Drug-receptor thermodynamics

In thermodynamics, drug-receptor thermodynamics is the study of the entropy, enthalpy, free energy aspects of drug-receptor interactions. [1] Topics in this field include free energy maps, enthalpy-entropy compensation, heat capacity in ligand-receptor interactions, among other topics. [2] Pioneers in this newly developing field include Americans chemist Irvin Klotz, author of the 1997 Ligand-Receptor Energetics, and pharmacological engineer Robert Raffa, general editor of the first textbook on the subject, 2001 Drug-Receptor Thermodynamics, originally published as 1980 paperback. The subject of the thermodynamics or free energy aspects of drug-receptor interactions and dynamics began to arise in the late 1970s.

Some of the concepts in Raffa’s 2001 Drug-Receptor Thermodynamics were used by American chemical engineer Libb Thims as base models in the synthesis of the free energy interaction theories, e.g. "human molecular mechanisms", in the dynamics and life movements involved in human molecular interactions, i.e. interactions between people.
