Cat. No.: HY-112624J
CAS No.: 9004-54-0
Synonyms: Dextran 4; Dextran D4; Dextran T4(MW 3200-4800)
Dextran 4,000 is a mucus rheology modifier. The dextran molecules in Dextran 4,000 can reduce the cross-link density of mucus through osmotic effects and hydrogen bond substitution, and reduce viscoelasticity and improve the mucociliary/cough clearance index by destroying the DNA-mucin network structure in mucus. Dextran 4,000 has the ability to improve the rheological properties and clearance ability of cystic fibrosis (CF) sputum, and can be used in the study of inhalation therapy or aerosol delivery of mucostatic respiratory diseases. The Dextran series of compounds are also natural polysaccharide drug carriers that can be connected to drugs through covalent bonding methods such as ester bonds, amide bonds or click chemistry, or self-assembled to form carriers such as nanoparticles and hydrogels. Dextran is biodegradable and biocompatible, and can achieve targeted delivery and controlled release of drugs. Dextran derivatives can prolong the half-life of drugs, increase local concentrations, and reduce the activity of immune clearance .

Cat. No.: HY-N7435R
CAS No.: 54814-64-1
Synonyms: (±)-Massoia lactone (Standard)
Massoia lactone (Standard) ((±)-Massoia lactone (Standard)) is the analytical standard of Massoia lactone (HY-N7435). This product is intended for research and analytical applications. Massoia lactone ((±)-Massoia lactone) is a natural lactone-based biosurfactant with antifungal (fungal), antibiofilm, and cytotoxic activities. Massoia lactone inhibits fungal hyphal growth and spore germination, and induces fungal cell necrosis by forming membrane pores, reducing ergosterol, elevating ROS, and causing leakage of intracellular components. Massoia lactone inhibits the viability and proliferation of tumor cells. Massoia lactone degrades the extracellular polymeric substances of polymicrobial biofilms, penetrates the biofilm matrix, inhibits the growth of planktonic oral bacteria (bacterial), and reduces surface tension through its amphiphilic properties. Massoia lactone is a low-toxicity, biodegradable food additive with a coconut cream aroma, which can be used for flavor improvement and also serves as a quality control marker for Cs-4 mycelium. Massoia lactone can be used for research on Fusarium head blight, malignant tumors, and oral polymicrobial biofilm-associated dental diseases .

Ionizable lipids are a class of specialized, functional lipid molecules with pH-sensitive charge characteristics. They are primarily divided into two major categories: ionizable cationic lipids and ionizable anionic lipids, though the term typically specifies ionizable cationic lipids within the biomedical field. Structurally, these lipids consist of an ionizable hydrophilic headgroup, a biodegradable linker, and hydrophobic tails. Their primary application is serving as the key delivery vehicle in lipid nanoparticles (LNPs) to encapsulate negatively charged nucleic acid macromolecules, such as mRNA vaccines, siRNA therapeutics, and CRISPR gene-editing components. In a physiological, neutral environment, they remain electrically neutral to minimize systemic toxicity and prolong circulation time. Upon entering the acidic microenvironment of cellular endosomes, however, they undergo protonation to become positively charged, thereby inducing membrane fusion and enabling the highly efficient intracellular release of the nucleic acid cargo. Consequently, they serve as the technological cornerstone for bringing nucleic acid therapies into clinical application.

To accelerate the translational process of cutting-edge nucleic acid drugs, MCE has meticulously constructed an ionizable lipid compound library containing 93 high-performance molecules, aiming to provide researchers and pharmaceutical professionals with a high-throughput, multi-dimensional lipid screening platform.
