Abstract
Propranolol is a widely used quality control and validation compound for liver microsome and hepatocyte metabolism studies. A multitude of literature reports describing the identification of propranolol metabolites exists today. However, no literature reports currently exist showing hepatocyte metabolism across the five species commonly used during pre-clinical drug discovery, namely mouse, rat, dog, monkey, and human. Herein, we present full metabolic profiles of propranolol in mouse, rat, dog, monkey and human hepatocytes. As expected, extensive phase I and phase II metabolism was observed across all five species and species-specific metabolites were detected in monkey and dog hepatocytes. Of particular interest was the detection of an N-hydroxylamine glucuronide metabolite in monkey and dog hepatocytes.
