Strategy for drug discovery and/or optimization in which structural modification of an existing drug provides a new drug with improved chemical and/or biological properties.
Note: Within the context of analogue-based drug discovery, three categories of drug analogues are recognized: Compounds possessing structural, chemical, and pharmacological similarities, termed "direct analogues" and sometimes referred to as "me-too" drugs; compounds possessing structural and often chemical but not pharmacological similarities, termed "structural analogues"; and structurally different compounds displaying similar pharmacological properties, termed "pharmacological analogues".
