Precise and safe delivery of drugs to target sites has always been an important task for researchers in modern medicine. With the development of nanotechnology, a variety of nanodrug delivery systems (NDDS) have been designed and prepared, such as the most familiar liposomes, polymer nanoparticles, and metal nanoparticles. However, a new kind of drug delivery system has also gradually emerged in ...
Antibody-drug conjugates (ADCs) combine potent small-molecule drugs with monoclonal antibodies for targeted cancer therapy. A major challenge is loading enough drug onto each antibody without compromising solubility or circulation time. Introducing polyethylene glycol (PEG) linkers between the antibody and drug payload can address this. PEG is hydrophilic, biologically inert, and FDA‐recognized ...
Introduction PEGylation, the process of attaching polyethylene glycol (PEG) chains to therapeutic molecules, has become a cornerstone in pharmaceutical development. This technique improves the pharmacokinetic and pharmacodynamic properties of drugs, enhancing their stability, solubility, and circulation time while reducing immunogenicity. Since its first FDA-approved application in 1990 with ...
As spring arrives, so does a renewed focus on cleaning, quality, and process validation in pharmaceutical facilities. Whether it’s a routine seasonal turnover or preparation for ramped-up production cycles, spring is a critical time in the pharmaceutical industry for equipment maintenance, cleaning validation, and ensuring product purity. Behind every cleanroom, batch reactor, or ...

Introduction Cytochrome P450 (CYP) refers to a family of enzymes that play a fundamental role in the metabolism of various substances within the body, particularly drugs, toxins, and endogenous compounds. These enzymes are crucial for the detoxification processes in the liver and affect the pharmacokinetics of numerous medications. Understanding the function and importance of cytochrome P450 is ...
What Is PROTAC Technology? Proteolytic targeting chimera (PROTAC) is a new type of drug design technology that works by inducing the degradation of target proteins. Unlike conventional small molecules that typically inhibit protein function, PROTACs facilitate the ubiquitination and subsequent degradation of specific proteins. This bifunctional molecule consists of two distinct elements: a ...
Introduction Microarray printing technology has revolutionized the field of genomics and proteomics, and its application in glycobiology is no exception. Glycobiology, the study of carbohydrates and their biological functions, relies heavily on the ability to analyze large-scale carbohydrate interactions. Microarray printing in glycobiology enables the precise and high-throughput analysis of ...
Recombinant protein drugs are protein-based therapeutic drugs which are produced by using DNA recombination technology or other biotechnological methods. These drugs include cytokines, peptide hormones, recombinant enzymes, monoclonal antibodies, and fusion proteins. Compared to traditional low-molecular-weight synthetic drugs, recombinant protein drugs have advantages such as high specificity, ...
Protein phosphorylation is an important post-translational modification process that involves adding a phosphate group to an amino acid residue in a protein, usually a serine, threonine, or tyrosine residue. Protein phosphorylation plays a key role in regulating various biological processes within the cell, including signal transduction, cell cycle, and metabolism. Therefore, detecting protein ...
Therapeutic monoclonal antibodies (mAbs) are a class of antibody drugs that are highly uniform and have pharmacological effects against a single epitope obtained through molecular biology. In the process of new drug development, the study of pharmacokinetics is of great significance. The result can be used to guide the screening and development of drugs, and support the evaluation of their ...
Glycosylation impurities are a type of chemical commonly encountered in biochemical, medical, and pharmaceutical chemistry research. The presence of these impurities can affect the efficacy, safety, and stability of drugs. Therefore, the detection and analysis of glycosylation impurities are crucial in ensuring the quality and therapeutic effectiveness of pharmaceutical products.What are ...
Antibody-drug conjugates (ADCs) represent a groundbreaking class of therapeutics that combine the specificity of monoclonal antibodies (mAbs) with the potent cytotoxic effects of small-molecule drugs. This synergistic approach allows for targeted delivery of the cytotoxic agent to cancer cells while sparing healthy tissues, thereby reducing side effects and enhancing therapeutic efficacy. ADC ...

Peptide drugs are bioactive molecules composed of multiple amino acids connected by peptide bonds. Typically, they are made up of 10~100 amino acids, with a relative molecular mass less than 10,000. Most peptide drugs are derived from endogenous peptides or natural peptides, so they have little or no side effects on the human body. Compared with protein drugs, peptide drugs also have advantages ...
