Biological target:

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.

In vitro activity:

Candidate MRTF/SRF pathway inhibitor, CCG-203971, was tested using a functional three-dimensional fibroblast-populated collagen contraction assay. This assay was chosen as it has been shown to be a good in vitro model to study tissue contraction. CCG-203971 decreased collagen matrix contraction in a concentration-dependent manner but CCG-222740 was five times more potent than CCG-203971 in human conjunctival fibroblasts [IC50 = 5 μM compared to 25 μM] (Fig. 1A and B). These results were confirmed in rabbit conjunctival fibroblasts, where CCG-222740 was similarly more effective at decreasing collagen matrix contraction than CCG-203971 (Fig. 2A and B). In addition, CCG-222740 was less cytotoxic than CCG-203971 with a cell viability of 100% at 10 μM, 88% at 30 μM, and 85% at 100 μM (Fig. 1C). How CCG-222740 and CCG-203971 affect the activity of an SRF reporter gene was also compared in transfected cells. Both compounds showed similar activity, with almost 100% inhibition of baseline reporter activity (Figs 1D and 2E,F). However, examination of endogenous gene expression revealed that CCG-222740 was a more potent inhibitor of expression for two MRTF/SRF target genes classically linked to fibrosis (ACTA2, coding for alpha-smooth muscle actin – αSMA; and CTGF, coding for Connective Tissue Growth Factor) (Fig. 1E–H). CCG-222740 also decreased ACTA2 gene expression to a greater extent than CCG-203971 in rabbit conjunctival fibroblasts (Fig. 2C and D).

In vivo activity:

To determine whether these effects would translate in vivo, CCG-203971 was tested in a bleomycin skin injury model. Because of its modest solubility, bleomycin was administered in 50 μl of DMSO intraperitoneally. Preliminary studies showed that the compound administered in this manner was well tolerated at 100 mg/kg twice a day. Intradermal bleomycin for 2 weeks along with the DMSO control (50 μl i.p.) resulted in marked dermal thickening (P < 0.0001) compared with the PBS+DMSO group, which did not receive bleomycin (Fig. 5, A–B). CCG-203971 treatment strongly and significantly (P < 0.001) suppressed the bleomycin-induced skin thickening in this model (Fig. 5, A–B). Skin collagen amounts, assessed by measurement of hydroxyproline content, showed similar results. Bleomycin injections promoted collagen deposition (P < 0.01) and CCG-203971 was able to block this effect (P < 0.05, Fig. 5C).
