Eact activates the Calcium-activated Chloride channel (CaCC) TMEM16A CaCC. Eact stimulates CaCC conductance in salivary gland cells and submucosal airway epithelial cells. The compound Eact also stimulates submucosal gland secretion in human bronchial tissue and smooth muscle contraction in mouse intestine.
In rat arterial myocytes, Eact [3,4,5-trimethoxy-N-(2-methoxyethyl)-N-(4-phenyl-2-thiazolyl)benzamide] helps to activate chloride current and prevents estradiol synthesis in cultured mouse granulosa cells. It is a small molecule activator of TMEM16A (transmembrane member 16A), that activates TRPV1 (transient receptor potential cation channel subfamily V member 1) and generates pain and itch related symptoms. Eact also initiates endogenous TRPV1 expressed by DRG (dorsal root ganglion) neurons.
