Further structure–activity relationship (SAR) studies on the recently identified pyrido[1,2-a]benzimidazole (PBI) antimalarials have led to the identification of potent, metabolically stable compounds with improved in vivo oral efficacy in the P. berghei mouse model and additional activity against parasite liver and gametocyte stages, making them potential candidates for preclinical development.

对最近鉴定出的吡啶并[1,2- a ]苯并咪唑(PBI)抗疟药的进一步结构-活性关系(SAR)研究已导致鉴定出有效的,代谢稳定的化合物,从而在伯氏疟原虫小鼠模型中具有改善的体内口服功效以及针对寄生虫肝脏和配子细胞阶段的额外活性,使其成为临床前开发的潜在候选者。抑制hezozoin的形成可能有助于其作用机理。
