For cardiovascular diseases such as high blood pressure, angina pectoris, and left ventricle hypertrophy; long-term activation of beta-adrenergic receptors is strongly linked to the progression of these diseases. A class of antagonistic drugs that target betaadrenergic receptors are collectively called beta-blockers. These drugs are commonly used to reduce the inotropic and chronotropic effects of beta-adrenergic receptor activation. This past decade has revealed that beta-blockers and other ligands are capable of functional selectivity at receptors. Functional selectivity describes the ability of ligands acting at 0 protein-coupled receptors (OPCRs) to preferentially activate or inhibit different signal transduction pathways. The studies on beta-adrenergic …
