An efficient method for the reductive amination of carbonyl derivatives with ω-amino fatty acids catalysed by an iron complex Fe(CO)4(IMes) [IMes=1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene] by means of hydrosilylation was developed. A variety of pyrrolidines, piperidines and azepanes were selectively synthesised in moderate-to-excellent yields (36 examples, 47–97 % isolated yield) with a good functional group tolerance.

Novel remedies in the battle against multidrug-resistant bacterial strains are urgently needed, and one obvious approach involves antimicrobial peptides and mimics hereof. The impact of α- and β-peptoid as well as β3-amino acid modifications on the activity profile against β-lactamase-producing Escherichia coli was assessed by testing an array comprising different types of cationic peptidomimetics obtained by a general monomer-based solid-phase synthesis protocol. Most of the peptidomimetics possessed high to moderate activity toward multidrug-resistant E. coli as opposed to the corresponding inactive peptides. Nevertheless, differences in hemolytic activities indicate that a careful choice of backbone design constitutes a significant parameter in the search for effective cationic antimicrobial peptidomimetics targeting specific bacteria.
WRINKLE-IMPROVING AGENT

The invention provides a novel wrinkle-improving agent that has an effect of improving wrinkles, that does not entail problems of safety or pain even when applied to the skin, and that contains a very safe substance as an active component. A discovery was made that N-benzoyl-β-alanine, other specific β-alanine derivatives, and salts thereof have a wrinkle-improving effect, whereby a wrinkle-improving agent containing as an active component one, two, or more types of compounds selected from the group composed of these specific β-alanine derivatives and the salts thereof was developed.
