耗材描述
Mitoxantrone diacetate
产品活性:Mitoxantrone diacetate 是一种有效的拓扑异构酶II (topoisomerase II) 抑制剂。Mitoxantrone diacetate 也可抑制蛋白激酶 C (PKC),其 IC50 值为 8.5 μM。Mitoxantrone diacetate 诱导 B- 慢性淋巴细胞白血病 (B-CLL) 细胞凋亡 (apoptosis)。Mitoxantrone diacetate 具有抗肿瘤活性。Mitoxantrone diacetate 还具有抗正痘病毒 (orthopoxvirus) 活性,对牛痘和猴痘的 EC50 分别为 0.25 μM 和 0.8 μM。

作用靶点:Topoisomerase | PKC | Orthopoxvirus | Apoptosis | Endogenous Metabolite
结构分类:醌类 | 蒽醌类 | 结构分类
In Vitro: Mitoxantrone diacetate inhibits PKC in a competitive manner with respect to histone H1, and its Ki value is 6.3 μM and in a non-competitive manner with respect to phosphatidylserine and ATP.
Mitoxantrone diacetate (0.5 μg/mL, 48 h) induces a decrease in B-CLL cells. Mitoxantrone diacetate induces DNA fragmentation and the proteolytic cleavage of poly(ADP-ribose) polymerase (PARP), demonstrating that the cytotoxic effect of Mitoxantrone diacetate is due to induction of apoptosis.
Mitoxantrone diacetate shows cytotoxicity to human breast carcinoma cell lines MDA-MB-231 and MCF-7 with IC50 values of 18 and 196 nM, respectively.
In Vivo: Mitoxantrone diacetate (IP, 0-3.2 mg/kg/day) produces a statistically significant number of 60-day survivors at 1.6 mg/kg in mice with IP implanted L1210 leukemia.
Mitoxantrone diacetate (IV, 0-3.2 mg/kg/day) shows effective antitumor activities and produces a 60% ILS (increase in lifespan) at 3.2 mg/kg in SC implanted Lewis lung carcinoma.
