Lipoamide-PEGs Confer Extra Strong Binding

Nanotechnology and nanobiotechnology using gold or silver particles, quantum dots or even magnetic particles are broadly diverse, rapidly expanding areas of study in medical diagnostics and therapeutics, sensoric and chemistry.

Polymers Enlarge the Potential of Biopharmaceuticals

The Biopharmaceuticals market, estimated at US$ 200 billion globally in 2013 by reportbuyer.com (Biopharmaceuticals - A Global Market Overview, 2013, London), is further projected to reach US$ 500 billion by 2020, growing at 13.5 % CAGR between 2010 and 2020.

Pharmacological Effects of Polymer Therapeutics

Small drug molecules and also large biomolecules like proteins or antibodies suffer rapid clearance from human body.

Amino-PEG-Acids for Increased Solubilization.

For introducing amino-PEG-acids into a peptide chain, several affordable building blocks are available with all conventional protecting groups. They can be incorporated at any sequence position by standard coupling protocols.

New: dPEG-Phospholipids for superior liposomes

Novel liposomes built of dPEG-Phospholipids with defined PEG chain length provide prolonged blood-circulation time and improved cellular uptake as administration carriers for drugs, delivering active molecules to the desired target.

Dendron Building Blocks for Click Chemistry

Dendrimers offer a new possibility to derivatize small molecules, surfaces or biopharmaceuticals with a monodisperse macromolecule and alter in this way properties like solubility and hydrophilicity. Immunogenicity and pharmacokinetics of pharmaceuticals will be improved. The synthetic approach for designing these dendrons of different generations is based on 2,2-bis(hydroxymethyl) propionic acid, which is a non-toxic and biocompatible building block.

The size can be designed from 250 g/mole for 1st generation dendrons to over 4400 g/mole with 5th generation compounds. Dendrimers can be designed reaching even a molecular weight of some 10.000 Da. As focal point alkyne and azido functions are used with appropriate counter parts in any type of click chemistry reaction. Olefinic functions offer the possibility for addition reaction or conjugation by metathesis reactions or photo reactions with the aid of UV light. For the modification of Gold surfaces sulphur bearing dendrons can be used, they also conjugate with biologicals via disulfide bridge formation.
