STAT3-D11-PROTAC-VHL

STAT3-D11-PROTAC-VHL (Compound D11-PROTAC) is a PROTAC degrader targeting Signal Transducer and Activator of Transcription 3 (STAT3) . STAT3-D11-PROTAC-VHL exhibits anti-tumor activity with IC50 values of 1335 nM and 1973 nM against HeLa and MCF-7 cells, respectively. STAT3-D11-PROTAC-VHL binds to the DNA-binding domain of STAT3 and recruits the E3 ligase VHL to form a ternary complex, leading to the ubiquitination of STAT3 and subsequent degradation by the proteasome. STAT3-D11-PROTAC-VHL also inhibits tumor cell growth, induces cell cycle arrest and apoptosis, and suppresses tumor immune evasion[1].
