ARV-771
Based on 30 publication(s) in Google Scholar
ARV-771 is a BET PROTAC degrader, with Kd values of 34, 4.7, 8.3, 7.6, 9.6 and 7.6 nM against BRD2 (1), BRD2 (2), BRD3 (1), BRD3 (2), BRD4 (1) and BRD4 (2) , respectively. ARV-771 inhibits the transcription of AR/AR-v7 and its downstream target genes. By degrading BRD4 protein, ARV-771 enhances the sensitivity of prostate cancer cells to ferroptosis, suppresses cancer cell viability, and induces apoptosis. ARV-771 downregulates the levels of BRD4, c-MYC and AR-V7 in tumor tissues and inhibits tumor tissue growth. ARV-771 can be used in prostate cancer-related research.

In Vitro
ARV-771 (72 h) potently inhibits cell viability, with an IC50 of 10.68 nM in 22Rv1 cells and 25.19 nM in PC-3 cells; it also induces concentration-dependent BRD4 degradation, with stronger activity observed in 22Rv1 cells[1].
ARV-771 (3-300 nM; 18 h) induces concentration-dependent degradation of BRD4 in 22Rv1 and PC-3 cells, with stronger activity observed in 22Rv1 cells[1].
ARV-771 downregulates the expression of BRD4 protein in 22Rv1 cells, and its proteomic profile shows that compared with the ARV@MIL-HA-ss-HA formulation, there are fewer tumor suppressor proteins and more oncoproteins[1].
ARV-771 (10 nM; 16 h) downregulates FL-AR and AR-V7 mRNA levels in VCaP cells and exerts antiandrogenic effects on multiple AR-regulated genes[2].
ARV-771 induces apoptosis in 22Rv1 cells, with a total apoptosis rate of 33.25%[1].

Result:Significantly downregulated the mRNA levels of FL-AR and AR-V7.
Exhibited anti-androgenic effects on multiple AR-regulated genes, inhibiting the expression of androgen-responsive genes. Pretreatment for 1 hour completely blocked the expression of the ERG gene induced by the synthetic androgen R1881.
In RNA sequencing experiments in 22Rv1 cells, the expression of seven AR-regulated genes-ELL2, PMEPA1, STEAP1, FAM105A, ATAD2, ENDOD1, and ZNF189-was downregulated by more than 50%.
In Vivo
ARV-771 (10-30 mg/kg; subcutaneous injection; once daily; for 14 consecutive days) downregulates the levels of both BRD4 and c-MYC in tumor tissues of 22Rv1 tumor xenograft mice, and inhibits tumor growth in these mice in a dose-dependent manner[2].
ARV-771 (administered subcutaneously; once every 3 days or on a 3-day-on/4-day-off schedule; for a total of 16 days) achieves a 60% tumor growth inhibition rate in VCaP tumor xenograft mice, reduces BRD4 expression by 57% and c-MYC expression by 88% in tumor tissues, and decreases serum PSA by 60%-80%[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
