We present here the synthesis and antidepressant-like action of a series of 2,5-disubstituted-3-(organoseleno)-selenophenes prepared by a novel synthetic route, the FeCl3âdiorganyl dichalcogenide-mediated intramolecular cyclization of (Z)-chalcogenoenynes. The cyclized products were obtained in good yields. The results showed that 2c, 2d, 2e and 2o, evaluated in the mouse forced-swimming test, elicited an antidepressant-like activity. The studies clearly show that the phenyl group at the 2-position and an organoselenium group at the 3-position of the selenophene ring are essential for the antidepressant-like activity of selenophenes. A close inspection of the results also revealed that the fluorophenyl portion in the organoselenium group is fundamental for the antidepressant-like action of this class of organochalcogens.
我们在此介绍了一系列 2,5-二取代-3-(有机硒)-硒苯的合成和抗抑郁样作用,这些硒苯是通过一种新的合成路线,即 FeCl3âdiorganyl dichalcogenide-mediated intramolecular cyclization of (Z)-chalcogenoenynes 制备的。环化产物的收率很高。结果表明,在小鼠强迫游泳试验中评估的 2c、2d、2e 和 2o 具有类似抗抑郁的活性。这些研究清楚地表明,硒吩环 2 位上的苯基和 3 位上的有机硒基团是硒吩类抗抑郁活性的关键。仔细观察研究结果还发现,有机硒基团中的氟苯基部分是这类有机致癌物抗抑郁作用的基础。
