In pursuit of effective thymidine phosphorylase inhibitors, a series of hybrid analogs of thiazole-hydrazone derivatives (1-15) were synthesized and evaluated for their enzyme inhibitory potential using 7-deazaxanthine as a positive control. The goal was to determine these derivatives' effectiveness in suppressing thymidine phosphorylase activity, a target relevant to antitumor strategies due to the enzyme's role in angiogenesis and tumor growth. Biological evaluations indicated that all synthesized analogs displayed significant to moderate inhibitory activity, with IC values between 3.

Diabetes mellitus (DM) is a disorder which is raised at the alarming level and it is characterized by the hyperglycemia results from the impaired action of insulin, production of insulin or both of these simultaneously. Consequently, it causes problems or failure of different body organs such as kidneys, heart, eyes, nerve system. Since this disease cannot be completely cured until now, we aimed to design series of enzymes inhibitors and tested them for DM treatment.

In this study, NiSe nanocubes, ZnO rods, and their composites were prepared by simple chemical methods to investigate their photocatalytic response and antibacterial activity. The optimal concentration of NiSe nanocubes was explored for enhanced photocatalytic performance by varying its percentage in the NiSe-ZnO composites. The findings suggested that the optical response of ZnO was significantly improved and shifted towards visible region by incorporating NiSe as a co-catalyst.
