Thymidine phosphorylase triggers the phosphorylation of pyrimidine base to thymine and 2-deoxyribose 1-phosphate which undergoes dephosphorylation to 2-deoxyribose. It plays a role in tumor angiogenesis which is referred to the development of blood vessels during tumor growth and therefore is an attractive drug target. Keeping in view the greater importance of its inhibition, here in this study we have synthesized piperazine analogs (1-18) and evaluated for thymidine phosphorylase inhibitory activity. All analogs showed potent inhibitory potential with IC values ranging between 0.2 ± 0.01 and 42.20 ± 0.70 µM when compared with standard 7-Deazaxanthine (IC value of 38.68 ± 1.12 µM). Structure activity relationship has been also established for all newly synthesized compounds. Molecular docking studies revealed that these compounds established stronger hydrogen bonding networks with active site residues of enzyme.

Antineoplastic drugs are becoming prevalent due to increasing cancer casualties around the globe. However, the adverse effects of these drugs are evident due to limited insight into the underlying mechanisms that result in non-specific binding and consequent off-target toxicity. The study investigates the side effects of an antineoplastic drug, Capecitabine, a prodrug converted into fluorouracil by Thymidine Phosphorylase (TP) and degrades the RNA of cancerous cells.

This work is based on the synthesis of new ether derivatives bearing benzothiazole (BTA) scaffold through multistep reaction process. Initially, BTA was prepared by refluxing 4-hydroxybenzaldehyde with aminothiophenol having sodium metabisulfite in dimethylformamide (DMF); subsequently, the product was further refluxed with different substituted benzyl and alkyl bromides in acetone to get ether hybrids of BTA in good yields. Structurally, these compounds were confirmed by means of H, C-NMR, and mass spectrometry and evaluated for in vitro thymidine phosphorylase (TP) inhibitory activity.

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.
