Abstract |
To reveal an essential biological role of menaquinone-4, we have clarified that dietary PK was converted to menaquinone-4 (MK-4) in animal tissues using deuterated vitamin K analogues. However, the kinds of analogue converted into MK-4 have not been elucidated. In this study, we examined structure-activity relationships in the conversion of several vitamin K analogues, with a substituted side chain, into MK-4 using cultured human cell lines. The results differed with the side chain of the analogues, that is, (1) the length of the isoprene unit and (2) the number of double bonds in the side chain. These findings would be useful for clarifying the mechanism of conversion of other vitamin K homologs into MK-4 as well as related enzymes.
