1-EBIO (Synonyms:1-Ethyl-2-benzimidazolinone;1-乙基-1H-苯并[d]咪唑-2(3H)-酮)
目录号 : KCM10019 CAS No. : 10045-45-1 纯度 : ≥98%
1-EBIO is an activator of Ca-sensitive K channels (EC = 490 µM in T84 human carcinoma cells). This action is sensitive to the neurotoxin charybdotoxin (K = 3.5 nM). In mouse colonic epithelia, 1-EBIO also activates cAMP-sensitive K channels, a response this is inhibited by 293B. In this type of epithelium, but not mouse nasal epithelia, 1-EBIO activates both types of channels, resulting in large Cl- secretory currents. It also activates the human intermediate conductance Ca-activated K channel (EC = 74 µM). 1-EBIO is currently used to study the role of these types of K channels in diverse physiological functions.

生物活性

1-EBIO (1-Ethyl-2-benzimidazolinone) is an activator of Ca2+ sensitive K+ channels wirh an EC50 of 136 μM for KCa3.1. 1-EBIO induces Cl- secretion, K+ conductance, membrane hyperpolarization, and afterhyperpolarisation currents. 1-EBIO reduces epileptiform activity, seizure incidence, and rescues cells from Ionomycin induced death.
