Ellipticine cytotoxicity to cancer cell lines - a comparative study. Stiborova M, et al. Interdiscip Toxicol. 2011 Jun;4(2):98-105. PMID: 21753906.
Effects of ellipticine on ALDH1A1-expressing breast cancer stem cells--an in vitro and in silico study. Pandrangi SL, et al. Tumour Biol. 2014 Jan;35(1):723-37. PMID: 23982874.
方法
Cells in exponential growth were seeded at 1×104 per well in a 96-well microplate. After incubation (48 hours) at 37 °C in 5% CO2
saturated atmosphere the MTT solution (2 mg/ml PBS) was added, the microplates were incubated for 4 hours and cells lysed in 50%
a background. The viability of control cells was taken as 100% and the values of treated cells were calculated as a percentage of
control. The IC50 values were calculated from at least 3 independent experiments using linear regression of the dose-log response
N,N-dimethylformamide containing 20% of sodium dodecyl sulfate (SDS), pH 4.5. The absorbance at 570 nm was measured for each
well by multiwell ELISA reader Versamax (Molecular devices, CA, USA). The mean absorbance of medium controls was subtracted as

生物活性
Ellipticine是一种DNA拓扑异构酶II抑制剂。Ellipticine玫瑰树碱作用的另一种方式是通过其与细胞色素P450(CYP)和过氧化物酶的氧化介导的共价DNA加合物的形 成。Ellipticine还可以作为生物转化酶的抑制剂或诱导剂,从而调节其自身的代谢,从而产生其遗传毒性和药理作用。
