Study Notes
Purpose of SAR Studies
- Studying the Structure Activity Relationship (SAR) in medicinal chemistry is crucial for understanding how the chemical structure of a drug influences its biological activity.
- This knowledge helps in:
- Designing new drugs with improved efficacy and reduced side effects
- Optimizing existing drugs for better performance
- Developing drugs that target specific biological pathways
Pharmacophore in Drug Molecules
- The pharmacophore is a collection of structural features (functional groups, atoms) that are essential for a drug molecule's ability to bind to its biological target.
- It's the minimum structural requirement for a drug to have its desired pharmacological effect
First Pass Effect and Drug Metabolism
- The first-pass effect describes the metabolism of a drug in the liver before it even reaches systemic circulation.
- This process can significantly reduce the amount of active drug reaching its target, therefore impacting the drug's efficacy
- Drugs undergoing extensive first-pass metabolism may require higher doses or alternative delivery routes to achieve the desired therapeutic effect
Factors Influencing Drug Activity
- Several factors can influence drug activity, including:
- Chemical structure
- Physicochemical properties (e.g., solubility, lipophilicity)
- Binding affinity to target
- Metabolism
- Distribution in the body
- While these factors are all important, the least likely to influence drug activity is the drug's color.
Intrinsic Activity in Pharmacodynamics
- Intrinsic activity refers to the ability of a drug to activate its target receptor after binding.
- It's a measure of a drug's ability to elicit a maximal response.
- Drugs with high intrinsic activity are very effective at activating their target, while drugs with low intrinsic activity are less effective.
Formative Quizzes in Medicinal Chemistry
- Formative quizzes are designed to assess student understanding of the course material.
- They are a way to monitor progress and identify areas where additional explanation is needed.
Focus of Medicinal Chemistry
- Medicinal chemistry studies the design, synthesis, and development of new drug molecules.
- It focuses on:
- Understanding the relationship between a drug's structure and its biological activity
- Identifying and synthesizing novel drug candidates
- Optimizing existing drugs for improved efficacy, safety, and pharmacokinetic properties
- Marketing strategies are not a main focus of medicinal chemistry.
Final Exam's Contribution to Total Assessment
- The final exam typically contributes a significant proportion of the total assessment, allowing students to demonstrate their comprehensive understanding of the course content.
Personal/Team-Based Learning and Assessment
- Personal/Team-Based Learning (TBL) emphasizes the importance of teamwork and active learning.
- It assesses collaborative learning, problem-solving skills, and the ability to communicate scientific information effectively.
ADME in Drug Development
- In drug development, 'ADME' stands for Absorption, Distribution, Metabolism, and Excretion.
- This refers to how a drug is taken up into the body, where it travels, how it is broken down, and how it's eliminated.
- ADME studies are crucial for predicting the fate of a drug in the body and optimizing its pharmacokinetic properties.
