AbstractMaleimides are essential compounds for drug conjugation reactions via thiols to antibodies, peptides and other targeting units. However, one main drawback is the occurrence of thiol exchange reactions with, for example, glutathione resulting in loss of the targeting ability. A new strategy to overcome such retro-Michael exchange processes of maleimide–thiol conjugates by stabilization of the […]
This article reviews PEG linkers, their structure, applications, and the many advantages they bring to the world of medicine and science.
PEGylation is a chemical modification process that involves attaching polyethylene glycol (PEG) molecules to proteins. Learn about what PEGylated proteins are and their applications in today’s world.

Learn more about how PEGs can be used to optimize gene editing and systemic gene delivery.
A deep dive into anti-PEG antibodies, how they could affect the performance of medicines, and how Creative PEGWorks can help your pharmaceutical projects.
Pegfilgrastim is a PEGylated form of the recombinant human granulocyte colony-stimulating factor analog filgrastim. It serves to stimulate the level of white blood cells. Pegfilgrastim has a human half-life of 15 to 80 hours, much longer than the parent filgrastim (3–4 hours).Pharma Companies & PEGylated Drug DevelopmentMultiple major pharma companies have been busy developing biosimilar […]
PEGylated pyrene derivatives can be used for the surface functionalization of carbon nanotubes and graphenes via the strong (close to irreversible) pi-pi stacking between the pyrene and the aromatic rings on single wall and multi-walled carbon nanotubes. How Surface Functionalization WorksPyrene is conjugated to PEG through a very stable amide bond. It is a very […]
To date, only eleven PEGylated proteins, antibody fragments, oligonucleotides, and small molecules that have been approved by the FDA are on the market. Available PEGylated DrugsThis includes PEGylated bovine adenosine deaminase: pegademase bovine (Adagen); and PEGylated l-asparaginase: pegaspargase (Oncaspar); PEGylated products of interferon-alpha (IFN-alpha): peginterferon-2b (PegIntron) and peginterferon-2a (Pegasys); PEGylated granulocyte colony stimulating factor (GCSF): […]
