Study Notes
Prodrugs and Functional Groups
- Prodrugs are chemically modified drugs that increase absorption, solubility, or palatability.
- The main functional groups in prodrugs include amides, nitro groups, alcohols, esters, and acyl halides.
Metabolism and Enzymatic Action
- Metabolism of prodrugs often involves hydrolases, which act on the drug to convert it into active metabolites.
- Common products of drug metabolism can include alcohols, amides, and carboxylic acids.
Classification of Drugs
- Drugs categorized by their mechanisms include cell wall synthesis inhibitors, cell membrane disruptors, and nucleic acid synthesis inhibitors.
- Specific compounds may be linked to certain classes, such as anesthetics or analgesics.
Partition Coefficient and Drug Solubility
- The partition coefficient, crucial for understanding drug solubility, can be identified using compounds like n-octanol.
- Factors influencing absorption include the Noyes-Whitney equation and Fick's Law of Diffusion.
Metabolism of Specific Drugs
- Isoniazid undergoes acetylation primarily during its metabolism in humans.
- Assessing ligand-receptor interactions involves understanding affinity and intrinsic activity.
Strain in Molecular Structures
- Molecular strain types include angular strain, torsional strain, steric strain, and axial strain, impacting compound stability.
Antimicrobial Characteristics
- Certain compounds such as hydrogen peroxide are effective against aerobic microorganisms and exhibit good tissue penetrability.
- Polyene antifungals work by binding ergosterol, causing ion leakage and fungal death.
Chemical Reactions and Synthesis
- Freidles Craft Alkylation requires specific catalysts for aromatic reactions.
- Esters are synthesized using sulfuric acid as a catalyst.
Pharmacodynamics
- Cholestyramine is an example of chemical antagonism affecting drug absorption and distribution.
- Lipoxygenase enzyme inhibitors play a role in managing respiratory conditions.
Phenol Derivatives and Antiseptics
- Phenolic compounds possess varying solubility characteristics and exhibit activity spectrum against different organisms, including Gram-positive bacteria.
- Commonly used disinfectants and antiseptics are essential for infection control in clinical settings.
Cephalosporins and Antibiotic Development
- Second-generation cephalosporins like cefuroxime can effectively cross the blood-brain barrier, enhancing their therapeutic utility.
- Knowledge of penicillin's functional groups and modifications influences resistance and efficacy against bacterial infections.
Clinical Implications
- Drug interactions can lead to adverse effects like Redman syndrome, mostly seen with medications like vancomycin.
- Understanding the mechanisms of action for various antibiotics enhances treatment approaches for infections.
Routes of Administration
- Tigemonam and similar antibiotics may be administered via specific routes (e.g. IV, topical) depending on the formulation and targeted action.
- Preservatives in vaccines, such as thimerosal, ensure stability and minimize contamination risks.
