Crystal structure of human caspase-1 in complex with 4-oxo-3-{6-[4-(quinoxalin-2-yloxy)-benzoylamino]-2-thiophen-2-yl-hexanoylamino}-butyric acid
Overview
Disulfide Tethering was applied to the active site of human caspase-1, resulting in the discovery of a novel, tricyclic molecular fragment that selectively binds in S4. This fragment was developed into a class of potent inhibitors of human caspase-1. Several key analogues determined the optimal distance of the tricycle from the catalytic residues, the relative importance of various features of the tricycle, and the importance of the linker.
