A novel 5-HT receptor ligand and related cytotoxic compounds from an acid mine waste extremophile

J Nat Prod. 2003 Aug;66(8):1097-100. doi: 10.1021/np030044w.

Abstract

Berkeley Pit Lake in Butte, Montana, is an acid mine waste reservoir rich in toxic metals. A Pithomycessp. isolated from the Pit Lake yielded three tyrosine derivatives (1-3), one of which acts as a 5-HT((2a)) receptor ligand. This type of activity has been associated with migraine preventative and antihypertensive drugs. The isolation and characterization of compounds 1-3 and three sesquiterpenes (5-7) that have been isolated previously from higher plants are reported here.
