Structure–activity relationships of antitubercular salicylanilides consistent with disruption of the proton gradient via proton shuttling
摘要:
A series of salicylanilides was synthesized based on a high-throughput screening hit against Mycobacterium tuberculosis. A free phenolic hydroxyl on the salicylic acid moeity is required for activity, and the structure-activity relationship of the aniline ring is largely driven by the presence of electron withdrawing groups. We synthesized 94 analogs exploring substitutions of both rings and the linker region in this series and we have identified multiple compounds with low micromolar potency. Unfortunately, cytotoxicity in a murine macrophage cell line trends with antimicrobial activity, suggesting a similar mechanism of action. We propose that salicylanilides function as proton shuttles that kill cells by destroying the cellular proton gradient, limiting their utility as potential therapeutics. Published by Elsevier Ltd.

Disclosed is a method for treating water, including the extraction of at least two ionic species, the ionic species including an anionic species and a cationic species and being present in the water to be treated, the method especially including a step of mixing a liquid hydrophobic organic phase and the water to be treated, the water to be treated being in the liquid state, in order to subsequently obtain liquid treated water and a hydrophobic liquid organic phase loaded with the ionic species, and a step of thermal regeneration of the organic phase loaded with chemical species. Also disclosed are compounds and compositions that can be used in the method.
