Novel non-peptidic vinylsulfones targeting the S2 and S3 subsites of parasite cysteine proteases
摘要:
We describe here the identification of non-peptidic vinylsulfones that inhibit parasite cysteine proteases in vitro and inhibit the growth of Trypanosoma brucei brucei parasites in culture. A high resolution (1.75 angstrom) co-crystal structure of 8a bound to cruzain reveals how the non-peptidic P2/P3 moiety in such analogs bind the S2 and S3 subsites of the protease, effectively recapitulating important binding interactions present in more traditional peptide-based protease inhibitors and natural substrates.
