The hormone glucagon increases blood glucose levels through increasing hepatic glucose output. In diabetic patients, dysregulation of glucagon secretion contributes to hyperglycemia. Thus, the inhibition of glucagon receptor is one target for the treatment of hyperglycemia in type 2 diabetes. Here we designed and synthesized a series of small molecules based on phenylpyrimidine. Of these, the compound (R)-7a most significantly decreased the glucagon-induced cAMP production and glucagon-induced glucose production during in vitro and in vivo assays. In addition, (R)-7a showed good efficacy in glucagon challenge tests and lowered blood glucose levels in diabetic db/db mice. Our results suggest that the compound (R)-7a could be a potential glucose-lowering agent for treating type 2 diabetes.

Semaglutide, sold under the brand names of Ozempic, Rybelsus and Wegovy, is one of the most popular drugs on the market. Manufactured by Novo Nordisk, semaglutide is the newest in a family of glucagon-like peptide-1 receptor agonists used most commonly to treat type II diabetes. To date, the results of semaglutide for the treatment of type II diabetes have been overwhelmingly positive.

Background: The use of glucagon-like-peptide-1 receptor agonists (GLP-1RAs) has greatly increased in patients of reproductive age within the past four years. However, there is minimal research into the long-term impact of these medications on future pregnancies.
Objectives: We aimed to evaluate the association between adverse obstetric outcomes and antecedent GLP-1RA use using a nationally representative database.

Semaglutide and liraglutide are long-acting glucagon-like peptide-1 receptor agonists used to treat type-2 diabetes and obesity. Recent advances in peptide synthesis and analytical technologies have enabled the development of synthetic generic peptide for reference listed drugs (RLD) originating from recombinant DNA (rDNA) technology. Since the original semaglutide and liraglutide were produced through rDNA technology, there has been great interest in developing their synthetic peptides as generic versions of the original drugs.

Obesity is a chronic condition that causes significant morbidity and mortality in people in the United States and around the world. Traditional means of weight loss include diet, exercise, behavioral modifications, and surgery. New weight loss medications, glucagon-like peptide-1 receptor agonists, are revolutionizing the management of weight loss but have implications for fertility and pregnancy.
