  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.

  A series of 7‐(2‐oxoalkoxy)coumarins have been synthesized by conjugating substituted 7‐hydroxycoumarins with different chloroketones. The anti‐inflammatory properties of 7‐(2‐oxoalkoxy)coumarins were studied in LPS‐induced inflammatory response in J774 macrophages. Western blot was used to determine the expression of iNOS and COX‐2, NO was determined by measuring its metabolite nitrite by Griess reaction

  通过将取代的7-羟基香豆素与不同的氯酮缀合，可以合成一系列7-（2-氧代烷氧基）香豆素。在L774诱导的J774巨噬细胞的炎症反应中研究了7-（2-氧代烷氧基）香豆素的抗炎特性。用Western印迹法测定iNOS和COX-2的表达，通过Griess反应测定其代谢产物亚硝酸盐测定NO，通过ELISA测定IL-6。在100μM的浓度下，有17种被研究的化合物抑制NO和IL-6的产生超过50％。最佳抑制剂的IC 50值对于化合物12为21μM/ 24μM（NO / IL-6），对于化合物20为30μM/ 10μM（NO / IL-6）。主要结果是，被7-（2-氧代烷氧基）取代可改善大多数研究的7-羟基香豆素的抗炎特性。

  In refluxing water and without an additional catalyst, electron-rich phenols could react with alkynoic acids or alkynoates to provide coumarin structures. The skeletons of two natural pyranocoumarins, 5-methoxyseselin and alloxanthoxyletin, could be constructed (total yield up to 76%) in an aqueous multicomponent reaction in which isoprenyl acetate, propiolic acid, and phloroglucinol were simply mixed

  日期：1987.3

  A number of new methyl derivatives of pyranocoumarins, related to 8-desmethylxanthyletine and to 8-desmethylseseline, were synthesized. The syntheses were performed by cyclization in boiling N,N-diethyl aniline of the propargyl or methylpropargyl ethers of the appropriate methyl derivatives of 7-hydroxycou-marin. Methyl groups have been introduced into positions which look most promising for enhancement

  (+)-cis-khellactone derivatives as novel anti-HIV agents, 24 monosubstituted 3', 4'-di-O-(S)-camphanoyl-(+)-cis-khellactone (DCK) derivatives were synthesized asymmetrically. These compounds included 4 isomeric monomethoxy analogues (3-6), 4 isomeric monomethyl analogues (7-10), 4 4-alkyl/aryl-substituted analogues (11-14), and 12 4-methyl-(+)-cis-khellactone derivatives (15-26) with varying 3', 4'-substituents
