Discovery of a Potent Dihydrooxadiazole Series of Non-ATP-Competitive MK2 (MAPKAPK2) Inhibitors.

ABSTRACT: Inhibition of MK2 has been shown to offer advantages over that of p38 MAPK in the development of cures for inflammatory diseases such as arthritis. P38 MAPK knockout in mice was lethal, whereas MK2-null mice demonstrated strong inhibition of disease progression in collagen-induced arthritis and appeared normal and viable. However, it is challenging to develop ATP-competitive MK2 inhibitors due to high ATP binding affinity to the kinase. Non-ATP-competitive MK2 inhibitors interact and bind to the kinase in a mode independent of ATP concentration, which could provide better selectivity and cellular potency. Therefore, it is desirable to identify non-ATP-competitive MK2 inhibitors. Through structure optimization of lead compound 1, a novel series of dihydrooxadiazoles was discovered. Addition
