Application

SR 3677 has been used as Rho-associated kinase (ROCK) inhibitor in cardiac reprogramming.

Biochem/physiol Actions

SR-3677 is a very potent, selective ROCK inhibitor, with higher potency against ROCK II (IC50 = 3 nM) than ROCK I (IC50 = 56 nM). In a kinase screening panel, SR-3677 was shown to only have activity against three other kinases (PKA, MRCK and Akt1) all with IC50 values over 1 μM. The compound has nM potency in cell based assays, and is efficacious in an ex-vivo model for increasing aqueous humor outflow in porcine eyes.
SR3677 decreases amyloid precursor protein (sAPPβ) and amyloid-β (Aβ) in a dose-dependent manner. In 5XFAD mouse brain, SR3677 represses the enzymatic activity of β-site APP cleaving enzyme 1 (BACE1). SR3677 has the ability to change the endocytic supply of BACE1 and induce APP traffic to lysosomes.

Direct reprogramming of fibroblasts into cardiomyocytes by forced expression of cardiomyogenic factors, GMT (GATA4, Mef2C, Tbx5) or GHMT (GATA4, Hand2, Mef2C, Tbx5), has recently been demonstrated, suggesting a novel therapeutic strategy for cardiac repair. However, current approaches are inefficient. Here
