Carboetomidate: a pyrrole analog of etomidate designed not to suppress adrenocortical function.

ABSTRACT:

Background

Etomidate is a sedative hypnotic that is often used in critically ill patients because it provides superior hemodynamic stability. However, it also binds with high affinity to 11beta-hydroxylase, potently suppressing the synthesis of steroids by the adrenal gland that are necessary for survival. The authors report the results of studies to define the pharmacology of (R)-ethyl 1-(1-phenylethyl)-1H-pyrrole-2-carboxylate (carboetomidate), a pyrrole analog of etomidate specifically designed not to bind with high affinity to 11beta-hydroxylase.

Methods

The hypnotic potency of carboetomidate was defined in tadpoles and rats using loss of righting reflex assays. Its ability to enhance wild-type alpha1beta2gamma2l and etomidate-insensitive mutant alpha1beta2M286Wgamma2l h
