an overhang can be one or two monomers in length.
  • Examples of an overhang can contain one or more UNA monomers, natural nucleotides, non-natural nucleotides, modified nucleotides, or chemically-modified nucleotides, and combinations thereof.
  • Examples of an overhang can contain one or more deoxythymidine nucleotides, 2′-O-methyl nucleotides, inverted abasic monomers, inverted thymidine monomers, L-thymidine monomers, or glyceryl nucleotides.
  • A UNA oligomer can mediate cleavage of a target nucleic acid in a cell. In some processes, the second strand of the UNA oligomer, at least a portion of which can be complementary to the target nucleic acid, can act as a guide strand that can hybridize to the target nucleic acid.
  • The second strand can be incorporated into an RNA Induced Silencing Complex (RISC).
  • A UNA oligomer of this disclosure may comprise naturally-occurring nucleic acid nucleotides, and modifications thereof that are compatible with gene silencing activity.
  • In some aspects, a UNA oligomer is a double stranded construct molecule that is able to inhibit gene expression.
  • As used herein, the term strand refers to a single, contiguous chain of monomers, the chain having any number of internal monomers and two end monomers, where each end monomer is attached to one internal monomer on one side, and is not attached to a monomer on the other side, so that it ends the chain.
  • The monomers of a UNA oligomer may be attached via phosphodiester linkages, phosphorothioate linkages, gapped linkages, and other variations.
  • In some embodiments, a UNA oligomer can include mismatches in complementarity between the first and second strands. In other embodiments, a UNA oligomer may have 1, or 2, or 3 mismatches. The mismatches may occur at any position in the duplex region.
  • The target of a UNA oligomer can be a target nucleic acid of a target gene.

    • HBV Component Target Sequences
  • As used herein, “Ref Pos” refers to reference position, which is the numerical position of a reference nucleotide in an HBV genome. The reference position is the position that corresponds target-wise to the 5′ end of the sense strand of the oligomeric compound of this invention. The reference positions are numerical nucleotide positions based on a reference genome, which as used herein is HBV Genotype A2, Accession No. HE974376. Thus, a reference position number by itself refers to one sequence from the reference genome, and each sequence can be used in an oligomeric compound of this invention. Table 14 shows genomic positions for the HBV reference genome.

