NOVEL TRICYCLIC COMPOUNDS
Technical Field
This invention relates to certain novel tricyclic compounds (Formula (1) ) as bromodomain and extra-terminal (BET) inhibitors which is shown as Formula (1) , their synthesis and their use for treating diseases. More particularly, this invention is directed to fused heterocyclic derivatives useful as inhibitors of BET, methods for producing such compounds and methods for treating diseases and conditions wherein inhibition of one or more BET bromodomains provides a benefit.
Background Art
Epigenetics is used to describe heritable gene regulation or transcriptional silencing across generations of cells and even organism and the process of which is mediated through dynamic and reversible changes in chromatin accessibility and post-translational modifications (PTMs) of histone tails. Several physiological processes might contribute to epigenetic regulation, including DNA methylation, non-coding RNA-mediated scaffolding and complex formation, and histone modification. Histone modification is a process related to the post-translational covalent modification of histone proteins that markedly influences the ability of associated DNA to be transcribed. Lysine acetylation is a post-translational modification with broad relevance to cellular signaling and disease biology. Enzymes that regulate lysine acetylation in histones are termed as ‘writers’ or histone acetyltransferaes (HATs) , and that regulating lysine deacetylation in histone as ‘erasers’ or histone deacetylases (HDACs) . Bromodomains (BRDs) , ‘readers’ of epigenetic marks, specifically recognize ε-N-acetyl lysine (Kac) residues on histones tails.
BRDs, first described in 1992, contain approximately 110 amino acids. There are 46 known bromodomain containing proteins from humans which across eight families based on structure/sequence similarity. Among them, bromodomain and extra-terminal domain (BET) recognize acetylated lysine residues in histones H3 and H4. BET family, containing BRD2, BRD3, BRD4 and BRDT four members, share two N-terminal bromodomains and extra C-terminal domain (ET) exhibiting high levels of sequence conservation. As reported, BRD2 and BRD3 associate with histones along actively transcribed genes and maybe involved in facilitating transcriptional elongation (Leroy et al., Mol. Cell 2008 30 (1) ; 51-60) . BRD4 appears to be involved in the recruitment of the positive transcriptional elongation factor complex (pTEF-I3) , which plays an essential role in the regulation of transcription by RNA polymerase and increased transcriptional output (Hargreaves et al., Cell, 2009 138 (1) : 1294145) . Unlike the other three BET proteins expressed ubiquitiously, BRDT expression is normally testis-specific (M.H. Jones et al, Genomics, 1997 (45) , 529-534) and BRDT is essential for spermatogenesis (E. Shang et al, Development, 2007 (134) , 3507-3515) . All BET family members have some function in controlling or executing aspects of the cell cycle, and remain in complex with chromosomes during cell division-implying a role in the maintenance of epigenetic memory. Dysfunction of them have critical roles in a variety of human disease.
Interrupting the protein-protein interactions between BET protein and acetylated lysine becomes a promising target for human diseases including virology, hart failure, inflammation, central nervous system (CNS) disorders and variety cancers. Small molecule BET inhibitors that are reported in development include RVX-208, GSK-525762A, GSK2820151, OTX-015, CPI-0610, TEN-010, ABBV-075, ABBV-74, BI 894999, BMS-986158, INCB054329, ZEN-3694 GS-5829 as well as an inhibitor, CC-90010, from Celgene. There exists a need for generating further BET inhibitors that have improved properties over existing BET inhibitors, for example, improved potency, safety, tolerability, pharmacokinetics and/or pharmocodynamics.

Each tablet preferably contains from about 0.05mg to about 5g of the active ingredient and each cachet or capsule preferably containing from about 0.05mg to about 5g of the active ingredient. For example, a formulation intended for the oral administration to humans may contain from about 0.5mg to about 5g of active agent, compounded with an appropriate and convenient amount of carrier material which may vary from about 5 to about 95 percent of the total composition. Unit dosage forms will generally contain between from about lmg to about 2g of the active ingredient, typically 25mg, 50mg, l00mg, 200mg, 300mg, 400mg, 500mg, 600mg, 800mg, or l000mg.
Pharmaceutical compositions of the present invention suitable for parenteral administration may be prepared as solutions or suspensions of the active compounds in water. A suitable surfactant can be included such as, for example, hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols, and mixtures thereof in oils. Further, a preservative can be included to prevent the detrimental growth of microorganisms.
Pharmaceutical compositions of the present invention suitable for injectable use include sterile aqueous solutions or dispersions. Furthermore, the compositions can be in the form of sterile powders for the extemporaneous preparation of such sterile injectable solutions or dispersions. In all cases, the final injectable form must be sterile and must be effectively fluid for easy syringability. The pharmaceutical compositions must be stable under the conditions of manufacture and storage; thus, preferably should be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol and liquid polyethylene glycol) , vegetable oils, and suitable mixtures thereof.
Pharmaceutical compositions of the present invention can be in a form suitable for topical use such as, for example, an aerosol, cream, ointment, lotion, dusting powder, or the like. Further, the compositions can be in a form suitable for use in transdermal devices. These formulations may be prepared, utilizing a compound represented by Formula of this invention, or a pharmaceutically acceptable salt thereof, via conventional processing methods. As an example, a cream or ointment is prepared by admixing hydrophilic material and water, together with about 5wt%to about 10wt%of the compound, to produce a cream or ointment having a desired consistency.
Pharmaceutical compositions of this invention can be in a form suitable for rectal administration wherein the carrier is a solid. It is preferable that the mixture forms unit dose suppositories. Suitable carriers include cocoa butter and other materials commonly used in the art. The suppositories may be conveniently formed by first admixing the composition with the softened or melted carrier (s) followed by chilling and shaping in molds.
In addition to the aforementioned carrier ingredients, the pharmaceutical formulations described above may include, as appropriate, one or more additional carrier ingredients such as diluents, buffers, flavoring agents, binders, surface-active agents, thickeners, lubricants, preservatives (including antioxidants) and the like. Furthermore, other adjuvants can be included to render the formulation isotonic with the blood of the intended recipient. Compositions containing a compound described by Formula, or pharmaceutically acceptable salts thereof, may also be prepared in powder or liquid concentrate form.
Generally, dosage levels on the order of from about 0.01mg/kg to about 150mg/kg of body weight per day are useful in the treatment of the above-indicated conditions, or alternatively about 0.5mg to about 7g per patient per day. For example, inflammation, cancer, psoriasis, allergy/asthma, disease and conditions of the immune system, disease and conditions of the central nervous system (CNS) , may be effectively treated by the administration of from about 0.01 to 50mg of the compound per kilogram of body weight per day, or alternatively about 0.5mg to about 3.5g per patient per day.
It is understood, however, that the specific dose level for any particular patient will depend upon a variety of factors including the age, body weight, general health, sex, diet, time of administration, route of administration, rate of excretion, drug combination and the severity of the particular disease undergoing therapy.
These and other aspects will become apparent from the following written description of the invention.
