Buloxibutid (E4616-GRP)

Buloxibutid (AT2 Agonist C21) is a selective agonist of angiotensin II type 2 receptor (AT2R) with a Ki value of 0.4 nM for the AT2 receptor and a Ki >10 µM for the AT1 receptor. Its treatment significantly reduces vascular remodelling, improves hemodynamics, and decreases pulmonary collagen deposition in the Sugen-Hypoxia model of pulmonary hypertension.
