SRS-A antagonist pyranoquinolone alkaloids from east African Fagara plants and their synthesis

Bioorg Med Chem. 1996 Aug;4(8):1317-20. doi: 10.1016/0968-0896(96)00110-1.

Abstract

Three pyranoquinolone alkaloids isolated from two East African Fagara plants have been found to exhibit SRS-A antagonist action. Their synthesis has been accomplished, using a modified Coppola's method or a thermal cyclization followed by an electrocyclic ring closure.
