Technical Support

AR-42 (HDAC-42; OSU-HDAC42) is a potent, orally bioavailable pan-HDAC inhibitor (IC₅₀=16 nM). AR-42 induces growth inhibition, cell-cycle arrest, apoptosis, and activation of caspases-3/7. AR-42 promotes hyperacetylation of H3, H4, and alpha-tubulin, and up-regulation of p21. AR-42 shows cytotoxicity against various human cancer cell lines.

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.

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.
