Abstract

Abstract Nonsymmetrical aldehyde derivatives of gossypol, a yellow polyphenolic pigment of cottonseed, were synthesized by reactions with ammonia, aniline, 4-aminoantipyrine, and barbituric acid. Their structures were determined by UV spectrophotometry and IR and 1 H NMR spectroscopy methods. Their acute toxicities in white mice were compared with those of gossypol and the corresponding symmetrical analogues. It was demonstrated that in ...
