Voreloxin hydrochloride (SNS-595, Vosaroxin)是强效的广谱抗肿瘤活性的Topoisomerase II抑制剂。Phase 2。 产品应用： Voreloxin Hydrochloride 是一种新创的拓扑异构酶 II (topoisomerase II) 抑制剂，能够诱导 DNA 双链断裂，阻滞 G2 期，最终细胞凋亡。 Information Voreloxin hydrochloride (SNS-595, Vosaroxin) is a potentTopoisomerase IIinhibitor with broad-spectrum anti-tumor activity. Phase 2. Targets Topo II In vitro Voreloxin exhibits potent inhibitory effect in topoisomerase II relaxation with IC50 of 3.2 μg /mL without effect on topoisomerase II cleavage. Voreloxin has a cytotoxic activity against human tumor cell lines more potent than that of etoposide. Voreloxin has broad anti-proliferative activity in 15 cell lines, including 4 drug-resistant lines, with IC50 ranging from 0.04 to 1.155 μM. In vivo Voreloxin (50 mg/kg i.p.) shows potent in vivo antitumor activity mice implanted with P388 leukemia cells. Voreloxin (25 mg/kg i.v.) demonstrates strong tumor growth inhibition in 10 of 11 solid tumor (breast, ovarian, colon, lung, gastric, and melanoma) xenograft models, 2 hematologic tumor xenograft models, 3 multidrug resistant tumor models and 3 murine syngeneic tumor models (Colon 26, Lewis Lung carcinoma, M5076 Ovarian Sarcoma).
