Abstract
The Ataxia telangiectasia and RAD3-related (ATR) kinase is a key regulator of DNA replication stress responses and DNA-damage checkpoints. Several potent and selective ATR inhibitors are reported and four of them are currently in clinical trials in combination with radio- or chemotherapy. Based on the idea of degrading target proteins rather than inhibiting them, we designed, synthesized and biologically characterized a library of ATR-targeted proteolysis targeting chimera (PROTACs). Among the synthesized compounds, the lenalidomide-based PROTAC 42i was the most promising. In pancreatic and cervix cancer cells cancer cells, it reduced ATR to 40 % of the levels in untreated cells. 42i selectively degraded ATR through the proteasome, dependent on the E3 ubiquitin ligase component cereblon, and without affecting the associated kinases ATM and DNA-PKcs. 42i may be a promising candidate for further optimization and biological characterization in various cancer cells.

Abstract
Overexpression of histone deacetylase 8 (HDAC8) is associated with various diseases such as cancer. Thus, compounds that can modulate HDAC8 levels have therapeutic potential for these diseases. Based on the proteolysis targeting chimera (PROTAC) strategy, we designed and synthesized a series of HDAC8 degraders by tethering an HDAC6/8 dual inhibitor with pomalidomide (a cereblon ligand). Among them, compound ZQ-23 exhibited significant and selective degradation of HDAC8 with DC50 of 147 nM and Dmax of 93%, and exhibited no effects on HDAC1 and HDAC3. Interestingly, we found that the degradation of target protein started at ∼2 h after treatment with ZQ-23 and the maximal degradation effect was achieved at 10 h. The HDAC8 level was partially recovered within 24 h. In addition, ZQ-23 had no degrading effects on HDAC1 and HDAC3 at all concentrations, but could dose-dependently increase the levels of acetylated SMC-3 (HDAC8 substrate). Mechanism study demonstrated that ZQ-23 degraded HDAC8 through the ubiquitin-protease pathway, rather than lysosome system. Collectively, these results suggest that ZQ-23 represents a novel PROTAC-based HDAC8 degrader worthy of further investigation.

Abstract
SHP2, a non-receptor tyrosine phosphatase, plays a pivotal role in numerous oncogenic cell-signaling cascades like RAS-ERK, PI3K-AKT and JAK-STAT. On the other hand, proteolysis targeting chimera (PROTAC) has emerged as a promising strategy for the degradation of disease-related protein of interest (POI). SHP2 degradation via the PROTAC strategy will provide an alternative startegy for SHP2-mediated cancer therapy. Herein we described the design, synthesis and evaluation of a series of thalidomide-based heterobifunctional molecules and identified 11(ZB-S-29) as the highly efficient SHP2 degrader with a DC50 of 6.02 nM. Further mechanism investigation illustrated that 11 came into function through targeted SHP2 protein degradation.

Abstract
A series of PROTAC (proteolysis targeting chimera) based selective EGFRL858R/T790M (leucine 858 to arginine 858 mutation and threonine 790 to methionine 790) mutant degraders were designed and synthesized. One of the most potent compounds, 14o, effectively and selectively degraded EGFRL858R/T790M with an DC50 value of 5.9 nM, while did not show obvious effect on the wild-type protein. Further mechanism investigation revealed that the degradation was mediated by ubiquitin proteasome pathway. Compound 14o could be utilized as an initial lead molecule for development of new EGFRL858R/T790M degrader based therapy.
