Exploring the Bioactive Landscape of Aryl-Functionalized 1,2,4-Dithiazolidines
Main Article Content
Abstract
Dithiazolidines represent a special and distinctive class of organic compounds characterized by a peculiar heterocyclic ring containing two sulfur and two nitrogen atoms with a specific arrangement. Introduction of different substituents or functional groups alters their chemical behavior and reactivity which makes them valuable in diverse fields such as organic synthesis, medicinal chemistry, materials science, and coordination chemistry. Due to to their unique structural features as well as mechanism of action, various derivatives of dithiazolidines have attracted attention for their potential antimicrobial activities. In this study, aryl isothiocyanates produces N aryl S chloro isothiocarbamoyl chloride by reacting with p-phenylenediamine by reflux in chloroform. This intermediate compound on chlorination which subsequently followed by cyclization, forms 3,5 diaryl, diimino, 4 (aryl amino) 1,2,4 dithiazolidines. The synthesized compounds containing different substituents were characterized using infrared (IR), nuclear magnetic resonance (NMR), and mass spectroscopic techniques. Biological screening for antibacterial and antifungal activity against selected microbial strains was done which revealed that these newly synthesized derivatives exhibited moderate to significant activity. Furthermore, molecular docking studies were also performed to investigate the binding interactions of these newly synthesized dithiazolidines derivatives with target proteins. The molecular docking results showed good agreement with the experimental findings. This reinforces the potential of these compounds as a promising scaffold for antimicrobial drug development. Overall, this work highlights the promising use of dithiazolidine derivatives in medicinal chemistry and encourages further exploration of their applications
