A conjugation of bile acids with peptidesviaCu(I)-catalyzed click chemistry has been described. Novel bile acidâpeptide conjugates linked via a 1,2,3-triazole moiety based on cholic, deoxycholic and lithocholic acid derivatives were synthesized using Cu(I)-catalyzed 1,3-dipolar cycloaddition (âclickâ reaction). It was shown that up to three peptide fragments can be attached to a central steroid core, thus forming complex three-dimensional polyconjugate structures, which can find important applications in biochemistry, medicinal chemistry, and coordination chemistry.

Ugi-click-strategy was employed for the synthesis of 12–28 membered 1,2,3-triazole derived macrocyclic peptidomimetics. The Ugi reaction with acid components bearing acetylenic fragments and azidoisocyanides provided the corresponding peptidomimetics in up to 97% isolated yield. The subsequent CuAAC click reaction with these bifunctional substrates containing both acetylene and azide groups was investigated

1,2,3-Triazole conjugates of betulonic acid with peptides were synthesized by 1,3-dipolar cycloaddition of azido peptides to N-(3-oxolup-20(29)-en-28-oyl)-4-ethynylaniline.

Cycloaddition of betulonic acid propargyl ester and azido-containing Boc-protected peptides afforded the corresponding 1,2,3-triazole-linked conjugates, whose anti-inflammatory properties were studied.

A combination of the Passerini reaction and copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC, click reaction) was used to synthesize triazole-containing macrocyclic depsipeptides. The key factors determining the direction of macrocyclization are the chain length of the initial depsipeptide and the presence of rigid fragments therein. The proposed strategy makes it possible to obtain monomeric (12-13-membered) and dimeric (24-28-membered) triazole-containing cyclic depsipeptides in up to 97% yield.
