a) Catalyst-free Click Reaction Cycloaddition reactions such as the [3+2] azide-alkyne and the [4+2] Diels-Alder reaction, are becoming common conjugation techniques. Applications range from imaging, drug design and development of sensors, thereby spanning the fields of chemical biology, material science, surface and polymer chemistry as well as many other fields. Introduced in 2002, the copper-catalyzed variant of the azide-alkyne cycloaddition (CuAAC) reaction has found broad applicability in t...

Protein and lipid glycosilation is a life-governing and omnipresent process. Glycoconjugates display a multitude of biological effects from protein folding and stabilization, energy storage, cell surface interaction through molecular recognition motifs for cell-cell communication, and structural support and protection.

Polyglutamates are well known to be highly biocompatible, biodegradable and multifunctional polymers, which have already been used as building blocks in polymer drug conjugates and polymeric micelles.

In this news section, we highlight three useful coupling reagents for peptide chemistry: PyCLOCK, PyAOP and HDMA.

Conjugates of PEG and folic acid or cholesterol, respectively, combine the positive properties of these molecules. Those conjugates are available with a wide variety of functional groups and different PEG chain lengths to suit your needs.

Fmoc-L-Dap(2-Boc-aminoethyl)-OH is the first in a series of new triamino acid building blocks. This azalysine is useful for introducing positive charges into a peptide, or for creating branched structures.

Surprising behavior of NXO-peptides. It is a significant property of peptides that oxalo-retro azapeptides have the same donor and acceptor distances and properties for hydrogen bridge formation as a tripeptide fragment and therefore induce beta-sheet formation at this position.

Alkylating the Nitrogen of an amide bond results in peptoid structures, leading to conformational restrains, like N-methylation and allows backbone derivatisation. Applications already have been published with Cilengitide, Piscidin 1, and MC4 receptor agonist.

The presence of catalytic copper, limits the in vivo application of the Click this reaction for several reasons. We offer custom synthesis of Strained Cyclooctynes and Substituted 1,2,4,5- Tetrazines as building blocks for fast Click reactions in the absence of any catalyst.
