In this work the synthesis and antiparasitical activity of new 1,5-diaryl-3-oxo-1,4-pentadienyl derivatives are described. First, compounds 1a, 1b, 1c and 1d were prepared by acid-catalyzed aldol reaction between 2-butanone and benzaldehyde, anisaldehyde, p-N,N-dimethylaminobenzaldehyde and p-nitrobenzaldehyde. Reacting each of the methyl ketones 1a, 1b, 1c and 1d with the p-substituted benzaldehydes
在这项工作中,描述了新的1,5-二芳基-3-氧代-1,4-戊二烯基衍生物的合成和抗寄生虫活性。首先,化合物1A,1B,1C和1D是由2-丁酮和苯甲醛,茴香醛,间酸催化醛醇缩合反应制备的p - Ñ,Ñ -dimethylaminobenzaldehyde和p -nitrobenzaldehyde。在碱性催化的羟醛反应下,使每个甲基酮1a,1b,1c和1d与对位取代的苯甲醛反应,我们进一步制备了化合物2a –2p。评价所有二十种化合物的抗增殖活性,特别是对亚马逊利什曼原虫的前鞭毛体和克氏锥虫的鞭毛体的抗增殖活性。所有化合物均显示出良好的活性,而硝基化合物2i和2k在数μM下显示出抑制活性。
