LYA914
LYA914 is an orally active AR/AR-V7 PROTAC degrader. LYA914 targets the proteolytic degradation of the conserved DNA binding domain (DBD) of the androgen receptor (AR). LYA914 exhibits potent antiproliferative effects in Enzalutamide (HY-70002)-insensitive/resistant cells. LYA914 inhibits tumor growth in VCaP/LNCaP tumor mouse models. LYA914 can be used to study castration-resistant prostate cancer (CRPC).

LYA914 (1-10 μM) degrades AR protein in LNCaP cells, 22Rv1 cells with degradation rates of 40.2% and 39.1% at 1 μM, and 82.5% and 84.5% at 10 μM, degrades AR-V7 protein in 22Rv1 cells with degradation rates of 37.4% at 1 μM, and 83.9% at 10 μM[1].
LYA914 (0.01-10 μM, 24 h) enhances the binding of CRBN and AR, and induces the degradation of AR and AR-V7, the DC50s in 22RV1 cells are 0.41 and 0.83 μM, respectively, and the DC50s in vcaP cells are 0.32 and 0.33 μM, respectively, also induces the degradation of AR and AR-V7 in LNCaP cells[1].
LYA914 (24 h) inhibits AR/AR-V7-driven transcriptional activity in overexpressed AR or AR-V7 and the reporter plasmid in 293T cells, with IC50s of 0.19 and 1.29 μM[1].
LYA914 (1-3 μM, 48 h) shows a significant blockade on the AR/AR-V7 signaling pathway by transcriptional inhibition in 22Rv1 cells[1].
LYA914 (5 days) shows antiproliferation activity in LNCaP, VCaP, 22Rv1 cells, with IC50s of 1.21, 1.6, 1.15 μM, shows low cytotoxicity against HL-7702 cells[1].
LYA914 (6 days) remains the antiproliferative effects against LNCaP-EN and VCaP-EN cells with Enzalutamide (HY-70002) exposure, with IC50s of 4.12 and 1.66 μM[1].
LYA914 (24 h) shows significant inhibition on the transcriptional activity of HEK293T cells with AR reporter plasmids are cotransfected with AR (F876L) or AR (W741L) plasmids, respectively, with IC50s of 1.29 and 0.53 μM[1].
