New Pyrimidine-5-Carbonitriles as COX-2 Inhibitors: Design, Synthesis, Anticancer Screening, Molecular Docking, and In Silico ADME Profile Studies.

ABSTRACT: Two series of cyanopyrimidine hybrids were synthesized bearing either benzo[d]imidazole, benzo[d]oxazole, benzo[d]thiazole, and benzo[b]thiophene derivatives via methylene amino linker 3a-3d (Formula A) or various sulphonamide phenyl moieties 5a-5d (Formula B) at the C-2 position. All compounds' cyclooxygenase COX-2 inhibitory activities were evaluated, and all synthesized compounds demonstrated potent activity at minimal concentrations, with IC₅₀ values in the submicromolar range. Compounds 3b, 5b, and 5d were discovered to be the most active pyrimidine derivatives, with the highest COX-2 percent inhibition and IC₅₀ values being nearly equal to Celecoxib and approximately 4.7-, 9.3-, and 10.
