BMS-817378

Posted by kinasepro on August 1, 2009

A comments to BMS-777607 suggest that this structure is the backup:

O=C(NC1=CC=C(C(F)=C1)OC2=C(C(N)=NC=C2)Cl)C3=CNC=C(C3=O)C4=CC=C(C=C4)F

    any comments on the 4-pyridone like moiety instead of the 4-hydroxy pyridine???

    Better (intramolecular) h-bond acceptor for formation of a pseudo-ring?

    4-pyridone = 4-hydroxypyridine, depending on the solvent you use to take NMR. These things are tautomers, you know

    Perhaps Sks meant 4 pyridone vs 2 pyridone… as is in 777607, and I have not idea. They’ve made a large number of the various permutations, and via trial and error it looks as though these two were the ones that worked out…

    But the phase I trial (NCT00792558) was withdrawn before it started!

    BMS-817378 is the prodrug of BMS-794833
