The next stop for PEGylated protein drugs: Biosimilar

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 Development Multiple major pharma companies have been busy […]

FDA Guidelines on PEGylated Protein Drug Immunogenicity

Immune responses to therapeutic protein products may pose problems for both patient safety and product efficacy. Immunologically based adverse events, such as anaphylaxis, cytokine release syndrome, and cross-reactive neutralization of endogenous proteins mediating critical functions, have caused sponsors to terminate the development of what otherwise may have been efficacious therapeutic protein products. Potential Effects of […]

Thiolated PEGs Can Stabilize or Destabilize Gold Nanoparticles

PEG reagents are commonly used to prepare stable colloidal metal nanoparticle dispersion such as gold and silver through PEG thiol chemistry among other pegylation strategies. It typically works by replacing citrate or other capping ligands. How PEGs Control Variability in Gold Nanoparticles Did you know? By controlling the ratio of PEG-SH reagents to AuNP, you […]

Hyaluronic Acid: Beauty’s Secret Weapon

A new ingredient is sweeping the anti-aging beauty scene and completely revolutionizing it. Where injections once ruled the beauty industry, Hyaluronic Acid is now stepping in. How Hyaluronic Acid Works This natural ingredient helps reverse the signs of anti-aging by greatly diminishing fine lines and wrinkles. Hyaluronic acid works in the skin to absorb water, […]

The First Human Head Transplant Scheduled for 2017

How the Human Head Transplant Will Happen A human head transplant sounds like something out of a science fiction movie but soon it will become reality. Valery Spiridonov, a Russian computer scientist with Werdnig-Hoffman disease, will be undergoing surgery at the end of 2017. Surgery is expected to take 36 hours and will be done […]

3D PEG Hydrogels Supported Stem Cells for Soft Tissue Regeneration

Soft tissue defects are relatively common, yet currently used reconstructive treatments have varying success rates. The common treatments also have serious potential complications such as unpredictable volume loss and reabsorption. How PEGs Support Stem Cell Regeneration Human adipose-derived stem cells have great potential for use in soft tissue regeneration, especially when combined with a supportive […]

What’s the Difference: Biopolymers vs. Synthetic Polymers

What is the Difference? Bipolymers A major defining difference between biopolymers and other polymers can be found in their structures. All polymers are made of repetitive units called monomers. Biopolymers often have a well-defined structure, though this is not a defining characteristic. The exact chemical composition and the sequence in which these units are arranged […]

4 Pegylated Drugs Approved by FDA in Recent Years

FDA-Approved PEGylated Drugs & Their Uses 1. Plegridy (Biogen 2014) PEGylated Interferon Beta-1a for the treatment of patients with relapsing forms of multiple sclerosis. 2. Naloxegol (Movantik) (AstraZeneca 2014) PEGylated naloxol for the treatment of opioid-induced constipation in adults patients with chronic non-cancer pain. 3. Pegnesatide (Omontys) (Takeda Pharmaceuticals, 2012) To treat anemia associated with […]

PEG Reagents for Surface Functionalization of Carbon Nanotubes and Graphenes

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 Works Pyrene is conjugated to PEG through a very stable amide bond. It is a […]
