Description
Nutlin-3a (Rebemadlin), an active enantiomer of Nutlin-3, is a potent murine double minute (MDM2) inhibitor (IC50=90 nM). Nutlin-3a inhibits MDM2-p53?interactions and stabilizes the p53 protein, and induces cell autophagy and apoptosis. Nutlin-3a has the potential for the study of TP53?wild-type ovarian carcinomas[1][2].
IC50 & Target
MDM2-p53[1]
In Vitro
Nutlin-3a is a therapeutic which inhibits MDM2, activates wild-type p53, and induces apoptosis-as a therapeutic compound for TP53 wild-type ovarian carcinomas. Three cell lines (HOC-7, OVCA429 and A2780) with wild-type TP53 are highly sensitive to Nutlin-3a (IC50=4 to 6 μM). SKOV3 cells have an IC50 of 38 μM to Nutlin-3a. The two remaining ovarian clear cell lines (TOV21G and OVAS), both with TP53 wild-type, are relatively more sensitive to growth inhibition with Nutlin-3a (IC50=14 and 25 μm respectively) than the TP53 mutant cell lines[1]. Nutlin-3a is the active enantiomer of Nutlin-3. Nutlin-3a is a highly selective MDM2 antagonist and p53 inducer. Seven days of incubation with 10 μM Nutlin-3a leads to >90% inhibition of NIH/3T3 cells’growth but does not affect the proliferation of MEF in which both targets of the drug are eliminated. Nutlin-3a effectively arrestes cell-cycle progression in all cell lines, depleting the S-phase compartment to 0.2-2% and increasing the G1- and G2/M-phase compartments, indicating G1 and G2 arrest. The p53 targets p21 and MDM2 are elevated significantly 3 h after Nutlin-3a addition and reach maximal levels at 8 h. Nutlin-3a induces apoptosis in ≈60% of SJSA-1 and MHM cells after 40 h, which increase further after 60 h (85% and 65%, respectively)[2].

In Vivo
Nutlin-3a is efficacious in all models with average tumor growth inhibition ≥98%. Nutlin-3a suppresses xenograft growth in a dose-dependent fashion with the highest dose (200 mg/kg) showing a substantial tumor shrinkage (eight partial and one full regressions). The established SJSA-1 and MHM osteosarcoma xenografts with Nutlin-3a causes extensive tumor regression[2].

[Content Brief]
All 15 cell lines are plated at a density of 1×103 cells per well in 96-well plates. After 24h, media is exchanged and cells are treated with incremental concentrations of Nutlin 3a (1 μM, 5 μM, 10 μM, 25 μM, 50 μM, and 70 μM). After 72 h of incubation, WST-1 is added to each well, and a microplate reader is used at an absorbance of 450 nm to measure the number of remaining viable cells. Experiments are repeated with smaller titrations of Nutlin 3a as needed to determine the exact IC50 of cell lines. The IC50 is defined. Cell lines are again plated in a manner identical to above and treated with Nutlin 3a at their respective IC50, and WST-1 is added with cell viability measurement at 24, 48, and 72h[1].

Animal Administration
[2]
Mice[2] Nude mice bearing s.c. tumor xenografts (10 mice per group in the SJSA-1, LnCaP, and 22Rv1 study and 15 mice per group in the MHM study) are dosed orally twice daily with Nutlin 3a (50-200 mg/kg) or vehicle (1% Klucel, 0.1% Tween 80) for 2 weeks (22Rv1 and LnCap) or 3 weeks (SJSA-1 and MHM). Tumor volume is measured with a caliper and calculated. For Western blot analysis, nude mice with established SJSA-1 tumors (200-400 mm3, three animals per group are treated with three doses of Nutlin 3a at 150 mg/kg (at 0, 8, and 24 h), and tumors are harvested 3 h after the last dose. Tumor samples are flash-frozen and processed[2].

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
