Anstifolines A and B, two dimeric furoquinoline alkaloids from the root bark of Dictamnus angustifolius†
Abstract
Anstifolines A and B, two dimeric furoquinoline alkaloids with unique coupling patterns were isolated from the root bark of Dictamnus angustifolius. The biosynthetic pathway of anstifoline A was proposed. All of the isolates exhibited cytotoxicities and inhibition of superoxide anion generation and elastase release.
