Drug Target Types Flashcards
Ion Channels
Mechanism: Alter conductance
Examples: Local anesthetics - Lidocaine; Sedative-Hypnotics - Valium/Diazepam; Antiepileptics - Carbamazepine
G-Protein Linked Receptors
Mechanism: binding
Examples: B2 agonist - Albuterol (asthma); B antagonist - Propranolol (hypertension)
Enzyme-Linked Receptors
Mechanism: Receptor Tyrosine Kinase Family (cell growth & differentiation)
Examples: Insulin receptors, EGFR, Imatinib (leukemia)
Nuclear Receptors
Mechanism: Intracellular, regulate gene expression for metabolism & development
Examples: Steroid hormones - hydrocortisone cream, Thyroid hormones - Levothyroxine, Vitamin D
Enzymes
Mechanism: Inhibit enzyme activity
Examples: Aspirin, Ibuprofen, Omeprazole
Transporters
Mechanism: Neurotransmitter targets
Examples: Antidepressants - Prozac
Structural Proteins
Mechanism: Tubulin binding prevents metaphase arrest & polymerization
Examples: Anticancer drugs - Vinblastine
Non-Binding to molecular components
Antacids (neutralize gastric acid)
