temperature, was studied. Some of the evaluated compounds showed a remarkable activity as Leishmania mexicana growth inhibitors, obtaining the best results with the acetylated derivatives. The advantages showed by the enzymatic methodology, such as mild reaction conditions and low environmental impact, make the biocatalysis a convenient way to prepare these derivatives of substituted pyridines with application
合成了一系列的2-和3-羟基吡啶的羟烷基和酰氧基烷基衍生物,并评价了它们作为原生动物利什曼原虫的生长抑制剂的生物学活性。通过化学酶学方法在两个反应步骤中获得了三十种新化合物。研究了酶促反应中各种反应参数的影响,如酶的来源,酰化剂/底物的比例,酶/底物的比例,溶剂和温度等。一些被评估的化合物显示出显着的活性,如墨西哥利什曼原虫生长抑制剂,使用乙酰化衍生物可获得最佳效果。酶法所显示的优点,例如温和的反应条件和对环境的低影响,使生物催化成为制备取代吡啶的这些衍生物的便捷方法,并可用作潜在的抗寄生虫剂。
