Biological target:
ML228 (CID-46742353) is a potent the Hypoxia Inducible Factor (HIF) pathway activator with EC50 of 1 μM.
In vitro activity:
The probe compound ML228 was among the top active compounds in each of the three HIF-specific activity assays and was inactive in the proteasome inhibition counterscreen assay (Figure 3). ML228 was found to inhibit greater than 75% of radioligand binding in six assays when tested at a concentration of 10 μM (Table 5). Reference: Bioorg Med Chem Lett. 2012 Jan 1;22(1):76-81. https://pubmed.ncbi.nlm.nih.gov/22172704/
In vivo activity:
A total of 90 12-week-old Sprague Dawley rats were randomly divided into the following three groups: Sham group (operation without SCI (spinal cord injury)); control group (SCI without ML228 treatment); and treatment group (SCI receiving ML228 treatment). The results of the current study suggest that ML228 may effectively activate the HIF-1α/VEGF signaling pathway to promote the expression of HIF-1α and VEGF proteins within the injured segment of the spinal cord, which promotes neural functional recovery following SCI in rats. Therefore, treatment with ML228 may be developed as a novel therapeutic strategy to treat SCI. Reference: Exp Ther Med. 2017 Mar;13(3):861-866. https://pubmed.ncbi.nlm.nih.gov/28450910/

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
