摘要:
The identification of a new class of potent and selective ROCK-II inhibitors is presented. Compound 5 (SR-3677) had an IC50 of similar to 3 nM in enzyme and cell based assays and had an off-tar-et hit rate of 1.4% against 353 kinases. and inhibited only 3 out of 70 nonkinase enzymes and receptors. Pharmacology studies showed that 5 was efficacious in both, increasing ex vivo aqueous humor outflow in porcine eves and inhibiting myosin light chain phosphorylation.
