Src homology 2 domain-containing phosphatase 2 (SHP2) is an attractive therapeutic target for human cancers and other human diseases. Herein, we report our discovery of potent small-molecule SHP2 degraders whose design is based upon the proteolysis-targeting chimera (PROTAC) concept. This work has led to the discovery of potent and effective SHP2 degraders, exemplified by SHP2-D26. SHP2-D26 achieves DC50 values of 6.0 and 2.6 nM in esophageal cancer KYSE520 and acute myeloid leukemia MV4;11 cells, respectively, and is capable of reducing SHP2 protein levels by >95% in cancer cells. SHP2-D26 is >30-times more potent in inhibition of phosphorylation of extracellular signal-regulated kinase (ERK) and of cell growth than SHP099, a potent SHP2 inhibitor, in KYSE520 and MV4;11 cancer cell lines. This study demonstrates that induced SHP2 degradation is a very effective approach to inhibit the function of SHP2. Further optimization of these SHP2 degraders may lead to the development of a new class of therapies for cancers and other human diseases.

GPX4 protein degradation agent, preparation method and application thereof, and antitumor cell drug
-
Paragraph 0317-0320, (2021/09/04)
The invention provides a GPX4 protein degradation agent, a preparation method thereof, and an anti-tumor cell drug, and belongs to the technical field of drug application. The GPX4 protein degradation agent provided by the invention has a protein degradation targeting chimera (PROTAC) molecular structure, a mother nucleus structure of the GPX4 protein degradation agent is used as a small molecule ligand for combining target protein, an A2 substituent is used as a small molecule ligand for combining an E3 ubiquitin ligase compound, and an A1 substituent is used as a connecting group for connecting the two ligands. The GPX4 protein degradation agent with the structure can specifically recognize GPX4 protein and effectively ubiquitinate and degrade the GPX4 protein, so that tumor cell ferroptosis is induced.
