New vitamin B12 therapy shows promise against deadly brain cancer

Researchers have developed a vitamin B12-based compound that can penetrate the blood-brain barrier and specifically target glioblastoma tumors. In animal studies, the compound accumulated preferentially in tumor tissue and delivered sustained nitric oxide directly to cancer cells, while also working synergistically with existing glioblastoma treatments to significantly enhance their effectiveness. This breakthrough approach addresses a major challenge in brain cancer treatment—delivering therapeutics across the protective blood-brain barrier—and offers potential for improving outcomes in patients with this highly aggressive malignancy. The findings represent an important step toward developing more effective combination therapies for glioblastoma.
