Customer Review

Based on 1 Customer Validation

ARD-61 is a highly potent, effective and specific PROTAC androgen receptor (AR) degrader. ARD-61 potently and effectively induces AR and progesterone receptors (PR) degradation in AR+ cancer cell lines. ARD-61 induces apoptosis and effectively induces tumor growth inhibition in the MDA-MB-453 xenograft model in mice. ARD-61 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

In Vitro

ARD-61 binds to AR protein through its AR antagonist portion and von Hippel-Lindau (VHL)/cullin 2 E3 ligase through its VHL ligand portion to recruit AR protein to cullin 2 for ubiquitination, followed by proteasome-dependent AR degradation^[1].
ARD-61 (0.001-100 μM; for 7 days) has IC₅₀ values of 235 nM and 121 nM in the MDA-MB-453 and HCC1428 cell lines, which have the highest AR expression, respectively. ARD-61 demonstrates partial cell growth inhibition, delivering IC₅₀ values of 39, 147, and 380 nM, respectively, in the MCF-7, BT-549 and MDA-MB-415 cell lines, which have a moderate level of AR protein^[1].
ARD-61 (25-100000 nM; 6-72 h) induces G2/M cell cycle arrest in a dose- and time-dependent manner in each of these three AR+ breast cancer cell lines^[1].
ARD-61 (25-100000 nM; 72 h) induces apoptosis in the MDA-MB-453 and HCC1428 cell lines^[1].
ARD-61 (0.01-1000 nM; 6 h) is highly potent and effective in reducing AR protein levels. ARD-61 (0.01-1000 nM; 24 h) reduces the level of PR protein with a DC₅₀ value of 0.15 nM in the T47D cells. ARD-61 has no obvious effect on ER and GR proteins^[1].
ARD-61 (1 μM; for 24 h) effectively inhibits Wnt/β-catenin and MYC signaling pathways. ARD-61 (1-1000 nM; for 24 h) not only decreases both phosphorylated HER2 and HER3, but also un-phosphorylated HER2 and HER3 proteins^[1].
Efficient knock-down of VHL completely blocks AR degradation induced by ARD-61 (100 nM; 24 h) in both MDA-MB-453 and MCF-7 cell lines^[1].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

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.
