ASN007 inhibits the phosphorylation of ERK1/2 substrates such as RSK1, FRA1, and Elk1 in various cell lines[1].
ASN007 showes single-digit nanomolar antiproliferative activity that is selective for MAPK-pathway dependent cancer cell lines[1].
ASN007 (0.0005-10 µM, 60 min) can selectively inhibit ERK1/ERK2 enzymes (IC50 = 2 nM)[2].
ASN007 (4 h) dose dependently inhibits RSK1 (Ser380) phosphorylation in HT-29 cells[2].
ASN007 (15 min-72 h) rapidly (15 minutes) and persistently (72 hours) inhibits p-MSK1 and p-RSK1 in HT-29 cells[2].
ASN007 (0.0005-10 µM, 72 h) is sensitive to RAS/RAF mutant cell lines (median IC50 = 37 nM)[2].

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.
