PROTAC ALK degrader-4

PROTAC ALK degrader-4 (Compound B8) is an ALK PROTAC degrader with a DC50 of 445.25 nM. PROTAC ALK degrader-4 exhibits excellent anti-proliferative activity against NCI-H2228 and NCI-H3122. PROTAC ALK degrader-4 leads to a significant downregulation of 390 proteins, including IGF-1R and its downstream proteins such as ERK1/2 and STAT3. PROTAC ALK degrader-4 can be used for research on lung adenocarcinoma. (Pink: ALK ligand (HY-15656) ; Blue: CRBN ligand (HY-179733) ; Black: linker) [1].
