Long-term pharmacokinetic and pharmacological evaluations of a novel indole-benzazepinone derivative on obese Type 2 diabetes mellitus

Abstract

Background: Owing to the chronic nature of Type 2 diabetes mellitus, antidiabetic drugs must have long-lasting efficacy. Compound 1 has a good inhibitory effect on acute hyperglycemia, but its long-term hypoglycemic effect has not been evaluated. Results: Preliminary prediction and in vitro experimental pharmacokinetic results support the use of compound 1 for long-term in vivo experiments. Long-term experiments demonstrated that compound 1 significantly reduces blood glucose, improves the oral glucose tolerance of obese mice and has a positive effect on body weight, free fatty acid, hepatocyte steatosis and inflammatory cell infiltration. Conclusion: These findings lay a good foundation for the further exploration and development of novel glycogen phosphorylase inhibitors.
