Researchers at Northwestern University solved a long-standing mystery about two molecules in rye pollen. These molecules could help slow down tumor growth and lead to new cancer treatments.

Thirty years ago, scientists discovered two unusual molecules in rye pollen that seemed to slow down tumor growth in animal studies. However, they couldn't figure out the exact shape of these molecules. This made it hard for other researchers to understand how they work and use them to develop new cancer treatments.

A team of chemists at Northwestern University finally solved this mystery by building the molecules from scratch in the lab. They used a process called total synthesis, where they created each part of the molecule step by step. This was a difficult task because the molecules have a very rare and tightly compressed structure.

The researchers confirmed that the molecules are secalosides A and B. With their exact shape now known, scientists can study how these compounds interact with the immune system. This knowledge could help develop new approaches to cancer treatment. Karl Scheidt, the lead researcher, said,
