Presentation Abstract

Ascorbic Acid as a Novel Co-factor for Cytochrome P450 Metabolism and Cancer Cell Selectivity

Ascorbic acid can be viewed as a universal enzyme co-factor and more specifically as an enzyme co-factor for cancer cell selectivity. Ascorbic acid is an electron donor for cytochrome P-450 catalyzed metabolism of drugs and circulating substrates. This donation of electrons takes place not only in the lumen of the endoplasmic reticulum but also in the mitochondria. This leaves ascorbic acid as a central electron donor for cytochrome-P450 metabolism. The electron transfer from ascorbic acid to oxygen is an enzymatic process mediated by a cytochrome P450 isozyme. In the case of cancer that isozyme is CYP1B1. This represents a highly beneficial synergy between ascorbic acid and CYP1B1 that could be exploited to enhance patient recovery. Ascorbic acid acts as a co-factor for CYP1B1 metabolism. CYP1B1 provides the cancer cell selectivity, an organic diet provides the substrates that get transformed into compounds that can initiate apoptosis or inhibit further cell division, and ascorbic acid provides the electrons to facilitate this metabolism of dietary substrates by CYP1B1.  Through this mechanism we can view ascorbic acid as a co-factor for cancer cell selectivity. Case studies are presented to highlight the utility of this mechanism.
