摘要:
The present invention relates to novel carboxylic acid-substituted idebenone derivatives, skin treatment compositions containing these carboxylic acid-substituted idebenone derivatives, methods of treating skin changes by topical application of these carboxylic acid-substituted idebenone derivatives, and their methods of synthesis. The carboxylic acid-substituted idebenone derivatives of the present invention are unexpectedly effective in treating skin, particularly with respect to skin tolerance. When included in a topical composition, the carboxylic acid-substituted idebenone derivatives of the present invention have an antioxidant effect that is useful in treating a skin change.
摘要:
A new method for the synthesis of L-Glutamyl-γ-D-Glutamic acid and its use in the synthesis of (2R)-((4S)-carboxy-4-(4,N-(((6S)-2-(hydroxymethyl)-4-oxo-3,4,7,8-tetrahydro-3H-cyclopenta[g]quinazolin-6-yl)-N-(prop-2-ynyl)amino)benzamido)butanamido)pentanedioic acid, 1 are provided. Also provided is an efficient method for the isolation and purification of the trisodium salt of the abovementioned acid, 2, in a form suitable for long term storage and use in a parenteral dosing form.
摘要:
A method of producing 6-amino-cyclopenta[g]quinazolines, in enantiomerically enriched form, is provided. In particular, the method may be applicable to the synthesis of N—{N-{4-[N-((6S)-2 -hydroxymethyl-4-oxo-3,4,7,8-tetrahydro-6H-cyclo-penta[g]quinazolin-6-yl)-N-(prop-2 -ynyl)amino]benzoyl}-L-γ-glutamyl}-D-glutamic acid (ONX-0801).
