Abstract

Structural biology is a powerful tool for investigating the stereospecific interactions between a protein and its ligand. Herein, an unprecedented chiral binding pattern was observed for inhibitors of KRAS-PDEδ interactions. Virtual screening and X-ray crystallography studies revealed that two enantiomers of a racemic inhibitor could bind at different sites. Fragment-based drug design was used to identify highly potent PDEδ inhibitors that can be used as promising lead compounds for target validation and antitumor drug development.

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?

  • Both compound (125) and compound (126) effectively inhibited KRAS-PDEδ PPI, disrupted the correct localization of KRAS on the cell membrane, down-regulated the phosphorylation of key proteins Erk and Akt in the downstream pathway of KRAS, and induced apoptosis in KRAS-mutated pancreatic cancer cell lines.

    “Ultimately, both compound (125) and compound (126) effectively inhibited KRAS-PDEδ PPI, disrupted the correct localization of KRAS on the cell membrane, down-regulated the phosphorylation of key proteins Erk and Akt in the downstream pathway of KRAS, and induced apoptosis in KRAS-mutated pancreatic cancer cell lines.353”

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.
