Description
(extracted from source data)
DESCRIPTION Potent inducible nitric oxide synthase (iNOS) inhibitor; endothelial NOS (eNOS) inhibitor (LOPAC library)
DESCRIPTION 1,3-PBIT is a potent inhibitor of iNOS with a Ki of 47 nM compared to Ki values for eNOS and nNOS are 9 and 0.25 µM, respectively, for the purified human enzymes. Its inhibition in whole cells is greatly diminished, presumably to poor membrane permeability. 3-PBIT, also known as S,S'-(1,3-Phenylenebis(1,2-ethanediyl))bisisothiourea, is a potent and selective iNOS inhibitor.
