货号:A537376 同义名: 依沙替康甲磺酸盐 / DX8951f;Exatecan (mesylate)

Exatecan mesylate is a totally synthetic analogue of the topoisomerase I-inhibitor camptothecin, which was synthesised to impart increased aqueous solubility, greater tumour efficacy, and less toxicity than camptothecin itself.

Exatecan mesylate 生物活性

描述 DNA topoisomerases are enzymes that catalyze the alteration of DNA topology with transiently induced DNA strand breakage, essential for DNA replication[3]. Exatecan mesylate is a totally synthetic analogue of the topoisomerase I-inhibitor camptothecin, which was synthesised to impart increased aqueous solubility, greater tumour efficacy, and less toxicity than camptothecin itself. Exatecan mesylate (DX-8951f) significantly inhibits the proliferation of several cancer cell lines, with mean GI50s of 2.02 ng/mL, 2.92 ng/mL, 1.53 ng/mL, and 0.877 ng/mL for breast cancer cells, colon cancer cells, stomach cancer cells and lung cancer cells, respectively[4]. Exatecan mesylate (DX-8951f, 3.325-50 mg/kg, i.v.) exhibits antitumor activities in the mice model bearing tumor cells, without toxic death. Exatecan mesylate (15, 25 mg/kg, i.v.) hightly inhibits MIA-PaCa, BxPC-3 primary tumor growth in the MIA-PaCa-2 early-stage model and early-stage model of BxPC-3. Exatecan mesylate (15, 25 mg/kg, i.v.) also significantly suppresses BxPC-3 lymphatic metastasis and completely eliminates lung metastasis in the BxPC-3 late-stage cancer model[5]. Exatecan mesylate (DX-8951f) displays cytotoxic activities against PC-6, PC-6/SN2-5 cells, with mean GI50s of 0.186 and 0.395 ng/mL, respectively. Exatecan mesylate (34 nM) stabilizes DNA-TopoI complexes in PC-6 and PC-6/SN2-5 cells[6].
