What is Medicinal Chemistry I?
Medicinal Chemistry I deals with the chemical basis of drug action, including how the structure, functional groups, stereochemistry, and physicochemical properties of drug molecules influence their activity.
It also covers structure–activity relationships (SARs), mechanisms of action, and the chemistry of important therapeutic drug classes.
These notes will help you understand topics like:
Drug Design & Development:
Lead compound discovery
Bioisosterism
Prodrugs
Physicochemical properties of drugs
Drug-receptor interactions
QSAR (Qualitative & Quantitative SAR)
Drug Metabolism:
Phase I & Phase II reactions
Enzymes involved in biotransformation
Oxidation, reduction, hydrolysis, conjugation reactions
Importance of metabolism in drug design
Drugs Acting on the Autonomic Nervous System:
Cholinergic drugs: agonists, antagonists, anticholinesterases
Adrenergic drugs: sympathomimetics, blockers
Ganglionic stimulants/blockers
Neuromuscular blockers
Includes structures, IUPAC names, SAR, and mechanisms
Drugs Acting on the Central Nervous System:
Sedatives & hypnotics
Antipsychotics
Antidepressants
Anticonvulsants
Analgesics
Detailed classification, SAR, and mechanisms for each category
Local Anesthetics:
Ester & amide anesthetics
Mechanism of nerve blockade
SAR: lipophilic group, intermediate chain, ionizable group
Diuretics:
Carbonic anhydrase inhibitors
Thiazides
Loop diuretics
Potassium-sparing diuretics
Includes SAR and chemical classes
