N-aminoimidazolidin-2-one peptidomimetics
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
This report describes the synthesis of N-aminoimidazolidin-2-one (Aid) peptidomimetics by alkylation of the urea nitrogen of a semicarbazone residue using ethylene bromide. The abstract states the Aid scaffold combines electronic and structural constraints to rigidify the peptide backbone as an aza variant of a Freidinger-Veber lactam. The authors report the synthesis and isolation of 25 Aid peptides, including eight GHRP-6 analogues, to demonstrate the method's utility for controlling conformation.
Abstract
The synthesis of N-aminoimidazolidin-2-one (Aid) peptidomimetics has been achieved by alkylation of the urea nitrogen of a semicarbazone residue using ethylene bromide. The Aid scaffold combines electronic and structural constraints to rigidify the peptide backbone in the equivalent of an aza variant of a Freidinger-Veber lactam. The syntheses and isolation of 25 Aid peptides, including eight GHRP-6 analogues, are reported to demonstrate the utility of this method for controlling conformation.
pepmg summarizes the peer-reviewed literature and links to every source. It sells nothing and ships nothing. Where an FDA label, a peer-reviewed study or a clinical-trial registry entry (labeled trial registry, not peer-reviewed) has published a dose, pepmg reports it with the source named; it gives no personalized recommendations and no administration technique. Don't just trust this summary: follow the citation to its source and read it yourself. Research use only.
