生化/生理作用
Luotonin A is a cytotoxic alkaloid reported to inhibit topoisomerase I. Luotonin A was originally isolated from the Chinese medicinal plant Paganum nigellastrum. As an antitumor agent, Luotonin A demonstrates cytotoxic activity against the mouse leukemic cell line P-388 at low concentrations (IC50 1.8μg/mL). Luotonin A stabilizes the cleavable human topoisomerase I-DNA binary complex resulting in cytotoxicity to cells (IC50 5.07-12.6 μM).Luotonin forms non-covalent complexes with ds-DNA in the minor groove. It may serve as a prototype for analytical probes of DNA hybridization.
重悬
Solubility is tested at 4 mg/mL in 1:1 solution of choloform and methanol. Solubility of luotonins in DMSO has been reported.
