In one aspect, the disclosure provides cross-linked materials that include multivalent lectins with at least two binding sites for glucose, wherein the lectins include at least one covalently linked affinity ligand which is capable of competing with glucose for binding with at least one of said binding sites; and conjugates that include two or more separate affinity ligands bound to a conjugate framework, wherein the two or more affinity ligands compete with glucose for binding with the lectins at said binding sites and wherein conjugates are cross-linked within the material as a result of non-covalent interactions between lectins and affinity ligands on different conjugates. These materials are designed to release amounts of conjugate in response to desired concentrations of glucose. Depending on the end application, in various embodiments, the conjugates may also include a drug and/or a detectable label.

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
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.
The present invention provides a composition containing component (A): a compound represented by the formula (1)
wherein each symbol is as described in the DESCRIPTION, or a salt thereof, and component (B): an anionic water-soluble m polymer, which suppresses syneresis and aggregation over time, is superior in the maintenance of viscosity in a wide pH range even in the presence of electrolyte or alcohol, and suppresses stickiness and sliminess.
