In Vitro

XX-650-23 (870 nM-2.3 μM; 48 hours) inhibits AML cell growth, the IC₅₀ values are 870 nM, 910 nM, 2.0 μM and 2.3 μM for HL-60, KG-1, MOLM-13, and MV-4-11,respectively^[1].
XX-650-23( 5 μM; 6 or 24 hours) causes a specific decrease in H3K27 acetylation and is not a general inhibitor of acetyltransferase activity^[1].
XX-650-23 (2 μM; 72 hours) elicits apoptosis through the intrinsic apoptosis pathway, with activation of caspase-3 and detectable caspase-9 cleavage. It also leads to the downregulation of Mcl-1 and bcl-2^[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

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 90% Corn Oil
Solubility: 2.5 mg/mL (8.67 mM); Clear solution; Need ultrasonic

This protocol yields a clear solution of 2.5 mg/mL. 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.

Calculation results:

Working solution concentration: mg/mL

Method for preparing stock solution: mg drug dissolved in μL DMSO (Stock solution concentration: mg/mL).

The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.

If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
