  2-Amino-4H-3,1-benzoxazin-4-ones as Inhibitors of C1r Serine Protease

  摘要：

  A series of 2-amino-4H-3,1-benzoxazin-4-ones have been synthesized and evaluated as inhibitors of the complement enzyme C1r. C1r is a serine protease at the beginning of the complement cascade, and complement activation by beta-amyloid may represent a major contributing pathway to the neuropathology of Alzheimer's disease. Compounds such as 7-chloro-2-[(2-iodophenyl)amino]benz[d][1,3]oxazin-4-one (32) and 7-methyl-2-[(2-iodophenyl)amino]benz[d] 4-one (37) show improved potency compared to the reference compound FUT-175. Many of these active compounds also possess increased selectivity for C1r compared to trypsin and enhanced hydrolytic stability relative to 2-(2-iodophenyl)-4H-3,1-benzoxazin-4-one (1).

  The triethylamine-catalyzed reactions of methyl N-(cyanothioformyl)anthranilate (1) with isocyanates result in cyclization involving the cyano group to form methyl 2-(4-imino-2-oxo-3-substituted-5-thioxoimi-dazolidin-1-yl)benzoates (4). Ring closure at the ester carbonyl to form 3-aryl-3,4-dihydro-4-oxoquinazo-line-2-carbonitriles (8) is observed when the S-methyl derivative of 1 is allowed to react
