专利号:US-5847150-A 优先权日:1996-04-24 标题 :Solid phase and combinatorial synthesis of substituted 2-methylene-2, 3-dihydrothiazoles and of arrays of substituted 2-methylene-2, 3-dihydrothiazoles 发明人:DORWALD FLORENCIO ZARAGOZA 权利人:NOVO NORDISK AS 摘要:A solid phase method for the synthesis of a plurality of differently substituted 2-methylenethiazoles with a wide variety of side-chain substituents as compounds of potential therapeutic interest. The 2-methylenethiazoles are prepared by acylation of a substrate-bound primary or secondary amine with cyanoacetic acid and reaction of the resulting cyanoacetamide with an isothiocyanate in the presence of a base. Alkylation with an appropriate alkyl halide under acidic conditions yields differently substituted, support-bound 2-methylene-2,3-dihydrothiazoles. These may be screened on the substrate or cleaved from the substrate and then screened in solution. The efficient synthesis of a wide variety of 2-methylenethiazoles using automated synthesis technology of the present method makes these compounds attractive candidates for the generation and rapid screening of diverse thiazole-based libraries. The method disclosed here provides an easy and fast access to highly diverse heterocyclic compounds of therapeutic interest, amenable to automatization.

Also provided are methods for prevention and/or treatment of cancer, Alzheimer's disease, Parkinson's disease, multiple sclerosis, amyotropic lateral sclerosis, rheumatoid arthritis, inflammatory bowel disease, and all other diseases whose pathogenesis is believed to involve excessive production of either nitric oxide (NO) or prostaglandins or the overexpression of iNOS or COX-2 genes or gene products. Further, methods for the synthesis of the TBE compounds of the invention utilize cheap commercially available reagents and are highly cost effective and amenable to scale-up. Additional high efficiency synthetic methods that utilize novel intermediates as well as the synthesis of these intermediates are also provided. Furthermore, the invention also provides methods for designing novel and water-soluble TBEs.

The method comprises (a) reacting an optically pure 1,2-O-dialkyl-sn-glycerol or 1,2-O-dialkyl-sn-glycerol with one or more phosphoramidite reagent(s), wherein a phosphite triester is produced; (b) coupling the product of (a) with glycerol, wherein a protected cardiolipin is produced; and (c) deprotecting the protected cardiolipin, such that cardiolipin is prepared. The cardiolipins and analogues thereof, prepared by the present methods, can be incorporated into liposomes, which can also include active agents such as hydrophobic or hydrophilic drugs, antisense nucleotides or diagnostic agents. Such liposomes can be used to treat diseases or can be used in diagnostic and/or analytical assays.
