This cancer-fighting molecule took 50 years to build

MIT chemists successfully synthesized verticillin A, a cancer-fighting fungal molecule first discovered in 1970 but too complex to recreate in labs until now. The compound's intricate structure, featuring just two additional oxygen atoms compared to a related molecule, made it extremely fragile and challenging to build through traditional methods. Researchers had to completely redesign their approach, developing a 16-step process that carefully controls the molecule's delicate chemistry. Early tests show promising results against pediatric brain cancer, particularly diffuse midline glioma.
