Structure-based design of inhibitors of coagulation factor XIa with novel P1 moieties.
Bioorg.Med.Chem.Lett., 25:1635-1642, 2015

PubMed Abstract: Compound 2 was previously identified as a potent inhibitor of factor XIa lacking oral bioavailability. A structure-based approach was used to design analogs of 2 with novel P1 moieties with good selectivity profiles and oral bioavailability. Further optimization of the P1 group led to the identification of a 4-chlorophenyltetrazole P1 analog, which when combined with further modifications to the linker and P2' group provided compound 32 with FXIa Ki=6.7 nM and modest oral exposure in dogs.
