Biological target:
ML 190 is a selective κ opioid receptor (KOP) antagonist (IC50 = 120 nM in a β-arrestin assay).
In vitro activity:
The results demonstrate that NF-κB/p65 nuclear translocation was significantly attenuated following treatment with DYN 1-17 and a specific range of fragments, with the greatest reduction observed with DYN 1-7 at a low concentration (10 nM). Antagonism with a selective KOP receptor antagonist, ML-190, significantly reversed the inhibitory effects of DYN 1-17, DYN 1-6, DYN 1-7 and DYN 1-9, but not other DYN 1-17 N-terminal fragments (DYN 1-10 and 1-11) on NF-κB/p65 nuclear translocation.

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.

Preparing Stock Solutions

The following data is based on the product molecular weight 488.59 Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.
