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 1H NMR spectroscopy methods. Their acute toxicities in white mice were compared with those of gossypol and the corresponding symmetrical analogues
通过与氨、苯胺、4-氨基安替比林和巴比妥酸反应合成棉酚的非对称醛衍生物,棉籽的黄色多酚色素。它们的结构通过紫外分光光度法和红外和 1 H 核磁共振光谱法确定。将它们在白色小鼠中的急性毒性与棉酚和相应的对称类似物的急性毒性进行了比较。结果表明,一般而言,棉酚衍生物中可用的游离醛基团越少,其急性毒性就越低。只有在带有 4-氨基安替比林残基的非对称棉酚衍生物的情况下,我们才观察到与上述相关性的偏差:其对称对应物的毒性更大,但仍然比棉酚毒性小。