  • In FIG. 1 is shown a map of HBV protein coding regions and selected transcripts for the reference genome HE974376. Nucleotide position 1/3221 is designated at the top. Further designations are as follows: pre-S1, large HBsAg; pre-S2, medium HBsAg; S, HBsAg; P, polymerase; X, HBx protein; pre-C, pre-core/HBeAg; C, HB core Ag. The 2.4 kb, 2.1 kb, and 0.7 kb transcripts coding for the pre-S1/pre-S2/S, as well as the transcript coding the X protein are shown. The pre-Core/HBeAg protein is generated from a long, 3.5 kb transcript (not shown) originating at position ˜1700, while the core and polymerase proteins and the pre-genomic RNA used as a template for viral replication are generated from a ˜200 nt shorter transcript.
  • The ranges of reference positions for certain UNA oligomers, designated UNA oligomer 1, UNA oligomer 2, and UNA oligomer 3, are shown in FIG. 1.
  • In some aspects, the inventive oligomers of this disclosure may target the long transcript coding for HBV core and polymerase proteins.
  • UNA Oligomers Targeting HBV
  • Examples of base sequences of this invention targeted to an HBV component are shown in Table 15.
  • An oligomeric compound of this invention can be formed having a first strand and a second strand each being 21 monomers in length. The first strand can have 19 contiguous monomers with a sequence of attached bases shown in Table 15 (sense), and two additional overhang monomers on the 3′ end. The second strand can have 19 contiguous monomers with a sequence of attached bases shown in Table 15 (antisense), and two additional overhang monomers on the 3′ end. The overhang monomers can be any of NN, QQ, XX, NX, NQ, XN, XQ, QN, and QX. For example, XQ can be UNA-U/mU, or UNA-U/*/dT.
  • An oligomeric compound of this invention can be composed of monomers. The monomers can have attached bases. An oligomeric compound of this invention can have a sequence of attached bases. The sequences of bases shown in Table 15 do not indicate to which monomer each of the bases in the sequence is attached. Thus, each sequence shown in Table 15 refers to a large number of small molecules, each of which is composed of UNA monomers, as well as nucleic acid monomers.
  • In some aspects, an oligomeric compound of this invention can be described by a sequence of attached bases, for example as shown in Table 15, and being substituted forms thereof. As used herein, substituted forms include differently substituted UNA monomers, as well as differently substituted or modified nucleic acid monomers, as are further described herein.
  • In some embodiments, one or more of three monomers at each end of each strand can be connected by a phosphorothioate, a chiral phosphorothioate, or a phosphorodithioate linkage.
  • For example, a compound may have one phosphorothioate linkage between two monomers at the 5′ end of the first strand, one phosphorothioate linkage between two monomers at the 3′ end of the first strand, one phosphorothioate linkage between monomers at the second and third positions from the 3′ end of the first strand, and one phosphorothioate linkage between two monomers at the 3′ end of the second strand.
  • In certain embodiments, a compound may have two or three phosphorothioate linkages at the 5′ end of the first strand, two or three phosphorothioate linkages at the 3′ end of the first strand, and one phosphorothioate linkage at the 3′ end of the second strand.
  • In additional embodiments, a compound may have one to three phosphorothioate linkages at the 5′ end of the first strand, two or three phosphorothioate linkages at the 3′ end of the first strand, two phosphorothioate linkages at the 5′ end of the second strand, and two phosphorothioate linkages at the 3′ end of the second strand.
  • In some examples, a compound may have a deoxythymidine nucleotide at the 3′ end of the first strand, at the 3′ end of the second strand, or at both the 3′ end of the first strand and the 3′ end of the second strand.
  • In some aspects, a compound may contain one to five UNA monomers.
  • In certain aspects, a compound may contain three UNA monomers.
  • In some embodiments, a compound may contain a UNA monomer at the 1-end of the first strand (5′ end), a UNA monomer at the 3-end of the first strand (3′ end), and a UNA monomer at the second position from the 3′ end of the second strand.
  • In certain embodiments, a compound may contain a UNA monomer at any one or more of positions 2 to 8 from the 5′ end of the second strand (seed region).

    • EXAMPLES Example 1 Luciferase Reporter Assay
  • Luciferase-based reporter plasmid was constructed based on psiCHECK™2 vector (Promega, Madison, Wis.). Reporter p(1-20) was generated with oligonucleotides containing the sequence from position 1 through 2500 relative to Eco RI digestion site cloned into the multiple cloning region downstream of the stop codon of the SV40 promoted Renilla luciferase gene in psiCHECK™2, which made the expression of Renilla luciferase gene under the regulation of the artificial 3′UTR sequence. Renilla luciferase activity was then used as an indicator of the effect of the artificial 3′UTR on transcript stability and translation efficiency. The psiCHECK™-2 Vector also contained a constitutively expressed Firefly luciferase gene, which served as an internal control to normalize transfection efficiency.
  • A total of 5,000 HepB3 cells (American Type Culture Collection) were plated onto a well of 96-well plate one day before the transfectrion. The cells were incubated at 37° C. in 100 μl of DMEM (Life Technologies, Carlsbad, Calif.) supplemented with 0.1 mM nonessential amino acids and 10% FBS (Life Technologies, Carlsbad, Calif.). The culture medium was changed to 90 μl of fresh medium just before the transfection. The reporter plasmid and UNA Oligomer were co-transfected with transfection reagent, Lipofectamine™ 3000 (Life Technologies, Carlsbad, Calif.) was used to transfect reporter plasmid (100 ng) and a various amount of UNA Oligomer together with P3000 into the cells according to manufacturer's instruction.
  • Dual-Luciferase Reporter Assay System (DLR assay system, Promega, Madison, Wis.) was used to perform dual-reporter assays on psiCHECK2 based reporter systems. Twenty-four hours after transfection, the cells were washed gently with phosphate buffered saline once. A 50 μl well of Passive Lysis Buffer (Promega, Madison, Wis.) was added to the cells and incubated with gentle rocking for 20 min at room temperature. Luciferase activities were measured using Cytation 3 imaging reader (BioTek, Winooski, Vt.) and the effect of the UNA Oligomer on reporter expression was calculated based on ratio of Renilla/Firefly to normalize cell number and transfection efficiency.
