Palmitoyl ascorbate (PA) is a strong anti-oxidant, is anti-angiogenic (reduces the formation of new blood vessels) and is the lipid-soluble form of Vitamin C. There are many ways these properties are useful and it is likely that PA can be useful in combatting all cancers. The article ‘Acylhomoserine lactone’ on this site explains in more detail its action as it builds up the ascorbate concentration in the host cells to combat invasive tumours. The effect of reduction in the formation of new blood vessels by an active tumour is also useful in slowing tumour development.

Recent work with cell cultures at the University of Central Lancashire has shown that palmitoyl ascorbate can wipe out glioblastoma cells in vitro. Glioblastoma is the most aggressive form of brain tumour and often found in young children. If this could be slowed down or stopped by a substance taken by mouth it might mean less or no surgery and a greatly improved recovery rate from this devastating condition. The work needs to be taken up by a University equipped for animal testing of the substance.
