An aminophenylthiazole that acts as an inhibitor of TMEM16A channel, a calcium-activated chloride channel (CaCC) (IC50=1.1uM). Fully blocks CaCC current in salivary gland cells at 10uM, but has very little effect in airway and intestinal cells, which is consistent with the observation of RNAi knock-down. Completely blocks chloride currents produced by TMEM16A Activator, Eact at 10uM. In addition, shown to block calcium-activated chloride channels in vascular smooth muscle cells, and relaxes murine and human blood vessels.
Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C.
