ML204 inhibits TRPC4β-mediated intracellular Ca2+ rise with an IC50 value of 0.96 μM (HEK293 cells) and exhibits 19-fold selectivity against muscarinic receptor-coupled TRPC6 channel activation[1].
ML204 blocks TRPC4β activity induced through either Gi/o stimulation by μ-opioid, 5HT1A serotonin, and M2 muscarinic receptors or Gq/11 stimulation by the endogenous M3-like muscarinic receptors[1].
ML204 blocks LPS-induced TRPC5 channel activity[3].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (11.05 mM); Clear solution
