| | SP 141 Usage And Synthesis |
| Description | Mouse double minute 2 protein (MDM2) is an E3 ubiquitin-protein ligase that binds and ubiquitinates the tumor suppressor p53, leading to its degradation by the proteasome. SP 141 is a cell-permeable inhibitor of MDM2 (Ki = 28 nM). Binding of MDM2 by SP 141 promotes its auto-ubiquitination and proteasomal degradation. SP 141 induces cell cycle arrest and apoptosis in breast and pancreatic cancer cell lines and inhibits xenograft tumor growth in vivo. This compound has a short half-life in plasma and wide tissue distribution in tumor-bearing nude mice. | | Uses | SP 141 induces cell cycle arrest and apoptosis in breast and pancreatic cancer cell lines, inhibiting xenograft tumor growth in vivo. | | in vivo | SP-141 (40 mg/kg; administered by i.p. injection; 5 d/wk for about three weeks) suppresses pancreatic tumor growth in both xenograft and orthotopic mouse models[1].
| Animal Model: | Nude mice bearing Panc-1 xenograft tumors[1] | | Dosage: | 40 mg/kg | | Administration: | Administered by i.p. injection; 5 d/wk for about three weeks | | Result: | Significantly suppressed the growth of pancreatic xenograft tumors. On Day 18, the tumor volume in the treated group was reduced by 75% compared with that in the control group. There were no significant differences in the body weight compared with the control group. |
