It has been found that the compounds of formula I are inhibitors of gamma-secretase (secretase) and related compounds may be useful in the treatment of alzheimer's disease.
Alzheimer's Disease (AD) is the most common cause of dementia in later years. AD is pathologically characterized by the deposition of amyloid in the brain in extracellular plaques and intracellular neurofibrillary tangles. Amyloid plaques are mainly composed of amyloid peptides (Abeta peptides) derived from β -Amyloid Precursor Protein (APP) through a series of proteolytic cleavage steps. Several forms of APP have been identified, the most abundant of which are proteins of 695, 751 and 770 amino acids in length. They are all produced from a single gene by differential splicing. The Abeta peptides are derived from the same domain of APP, but differ at their N-and C-termini, the main species being 40 and 42 amino acids in length.
The Abeta peptide is produced by APP through the sequential action of 2 proteases called β -and γ -secretases. The β -secretase enzyme first cleaves in the extracellular domain of APP outside the transmembrane domain (TM) to produce an APP C-terminal fragment containing the TM-and cytoplasmic domains (CTF β). CTF β is a substrate for γ -secretase, which cleaves at several adjacent positions within the TM to produce a β peptide and cytoplasmic fragments. Most Abeta peptides are 40 amino acids long (a β 40), with a few species carrying 2 additional amino acids at their C-terminus. The latter is presumed to be the more pathogenic amyloid peptide.
The beta-secretase enzyme is typically an aspartyl protease. Gamma-secretase has proteolytic activity and consists of several proteins, the exact composition of which is not completely understood. However, presenilins (presenilins) are essential components of this activity and may represent a new group of atypical aspartyl proteases that cleave within the TM of their substrates and are themselves heterotopic (polytopic) membrane proteins. Other essential components of gamma-secretase may be nicastrin and the products of aph1 and pen-2 genes. Substrates of the demonstrated gamma-secretase are the APP and Notch receptor family proteins, however, gamma-secretase has an unfixed substrate specificity and can also cleave membrane proteins unrelated to APP and Notch.
Gamma-secretase activity is absolutely required for Abeta peptide production. This has been demonstrated by genetic means, i.e., partial excision of the presenilin gene and by low molecular weight inhibitory compounds. Since the production and deposition of Abeta is the ultimate cause of the disease, either according to the amyloid hypothesis or AD, selective and potent inhibitors of γ -secretase are believed to be useful in the prevention and treatment of AD.
Thus, the compounds of the present invention are useful for the treatment of AD by blocking γ -secretase activity and reducing or preventing the formation of various amyloid-derived (amyloidogenic) Abeta peptides.

The mixture was then dissolved in more dichloromethane, washed and dried. After evaporation of the solvent, the compound of the formula II is obtained, for example 2-methyl-N- (5-methyl-6-oxo-6, 7-dihydro-5H-dibenzo [ b, d ]]Aza derivatives-7-yl) -malonamic acid.

