Calycosin (Cyclosin) is a natural active compound with anti-oxidative and anti-inflammation activity. IC50 value: Target: in vitro: calycosin had obvious anti-proliferation effects on SKOV3 cells in a dose- and time-dependent manner. calycosin up-regulated the Bax/Bcl-2 ratio and cleaved caspase-3, cleaved caspase-9 expression in a dose-dependent manner. In summary, calycosin might exert anti-growth and induce-apoptosis activity against ovariancancerSKOV3 cells through activating caspases andBcl-2 familyproteins, therefore presenting as a promising therapeutic agent for the treatment of ovariancancer[1]. Both calycosin and genistein inhibited proliferation and inducedapoptosisin MCF-7 breastcancercells, especially after treatment with calycosin. Treatment of MCF-7 cells with calycosin or genistein resulted in decreased phosphorylation ofAkt, and decreased expression of its downstream target, HOTAIR [2]. incubation of calycosin resulted in enhanced expressionERβin MCF-7 and T-47D cells, rather than MDA-231 and MDA-435 cells. Moreover, with the upregulation ofERβ, successive changes in downstream signaling pathways were found, including inactivation ofinsulin-like growth factor 1 receptor(IGF-1R), then stimulation ofp38 MAPKand suppression of theserine/threonine kinase(Akt), and finally poly(ADP-ribose) polymerase 1 (PARP-1) cleavage [3]. in vivo: calycosin stimulated a dramatic increase in uterine weight and downregulated the level ofERαprotein in OVX mice [4].
