New 2-methyl-1,4-naphthoquinone derivatives with vitamin K activity are provided having the general formula (1): wherein R is a aliphatic group with 12 to 50 carbon atoms. Preferably, R is a straight or branched C12-50 alkylgroup or a straight or branched C12-50 alkenyl group with 1 to 12 unsaturated bonds. Of these, the compound of formula (1) in which R is a straight C14 alkyl group is most preferred. Pharmaceutical and nutraceutical compositions comprising at least one compound of formula (1) or a pharmacologically active precursor there of are also provided.

Synthesis and self-assembling properties on gold of 2-methyl-1,4-naphthoquinone derivatives containing ω-mercaptoalkylalkanoate groups
The synthesis of a series of 2-methyl-1,4-naphthoquinone (2-MeNQ) derivatives containing surface active ω-mercaptoalkylalkanoate groups with 5–12 atoms in the side-chains is reported. The compounds form stable self-assembled monolayers (SAMs) on gold. The complete reduction of the terminal 2-MeNQ group in the SAMs was confirmed by in situ Fourier-transform surface-enhanced Raman spectroscopy (FT-SERS)
