    IC50 & Target


    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].

    Cell Assay

    Nutlin-3a is dissolved in DMSO and stored, and then diluted with appropriate media before use[1].

    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]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration

    Nutlin-3a is prepared in 1% Klucel, 0.1% Tween 80 (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. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
