N-[2-[2-(二甲基氨基)乙氧基]-4-(1H-吡唑-4-基)苯基]-2,3-二氢-1,4-苯并二恶烷-2-甲酰胺

SR-3677 has an IC ₅₀ of ~3 nM in enzyme and cell based assays and has an off-target hit rate of 1.4% against 353 kinases, and inhibits only 3 out of 70 nonkinase enzymes and receptors. The IC ₅₀ value of SR-3677 for ROCK-I is 56±12 nM. The hydrophobic interaction of the benzodioxane phenyl ring with the hydrophobic surface of the pocket is the dominating factor that contributes to the high potency of SR-3677.

ExVivo: Pharmacology studies shows that SR-3677 is efficacious in both, increasing ex vivo aqueous humor outflow in porcine eyes and inhibiting myosin light chain phosphorylation. Continuous exposure of 25 µM SR-3677 increases the outflow facility by 60% at 1 h perfusion, increasing to 70–80% for the 2–5 h time points.
