many recognized biological activities, including antiparasitic activity. Although a lot of chalcones have been synthetized and assayed against parasites, the number of structural features known to be involved in this biological property is small. Thus, in the present study, 21 chalcones were synthesized to determine the effect of substituents in the A and B rings on the activity against Leishmania braziliensis
查耳酮是一组天然产物,具有许多公认的生物活性,包括抗寄生虫活性。尽管已经合成了许多查耳酮并对其进行了抗寄生虫分析,但已知与这种生物学特性有关的结构特征的数量很少。因此,在本研究中,合成了 21 种查耳酮,以确定 A 和 B 环中的取代基对巴西利什曼原虫、克氏锥虫和恶性疟原虫的活性的影响。这些化合物以结构依赖的方式对巴西乳杆菌有活性。只有一种化合物对 T. cruzi 非常有效,但没有一种化合物具有显着的抗疟原虫活性。B环中的给电子取代基和C-2'与羰基的氢键影响抗寄生虫活性。
