Description

[0001] field of invention [0002] The present invention relates to a GLP-1 receptor agonist compound, a salt thereof, or a solvate of the compound or the salt of the compound, which has an action similar to that of GLP-1. The present invention further relates to a preventive or therapeutic agent for non-insulin-dependent diabetes (type 2 diabetes) or obesity comprising the compound, salt or solvate as an active ingredient. Background technique [0003] Glucagon-like peptide-1 (GLP-1) is an incretin secreted by L cells of the small intestine when nutrients pass through the digestive tract, and GLP-1 is known to exhibit various actions through the GLP-1 receptor, such as Promote glucose-dependent insulin secretion, inhibit glucagon secretion, delay gastric emptying, and inhibit food intake. Although GLP-1 analogs have been commercialized as diabetes therapeutics and are regarded as one of the most effective diabetes therapeutics due to their potent effects of HbA1c lowering an...
