A thin-layer of (E)-N′-methoxybenzylidenebenzenesulfonohydrazide (MBBSH) was fabricated by the deposition of MBBSH onto a smooth glassy carbon electrode with nafion binder for the sensitive and selective Ga3+ sensor probe.
Background: Chagas disease is a public health problem caused by Trypanosoma cruzi.
Cruzain is a pharmacological target for designing a new drug against this parasite. Hydrazone and Nacylhydrazone
derivatives have been traditionally associated as potential Cruzain inhibitors. Additionally,
benzenesulfonyl derivatives show trypanocidal activity. Therefore, in this study, the combination
of both structures has been taken into account for drug design.
Methods: Seven benzenesulfonylhydrazone (BS-H) and seven N-propionyl benzenesulfonylhydrazone
(BS-NAH) derivatives were synthetized and elucidated by infrared spectroscopy, nuclear magnetic
resonance, and elemental analysis. All compounds were evaluated biologically in vitro against
two strains of Trypanosoma cruzi (NINOA and INC-5), which are endemic in Mexico, and compared
with the reference drugs nifurtimox and benznidazole. In order to gain insight into the putative molecular
origin of the trypanocidal properties of these derivatives, docking studies were carried out
with Cruzain.
Results: Compounds 4 and 6 (BS-H) and 10, 12-14 (BS-NAH) showed the best biological activity
against NINOA and INC-5 strains, respectively. Compound 13 was the most potent trypanocidal
compound showing a LC50 of 0.06 µM against INC-5 strain. However, compound 4 showed the best
activity against both strains (LC50
