| Bioactivity | CCG-203971 is a second-generation Rho/MRTF/SRF pathway inhibitor. CCG-203971 potently targets RhoA/C-activated SRE-luciferase (IC50 =6.4 μM). CCG-203971 inhibits PC-3 cell migration with an IC50 of 4.2 μM. Potential anti-metastasis Agent[1][2]. | ||||||||||||

| Invitro | CCG-203971, a second-generation Ras homolog gene family, member A (RhoA)/myocardin-related transcription factor A (MRTF-A)/serum response factor (SRF) pathway inhibitor, represses both matrix-stiffness and transforming growth factor beta–mediated fibrogenesis as determined by protein and gene expression in a dose-dependent manner. CCG-203971 significantly represses TGF-β- induced MKL1 expression at 25 μM concentration[2]. Human dermal fibroblasts are plated onto 96-well plates and allowed to grow for 3 days in the presence of 30 μM CCG-203971 or DMSO vehicle. Viable cell density is assessed through enzymatic reduction of the water-soluble tetrazolium dye WST-1. Scleroderma dermal fibroblasts proliferate faster than normal cells, and this is inhibited by CCG-203971[3]. | ||||||||||||
| In Vivo | CCG-203971 is tested in a Bleomycin skin injury model. Bleomycin is administered in 50 μL of DMSO intraperitoneally. Preliminary studies show that Bleomycin administered in this manner is well tolerated at 100 mg/kg twice a day. Intradermal Bleomycin for 2 weeks along with the DMSO control (50 μL i.p.) results in marked dermal thickening (P<0.0001) compared with the PBS+DMSO group, which does not receive Bleomycin. CCG-203971 treatment strongly and significantly (P<0.001) suppresses the Bleomycin-induced skin thickening in this model. Skin collagen amounts, assessed by measurement of hydroxyproline content, show similar results. Bleomycin injections promote collagen deposition (P<0.01) and CCG-203971 is able to block this effect (P<0.05)[3]. | ||||||||||||
