Poly-(α-L-glutamic acid) is a synthetic polypeptide of L-Glu linked by the alpha-amino groups (α-PGA). These polyanionic and biodegradable polymers can be used for a variety of purposes.
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...
Mutant or modified aminoacyl tRNA synthetases (aaRS) have been used to charge non-natural amino acids to the corresponding tRNA, which incorporates them into polypeptides or proteins during recombinant synthesis.
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.
Potential alternatives to PEGs, polypeptoids in general and polysarcosine (PSR) in particular stand out in terms of safety, synthetic control and versatility.
PEGs show a spectrum of unique physical and chemical properties, which have been described in literature extensively by the pioneers in PEGylation: Harris, Veronese and recently by Hermanson. Here are summarized the most common known properties.
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.
The reaction between a tetrazine (Tz) and a trans -cyclooctene (TCO) is the innovative third generation Click reaction that proceeds without the use of copper or other catalyst. It is rapid, fully bioorthogonal and excels at very low concentrations.
Click chemistry is a convenient method to chemoselectively functionalize peptides at specific positions. We offer a variety of different propargyl amino acids for both Fmoc and Boc strategies, for enzymatic synthesis, as well as preloaded resins for SPPS.
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.
