The synthesis and the photobiological activity of new tetrahydrobenzo- and benzofurobenzopyrone derivatives carrying at position 4 of benzopyrone ring of furobenzopyrone moiety a phenyl, or a methyl group with a linear structure or with various angular arrangements, are reported. The new compounds are characterized by having an additional cyclohexene or phenyl ring condensed at the 2, 3 double bond
报道了在呋喃苯并吡喃酮部分的苯并吡喃酮环的4位带有苯基或具有直链结构或具有各种角度排列的甲基的新的四氢苯并-和苯并呋喃苯并吡喃酮衍生物的合成和光生物活性。新化合物的特征是在呋喃苯并吡喃核的呋喃环的2,3双键上有一个额外的环己烯或苯环。合成是从适当的羟基苯并吡喃酮开始进行的,在羟基苯并吡喃酮上建立了四氢苯并呋喃或苯并呋喃部分,这看起来最有希望增强化合物对DNA的光反应性。筛选所有合成的化合物的光敏活性,其中一些表现出良好的活性,在黑暗中也观察到一定的作用。
