Ampyrone

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[1][2][3].
