Insight into thymidine phosphorylase and molecular docking studies: identification of hybrid thiazole bearing Schiff base derivatives.

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.

Chitosan-PVA-PVP/nano-clay composite: a promising tool for controlled drug delivery.

In this study, chitosan, polyvinyl alcohol (PVA), and polyvinyl pyrrolidone (PVP) were used to create ternary blends reinforced with organically modified montmorillonite nanoclay. Tramadol was used as a model drug to assess the efficacy of these ternary blends as drug delivery systems. The current work demonstrated the highly controlled release of tramadol transdermal administration.

Design, synthesis, in-vitro, in-vivo and in-silico studies of pyrrolidine-2,5-dione derivatives as multitarget anti-inflammatory agents.

In recent years, drug discovery paradigm has been shifted from conventional single target inhibition toward multitarget design concept. In current research, we have reported synthesis, in-vitro, in-vivo and acute toxicity determination of N-substituted pyrrolidine-2,5-dione derivatives as multitarget anti-inflammatory agents. We synthesized cycloalkyl, alkyl and aryl carbonyl derivatives by the Michael addition of ketones to N-substituted maleimides using self-assembled three component system as an organocatalyst.

Synthesis of functionalized arylpyridines and -pyrimidines by domino [4+2]/retro [4+2] cycloadditions of electron-rich dienes with alkynylpyridines and -pyrimidines.

Aryl-substituted pyridines and pyrimidines were prepared by [4+2] cycloadditions of alkynyl-substituted pyridines and -pyrimidines with electron-rich dienes. The reactions proceed by formation of a bridged cycloadduct and subsequent thermal extrusion of ethylene. The pyridine moiety plays a crucial role for the success of the reaction.
