Many hypertension medications currently on the market target the AT1 receptor because of its well-understood role in blood pressure regulation; they block AT1 in order to reduce blood pressure. The AT2 receptor, on the other hand, is still an elusive drug target despite multiple studies of its function. Now, researchers have solved its structure to hone in on its function. The results of the experiments were surprising in several ways. First, although both compounds were designed to block and deactivate the receptors, they left AT2 in a state that appeared to be active. In addition, although AT1 and AT2 were thought to be very similar, the pockets where the receptors bind to the compounds exhibited marked differences.
