Pharmacological evaluation of newly synthesized organotin IV complex for antiulcer potential

BMC Pharmacology and Toxicology, 2022
AbstractThe present study aims to investigate the newly synthesized organotin (IV) complex (2E, 2′E) dibutylstannanediyl bis (4-(4-nitrophenyl) amino)-4-oxobut-2-enoate (DTN) for its anti-ulcer potential. Characterization performed by carbon nuclear magnetic resonance spectroscopy proved that all values are in the expected ranges of the new compound ...
