SKI II demonstrates significantly antiproliferative effects in human cancer cell lines including T-24, MCF-7, MCF-7/VP, NCI/ADR with IC50 of 4.6 μM , 1.2 μM, 0.9 μM and 1.3 μM, respectively. SKI II also induces apoptosis of T24 cells consistent with the hypothesized consequence of reducing S1P levels. As demonstrated previously in MDA-MB-231 cells, SKI II decreases S1P formation in JC cells in a concentration-dependent manner, with IC50 of 12 μM. In addition, SKI-II can reverse drug resistance of SGC7901/DDP to cisplatin by down-regulating expression of P-gp and up-regulating apoptosis through down-regulation of SphK1. 体内研究:SKI II (50 mg/kg) after intraperitoneal or oral administration significantly decreases tumor growth a syngeneic Balb/c mouse solid tumor model that uses JC mammary adenocarcinoma cells relative to control groups with no overt toxicity or weight loss. SKI-II (50 mg/kg ip) ameliorates antigen-induced bronchial smooth muscle hyperresponsiveness in mice by endogenously inhibiting generation of S1P. 产品信息订购:
