Recent synthetic and medicinal perspectives of dihydropyrimidinones: A review

open access: yesEuropean Journal of Medicinal Chemistry, 2017
Dihydropyrimidines are the most important heterocyclic ring systems which play an important role in the synthesis of DNA and RNA. Synthetically they were synthesized using Multi-component reactions like Biginelli reaction and Hantzschdihydropyridine.

Decoding Urease Inhibition: A Comprehensive Review of Inhibitor Scaffolds

open access: yesChemMedChem, Volume 21, Issue 2, January 2026.
Representative functional groups known for urease inhibition are reviewed within diverse scaffolds using structure–activity analyses to identify features associated with high inhibitory activity. Urease is a metalloenzyme produced by a wide range of organisms and plays a critical role in nitrogen microbial metabolism by catalyzing the hydrolysis of ...

Antidiabetic Evaluation of New Pyrimidine‐Thiazoline Hybrids Endorsed With Enzyme Kinetic Studies and Computational Analysis

open access: yesChemical Biology &Drug Design, Volume 106, Issue 6, December 2025.
We demonstrated the application of molecular hybridization in disclosing new pyrimidine‐thiazole molecular hybrids as potential α‐glucosidase and α‐amylase inhibitors and antioxidant agents. The representative compound of the series exhibited 3‐fold more potency than the standard drug acarbose against α‐glucosidase and 2‐fold greater potency than ...
