ARV-771 is a BET PROTAC degrader, with K_d 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].

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].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
