Abstract

In tumor cells, p53 is always inactivated due to the mutation or deletion of TP53 gene or inhibited by the overexpressed MDM2. Small-molecule induced restoring of p53 function by blocking MDM2-p53 protein-protein interactions has been highly pursued as an attractive therapeutic strategy for cancer therapy. To date, a large number of small-molecule inhibitors have been identified based on the compact and well-defined MDM2-p53 interactions, of which SAR405838, MK-8242, DS-3032b, NVP-CGM097, RG7112, HDM201, RG7388, ALRN-6924 and AMG 232 are undergoing clinical assessment at different phases for cancer therapy. This review is focused on the discovery and development of piperidinone-based MDM2-p53 inhibitors for cancer therapy, including the identification of hit compounds, hit-to-lead optimizations, binding models of ligands in the active site of MDM2, metabolic studies, and preclinical data of advanced piperidinone-based MDM2-p53 inhibitors. Additionally, acquired resistance of MDM2 inhibitors and potential toxicity toward normal tissues are briefly discussed.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • MK-8242 exhibited a strong inhibitory effect on wild-type PPTP cells with an IC50 value of 0.07 μM, but had weak inhibitory effects on TP53-mutant PPTP cells with an IC50 value greater than 10 μM, indicating a selectivity of more than 100 times.

  • In vivo studies demonstrated that MK-8242 delayed tumor growth by a factor of two or more in 10 of 17 solid tumor xenografts containing wild-type TP53, but had no effect on osteosarcoma xenografts with low TP53 expression.

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.
