LYA914
LYA914 is an orally effective AR/AR-V7 PROTAC degrader. LYA914 recruits CRBN to target and bind the conserved DBD domain of AR and AR-V7, inducing their ubiquitination and subsequent degradation, thereby completely blocking AR signaling and transcriptional activity. LYA914 can be used for the research of castration-resistant prostate cancer.

LYA914 (0.01-10 μM; 24 h) potently degrades AR (DC50 = 0.41 μM) and AR-V7 (DC50 = 0.32 μM) in a dose-dependent manner in 22Rv1 prostate cancer cells, and potently degrades AR (DC50 = 0.83 μM) and AR-V7 (DC50 = 0.33 μM) in a dose-dependent manner in VCaP prostate cancer cells[1].
LYA914 (3 μM; 2-24 h) induces time-dependent degradation of AR in LNCaP cells, with degradation initiating at 6 h and reaching the maximum degradation rate at 24 h[1].
LYA914 (1 μM; 12 h) enhances the binding of CRBN to AR and promotes AR ubiquitination in 22Rv1 cells pre-treated with MG132 (HY-13259)[1].
LYA914 (24 h) potently inhibits AR- and AR-V7-driven transcriptional activity in 293T cells overexpressing AR or AR-V7[1].
LYA914 (1-3 μM; 48 h) significantly downregulates the mRNA expression of AR-regulated genes and AR-V7-regulated genes in 22Rv1 cells[1].
LYA914 (4-6 days) inhibits the viability of LNCaP (IC50 = 1.21 μM), 22Rv1 (IC50 = 1.15 μM), LNCaP-EN (IC50 = 4.12 μM) and VCaP-EN (IC50 = 1.66 μM) cells in a concentration-dependent manner, and exhibits extremely low toxicity to the human normal liver tissue cell line HL-7702 (IC50 > 30 μM)[1].

Dual Luciferin reporter gene assay
Luciferin reporter gene assay is a reporting system to detect the activity of Firefly Luciferase using luciferin as a substrate, which is often used in the research of miRNA target gene verification and promoter transcriptive activity regulation. Dual luciferase usually refers to Firefly luciferase and Renilla luciferase.
