Unit 1
Medicinal Chemistry: Introduction, drugs – classification of drugs – mechanism of drug action. Drug-receptor complex nomenclature – agonist, antagonist.
Physicochemical properties in relation to biological action: solubility, partition coefficient, dissociation constant, hydrogen bonding, ionization, drug shape, surface activity, complexation, protein binding, molar refractivity, bioisosterism – Stereo chemical aspects of drug action-stereo isomerism-optical isomerism.
