EGFR/ErbB1/HER1 Degrader

Petosemtamab (MCLA 158) is an anti- EGFR (K_d: 0.22 nM) and anti-LGR5 (K_d: 0.86 nM) monoclonal antibody (mAb). Petosemtamab leads to EGFR signaling blockade and receptor degradation in LGR5+ cancer cells. Petosemtamab can be used in the research of solid tumors, such as head and neck squamous cell carcinoma (HNSCC), metastatic colorectal cancer (CRC).

PROTAC EGFR degrader 7 (compound 13b) is a potent and selective CRBN-recruiting PROTAC EGFR^L858R/T790M degrader, with a DC₅₀ of 13.2 nM. PROTAC EGFR degrader 7 inhibits NCI–H1975 cells proliferation, with an IC₅₀ of 46.82 nM. PROTAC EGFR degrader 7 significantly induces apoptosis and G2/M phase arrest in NCI–H1975 cell. PROTAC EGFR degrader 7 shows antitumor activity, and can be used for non-small cell lung cancer (NSCLC) research. PROTAC EGFR degrader 7 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

PROTAC EGFR degrader 4 is an EGFR^del19 and EGFR^L858R/T790M degrader with anti-proliferative activity. PROTAC EGFR degrader 4 induces degradation of mutant EGFR variants via ubiquitination and autophagy. PROTAC EGFR degrader 4 suppresses EGFR pathway signal transduction. PROTAC EGFR degrader 4 induces apoptosis, arrests cell cycle, and suppresses cell colony formation in cancer cells. PROTAC EGFR degrader 4 can be used for the research of non-small cell lung cancer.

DDC-01-163 is an allosteric PROTAC degrader targeting EGFR. DDC-01-163 is dependent on the ubiquitin–proteasome system. DDC-01-163 can selectively inhibit the proliferation of L858R/T790M (L/T) mutant Ba/F3 cells. DDC-01-163 is effective against Osimertinib (HY-15772)-resistant cells with L/T/C797S and L/T/L718Q EGFR mutations. DDC-01-163 exhibits enhanced anti-proliferative activity against L858R/T790M EGFR-Ba/F3 cells when combined with the ATP-site EGFR inhibitor Osimertinib. DDC-01-163 can be used for the study of non-small cell lung cancer.

MS9427 is a potent PROTAC EGFR degrader with K_ds of 7.1 nM and 4.3 nM for EGFR WT and EGFR L858R, respectively. MS9427 selectively degrades the mutant but not the WT EGFR through both the ubiquitin/proteasome system (UPS) and autophagy/lysosome pathways. MS9427 potently inhibits the proliferation of NSCLC cells. MS9427 can be used for researching anticancer.

ZSH-2117 is an NEDD4-recruiting EGFR PROTAC degrader. ZSH-2117 shows an IC₅₀ of 13 nM against EGFR^{L858R/T790M/C797S}, induces EGFR proteasome-dependent degradation, inhibits the downstream signaling pathways of EGFR, including the phosphorylation of AKT and ERK, suppresses cancer cell proliferation, and exhibits in vivo anti-tumor activity. ZSH-2117 can be used in research related to non-small cell lung cancer.

HSP90-IN-11 is a HSP90 inhibitor with an IC₅₀ of 27.8 nM. HSP90-IN-11 inhibits the activity of HSP90, which in turn induces rapid degradation of EGFR and Akt proteins in non-small cell lung cancer (NSCLC) cells. HSP90-IN-11 induces accumulation of the G1 subphase cell population in NSCLC cells, activates caspase-3, caspase-8, caspase-9 and PARP, thereby triggering apoptosis. HSP90-IN-11 exhibits antiproliferative activity in colorectal cancer and NSCLC cells. HSP90-IN-11 can be used for the research of colorectal cancer and non-small cell lung cancer.

PROTAC EGFR degrader 16 is a selective EGFR PROTAC degrader with a DC₅₀ value of < 50 nM. PROTAC EGFR degrader 16 can be used for the study of EGFR-driven cancerssuch as non-small cell lung cancer.
