MCE 站: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。
研究领域:Cell Cycle/DNA Damage | Epigenetics | TGF-beta/Smad | Apoptosis | Metabolic Enzyme/Protease
作用靶点:Topoisomerase | PKC | Apoptosis | Endogenous Metabolite
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, 1.6 mg/kg/day; as a free base) produces a statistically significant number of 60-day survivors (curative effect) in mice with IP implanted L1210 leukemia.
In SC implanted Lewis lung carcinoma, Mitoxantrone diacetate and ADM administered IV also shows effective antitumor activities and produces a 60% and a 45% ILS, respectively.
