The present invention relates to a sesamol derivative or its salt, and a skin external composition containing the same. More particularly, the invention relates to a sesamol derivative or its salt, which consists of sesamol and 3-aminopropane phosphoric acid, linked with each other by a phosphoric acid diester bond, and can be degraded into sesamol and 3-aminopropane phosphoric acid by enzymes present on the skin so as to simultaneously show the physiological activities of sesamol and 3-aminopropane phosphoric acid, as well as a preparation method thereof and a skin external composition containing the same.

This invention concerns isotopically coded or non-isotopically coded affinity-tags for analysis of certain target molecules in complex samples, in particular for mass spectrometric analysis of proteomic samples. The affinity-tags have the following general formula X-SPACER-OPO
3
H
2
, wherein X is a functional group or moiety capable of reacting with a functional group of a protein, peptide, DNA, lipid, sugar and/or steroid. These phosphate affinity tags (‘PTAG’) are capable of high but reversible binding to metal-oxides like TiO
2
. Due to this property, tagged sample fractions can be isolated from non-tagged sample fraction by affinity chromatography. The binding of organophosphate to metal-oxides remains intact during multiple washings of preferably acidic solutions to remove non-specifically bound components. PTAG's are also envisaged wherein X is selected such that it is capable of binding proteins, peptides, nucleic acid molecules, lipids, carbohydrates, steroids and the like.

2 equivalents of NaOH. The rates of scission of the phosphoric monoester group and occasionally of the phenylcarbamoylamino group of these monoesters have been studied at 100°, in solutions 0.1M in ester and at various pH.
N-芳基(或芳烷基或烷基)氨基甲酰基-氨基烷基磷酸单酯已通过在2当量的NaOH存在下,异氰酸酯R'-NCO与相应的氨基烷基磷酸单酯H 2 NROPO 3 H 2进行反应制备。已经在100°,在酯中的0.1M溶液中以及在各种pH下研究了这些单酯的磷酸单酯基的断裂速率,偶尔还发现了苯基氨基甲酰氨基的断裂速率。
