PROTAC FAK degrader 2 (Compound F2) is a PROTAC degrader for focal adhesion kinase (FAK), with DC50 of 27.72 and 60.1 nM, for total FAK and phosphorylated p-FAK. PROTAC FAK degrader 2 inhibits cell viability of cancer cells 4T1, MDA-MB-231, MDA-MB-468 and MDA-MB-435, with IC50s of 0.73-5.84 μM. PROTAC FAK degrader 2 reverses the multidrug resistance (MDR) through inhibition of AKT and ERK signaling pathway. PROTAC FAK degrader 2 exhibits antitumor efficacy in HCT/8 xenograft mouse model.
