The chalcone-like series 1a–1g was efficiently synthesized from Morita–Baylis–Hillman reaction (52–74% yields). Compounds 1a–1g were designed by molecular hybridization based on the anti-inflammatory drug methyl salicylate (3) and the antileishmanial moiety of the Morita–Baylis–Hillman adducts 2a–2g. The 1a–1g compounds were much more actives than precursor series 2a–2g, for example, IC50 = 7.65 μM
从Morita-Baylis-Hillman反应(产率52-74%)有效地合成了类似查尔酮的系列1a-1g。化合物1a-1g是根据抗炎药水杨酸甲酯(3)和Morita-Baylis-Hillman加成物2a-2g的抗疟药部分通过分子杂交设计的。在图1A-1G的化合物比前体系列更多的活性物质2A-2G,例如,IC 50 = 7.65μM上利什曼亚马孙和10.14μM上利什曼恰加斯利什(化合物1C)相比,IC 50 = 50.08μM上亚马逊利什曼原虫和在南美锥虫上的82.29μM(化合物2c)。该IC 50化合物的值3(228.49μM上亚马逊利什曼原虫和261.45μM上L.恰加斯利什)和丙烯酰基水杨酸酯4(108.50μM上亚马逊利什曼原虫和118.83μM上L.恰加斯利什)在这里确定的,由第一时间,在利什曼原虫上。
