synthesized for a structure–activity relationship (SAR) investigation to assess the changes in antimalarial activity which result from 6-aryloxy structural variation, substituent modification on the pyrazine ring, and optimization of the side chain ester group. This SAR study discovered highly potent 6-(2-(alkoxycarbonyl)pyrazinyl-5-oxy)-1,3-dihydro-1-hydroxy-2,1-benzoxaboroles (9, 27–34) with IC50s
设计并合成了一系列6-杂芳氧基苯并x硼烷化合物,用于结构-活性关系(SAR)研究,以评估由6-芳氧基结构变化,吡嗪环上的取代基修饰和侧链优化导致的抗疟疾活性变化链酯基。此SAR研究发现高度有效的6-(2-(烷氧基羰基)吡嗪基-5-氧基)-1,3-二氢-1-羟基-2,1- benzoxaboroles(9,27 - 34)与IC 50 S = 0.2〜针对培养的恶性疟原虫W2和3D7菌株为22 nM 。化合物9在感染的小鼠中也显示出优异的抗伯氏疟原虫的体内功效(ED 90 = 7.0 mg / kg)。
