Biological Activity

MTX-23 is a proteolysis targeting chimera (PROTAC) degrader of androgen receptor (AR) splice variant-7 (AR-V7) and AR-full length (AR-FL) with DC50 of 0.37 and 2 uM, respectively.
MTX-23 simultaneously binds AR's DNA binding domain (DBD) and the Von Hippel-Lindau (VHL) E3 ubiquitin ligase.
MTX-23 inhibits prostate cancer cellular proliferation and increased apoptosis only in androgen-responsive prostate cancer cells.
MTX-23 (1 uM) stimulates apoptosis in 22Rv1 cells, induces poly-ubiquitination of AR-V7 and AR-FL.
MTX-23 is effective against SAT-resistant prostate cancer cell lines, inhibits enzalutamide-resistant prostate cancer growth in mice.
