6-Acylamino-penam derivatives: Synthesis and inhibition of cathepsins B, L, K, and S

The synthesis of a new series of 6-acylamino penam derivatives and their inhibition of cysteine proteases cathepsins B, L, K, and S is described. The 6-acylamino-penam sulfone compounds showed excellent cathepsin L, K, and S inhibition activity with ICsu
