Dioscin, a natural product isolated and purified from the rhizome of Dioscorea Zingiberensis C.H.Wright, is a potent ITGA5 inhibitor, showing potent anti-cancer effect against a variety of tumor cell lines.
Dioscin is a natural steroid saponin derived from several plants, showing potent anti-cancer effect against a variety of tumor cell lines. Dioscin (1, 2 and 4 μmol/L) could significantly inhibit the viability of LNCaP cells in a time- and concentration-dependent manner[3]. Dioscin suppressed RANKL-mediated osteoclast differentiation and bone resorption in vitro in a dose-dependent manner. Dioscin abrogated AKT phosphorylation, which subsequently impaired RANKL-induced nuclear factor-kappaB (NF-κB) signaling pathway and inhibited NFATc1 transcriptional activity[4]. Oral treatment dioscin delays crystalline silica-induced pulmonary fibrosis and exerts pulmonary protective effects in mice[5]. Dioscin could promote autophagy in macrophages. Dioscin-triggered AMs autophagy limited mitochondrial reactive oxygen species (mtROS) mass stimulated by CS(crystalline silica), reduced mitochondria-dependent apoptosis pathway activation and facilitated cell survival. Dioscin treatment alleviated macrophage-derived inflammation and subsequent abnormal collagen repair[6].
