Abstract

The p53-MDM2 interaction has been proved to be a valuable target to develop effective antitumor agents. Novel p53-MDM2 inhibitors bearing pyrrolidone scaffolds were successfully identified by structure-based design. The nanomolar inhibitor 5 possessed good p53-MDM2 inhibitory activity (K(i) = 780 nM) due to its hydrophobic and hydrogen bonding interactions with MDM2. Further hit optimization led to the discovery of a number of highly potent pyrrolidone derivatives with improved p53-MDM2 inhibitory activity and in vitro antiproliferative potency. Compounds 41 (K(i) = 260.0 nM) and 60a (K(i) = 150.0 nM) showed good and selective activity against tumor cells with deleted p53. In addition, these two compounds also effectively inhibited the tumor growth in the A549 xenograft model. Interestingly, compound 41 was proved to be a potent MDM2/MDMX dual inhibitor. The novel pyrrolidone p53-MDM2 inhibitors represent promising lead structures for the development of novel antitumor agents.

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?

  • By employing structure-based virtual screening, they identified a quinazolinone fragment, hit 4 (Kd = 467 ± 65 nM), with two optical isomers that acted on different "hot spots" of PDEδ.

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.
