General description
A cell permeable, bioavailable D-tripeptide that specifically binds to MKK7 in 1:1 stoichiometry and disrupts the GADD45b/MKK7 complex in an allosteric mechanism (Kd = 65 nM, IC50 = 160 pM). Does not affect the activity of 142 other protein kinases. Exhibits potent and selective activity in both multiple myeloma (MM) and non-MM cell lines expressing high levels of GADD45b, however, it is completely inactive in tumor cells featuring low GADDb expression. Displays potency similar to bortezomib, but has about 100-fold greater selectivity for cancer cells, and unlike bortezomib, it does not display any toxic effects in normal cell lines. Shown to activate JNK, but does not affect p38, ERK, or IKK/NF-κB signaling in sensitive GADD45b dependent MM cell lines. Abolishes the growth of myeloma xenografts in mice (14.5 mg/kg/day) and retains anticancer activity in an orthotopic xenograft model of MM. Displays desirable pharmacokinetic profile (t1/2 = 1.26 h and AUC = 6.43 mg/h/ml; at ~10 mg/kg, i.v).
