title: Production, isolation, and preliminary toxicity studies of brevianamide A from cultures of Penicillium viridicatum.
abstract: Brevianamide A, one of a novel group of alkaloids first obtained from Penicillium brevi-compactum, has also been isolated as a principal metabolite from two key isolates of P. viridicatum. Procedures for bioproduction and purification are described. This compound was not toxic when fed or injected into mice and had no antibiotic properties against several common bacterial and fungal microorganisms. Brevianamides A and B are among at least four yellow metabolites that may be formed by isolates of P. viridicatum.
