Azetidinones such as BMS-363131 (2) and BMS-363130 (3), which contain a guanidine group in the C-3 side chain were previously shown to be very potent inhibitors of human tryptase with high selectivity versus other serine proteases, including trypsin. In this letter, we describe the discovery of a number of potent azetidinone tryptase inhibitors in which the guanidine moiety at the ring C-3 position is replaced with primary or secondary amine or aminopyridine functionality. In particular, BMS-354326 (4) is a highly potent tryptase inhibitor (IC50 1.8 nM), which has excellent selectivity against trypsin and most other related serine proteases. (C) 2004 Elsevier Ltd.
