New Iris Kits for the Synthesis of Peptoids and N-Alkylated Peptides

Peptides as pharmaceutical compounds suffer from unfavorable pharmacokinetics which is, among other things, due to a slow uptake into cells and rapid proteolytic cleavage. N-Alkylation of peptides is a valuable tool to overcome these limitations. We now offer new kits that enable the facile preparation of peptoids and N-alkylated peptides.
