8CR0 - PubMed Abstract:
Benzoxaborole is currently a scaffold of great relevance in medicinal chemistry. In 2016, it was reported to be a new and valuable chemotype for designing carbonic anhydrase (CA) inhibitors. Herein, using an in silico design, we report the synthesis and characterization of substituted 6-(1 H -1,2,3-triazol-1-yl)benzoxaboroles. 6-Azidobenzoxaborole was described for the first time as a molecular platform to prepare libraries of inhibitors by a copper(I)-catalyzed azide-alkyne cycloaddition via a click chemistry strategy. With inhibition constants below 30 nM, some derivatives, such as compound 20 , showed efficacy as selective hCA VII and IX inhibitors. The design hypothesis was validated by crystallographic investigation on the hCA II/ 20 adduct, which provided explanations over the different inhibition behavior observed against the five evaluated hCA isoforms. Overall, this study identified 20 as a new promising lead compound to develop novel anticancer agents targeting the tumor-associated hCA IX but also potent neuropathic pain relievers targeting hCA VII.
