A new series of O-substituted chalcone derivatives bearing an/a allyl-, prenyl- or propargyl-substituent at different positions of rings A and B and their derivatives as drug leads, was designed, synthesized, and characterized. The chalcone derivatives were synthesized via base catalyzed Claisen-Schmidt condensation in MeOH or EtOH solutions of appropriately substituted aromatic ketones with O-allyl
设计,合成和表征了一系列新的O-取代的查尔酮衍生物,它们在A和B环的不同位置带有一个烯丙基,异戊烯基或炔丙基取代基,并且它们的衍生物作为药物前导物。查尔酮衍生物通过分别在适当取代的芳族酮与O-烯丙基和O-炔丙基香兰素的MeOH或EtOH溶液中进行碱催化Claisen-Schmidt缩合反应合成。中间体O首先通过亲核取代反应合成了取代的苯酮衍生物。所有新合成的化合物都通过IR,NMR光谱数据和元素分析进行了表征。用化合物(1a,1b,2a,2b,3a,3b,4a,5a-f,6a-d,7a-d)和阳性对照阿霉素对CCRF-CEM白血病细胞进行了初步的细胞毒性作用。其中,化合物1a,2a,5b-d,6b,7a,7c阿霉素显示的IC 50值低于20 µM,而其他化合物的活性低或高达50 µM时没有活性。令人惊讶的细胞毒性效应,其中5c对HCT116 p53 -/-结肠腺癌细胞,5e对CCRF-CEM细胞和MDA-MB-231
