Abstract
The synergistic effect of dual inhibition of serine/threonine protein kinases that are involved in the same signalling pathway of the diseases can exert superior biological benefits for treatment of these diseases. In the present work, a new series of (imidazol-5-yl)pyrimidine was designed and synthesized as dual inhibitors of BRAFV600E and p38α kinases which are considered as key regulators in mitogen-activated protein kinase (MAPK) signalling pathway. The target compounds were evaluated for dual kinase inhibitory activity. The tested compounds exhibited nanomolar scale IC50 values against BRAFV600E and low to sub-micromolar IC50 range against p38α. Compound 20h was identified as the most potent dual BRAFV600E/p38α inhibitor with IC50 values of 2.49 and 85 nM, respectively. Further deep investigation revealed that compound 20h possesses inhibitory activity of TNF-α production in lipopolysaccharide-induced RAW 264.7 macrophages with IC50 value of 96.3 nM. Additionally, the target compounds efficiently frustrated the proliferation of LOX-IMVI melanoma cell line. Compound 20h showed a satisfactory antiproliferative activity with IC50 value of 13 μM, while, compound 18f exhibited the highest cytotoxicity potency with IC50 value of 0.9 μM. Compound 18f is 11.11-fold more selective toward LOX-IMVI melanoma cells than IOSE-80PC normal cells. The newly reported compounds represent therapeutically promising candidates for further development of BRAFV600E/p38α inhibitors in an attempt to overcome the acquired resistance of BRAF mutant melanoma.
