Zn2+/MCM-41 catalyzed Biginelli reaction of heteroaryl aldehydes and evaluation of the antimicrobial activity and cytotoxicity of the pyrimidone products
摘要:
The three component Biginelli condensation of various aryl aldehydes, 1,3-dicarbonyls and urea was investigated in the presence of free or MCM-41 supported ZnNO3. The pyrimidone products, which were obtained under solvent-free conditions, were evaluated for antibacterial and antifungal activities as well as their cytotoxicities. (C) 2015 Elsevier Ltd.

We describe the discovery and optimization of 3,4-dihydropyrimidin-2(1H)-ones as a novel family of (nonzanthine) A(2B) receptor antagonists that exhibit an unusually high selectivity profile. The Biginelli-based hit optimization process enabled a thoughtful exploration of the structure-activity and structure-selectivity relationships for this chemotype, enabling the identification of ligands that combine structural simplicity with excellent hA(2B) AdoR affinity and remarkable selectivity profiles.
