A cell permeable hydroxytricyclic derivative that acts as a specific and reversible inhibitor of transient receptor potential melastatin 4 (TRPM4) (IC50=20uM in HEK293 cells). Does not affect TRPM5 and cystic fibrosis transmembrane conductance regulators (CFTR) channels. Decreases the occurrence of early after depolarizations (EAD) and exhibits an anti-arrhythmic effect that is independent of the action of protein kinase A. Shown to abolishnMDA-induced burst firing in dopaminergic neurons. Does not affect K+ currents at ~10uM, but at higher concentration (~100uM) it reversibly reduces K+ currents.Formula:C14H10OMolecular Weight:194.2Solubility:DMSO (50mg/ml)Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
