摘要:
The present invention relates to cysteine protease inhibitors of the general formula (I): ##STR1## wherein Z is a cysteine protease binding moiety; X and Y are S, O or optionally substituted N; and R.sub.1 is optionally substituted alkyl or aryl.
摘要:
The invention provides a method of synthesizing N-substituted 1,4-piperazines and N-substituted 1,4-piperazinediones. The invention also provides a method for synthesing combinatorial libraries of piperazine derivatives which can be assayed for biological activity in pre-specified ligand binding or enzymatic activity screens.
