Genetic Engineering
what are the Goal Drug Overview marami yun
- Specified desired effect
- Optimal administration route
- Minimal dosage and frequency
- Onset and duration
- Minimal side effects
- Efficient elimination
- Production ease and low cost
- Pharmaceutical elegance
- Stability in various conditions
- These qualities are sought out in drug
and dosage form design although not
completely attainable
What are Methods of Drug Discovery?
Screening
Molecular modification
testing a large number of compounds for biologic activity + bioassay
screening
altering known compounds to improve drug-like
properties
molecular modification
aims to create drugs that create/interfere target
specific biochemical pathways or mechanisms of disease;
Mechanism-based drug design
Is a prototype chemical compound that has a fundamental desired biologic or
pharmacologic activity.
Lead Compound
it may not possess all of the features desired, such as potency,
absorbability, solubility, low toxicity and so forth.
Lead Compound
Is an inactive compound that needs metabolic transformation within the body to
become an active, pharmacologically effective substance.
Prodrugs
can be strategically designed for improved properties such as
solubility, absorption, stability and prolonged release.
Prodrugs
This transformation/conversion is carried out by enzymes, involving biochemical
cleavage
Prodrugs
Prodrugs may be designed preferentially for?
Solubility
Absorption
Biostability
Prolonged release
Prospective drug substances must undergo preclinical testing for biologic activity to
assess their potential as useful therapeutic agents.
Biologic Characterization
Various scientists collaborate in studies involving?
- Pharmacology
- Drug metabolism
- Toxicity
Studies drugs, their properties, actions, and uses
Pharmacology
