General description
Luotonin E is a heteroaromatic pyrroloquinazolinoquinoline alkaloid that, along with Luotonin A and B, was originally isolated from the Chinese medicinal plant Paganum nigellastrum. 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.
Biochem/physiol Actions
Luotonin E exhibited strong cytotoxic effects specifically on human leukemia P-388 cells. [1]
Reconstitution
Solubility is tested at 4 mg/mL in 4:1 solution of choloform and methanol. Solubility of luotonins in DMSO has been reported.

Luotonins are alkaloids from the aerial parts of Peganum nigellastrum Bunge. that display three major skeleton types. Luotonins A, B, and E are pyrroloquinazolino-quinoline alkaloids, luotonins C and D are canthin-6-one alkaloids, and luotonin F is a 4(3H)-quinazolinone alkaloid. All
