化合物SC144 T6207

Product Introduction
Bioactivity


英文名: SC144

描述: SC144 是一种口服活性 gp130 抑制剂。它结合 gp130，诱导 gp130 磷酸化(S782) 和去糖基化，消除 Stat3 磷酸化和核易位，进一步抑制下游靶基因的表达。它对 gp130 配体触发的信号转导有明显的抑制作用，可诱导人卵巢癌细胞凋亡。

细胞实验: MTT assay (Only for Reference)

体外活性: SC144 exhibits potent cytotoxicity against a panel of drug-sensitive and drug-resistant cancer cell lines. SC144 shows synergism with both 5-fluorouracil and oxaliplatin when co-treated in colorectal cancer HT29 cells. Pretreatment with SC144 in oxaliplatin-resistant HTOXAR3 cells is more effective than oxaliplatin pretreatment. In addition, the combination of SC144 and paclitaxel exhibited synergism in MDA-MB-435 cells with a schedule-dependent block in cell cycle. [1] SC144 treatment in vitro induces gp130 phosphorylation and deglycosylation, resulting in the downregulation of surface-bound gp130 and the abrogation of gp130-associated Stat3 activation. In addition, SC144 selectively inhibits the downstream signaling activation induced by gp130 substrates, including IL-6 and LIF. Protein expression regulated by the gp130/Stat3 axis in OVCAR-8 cells is also down-regulated after SC144 treatment, including Bcl-2, Bcl-XL, survivin, cyclin D1, MMP-7, gp130 and Ape1/Rel-1. [2]

体内活性: SC144 significantly inhibits tumor growth in a mouse xenograft model of human ovarian cancer via i.p. or p.o. administration. After SC144 treatment for two months, gp130, Bcl-2, Bcl-XL, MMP-7 and Ape1/Ref-1 protein levels are substantially decreased in the tumor site in the treatment group compared with the control group. [2] In an MDA-MB-435 mouse xenograft model, co-administration of SC144 and paclitaxel delays tumor growth in an SC144 dose-dependent manner. Evaluation of the pharmacokinetics of SC144 reveals that intraperitoneal administration of SC144 shows a two-compartmental pharmacokinetics elimination profile that is not observed in the oral dosing.
