A series of 2-(alpha-hydroxyacetyl)pyridine thiosemicarbazones was synthesized as potential antimalarial and antibacterial agents. Their synthesis was achieved by the condensation of N4-mono- or N4,N4-disubstituted thiosemicarbazides with 2-(alpha-hydroxyacetyl)pyridine. The latter was prepared by selective bromine oxidation of (2-pyridinyl)-1,2-ethanediol. The new compounds show potent inhibitory
合成了一系列的2-(α-羟基乙酰基)吡啶硫代氨基甲唑酮作为潜在的抗疟和抗菌剂。它们的合成通过N4-单-或N4,N4-二取代的硫代氨基脲与2-(α-羟基乙酰基)吡啶的缩合而实现。后者通过选择性溴氧化(2-吡啶基)-1,2-乙二醇来制备。新化合物对青霉素敏感和耐青霉素的淋病奈瑟菌(MIC,0.5-0.004微克/ mL),脑膜炎奈瑟菌(MIC,0.5-0.032微克/ mL)和金黄色葡萄球菌(MIC, 0.5-2毫克/毫升)。在这些新药中,大多数对恶性疟原虫(史密斯菌株; ID50,6.7-38 ng / mL)具有良好的体外抗疟作用,但是12种化合物中只有3种对伯氏疟原虫表现出中等的体内活性。与相应的2-乙酰基吡啶硫代半氨基甲酮相比,这些新剂对宿主的毒性较小,水溶性更高。
