Medchemexpress LLC HY-N1441 1mg Medchemexpress, Afzelin CAS:482-39-3 Purity:>98%
Medchemexpress, HY-N1441 1mg Afzelin CAS:482-39-3 Afzelin (Kaempferol-3-O-rhamnoside) is is a flavonol glycoside found in Houttuynia cordata Thunberg and is widely used in the preparation of antibacterial and antipyretic agents, detoxicants and for the treatment of inflammation. Afzelin attenuates the mitochondrial damage, enhances mitochondrial biogenesis and decreases the level of mitophagy-related proteins, parkin and PTEN-induced putative kinase 1. Afzelin improves the survival rate and reduces the serum levels of alanine aminotransferase and pro-inflammatory cytokines in D-galactosamine (GalN)/LPS -treated mice. Purity:>98% Medchemexpress has over 10000 novel life-science reagents, reference compounds, APIs and natural compounds for laboratory and scientific use. Other quantity can also be offered.
