Thiadiazole and its derivatives have been widely studied due to their broad range of biological effects. Medicines that are antimicrobial, antifungal, anticancer, anti-inflammatory, and anti-malarial have been found to be efficacious. The substituted-1,3,4-thiadiazole nucleus is quite common, and it may be found in a variety of commercially marketed medications. The synthesis of 1,3,4-thiadiazole derivatives has sparked a lot of attention due to their diverse biological effects, such as antibacterial, anticancer, antiviral, and anti-inflammatory. Certain 1,3,4-thiadiazole derivatives were synthesised as a consequence. They are thought to have better antibacterial characteristics. Under acidic conditions, cyclization of identical thiosemicarbazides gave 1,3,4-thiadiazoles with isomeric pyridyl. Based on the screening results, the final compounds EEE1, EEE2, EEE3, and EEE4 have been identified. A excellent zone of inhibition against gramme positive and gramme negative bacteria using conventional antibiotics.
