A series of boron-containing benzoxaborole compounds was designed and synthesized for a structure–activity relationship investigation surrounding 7-(HOOCCH<sub>2</sub>CH<sub>2</sub>)-1,3-dihydro-1-hydroxy-2,1-benzoxaborole (1) with the goal of discovering a new antimalarial treatment. Compound 1 demonstrates the best potency (IC<sub>50</sub> = 26 nM) against Plasmodium falciparum and has good drug-like properties, with low molecular weight (206.00), low ClogP (0.86) and high water solubility (750 µg/ml at pH 7).
