In this study, two series of cyanopyrimidine hybrids were synthesized and evaluated for their anticancer and anti-inflammatory activities. The results showed that compounds 3b, 5b, and 5d exhibited the highest activity and had desirable properties regarding drug absorption, oral bioavailability, and drug-drug interactions.
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 10.5-fold higher than Nimesulide. Furthermore, the pyrimidine derivatives 3b, 5b, and 5d demonstrated anticancer activity comparable to or better than doxorubicin against four cell lines, i.e., MCF-7, A549, A498, and HepG2, with IC50 values in nanomolar in addition to low cytotoxicity on the normal W38-I cell line. The effect of compound 5d on cell cycle progression and apoptosis induction was investigated, and it was found that compound 5d could seize cell growth at the sub-G1 and G2/M phases, as well as increase the proportion of early and late apoptotic rates in MCF-7 cells by nearly 13- and 60-fold, respectively. Moreover, in silico studies for compounds 3b, 5b, and 5d revealed promising findings, such as strong GIT absorption, absence of BBB permeability, nil-to-low drug-drug interactions, good oral bioavailability, and optimal physicochemical properties, indicating their potential as promising therapeutic candidates.
