Overview
NOF has been producing a high-quality activated PEGs, SUNBRIGHT series, which possess the most suitable quality for preparation of physiologically active drug and biologics. SUNBRIGHT series are characterized as extremely high-purity PEGs with a variety of functional groups, whereby the products of this series are recognized as optimal PEGylation drugs. As illustrated in this figure, application of the activated PEGs with various functional groups enable introduction of the PEG chains into drugs, enzymes, phospholipids and other biologics. Covalent conjugation of hydrophobic macromolecules with activated PEGs leads to the formation of macromolecular micelles (Polymer Micelles), which allow homogeneous dispersion of hydrophobic drugs in aqueous media. Furthermore, when the PEGylated phospholipids are used as liposomes, the aqueous layer can be added to its surface, with homogeneous dispersal of the liposome preparations encapsulating drugs within them.

As stated above, PEGylation plays an important role in the stabilization of drugs, reduction of their antigenicity and decrease in the drug doses, besides augmenting the targeting ability via binding biologics onto their surfaces. We can do supply our activated PEGs from small scale reagent grade to huge amount GMP grade with high purity.

 

PEGylation
PEGylation technology is applied for biologics modifications such as cytokines, antibody fragment, interleukins, hormones, oligonucleotides and some of proteins and peptides.

PEGylation can be effected to

Improving Bioavailability
Prolonging Blood Circulation
Maximizing Pharmacokinetics
Low-profiling Immunogenicity
NOF provides high-performance activated PEGs for PEGylated drugs from early development stage to commercial use with our 20 years of experience of manufacturing high-quality methoxy polyethylene glycol, which is a starting material of activated PEG for pharmaceutical area. Our activated PEGs have a narrow polydisperity and low diol content with wide range of molecular weight, from 2kDa to 80kDa.

Analytical Technology

NOF has more than 20 years history for manufacturing of high-quality mPEGs and Activated PEGs. These experiences enable NOF to have thorough knowledge of PEGs and considerable achievement in analysis of Activated PEGs. We also have invented innovative analytical methods for assaying purity of activated PEGs and for determining impurity levels. (*Patent No.: JP4543917) Previously, the activity for activated PEGs is measured by NMR. However, this method is not very good detection due to polymer, especially for high molecular weight. We developed the analysis method by using HPLC. As the result of the analysis, the activity sometime seems lower than the result of NMR because main peak can completely separate from non-active peak and activated impurity peaks (like dimer).
