Research Abstract

Screening for inhibitors of NADH-fumarate reductase was conducted using about 8,200 samples of cultured broths of fungi, actinomycetes and bacteria. About 2% of the broths inhibited the enzyme. Active components containing in most of the hit samples were hydrophillic. Fumaric acid or small organic compounds or inorganic salts showed the inhibitory activity was suggested. On the other hand, two hydrophobic active compounds were found in the hit samples. One was (4E)-5-(2-methylphenyl)-4-pentenoic acid from a broth of Streptomyces sp. This was the first NADH-fumarate reductase inhibitor produced by actinomycetes. Anothers were pentaene compounds, prugosene A1 and two new analogs isolated from cultured broth of Penicillium sp FKI-5329. They showed strong inhibitory activity against NADH-fumarate reductase.
