Cat. No.: HY-N1326 Purity: 98.85%
Handling Instructions Technical Support

Santamarine (Santamarin; Balchanin) is a sesquiterpene lactone found in Artemisia scoparia. Santamarine shows anti-inflammatory, antioxidant, anticancer and anti-photoaging activities. Santamarine suppresses UVA-induced phosphorylation of JNK and p38 MAPK, nuclear translocation of phosphorylated c-Fos and c-Jun, and AP-1-mediated MMP-1 transcription and secretion. Santamarine suppresses NF-κB signaling, iNOS, COX-2, TNF-α, and IL-1β production. Santamarine inhibits thioredoxin reductase activity, induces ROS production, mitochondrial apoptosis, G2/M cell cycle arrest, and DNA damage, and reduces cancer cell growth. Santamarine can be used for the photoaging, inflammatory diseases and cancer.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
