-
Paragraph 0077-0079, (2020/04/17)
The present invention relates to nicotinamide riboside derivatives conjugated with fatty alcohol, and a composition for wrinkle reduction or antiaging comprising the same. The nicotinamide riboside derivatives conjugated with fatty alcohol according to the present invention have increased stability and body absorption, and hydrolyze in the body to supply NAD precursors, thereby being effectively used for cosmetic compositions, pharmaceutical compositions, and health functional foods for wrinkle reduction or antiaging.(AA) Comparative example compound (NR)(B2,B3) Time(BB) Compound of example 8(CC) Compound of example 7COPYRIGHT KIPO 2020
CONVENIENT SYNTHESIS OF ESTERS OF 2-PYRROLECARBOXYLIC ACID AND OF PYRIDINECARBOXYLIC ACIDS BY SOLID-LIQUID PHASE TRANSFER CATALYSIS WITHOUT ADDED SOLVENT

By reaction of aromatic K-carboxylates having nucleophilic N-atom in solid-liquid phase transfer catalysis (PTC) conditions without added solvent (catalyst : tetraalkylammonium halide) with alkylating reagents, the corresponding esters are prepared.By a judicious choice of experimental conditions, the amounts of N-alkylated products can be lowered.From 2-pyrrolecarboxylic acid, the three isomers of pyridinecarboxylic acid and o-aminobenzoic acid, corresponding esters of ethyl, benzyl, n-octyl and n-cetyl, generally are obtained with good yields.
