生物活性:
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.
体内研究:
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.
体外研究:
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. 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).
