Abstract:
:A benzopyranopyridine inhibitor of mitogen-activated protein kinase-activated protein kinase 2 (MK2) is prepared rapidly and efficiently in one step using microwave dielectric heating, whereas a substrate-selective p38 MAPK inhibitor was prepared using conventional heating techniques. The former had MK2 inhibitory activity above 2.5 microM concentration, whereas the latter showed no MK2 inhibition at 10 microM. However, rather than rescuing the reduced cellular growth rate and aged morphology of hTERT-immortalised WS dermal fibroblasts, both induce a state resembling stress-induced cellular senescence, suggesting that these inhibitors may have limited therapeutic use.
