1-EBIO Chemical Properties,Usage,Production

Description

1-EBIO is an activator of Ca2+-sensitive K+ channels (EC50 = 490 μM in T84 human carcinoma cells).This action is sensitive to the neurotoxin charybdotoxin (Ki = 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 Ca2+-activated K+ channel (EC50 = 74 μM).1-EBIO is currently used to study the role of these types of K+ channels in diverse physiological functions.

Uses

1-EBIO stimulates Cl- secretion in secretory epithelia through direct activation of clacium potassium channels.
1-EBIO was used to study the electrical activity modulated by Ca+2-activated K+ channels in rat central neurons. The effect of 1-EBIO on human intermediate conductance channels was studied.
The K+ channel opener 1-EBIO potentiates residual function of mutant CFTR in rectal biopsies from cystic fibrosis patients

Definition

ChEBI: 1-Ethyl-2-benzimidazolinone is a member of imidazoles.

Biological Activity

Activator of epithelial K Ca channels, stimulates a large and sustained trans-epithelial Cl - secretory response across T84 monolayers. Induces hyperpolarization to the same magnitude as ACh in aortic value endothelial cells.

Room temperature
