General description

Luotonin B is a heteroaromatic pyrroloquinazolinoquinoline alkaloid that, along with Luotonin A and E, was originally isolated from the Chinese medicinal plant Paganum nigellastrum. It is an oxidation product of Luotonin A and is converted to Luotonin E by methanol treatment.

Biochem/physiol Actions

Luotonin compounds have antitumor activity and demonstrate cytotoxicity and inhibitory activity against human topoisomerase. For use as a topoisomerase inhibitor, a starting concentration of 25 μM is suggested. It is suggested that a dose-response curve be performed to find the inhibitor concentration most suitable for the intended assay.

Preparation Note

Solubility is tested at 2 mg/mL in 4:1 solution of choloform and methanol. Solubility of luotonins in DMSO has been reported.
