SP 141 is a specific, potent and selective small-molecule antagonist of MDM2 with Ki value of 28±6 nM [2][3][4].
Mouse double minute 2 protein (Mdm2) is an ubiquitin ligase that promotes p53 degradation, a tumor suppressor that controls a major pathway protecting cells from malignant transformation [1].
SP 141 is a potent and selective MDM2 inhibitor. In breast cancer cell lines, SP-141 reduced cell viability with IC50 less than 1 μM (0.39-0.91 μM) and inhibited cancer cell colony formation in a concentration-dependent way. SP-141 also increased apoptosis and concentration-dependently inhibited cell proliferation. In both MCF-7 and MDA-MB-468 cells, SP-141 increased the degradation rate of the MDM2 protein [2].
In nude mice bearing MCF-7 and MDA-MB-468 xenograft tumours, intraperitoneal (i.p.) injection of SP-141 inhibited tumour growth by ~82% and ~80%, respectively [2]. In pancreatic xenograft and orthotopic mouse models, intraperitoneal (i.p.) injections of SP141 significantly inhibited the growth of pancreatic xenograft tumors and caused complete tumor regression of orthotopic pancreatic tumors [3]. In tumor-bearing nude mice, SP-141 had a short half-life in plasma and wide tissue distribution [4].
