MBM-55 (compound 42g) is a potent NIMA-related kinase 2 (Nek2) inhibitor with an IC50 of 1 nM. MBM-55 shows a 20-fold or greater selectivity in most kinases with the exception of RSK1 (IC50=5.4 nM) and DYRK1a (IC50=6.5 nM). MBM-55 effectively inhibits the proliferation of cancer cells by inducing cell cycle arrest and apoptosis. MBM-55 shows antitumor activities, and no obvious toxicity to mice[1]. IC50: 1 nM (Nek2), 5.4 nM (RSK1), 6.5 nM (DYRK1a), 57 nM (CHK1), 91 nM (GSK-3β), 20 nM (ABL), 370 nM (CDK2), 441nM (CDK4), 608 nM (AKT1), 5300 nM (Aurora A)[1]
MBM-55 inhibits MGC-803, HCT-116, Bel-7402 cells proliferation with IC50s of 0.53, 0.84, 7.13 μM, respectively[1].MBM-55 (0.5-1 μM; 24 hours) induces G2/M phase arrest and accumulation of cells with >4N content in HCT-116 cells[1].MBM-55 (0.5-1 μM; 24 hours) causes cell apoptosis in a concentration-dependent manner in HCT-116 cells[1]. Cell Cycle Analysis[1] Cell Line: HCT-116 cells
MBM-55 (20 mg/kg; i.p.; twice a day for 21 days) exhibits good antitumor activity and a well-tolerated dose schedule in nude mice bearing HCT-116 xenografts[1]. Animal Model: Female BALB/c nu/nu mice (5-6 weeks, bearing HCT-116 xenografts)[1]

Structure-based design and synthesis of imidazo[1,2-a]pyridine derivatives as novel and potent Nek2 inhibitors with in vitro and in vivo antitumor activities
Eur J Med Chem 2017 Jan 27;126:1083-1106.PMID:28039836DOI:10.1016/j.ejmech.2016.12.026
We present herein the discovery and development of novel and potent Nek2 inhibitors with distinctive in vitro and in vivo antitumor activity based on an imidazo[1,2-a]pyridine scaffold. Our studies identified a nonlinear SAR for activity against both Nek2 and cancer cells. Bioisostere and structure-based design techniques were employed to identify compounds 42c (MBM-17, IC50 = 3.0 nM) and 42g (MBM-55, IC50 = 1.0 nM), which displayed low nanomolar activity and excellent selectivity for Nek2. Both compounds effectively inhibited the proliferation of cancer cells by inducing cell cycle arrest and apoptosis. Importantly, the salts form of these two compounds (MBM-17S and MBM-55S) significantly suppressed tumor growth in vivo without apparent toxicity based on appearance and changes in body weight. In summary, MBM-17 and MBM-55 displayed the potential for substantial therapeutic application in cancer treatment.
