Ampyrone (4-Aminophenazone; 4-Aminoantipyrine) is a reversible and low-damage optical clearing agent and non-selective COX inhibitor based on UV absorption properties. Ampyrone can improve the optical transmittance of mouse skin and other tissues. Ampyrone can induce tissue refractive index matching by enhancing UV absorption, reduce light scattering, and achieve tissue transparency in vivo. Ampyrone reduces the synthesis of prostaglandin PGE2, thereby exerting anti-inflammatory, analgesic and antipyretic effects. Ampyrone inhibits DNA damage, cell apoptosis and immune cell phagocytosis induced by Doxorubicin (HY-15142A) and Cisplatin (HY-17394), etc., and participates in the regulation of toxicity in tumor chemotherapy .

Synonyms: Titanium dioxide
Titanium(IV) oxide is a photosensitizer and photocatalyst. Titanium(IV) oxide can be used as a pharmaceutical excipient such as a flow aid, coating agent, sunscreen, colorant, etc. Pharmaceutical excipients or pharmaceutical excipients refer to other chemical substances used in the pharmaceutical process other than the drug ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations that can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism and elimination (ADME) process of co-administered drugs. Titanium(IV) oxide can use light energy to generate electron-hole pairs to degrade pollutants. Photons excite electrons in TiO2 to generate active oxygen species (such as ·OH and ·O2 -), thereby oxidizing and mineralizing pollutants such as organic compounds and heavy metals. TiO2 can be used in the research of environmental remediation fields such as water treatment, air purification and self-cleaning materials .

Epilactose is an orally active prebiotic disaccharide. Epilactose resists gastrointestinal digestion, stimulates the intestinal epithelium, and induces myosin regulatory light chain phosphorylation, activating the perijunctional actin-myosin ring and paracellular transport. Epilactose produces short-chain fatty acids and organic acids through cecal microbial fermentation, induces paracellular calcium and iron absorption, lowers cecal pH, and increases cecal calcium and magnesium solubility. Epilactose inhibits hepatic cholesterol synthesis. Epilactose can be used for research on osteopenia, colon cancer, Crohn's disease, post-gastrectomy osteopenia and anemia, and obesity .
