The most fungitoxic compound in this study was threo-ethyl 2-bromo-3-fluorosuccinate (C. albicans, 14 mug/ml; A. niger, 30 mug/ml; M. mucedo, 9 mug/ml; T. mentagrophytes, 5 mug/ml). Due to the ease of dehydrohalogenation, the fungitoxicity of 2-bromo-3-fluorosuccinic acid esters may be the result of a mixture composed of the parent compound, the bromo- and fluorofumaric acid esters, and HF and HBr
测试了在不存在pH值5.7和7.0的条件下,对12-溴-和2-2-溴-3-氟代琥珀酸和邻氨基苯甲酸琥珀酸酯(C1-C6)的抗白色念珠菌,黑曲霉,Mucor mucedo和毛癣菌的抗真菌活性。 Sabouraud葡萄糖琼脂中含有10%的牛肉血清。在pH 7.0下,存在10%的牛肉血清时,未观察到赤型和苏型-2-溴-3-氟代琥珀酸酯的真菌毒性的一致规律。增加酯官能团的长度会如下影响真菌毒性:C2大于C1大于C3大于C4大于C5大于C6。在这项研究中,对真菌毒性最大的化合物是2-溴-3-氟丁二酸苏-乙基(白色念珠菌,14杯/毫升;黑曲霉,30杯/毫升; M. mucedo,9杯/毫升;薄荷草, 5杯/毫升)。由于易于脱卤化氢,
