  Synthesis and Biological Activity of (Hydroxymethyl)- and (Diethylaminomethyl)benzopsoralens

  摘要：

  Some benzopsoralens, carrying a hydroxymethyl or a diethylaminomethyl group at the 3, 5, 8, and 11 positions, were prepared, and their biological activity was compared with that of 4-(hydroxymethyl)benzopsoralen (BP). 5-(Hydroxymethyl)benzopsoralen (7b), 11-(hydroxymethyl)benzopsoralen (7c), and 11-(diethylaminomethyl)benzopsoralen (8c) induced marked antiproliferative effects in mammalian cells by simple incubation in the dark; this activity appeared to be related to their ability to inhibit topoisomerase II. Benzopsoralens appeared to be more active, especially BP and 7c, upon WA activation. Compounds carrying a methyl group at the 4 position together with a hydroxymethyl Or diethylaminomethyl at the 8 position (7d and 8d, respectively) were also effective, although to a lower extent; instead, a substituent at the 3 position canceled all activity. Benzopsoralens did not induce interstrand cross-links in DNA in vitro, as seen in the induction of cytoplasmic <> mutations and double-strand breaks in yeast. This behavior is also compatible with their low mutagenic activity in E. coli WP2 and with the absence of any phototoxicity on the skin. For these features, benzopsoralens seem to be interesting potential drugs for PUVA photochemotherapy and photopheresis. The activity shown in the dark is not sufficient for their possible use as antitumor drugs, but it does offer a new model for the study of topoisomerase inhibitors.

  四氢苯并呋喃香豆素和苯并呋喃香豆素的甲基x衍生物，一类新的潜在的脱氧核糖核酸光试剂

  摘要：

  合成了许多具有线性结构或具有各种角度排列的新的四环呋喃香豆素衍生物。新化合物的特征在于在呋喃香豆素核的呋喃环的4'，5'双键上稠合了一个额外的环己烯或苯环。从合适的羟基香豆素开始进行合成，在该羟基香豆素上建立了四氢苯并呋喃或苯并呋喃部分。甲基被引入到看起来最有希望增强化合物对DNA的光反应性的位置。

  A number of new tetracyclic furocoumarin derivatives with a linear structure or with various angular arrangements, were synthetized. The new compounds are characterized for having an additional cyclohexene or phenyl ring condensed at the 4′,5′ double bond of the furan ring of the furocoumarin nucleus. The syntheses were performed starting from the appropriate hydroxycoumarins on which the tetrahydrobenzofuran
