    Spirocyclopropane- and spiroazetidine-substituted tetracycles 13D-E and 16A are described as orally active MK2 inhibitors. The spiroazetidine derivatives are potent MK2 inhibitors with IC(50)<3 nM and inhibit the release of TNFalpha (IC(50)<0.3 microM) from hPBMCs and hsp27 phosphorylation in anisomycin stimulated THP-1 cells. The spirocyclopropane analogues are less potent against MK2 (IC(50)=0.05-0.23 microM), less potent in cells (IC(50)<1.1 microM), but show good oral absorption. Compound 13E (100mg/kg po; bid) showed oral activity in rAIA and mCIA, with significant reduction of swelling and histological score.
