BQ-788, a selective endothelin (ET) B-receptor antagonist, was developed by Banyu. This compound is widely used to demonstrate the role of ET-1 and ET(B) receptor subtypes in physiological and/or pathophysiological conditions. BQ-788 was studied against hypertension. However, this study was discontinued. Besides, was shown that BQ788 could protect against brain edema by inhibiting vascular endothelial growth factor-A-mediated decrease in claudin-5. The intralesional applications of BQ788 were well tolerated and showed signs of directly and indirectly reducing the viability of melanoma cells.
