Abstract In recent years vitamin B6 has become a focus of research describing the compound’s critical function in cellular metabolism and stress response. For many years the sole function of vitamin B6 was considered to be that of an enzymatic cofactor. However, recently it became clear that it is also a potent antioxidant that effectively quenches reactive oxygen species and is thus of high importance for cellular well-being. In view of the recent findings, the current review takes a look back and summarizes the discovery of vitamin B6 and the elucidation of its structure and biosynthetic pathways. It provides a detailed overview on vitamin B6 both as a cofactor and a protective compound. Besides these general characteristics of the vitamin, the review also outlines the current literature on vitamin B6 derivatives and elaborates on recent findings that provide new insights into transport and catabolism of the compound and on its impact on human health. 1- Introduction The Discovery of Vitamin B6 The formula of vitamin B6 (henceforth referred to as vitB6) was first published by Ohdake in 1932. He worked on the isolation from rice-polishings of what he called “Oryzanin” (Vitamin B1) and found vitB6 as a by-product [1, 2]. Ohdake described the formula, but he was not aware that he had found a vitamin and did not recognize its physiological importance. At this time several scientists worked on the characterization of the vitamin B family members [3- 10]. These scientists were searching for the so called “rat pellagra prevention factor” that could cure acrodyna, a pellagra-like skin disorder in rats. They discovered that by adding a special yeast eluate to the diet, acrodyna could be cured. Paul György, a Hungarian born scientist, first described vitB6 as the active “rat pellagra prevention factor” in the yeast eluate [3]. Several years later in 1938 five separate groups of researchers, including György, isolated the crystalline vitB6 from yeast [4-8]. After determination of the structure of vitB6 in 1939, György named the vitamin pyridoxine due to its structural homology to pyridine [9]. In the same year, Stanton A. Harris and Karl Folkers, accomplished the synthesis of vitB6 [10]. In further studies it was shown that vitB6 could exist in other chemical forms that differ from pyridoxine by a variable group present at the 4′ position [11]. Pyridoxine (PN) carries a hydroxyl, pyridoxal (PL) an aldehyde and pyridoxamine (PM) an amino group (Figure 1). While all three species can be phosphorylated, it is pyridoxal 5’-phosphate (PLP) that is the biologically most active form and used as cofactor for many important enzymatic reactions.. |
