Abstract
Cochliobolic acid (1), a novel biologically active natural product, is produced by submerged fermentation of Cochliobolus lunatus. Compound 1 was determined to be a novel polyketide possessing a substituted tetrahydrofuran ring, a conjugated polyene chain and a 1,2-diketone moiety, by interpretation of NMR, MS, and UV/vis spectroscopic data. Compound 1 inhibits the binding of TGF-alpha to the EGF receptor of the human epidermal cell line A431 in a SPA assay with an IC50 of 1.6 microM.
