molecules with novel skeletons, but also to identify the enzymes that catalyze diverse chemical reactions. Exploring the substrate promiscuity and catalytic mechanism of those biosynthetic enzymes facilitates the development of potential biocatalysts. SfaB is an acyladenylate‐forming enzyme that adenylates a unique building block, 3‐isocyanobutanoic acid, in the biosynthetic pathway of the diisonitrile

sulfide has been shown to generate short peptides via the formation of cyclic aminoacid N-carboxyanhydrides (NCAs). Here, we show that the polymerization of valine-NCA in the presence of fatty acids yields acylated aminoacids and peptides via a mixed anhydride intermediate. Notably, Nα-oleoylarginine, a product of the reaction between arginine and oleic acid in the presence of valine-NCA, partitions

The present invention relates to methods for synthesizing compounds of formula I or pharmaceutically acceptable salts thereof: (I) wherein each of X, Alk, and W are as defined and described herein.
The present invention provides a cosmetic composition containing (A) a powder composed of one or more kinds of the N-medium-chain-acyl basic amino acid powder represented by the following formula (I), (B) an inorganic powder, and (C) an oil material:
wherein R is a saturated or unsaturated straight hydrocarbon group having 5-9 carbon atoms, and m is an integer of 1-4.
The present invention aims to provide a medium-chain acyl basic amino acid derivative which, when blended in a liquid 5 cosmetic such as skin lotion, skin milk and the like, suppresses gelation while maintaining affinity to the skin and the like and can afford a stable preparation.
The present invention relates to a compound represented by the formula (1)
wherein each symbol is as described in the DESCRIPTION, or a salt thereof.
