Novel PROTACs for degradation of SHP2 protein
Abstract
Protein tyrosine phosphatase SHP2 is a member of PTPs family associated with cancer such as leukemia, non-small cell lung cancer, breast cancer, and so on. SHP2 is a promising target for drug development, and consequently it is of great significance to develop SHP2 inhibitors. Herein, we report CRBN-recruiting PROTAC molecules targeting SHP2 by connecting pomalidomide with SHP099, an allosteric inhibitor of SHP2. Among them, SP4 significantly inhibited the growth of Hela cells, compared with SHP099, its activity increased 100 times. In addition, it can significantly induce SHP2 degradation and cell apoptosis. Further study of SHP2-protac may have important significance for the treatment of SHP2 related diseases.

SP4 (205) and ZB-S-29 (206) effectively degrade SHP2 in KYSE520 cells.
“These compounds, SP4 (205) (SHP2WT IC50 = 4.3 nM in Hela cells)498 and ZB-S-29 (206)499 (SHP2WT IC50 = 0.207 μM in MV4;11 cells), effectively degraded SHP2 in KYSE520 cells (Table 4).”

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.
