Natural Products Synthetic Chemistry Lab
Machine-translated · View original
The lab uses organic synthesis to build, in full, natural products with powerful biological activity.

AboutAbout the lab
Science that grows out of the total synthesis of bioactive natural products
The Natural Products Synthetic Chemistry Lab studies total synthesis, the use of organic synthesis to build in full natural products that act strongly on the body.
Its targets are natural products densely packed with polar functional groups, and large peptide-based natural products that may function like proteins.
Even today, there is no established method for the total synthesis of such natural products. The lab develops new reactions, synthetic methods, and strategies for this purpose.
The lab also aims to create new functional molecules with properties not found in natural products, as well as miniaturized proteins.
Key terms
- Total synthesis
- Artificially assembling a complex molecule, such as a natural product, from simple starting materials through a series of chemical reactions
- Polar functional group
- A group of atoms, such as a hydroxyl group, with an uneven distribution of electric charge that determines a molecule's properties and function
- Peptide
- A molecule in which amino acids are linked in a chain. When the chain becomes long, it forms a protein

ResearchResearch themes
The lab works on science that grows out of the total synthesis of bioactive natural products. It develops reactions, synthetic methods, and strategies that make the total synthesis of highly functional natural products broadly applicable, and aims to create new functional molecules based on natural products.
*Illustrative imageNatural products as the foundation of the research
The research is built on natural products densely packed with polar functional groups that act strongly on proteins and other targets, and on large peptide-based natural products. Although natural product molecules are small, their diverse ring structures and functional groups pack in a great deal of information about their activity.
*Illustrative imageTotal synthesis: recreating a natural product in full
Natural product structures are economical, and losing even a part of one often greatly reduces its activity. To use natural products in medicines and similar applications, total synthesis that completely reproduces the three-dimensional arrangement of atoms is necessary.
*Illustrative imageTotal synthesis methods and new functional molecules
To make the total synthesis of highly functional natural products broadly applicable, the lab develops reactions, synthetic methods, and strategies. Using synthetic organic chemistry that freely controls three-dimensional structure, it aims to create new functional molecules with properties not found in natural products, as well as miniaturized proteins.
