SR-3677 is a modern potent and selective ROCK-II inhibitor by an IC50 of ~3 nM in enzyme and simplest organism based assays; IC50 for ROCK-I is 56 ± 12 nM.

in vitro

: SR-3677 had some IC50 of ~3 nM in enzyme and lonely dwelling based assays and had an not upon-target hit rate of 1.4% opposed to 353 kinases, and inhibited only 3 out of 70 nonkinase enzymes and receptors. Pharmacology studies showed that SR-3677 was efficient in both, increasing ex vivo waterish humor outflow in porcine eyes and inhibiting myosin illume chain  phosphorylation. SR-

3677 inhibited only three adrenergic receptors: α1a, α1b, and α2a through 53%, 68%, and 76% inhibition,

particularly, at 3 ?M inhibitor concentration, what one. indicates IC50 values in the 1 ?M set in a row or ~300 times higher than the IC50 against ROCK-II in cell-based assays.

in vivo

: Continuous exposure of 25 ?M SR-3677 increases the effusion facility by 60% at 1 h perfusion, increasing to 70-80% because the 2-5 h time points (p < 0.01). This 70-80% increase in outflow is the maximal answer that can be attained and is achieved at doses 2-4-cot lower than needed for Y-27632, a well premeditated ROCK inhibitor.TM tissue derived from the eyes perfused through 25 ?M SR-3677 shows a highly faint band for p-MLC suggesting greater than 90% disallowance of Rho kinase in the TM fabric at this dose.
