Discovery of 3,4-Dihydropyrimidin-2(1H)-ones As a Novel Class of Potent and Selective A2B Adenosine Receptor Antagonists

Abstract: We describe the discovery and optimization of 3,4-dihydropyrimidin-2(1H)-ones as a novel family of (nonxanthine) A2B 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 hA2B AdoR affinity and remarkable selectivity profiles.

“…DHPMs usually have distinct biological activities and can be applied as calcium channel modulators, adrenergic receptor antagonists, antibacterials, mitotic Kinesin inhibitors, antivirals, and others, as reviewed elsewhere. [25][26][27] Importantly, DHPMs typically have pronounced biological activities in their racemic forms, 28 In this context, the courtship between CPs/MOFs and MCRs has produced promising results which opened up a large but as yet unexploited avenue of possibilities. Some MCRs, for instance, have been recently performed catalysed by CPs/MOF scaffolds with relative successes; 29-31 therefore fostering interest in the development of new stable and more robust hybrid materials capable of performing catalysed MCRs.…”
