Study Notes
Rigidification
- Rigidification is a strategy for modifying a drug molecule by introducing rings or rigid functional groups.
- Rigidification locks bonds within ring systems, preventing free rotation.
- This strategy aims to test rigid structures to identify those that retain the active conformation of the original molecule.
- Flexible molecules can have multiple conformations, which can lead to interactions with multiple target binding sites.
- Rigidification aims to limit conformations, increasing the likelihood of the desired active conformation being present.
- Rigidification increases selectivity by reducing the chance of undesired active conformations.
- Rigidification can lead to a more complex molecule, which may be more challenging to synthesize.
Disadvantages of Rigidification
- Oversimplification can decrease activity and selectivity.
- Simpler molecules have more conformations which can increase the likelihood of interacting with more than one target binding site.
- This leads to increased side effects.
Disadvantages of Simplification
- Oversimplification may result in decreased activity and selectivity.
- Simpler molecules have more conformations and are likely to interact with more than one target binding site.
- Simplification can result in increased side effects.
