“…The synthesis of thiadiazole Schiff bases has also received a lot of interest because it is well-known that Schiff bases containing heterocyclic rings are cytotoxic and that they act against microorganisms and are anti-cancer and anti-fungal, malarial, viral, and bacterial infections. They are also known to be antidepressant enzyme inhibitors (Durmuş et al, 2017), analgesics, anthelmintic, growth regulators of plants (SALIH, 2008), and anti-pyretic (Kapadiya et al, 2020). Some Schiff bases are also utilized in ion sensors and electrochemical sensors to improve the selectivity and sensitivity of detection (Mobinikhaledi et al, 2011).…”

Two new series of various heterocyclic bis-Schiff bases of Thiadiazoles disulfides and thioethers are synthesized. The first series was the synthesis of bis-Schiff of thiadiazole disulfides (4a-h) synthesized from their corresponding Schiff bases after oxidation by hydrogen peroxide. The second series was the synthesis of bis-Schiff base thiadiazole thioethers (7a-h). It was obtained from the reaction of bis-thiadiazole diamine (6) with different aldehyde. The diamine (6) was generated by reacting thiadiazole with dibromoethane in dimethylformamide and triethylamine as a catalyst. All of the synthesized compounds were analyzed by using FT-IR, 1H-NMR, 13C-NMR, and C-APT techniques. The synthesized compounds were screened against two gram-positive bacteria (Staphylococcus and streptococcus), and two strains of gram-negative (E. coli and klebsiella) in comparison to two standard strong antibiotic drugs (ciprofloxacin and vancomycin). Generally, all the synthesized compounds showed highly antibacterial properties, particularly, compounds (4b,4f, and 7b) which observed potent anti-bacterial properties against both gram- (positive, negative) bacteria were even higher than the standard drugs. Lastly, molecular docking studies were also applied to find the binding affinity and active sides of the products with the target proteins.
