MIF-IN-5 (compound 1d) is a highly effective and reversible competitive inhibitor of macrophagemigrationinhibitoryfactor (MIF), exhibiting an IC 50 of 4.8 μM and a Ki value of 3.3 μM [1].
MIF-IN-6 (compound 2d) is an effective inhibitor of macrophagemigrationinhibitoryfactor (MIF), exhibiting an IC50 of 1.4 μM and a Ki value of 0.96 μM. MIF-IN-6 effectively reduces MIF-induced ERK phosphorylation and impedes A549 cell proliferation [1].
