acceptable results. According to this approach an efficient formation of Schiff bases was achieved in the presence of TiCl(4). Substances were isolated by reversed phase chromatography; in some cases isomers were additionally separated by chiral chromatography on Chirobiotic T. When tested on human recombinant melanocortin receptors all the tertiaryamides showed some binding affinities; for the highest affinity
Disclosed are derivatives of amphotericin B (AmB) characterized by improved therapeutic index compared to AmB. The AmB derivatives include C16 ureas, carbamates, and amides according to Formula (I); C3′-substituted C16 ureas, carbamates, and amides according to Formula (II); C16 acyls according to Formula (III); C2′epi-C16 ureas, carbamates, and amides according to Formula (IV); and C16 oxazolidinone derivatives according to Formula (V). Also disclosed are pharmaceutical compositions comprising the AmB derivatives, and therapeutic methods of using the AmB derivatives.
Sustainable and efficient manufacturing methods for N-methylated peptides remain underexplored despite growing interest in therapeutic N-methylated peptides within the pharmaceutical industry. A methodology for the coupling of C-terminally unprotected N-methylamino acids mediated by an isostearic acid halide (ISTAX) and silylating reagent has been developed. This approach allows for the coupling of
The invention relates to methods for the preparation of peptides which are a C-terminal amide derivatives by a combination of solid-phase synthesis and post assembly solution phase synthesis. The peptides which are a C-terminal amide derivatives are further converted to peptide acetates. The invention also relates to pure peptide acetates and to protected peptide precursors.
