– PROTAC AR Degrader-8 (Compound NP18) functions as a PROTAC degrader targeting the androgen receptor (AR) and effectively degrades AR-FL in both 22Rv1 and LNCaP cells with DC50 values of 0.018 μM and 0.14 μM, respectively. It also degrades AR-V7 in 22Rv1 cells with a DC50 of 0.026 μM. Additionally, PROTAC AR Degrader-8 inhibits the proliferation of 22Rv1 and LNCaP cancer cells, exhibiting IC50 values of 0.038 μM and 1.11 μM. It induces cell cycle arrest at the G2/M phase and triggers apoptosis in 22Rv1 cells (apoptosis). Demonstrating anticancer efficacy, PROTAC AR Degrader-8 shows activity in both mouse and zebrafish models.
