CCG-222740 is an orally active and selective Rho/myocardin-related transcription factor (MRTF) pathway inhibitor^[1]. CCG-222740 is also a potent inhibitor of alpha-smooth muscle actin protein expression. CCG-222740 effectively reduces fibrosis in skin and blocks melanoma metastasis^[2].

Rho/MRTF pathway^[1]

CCG-222740 (10, 20 μM; for 72 hours) increases the protein levels of p27 and decreases cyclin D1. CCG-222740 decreases cell viability of CAFs, with an IC₅₀ of ~10 μM^[1].
CCG-222740 (10, 25 μM) is potent at decreasing αSMA protein expression in human conjunctival fibroblasts^[2].
CCG-222740 has an IC₅₀ of 5 μM in a fibroblast-mediated collagen contraction assay, and it is less cytotoxic^[2].
