A series of seventeen analogs (1─17) were synthesized and characterized through different spectroscopic techniques such as 1H, 13CNMR, HR-EI-MS and were evaluated for in vitro thymidine phosphorylase inhibition. All compounds showed excellent to good thymidine phosphorylase activity having IC50 value ranging between 4.10 ± 0.20 and 54.60 ± 1.40?μM when compared with standard drug 7-deazaxanthine (IC50 = 38.68 ± 1.12?μM). Among the series, compounds 1 (IC50 = 8.30 ± 0.30?μM), 6 (IC50 = 6.30 ± 0.10?μM), 11 (IC50 = 8.40 ± 0.30?μM) and 16 (IC50 = 4.10 ± 0.20?μM) were found more potent. Potent compounds were further subjected to molecular docking study to identify their interactions with the active site of amino acid. Structure activity relationship was done for all analogs mostly based on substitution pattern on phenyl and isatin rings. Graphic abstract: [Figure not available: see fulltext.]

The discovery of antibiotics around the middle twentieth century led to a decrease in the interest in antimycobacterial fatty acids. In order to re-establish the importance of naturally abundant fatty acid, a series of fatty acid-thiadiazole derivatives were designed and synthesized based on molecular hybridization approach. In vitro antimycobacterial potential was established by a screening of synthesized compounds against Mycobacterium tuberculosis H37Rv strain. Among them, compounds 5a, 5d, 5h, and 5j were the most active, with compound 5j exhibiting minimum inhibitory concentration of 2.34?μg/ml against M.tb H37Rv. Additionally, the compounds were docked to determine the probable binding interactions and understand the mechanism of action of most active molecules on enoyl-acyl carrier protein reductases (InhA), which is involved in the mycobacterium fatty acid biosynthetic pathway.

α-Glucosidase is a catabolic enzyme that regulates the body's plasma glucose levels by providing energy sources to maintain healthy functioning. 2-Amino-thiadiazole (1–13) and 2-amino-thiadiazole based Schiff bases (14–22) were synthesized, characterized by 1H NMR and HREI-MS and screened for α-glucosidase inhibitory activity. All twenty-two (22) analogs exhibit varied degree of α-glucosidase inhibitory potential with IC50 values ranging between 2.30 ± 0.1 to 38.30 ± 0.7 μM, when compare with standard drug acarbose having IC50 value of 39.60 ± 0.70 μM. Among the series eight derivatives 1, 2, 6, 7, 14, 17, 19 and 20 showed outstanding α-glucosidase inhibitory potential with IC50 values of 3.30 ± 0.1, 5.80 ± 0.2, 2.30 ± 0.1, 2.70 ± 0.1, 2.30 ± 0.1, 5.50 ± 0.1, 4.70 ± 0.2, and 5.50 ± 0.2 μM respectively, which is many fold better than the standard drug acarbose. The remaining analogs showed good to excellent α-glucosidase inhibition. Structure activity relationship has been established for all compounds. The binding interactions of these compounds were confirmed through molecular docking.
