cinnamoylated chloroquine hybrid analogues were synthesized and evaluated as antimalarial agents. The trans cinnamic acid derivatives (3-8) were synthesized by utilizing substituted aldehydes and malanoic acid in DMF catalysed by DABCO. The final cinnamoylated chloroquine analogues (9-14) were synthesized by utilizing DCC coupling reagent. The amido chloroquine (17) was prepared from acid (16) and compound 2 in
合成了一系列新的肉桂酰氯喹杂合类似物,并将其评估为抗疟剂。在DABCO催化的DMF中,利用取代的醛和丙二酸合成了反式肉桂酸衍生物(3-8)。利用DCC偶联剂合成了最终的肉桂酰化氯喹类似物(9-14)。使用SOCl2作为氯化剂,由酸(16)和化合物2在苯中制备酰胺基氯喹(17)。在K2CO3作为碱存在下,由2-羟基苯乙酮和2-溴乙酸酯在乙腈中制备相应的酯(15)。酰胺基氯喹-查耳酮类似物(18-22)的制备,是通过酰胺基氯喹(17)和醛在10%的水溶液中的混合得到的。室温下在甲醇中的KOH。此外,我们通过使环氧化物(24a,24b和24c)与2和甲烯二氧基苯胺反应,制备了基于环氧氯丙烷的氯喹-查尔酮类似物(25-28)。使用VERO细胞系进行了对恶性疟原虫的氯喹敏感菌株3D7,耐氯喹菌株K1的体外抗疟活性和化合物的体外细胞毒性。合成的分子显示出显着的体外抗疟活性,尤其是针对CQ抗性菌株(K1
