Synthesis and SAR of 4-carboxy-2-azetidinone mechanism-based tryptase inhibitors
摘要:
A series of N1-activated C4-carboxy azetidinones was prepared and tested as inhibitors of human tryptase. The key stereochemical and functional features required for potency, serine protease specificity and aqueous stability were determined. From these studies compound 2, BMS-262084, was identified as a potent and selective tryptase inhibitor which, when dosed intratracheally in ovalbumin-sensitized guinea pigs, reduced allergen-induced bronchoconstriction and inflammatory cell infiltration into the lung.

recent years has led to remarkable achievements in cross-coupling reactions. In this work, we show that a careful selection of the ancillary ligands that complete the catalyst/precatalyst can provide an extra level of performance. Low loadings of [(IPr*)PdCl2(TEA)] IPr* = 1,3-bis[2,6-bis(diphenylmethyl)-4-methylphenyl]imidazole-2-ylidene, TEA = triethylamine} catalyze the Buchwald-Hartwig amination
