L-Lysine (Standard) is the analytical standard of L-Lysine. This product is intended for research and analytical applications. L-lysine is an essential amino acid for humans with orally activity. L-lysine can inhibit the occurrence of HSV infections and is used in herpes research. L-lysine increases calcium absorption, reduces diabetes-related diseases, improves gut health, and alleviates pancreatic inflammation. L-lysine can be used in research on metabolism, infection, and inflammation. IC₅₀ & Target:L-lysine (150 mg/kg) promotes, but not initiates, bladder cancer. The administration of L-lysine to rats submitted to colovesical cystoplasty accelerates the development of transitional metaplasia of the intestinal epithelium.
L-lysine (10 mg/kg) treatment attenuates pancreatic tissue injury induced by L-arginine by inhibiting the release of the inflammatory cytokine IL-6 and enhance antioxidant activity. In Vivo:L-lysine (10?mg/kg, p.o., pre-treated or post-treated, administration duration 15 days) treatment attenuates pancreatic tissue injury induced by L-arginine by inhibiting the release of the inflammatory cytokine IL-6 and enhance antioxidant activity in acute pancreatitis mice model.

Anthraquinone is used as a precursor for dye formation and agrochemicals, existing in different organisms, such as bacteria, fungi, plants, and some animals. Anthraquinone has biological activities: anticancer, antiinflammatory, diuretic, antiarthritic, antifungal, antibacterial, antimalarial and antioxidant. Anthraquinone also plays an important role in the primary metabolism of plants by acting on the electron transport chain through the inhibition of energy transfer in the photosynthetic process. Anthraquinone can intercalates into DNA and inhibits the topoisomerase II (topo II) enzyme, resulting in cell death via Apoptosis.
