- Tested in people
This was done on cells in a lab, not in people. It is a very early step.
This was only done on cells in a dish and in computer models.
The short version
Scientists changed an anti-inflammatory drug and tested it on cancer cells in a lab, not in people.
What was studied. Researchers made a new set of compounds based on nimesulide, an anti-inflammatory drug. They tested the compounds on cancer cells grown in the lab and used computer models to study how one compound fits an enzyme called MetAP2.
What they found. One compound, called 3i, killed cells from several breast cancer lines. After 72 hours, most of the treated cells had switched from living to dying. The effect was strongest in triple negative breast cancer cells. Compound 3i also blocked the MetAP2 enzyme, and computer models showed it stayed bound to that enzyme.
What this means, and what it doesn't
What it could mean: This is very early lab work. Nothing here was tested in people, and no one with a brain tumor took this compound. The authors only suggest that these compounds might one day be worth studying for cancers including glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary. It is an idea for future research, not a treatment you can ask for.
What it doesn't mean: This does not mean a new brain tumor drug exists. The work was done on cells in a dish and on a computer, not in people or even in animals. The cancer cells tested were breast cancer cells, not brain tumor cells. Years of further testing would be needed before anyone knows if this is safe or helpful. This is not a cure, and it is not a promise of one. Do not change your care or take nimesulide based on this study.
