MK2-IN-3 is a potent and selective inhibitor of MAPKAP-K2 (MK-2), with an IC50 of 8.5 nM. MK2-IN-3 shows selectivity for MK-2 over MK-3, MK-5, ERK2, MNK1, p38a (IC50s=0.21, 0.081, 3.44, 5.7, and >100 μM, respectively) and MSK1, MSK2, CDK2, JNK2, IKK2 (IC50s>200 μM). MK2-IN-3 can reduce TNFα production in both U937 cells and in vivo.

Description

MK2-IN-3 is a potent and selective inhibitor of MAPKAP-K2 (MK-2), with an IC50 of 8.5 nM. MK2-IN-3 shows selectivity for MK-2 over MK-3, MK-5, ERK2, MNK1, p38a (IC50s=0.21, 0.081, 3.44, 5.7, and >100 μM, respectively) and MSK1, MSK2, CDK2, JNK2, IKK2 (IC50s>200 μM). MK2-IN-3 can reduce TNFα production in both U937 cells and in vivo[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
