3-[(5-CHLORO-2-HYDROXYPHENYL)METHYL]-5-[4-(TRIFLUOROMETHYL)PHENYL]-1,3,4-OXADIAZOL-2(3H)-ONE Chemical Properties,Uses,Production

Description

BMS 191011 is an activator of large-conductance calcium-activated potassium (KCa1.1/BK) channels that increases maximum potassium current to 126% of control in X. laevis oocytes expressing human KCa1.1 channels when used at a concentration of 1 μM. In vivo, BMS 191011 (10-100 μg/kg, i.v.) increases the diameter of retinal arterioles without affecting blood pressure or heart rate in rats, an effect that is reversed by the KCa1.1 channel blocker iberiotoxin .

Uses

BMS 191011, is a potent opener of the large-conductance, Ca2+-activated potassium (maxi-K) channel. It has also shown neuroprotective properties in two distinct animal models of stroke- MCAO in the SHR rat and a normotensive model of focal stroke.

Definition

ChEBI: 3-[(5-chloro-2-hydroxyphenyl)methyl]-5-[4-(trifluoromethyl)phenyl]-1,3,4-oxadiazol-2-one is a member of (trifluoromethyl)benzenes.

Biological Activity

Potent Maxi-K channel opener (large-conductance Ca 2+ -activated potassium channel, K Ca 1.1, BK Ca ). Neuroprotectant in two distinct animal models of stroke (MCAO in the SHR rat and a normotensive model of focal stroke).
