- Involucrin gene expression promoter
-
PROBLEM TO BE SOLVED: To provide an involucrin gene expression promoter that has high effect of promoting involucrin gene expression, and is applied to the skin, to quickly increase involucrin concentrations, and markedly improving the barrier function. SOLUTION: An involucrin gene expression promoter contains at least one selected from a compound represented by the following formula (1) [where R1 and R2 are the same or different to represent a hydrogen atom, or a substituent. n is an integer of 1 or greater], a salt thereof, and their hydrates as an active ingredient.

- PHOSPHORUS-CONTAINING AMINOCARBOXYLIC ACIDS. COMMUNICATION IV. A CONVENIENT METHOD OF PHOSPHONIC ACIDS SYNTHESIS
-
The communication is concerned with the synthesis of phosphonic aminocarboxylic acids by phosphorylation of diethyl ω-halogen alkyl acetamidomalonates with tris(trimethylsilyl) phosphite, followed by alcoholysis and acid hydrolysis of the resulting intermediate esters.Key words: Phosphonic aminocarboxylic acids; tris(trimethylsilyl) phosphite; ω-halogenalkyl acetamidomalonates; phosphorylation; alcoholysis, hydrolysis

- SYNTHESE D'ACIDES ω-AMINO-ω-CARBOXY-ALKYLPHOSPHONIQUES
-
ω-Amino ω-carboxyalkylphosphonic acids 1 synthesis is reviewed.For n = 4, 5, 6 a general, efficient and inexpensive synthesis is described; acetamido(ω-bromoalkyl)malonates 12 are prepared from commercial dibromoalkanes and acetamidomalonate using the phase transfer catalysis process, then condensed with triethylphosphite through an Arbuzov reaction.An acid hydrolysis followed by purification on Dowex gives aminophosphonic acids 1 (n = 4, 5, 6) with a 70percent overall yield.The lower acid 1 (n = 2) is obtained with an identical overall yield from acetamidomalonate and 2-haloethylphosphonate using also liquid-solid phase transfer catalysis.
