Abstract

Restoration of p53 activity by inhibition of the p53-MDM2 interaction has been considered an attractive approach for cancer treatment. However, the hydrophobic protein-protein interaction surface represents a significant challenge for the development of small-molecule inhibitors with desirable pharmacological profiles. RG7112 was the first small-molecule p53-MDM2 inhibitor in clinical development. Here, we report the discovery and characterization of a second generation clinical MDM2 inhibitor, RG7388, with superior potency and selectivity.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • RG-7388 (idasanutlin) is the first potent oral MDM2 protein inhibitor developed by Roche.

    “RG-7388 (149), also known as idasanutlin, is the first potent oral MDM2 protein inhibitor developed by Roche.399”
  • RG-7388 can effectively activate the p53 pathway, induce wild type p53 expression, trigger cell cycle block or apoptosis, and inhibit tumor proliferation in neuroblastoma transplant tumor.

    “With its exceptional activity and selectivity, RG-7388 can effectively activate the p53 pathway, induce wild type p53 expression, trigger cell cycle block or apoptosis, and inhibit tumor proliferation in neuroblastoma transplant tumor.”
  • RG-7388's inhibitory activity (IC50 = 6 nM) is three times that of RG-7112 (IC50 = 18 nM).

    “Notably, RG-7388’s inhibitory activity (IC50 = 6 nM) is three times that of RG-7112 (IC50 = 18 nM).399,400”
  • WB138 increases levels of both p53 and MDM2, consistent with previous reports on MDM2 inhibitors.

    “WB138 increases the levels of both p53 and MDM2, which is consistent with the activity of previous reports on MDM2 inhibitors[28,32–36].”
  • RG7388 binding activity to MDM2 reached 6 nM, antiproliferative activity against various tumor cells with high expression of wild-type p53 was approximately 300 nM, selectivity over p53 mutant tumor cells was greater than 100 times, oral bioavailability in mice reached 80%, half-life was 1.6 h, and metabolic stability was better than Compounds 1 and 2.

    “The binding activity of RG7388 to MDM2 reached 6 nM, and the antiproliferative activity against various tumor cells with high expression of wild-type p53 was approximately 300 nM. The selectivity over p53 mutant tumor cells was greater than 100 times. The oral bioavailability in mice reached 80%, half-life was 1.6 h, and the metabolic stability was better than those of Compounds 1 and 2.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
