MMI-0100 is a cell-permeant peptide inhibitor of mitogen activated protein kinase activated protein kinase II (MK2). MMI-0100 reduces intimal hyperplasia ex vivo and in vivo. MMI-0100 suppresses IL-6 expression without effect on IL-8 expression. MMI-0100 suppresses fibrotic processes such as vein graft disease[1].
Naphthofluorescein (compound 19) (0-10 μM; 24 hours) suppresses the HIF-1 reporter activity in a concentration-dependent manner. [1].MMI-0100 (0.25 and 0.5 mM; 24 hours) slightly increases cell proliferation in both cell types compared to control cells treated with 20 ng/ml TNF-α alone[1].MMI-0100 (1 mM) treatment also increases both EC (11%) and SMC (7%) proliferation as compared to control, this response is not as robust as that induced by treatment with 0.5 mM MMI-0100[1].MMI-0100 does not induce EC apoptosis at any dose[1].
MMI-0100 (100 μM; 28 days) inhibits intimal hyperplasia in a mouse vein graft model[1].
