The present invention relates to a PYY or PP peptide derivative or analogue thereof derivatised with one or more serum albumin binding side chains comprising a dis-tal tetrazole or carboxylic acid group. Moreover, the invention relates to compositions hereof and methods of treatment of conditions responsive to Y receptor modulation.
Chiral amplification is an interesting phenomenon in supramolecular chemistry mainly observed in complicated systems in which cooperative effect dominate. Herein, chiral, supramolecular, propeller‐like architectures have been constructed through coassembly of an achiral disk‐shaped molecule and chiral amino acid derivatives driven by intermolecular hydrogen bonding. Both the “sergeants‐and‐soldiers”

The invention provides compounds based on ceramide analogues of the general the general formula (I), wherein R1= H or CH2OH; R2 = C8 to C16 alkyl; R3 = C7 to C15 alkyl, cis-heptadec-8-en-1-yl, CH(R1)NHCOR4, CH=CHCOOR4 or CH(OH)CH(OH)COOR4; R4 = C7 to C16 alkyl. The compounds of the general formula (I) are used as transdermal penetration enhancers. Pharmaceutical and cosmetic compositions, containing ceramide analogues of the general formula (I) in the amount from 0.1 to 5.0 w/w percent, preferably in the amount from 0.1 to 1.0 w/w percent.
The invention relates to a novel class of gelling agents, to a process of preparing said agents, to the use of said agents to prepare gels, and to the gels thus obtained. A gelling agent or thickener according to the invention comprises a core which is functionalized with three amino acid derived groups by means of an amide or urea linkage. It may be used to gelate or thicken numerous solvents.
