Classical Molecular Drug Targets

Classical molecular drug targets collectively refer to the four major classes of macromolecules—enzymes, G protein-coupled receptors, ion channels, and transporters—that constitute the primary focus for the majority of approved and experimental drugs[8][1]. These protein families are highly studied since their modulation can influence key biological processes such as metabolism, cell signaling, and ion transport, which in turn play central roles in various diseases. The term is generic and does not correspond to a specific protein or gene but rather groups a set of well-validated molecular entities that serve as the cornerstone of traditional pharmacology and drug development[8][1].
