This was done on cells in a lab, not in people. It is a very early step.
This was only tested on cells in lab dishes.
The short version
Scientists built new compounds that slowed brain tumor cells grown in lab dishes.
What was studied. Researchers made a new set of linked compounds called pyrimidine nucleoside dimers. They tested them on human cancer cells in dishes, including two 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 lines, U-138 MG and U-251 MG, with normal human cells used for comparison.
What they found. Several of the compounds slowed cancer cell growth and did little harm to the normal cells. Dimers 7 and 15 worked best against the U-251 MG 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 cells. Their effect was as strong as, or stronger than, an older drug called 5FdU.
What this means, and what it doesn't
What it could mean: This is early lab work that points to a possible new way to slow 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 cell growth. The compounds seemed to block the cells from copying their DNA. They also held up well in fluid, which helps for future testing.
What it doesn't mean: This does not mean there is a new treatment. The work was done only on cells in dishes, not in people or even animals. It does not show the compounds are safe or helpful for a patient. It is not a cure, and it is many years away from everyday care.
