Intoplicine (RP 60475), an antitumor derivative in the 7H-benzo[e]pyrido[4,3-b]indole series, is a DNA topoisomerase I and II inhibitor. Intoplicine strongly binds DNA (KA = 2 x 105 /M) and thereby increases the length of linear DNA[1][2].

ChEBI: Intoplicine is a pyridoindole.

Topoisomerase I; Topoisomerase II
