CGP-42112 is primarily utilized in research settings to study the angiotensin II receptor system, particularly its role in cardiovascular and renal functions. It acts as a selective ligand for the AT2 receptor subtype, helping to elucidate the receptor's physiological and pathological roles. This compound is valuable in experimental models to investigate mechanisms underlying blood pressure regulation, vascular remodeling, and tissue repair. Additionally, CGP-42112 is used to explore potential therapeutic applications targeting the AT2 receptor, such as in conditions like hypertension, heart failure, and kidney disease. Its specificity makes it a critical tool for understanding receptor signaling pathways and developing targeted treatments.