The compound of formula I obtained is isolated and purified in a conventional manner.
The compounds of formula I can be converted into the corresponding acid addition salts. The conversion is accomplished by treatment with at least a stoichiometric amount of a suitable acid, such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like, and organic acids, such as acetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, malic acid, malonic acid, succinic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid, and the like. Generally, the free base is dissolved in an inert organic solvent such as diethyl ether, ethyl acetate, chloroform, ethanol or methanol, and the like, and the acid is added in a similar solvent. The temperature was maintained between 0 ℃ and 50 ℃. The resulting salt precipitates spontaneously or can be brought out of solution using a less polar solvent.
The acid addition salts of the compounds of formula I can be converted to the corresponding free bases by treatment with at least a stoichiometric equivalent of a suitable base such as sodium or potassium hydroxide, potassium carbonate, sodium bicarbonate, ammonia, and the like.
The compounds of formula I and their pharmaceutically usable addition salts have valuable pharmacological properties. In particular, it has been found that the compounds of the present invention can inhibit gamma-secretase.
The compounds were studied according to the tests given below.
Description of the Gamma-secretase assay
The activity of a test compound can be evaluated in assays that measure gamma-secretase activity to proteolytically cleave an appropriate substrate. These assays may be cellular assays in which, for example, a substrate for gamma-secretase is fused in its cytoplasmic domain to a transcription factor. Cells are transfected with such fusion genes and reporter genes whose expression is enhanced by transcription factors, such as luciferase. Cleavage of the fusion substrate by gamma-secretase allows expression of the reporter gene to be monitored in a suitable assay. The gamma-secretase activity can also be determined in cell-free in vitro assays, in which, for example, cell lysates containing the gamma-secretase complex are incubated with a suitable APP-derived substrate, which is cleaved to the Abeta peptide. The amount of peptide produced can be determined using a specific ELISA assay. Neuronal derived cell lines secrete Abeta peptides, which can be determined using specific ELISA assays. Treatment with compounds that inhibit γ -secretase results in a reduction in secreted Abeta, thereby providing a measure of inhibition.
In vitro assays for gamma-secretase activity use HEK293 membrane fraction as a source of gamma-secretase and a recombinant APP substrate. The latter consists of the C-terminal 100 amino acids of human APP fused to the 6 histidine tail for purification, which is expressed in E.coli using a regulatable expression vector, such as pEt 15. This recombinant protein corresponds to a truncated APP fragment, which is produced after cleavage of the extracellular domain by gamma-secretase and constitutes the gamma-secretase substrate. The principle of the test is described in PNAS97(11), 6138-. Hek293 cells were mechanically disrupted and the microsomal fraction was isolated by differential centrifugation. The membrane was dissolved in detergent (0.25% CHAPSO) and incubated with APP substrate. The Abeta peptide produced by gamma-secretase cleavage of the substrate was detected by a specific ELISA assay as described (Brockhaus M et al, Neuroreport, 9(7), 1481-1486 (1998)).

The compounds of formula I and the pharmaceutically acceptable salts of the compounds of formula I can be used as medicaments, for example in the form of pharmaceutical preparations. The pharmaceutical preparations can be administered orally, for example in the form of tablets, coated tablets, dragees, hard and soft gelatine capsules, solutions, emulsions or suspensions. However, administration can also be effected rectally, for example in the form of suppositories, parenterally, for example in the form of injection solutions.
The compounds of formula I may be processed with pharmaceutically inert inorganic or organic carriers to prepare pharmaceutical formulations. Lactose, corn starch or derivatives thereof, talc, stearic acid or its salts and the like can be used, for example, as such carriers for tablets, coated tablets, dragees and hard gelatine capsules. Suitable carriers for soft gelatin capsules are, for example, vegetable oils, waxes, fats, semi-solid and liquid polyols and the like. Depending on the nature of the active substance, however, no carriers are generally required in the case of soft gelatin capsules. Suitable carriers for the preparation of solutions and syrups are, for example, water, polyols, glycerol, vegetable oils and the like. Suitable carriers for suppositories are, for example, natural or hardened oils, waxes, fats, semi-liquid or liquid polyols and the like.
Furthermore, the pharmaceutical preparations can contain preservatives, solubilizers, stabilizers, wetting agents, emulsifiers, sweeteners, colorants, flavorants, salts for varying the osmotic pressure, buffers, masking agents or antioxidants. They may also contain other therapeutically valuable substances.
Medicaments containing a compound of formula I or a pharmaceutically acceptable salt thereof and a therapeutically inert carrier are also an object of the present invention, as well as a process for their preparation, which comprises bringing one or more compounds of formula I and/or pharmaceutically acceptable acid addition salts and, if desired, one or more other therapeutically valuable substances into a galenical administration form together with one or more therapeutically inert carriers.
According to the present invention, the compounds of formula I and their pharmaceutically acceptable salts are useful for the control or prevention of diseases, such as alzheimer's disease, based on gamma-secretase inhibition.
The dosage can vary within wide limits and will, of course, be adjusted in each particular case to the individual requirements. In the case of oral administration, the dosage for an adult may be from about 0.01mg to about 1000mg per day of a compound of formula I or a corresponding amount of a pharmaceutically acceptable salt thereof. The daily dose may be administered as a single dose or in divided doses and, in addition, the upper limit may be exceeded when this is found to be necessary.
