This was done in animals, not people. Most findings at this stage never become treatments.
This was only tested in lab cells and in mice.
The short version
Scientists built two new compounds that killed brain tumor cells in the lab and slowed tumors in mice.
What was studied. Chemists made a pair of mirror-image compounds called S-CAT6 and R-CAT6. They tested them on glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary cells, including cells that resist the drug temozolomide: A chemotherapy taken as a capsule, used for some brain tumors. Your team checks your blood counts while you are on it. See the glossary, and then tested S-CAT6 in mice carrying human tumor cells.
What they found. Both compounds killed glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary cells, even cells that no longer respond to temozolomide: A chemotherapy taken as a capsule, used for some brain tumors. Your team checks your blood counts while you are on it. See the glossary. The S form worked better than the R form, and it caused less harm to the stomach and gut. In the mice, S-CAT6 worked better against the tumors and looked safe.
What this means, and what it doesn't
What it could mean: This is early chemistry work on a possible future drug. The results hint that this kind of compound might help when temozolomide: A chemotherapy taken as a capsule, used for some brain tumors. Your team checks your blood counts while you are on it. See the glossary stops working. No person has taken it yet, so there is nothing a patient can ask a doctor for today.
What it doesn't mean: This does not mean a new treatment is coming soon. The work was done in cells in a dish and in mice, not in people. Many compounds that work in mice never work in humans. It is not a cure, and it is years away from everyday care, if it ever gets there.
