Abstract

A series of 4-Alkyl-5-oxo-N-(pyridin-3-yl)-4,5-dihydro [1,2,3] triazolo[1,5-a] quinazoline-3-carbothioamide compounds ( 8a-8k ) were synthesized as p38 MAP kinase inhibitors, which could potentially be used as anticancer agents. The synthesized compounds were assessed for their effectiveness in inhibiting cancer using the MCF-7 cancer cell line. The results showed that compound 8a had the highest potency, with an IC 50 value of 39.76 ± 0.25 µM. Compound 8f and 8d exhibited noteworthy activity, with IC 50 values of 40.43 ± 2.04 µM and 42.15 ± 2.15 µM, respectively. Compound 8a was found to effectively bind with the active site of p38α MAP kinase, with the PDB ID 1W7H. The docking score was found to be -8.8 kcal/mol. The ADME experiments, following Lipinski's rule of five and Ergan's egg graph, showed that all the synthesized compounds had excellent oral bioavailability and acceptable stomach absorption. Compound 8a stood out as the most potent drug in the series, exhibiting considerable docking affinity, ADME profile, and p38 MAP kinase inhibitory action. The findings indicated that compound 8a has promising p38 kinase inhibition and can be a possible therapeutic drug for further investigation .
