Staphylokinase (Sak) holds promise for use in thrombolytic therapy for acute myocardial infarction. However, its immunogenicity is a major disadvantage under clinical conditions. PEGylation has become a sophisticated method to decrease that immunogenicity. In this report, according predicted epitope from the active center, five residues, including Gly79, Leu82, Lys84, Ala97, and Arg104 have bee...

The mPEG-aldehyde PEGylation with two different PEG sizes and two proteins was experimentally determined with respect to yield, conversion, and selectivity. The kinetic behavior of these PEGylation reactions was simulated using a numerically solved set of differential equations. We show that the assumption of an inactivation of mPEG-aldehyde is crucial for the simulation of the overall PEGylati...

The efficacy of protein-based medicines can be compromised by their rapid clearance from the blood circulatory system. Achieving optimal pharmacokinetics is a key requirement for the successful development of safe protein-based medicines. Protein PEGylation is a clinically proven strategy to increase the circulation half-life of protein-based medicines. One limitation of PEGylation is that ther...

PEGylation is a widely adopted process to covalently attach a polyethylene glycol (PEG) polymer to a protein drug for the purpose of optimizing drug clinical performance. While the outcomes of PEGylation in imparting pharmacological advantages have been examined through experimental studies, the underlying molecular mechanisms remain poorly understood. Using interferon (IFN) as a representative...

The aim of this study was to develop PEGylation liposomes formulations of erlotinib and evaluate their characteristics, stability, and release characteristics. The average particle sizes and entrapment efficiency of PEGylation erlotinib liposomes are 102.4±3.1 nm and 85.3%±1.8%, respectively. Transmission electron microscopy images showed that the liposomes dispersed well with a uniform shape a...

PEGylation changes the physical and chemical properties of the biomedical molecule, such as its conformation, electrostatic binding, and hydrophobicity, and results in an improvement in the pharmacokinetic behavior of the drug, while it also causes some disadvantages of which cannot be neglected. The available data manifests that polyethylene glycol (PEG) itself shows potential risk, such as im...

Background: Human growth hormone (hGH) use is increasing due to its important biological functions and therapeutic applications, the use of growth hormone for the treatment of obesity, short stature, burns and the importance of this hormone for athletes. Nowadays, the short half-life of hGH is a major challenge associated with the usage of this drug in the world. PEGylation is an effective appr...

RATIONALE Infusions of apolipoprotein AI (apoAI), mimetic peptides, or high-density lipoprotein (HDL) remain a promising approach for the treatment of atherosclerotic coronary disease. However, rapid clearance leads to a requirement for repeated administration of large amounts of material and limits effective plasma concentrations. OBJECTIVE Because pegylation of purified proteins is commonly...
