Diamino benzo[b]thiophene derivatives as a novel class of active site directed thrombin inhibitors. Part 6: further focus on the contracted C4'-side chain analogues.

Abstract:

:Novel benzo[b]thiophene diamine thrombin inhibitors were investigated, focusing on a contracted C4'-side chain series. SAR studies identified compounds with either a pyrrolidino or morpholino group as potent, active site directed thrombin inhibitors when the amino group was connected to the C3-phenyl ring with a methylene linker at the C4' position of the phenyl ring.
