As the foundation of life, biological molecules are the building blocks of our world. However, the same structure can lead to different functions or chemical properties. Diastereomers, a pair of molecules with the same chemical structure but different spatial arrangements of their atoms, hold the key to unlocking the full potential of these molecules.
Understanding Diastereomers
Diastereomers are more than just a scientific concept. They can have a significant impact on the properties and functions of molecules. For instance, the cancer drug doxorubicin can have heart-damaging side effects in a small percentage of patients. However, a diastereomer of the drug, known as epirubicin, which has a single alcohol group that points in a different direction, is much less toxic to heart cells.
- Examples of diastereomers in medicinal chemistry include:
- doxorubicin and epirubicin (the difference in toxicity)
- Aspirin and salicylic acid (differing in analgesic and anti-inflammatory properties)
- Micronutrient imbalances can lead to various health issues, including deficiencies in iron, calcium, or vitamin D.
The Potential of Diastereomers
Researchers like Alison Wendlandt, an associate professor of chemistry at MIT, are working on developing new tools that can convert diastereomers into different forms. Her lab is focused on designing these tools, which can change a molecule into a different constitutional isomer — a molecule that has an atom or chemical group located in a different spot, even though it has the same chemical formula as the original.
- These tools can be used to create new drugs with improved efficacy or reduced side effects.
- They can also be used to convert molecules into their mirror images or isomers, which can have different chemical properties.
- Additionally, these tools can be used to create entirely new molecules that might be difficult or impossible to build using traditional chemical synthesis techniques.
The Challenges
The development of these tools is not without its challenges. For instance, the spatial arrangement of atoms in a molecule can be difficult to predict and control. Additionally, the energy input required to convert a molecule into its mirror image or isomer can be a significant challenge.
| Challenge | Example |
|---|---|
| Predicting and controlling the spatial arrangement of atoms in a molecule | The spatial arrangement of atoms in a molecule can be influenced by factors such as the size and shape of the molecule, as well as the presence of other molecules in the system. |
| Providing the energy input required to convert a molecule into its mirror image or isomer | The energy input required can be provided through the use of catalysts, such as photocatalysts, which convert captured light into energy. |
Converting Molecules
Since joining the MIT faculty in 2018, Wendlandt has worked on developing catalysts that can convert molecules into their mirror images or isomers. In 2022, she and her students developed a tool called a stereo-editor, which can alter the arrangement of chemical groups around a central atom known as a stereocenter.
“I love the way that molecules can be thought of as dynamic, rather than static, and how these new tools can allow us to think about molecules in a new way. It’s a really exciting time for chemistry, and I feel privileged to be a part of it.”

The Future of Chemistry
As Wendlandt continues to develop new tools and technologies, the possibilities for chemistry are endless. With the ability to convert molecules into their mirror images or isomers, researchers can create new drugs with improved efficacy or reduced side effects. They can also create entirely new molecules that might be difficult or impossible to build using traditional chemical synthesis techniques. This approach opens up a whole new world of possibilities for chemistry, where molecules can be thought of as dynamic structures, rather than static ones.
Conclusion
In conclusion, diastereomers hold the key to unlocking the full potential of molecules. By developing new tools that can convert diastereomers into different forms, researchers can create new drugs with improved efficacy or reduced side effects. The future of chemistry is bright, and the possibilities are endless.
