Kundenbewertung

Based on 1 Customer Validation

RK-582 is a tankyrase inhibitor, antitumor agent, and orally bioavailable growth inhibitor, with an IC₅₀ of 36.1 nM against human tankyrase-1 and an IC₅₀ of 39.2 nM against human tankyrase-2. In APC-mutated colorectal cancer cells, the sensitivity to RK-582 correlates with the level of active β-catenin, while drug resistance associates with PIK3CA mutation. RK-582 can be used for the research of colorectal cancer.

In Vitro

RK-582 (0.001-1 μM; 5 days) exhibits high or intermediate sensitivity in short APC-mutated CRC PDCs, while long APC-mutated CRC PDCs show variable sensitivity; RK-582 sensitivity negatively correlates with active β-catenin levels in both overall and long APC-type CRC PDCs^[1].
RK-582 (0.3 μM; 24 h) induces AXIN2 accumulation and reduces active β-catenin levels in short APC-mutated CRC PDCs, but does not alter active β-catenin in resistant long APC-mutated CRC PDCs^[1].
RK-582 (0.3 μM; 24 h) induces AXIN1 accumulation without altering active β-catenin in APC-wild type CRC PDCs JC-11 and JC-494; at 3 μM, 24 h, it modulates MYC and E2F-related cell cycle regulators in these cells^[1].
RK-582 (0.001-10 μM; 5 days for proliferation assay; 3 μM, 48 h for WB) anti-proliferative effect on APC-wild type CRC PDC JC-11 is partially dependent on p21 induction, as siRNA-mediated p21 knockdown reduces RK-582's growth inhibitory activity^[1].
RK-582 (range; 10 min pre-incubation, 45 min reaction) potently inhibits human tankyrase-1 and tankyrase-2 catalytic activity, with ~504-fold selectivity over PARP1, ~34-fold selectivity over PARP2, and ~223-fold selectivity over PARP10^[2].
RK-582 (range) potently inhibits Wnt/β-catenin signaling in HEK293 and DLD-1 cells, with stronger activity in HEK293 cells^[2].
RK-582 (range; 4 days) potently inhibits the growth of COLO-320DM human colorectal cancer cells with a half-maximal growth inhibition concentration of 0.23 μM^[2].
RK-582 (range; 5 days) potently inhibits the proliferation of β-catenin-dependent COLO-320DM colorectal cancer cells (GI₅₀ = 0.035 μM) but does not affect β-catenin-independent RKO cells^[2].
RK-582 (0.1 μM; 16 h) modulates Wnt/β-catenin signaling in COLO-320DM cells by stabilizing AXIN2, reducing active β-catenin, and preventing tankyrase degradation^[2].
RK-582 (1 mM; 7 days soaking) binds to human TNKS2 via multiple specific interactions within the nicotinamide binding pocket, with the 2,6-dimethylmorpholine group oriented toward the cytosolic space^[2].

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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.5 mg/mL (4.90 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (4.90 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
