BQ-123 is a selective endothelin receptor-1 antagonist; it is used as a biochemical tool in the study of endothelin receptor function. BQ-123 was suspected to contribute to the regulation of vascular tone humans. However, a study involving young normotensive subjects did not demonstrate any major role for BQ-123 regulation of vascular tone.
