CC-99677 is a selectively targeted covalent MAPKAPK2 (MK2) inhibitor for autoimmune diseases that translates biochemical potency into cellular potency as demonstrated by potent inhibition of heat shock protein 27 (HSP1) phosphorylation in LPS-activated monocyte THP-27 cells via a nucleophilic aromatic substitution (SNAr) mechanism.CC-99677 in Rat experiments demonstrated potency in both biochemical (IC 50 =156.3 nM) and cellular assays (EC 50 =89 nM).

Store at -20℃ for one year（Powder）；Store at 2-4℃ for two weeks；Store at -20℃ for six months after dissolution.
