Abstract

Mirror-image screening using d-proteins is a powerful approach to provide mirror-image structures of chiral natural products for drug screening. During the course of our screening study for novel MDM2-p53 interaction inhibitors, we identified that NPD6878 (R-(-)-apomorphine) inhibited both the native l-MDM2-l-p53 interaction and the mirror-image d-MDM2-d-p53 interaction at equipotent doses. In addition, both enantiomers of apomorphine showed potent inhibitory activity against the native MDM2-p53 interaction. In this study, we investigated the inhibitory mechanism of both enantiomers of apomorphine against the MDM2-p53 interaction. Achiral oxoapomorphine, which was converted from chiral apomorphines under aerobic conditions, served as the reactive species to form a covalent bond at Cys77 of MDM2, leading to the inhibitory effect against the binding to p53.

  • In 2017, Ishiba et al. revealed NPD6878 (apomorphine) as an MDM2-p53 inhibitor candidate with high potency.

    “In 2017, Ishiba et al. performed mirror-image screening through D-proteins, which is an approach for identifying potential pharmaceutical candidates from homochiral resources, and revealed that NPD6878 (apomorphine) (75) was an MDM2–p53 inhibitor candidate with high potency.”

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.
