Antifibrotic agent; inhibits fibrosis by targeting the MRTF/SRF gene transcription pathway. Selectively inhibits proliferation of SSc-derived dermal fibroblasts but not that of normal fibroblasts. Inhibits expression of CTGF, α-SMA, and COL1A2 in SSc fibroblasts as well as in LPA and in TGFβ-stimulated fibroblasts. Prevents bleomycin-induced skin thickening and collagen deposition in vivo. Also suppresses PC-3 cell migration in scratch wound assays (IC50 = 4.2 μM). Purity 98%. MW (observed): 408.88
