Cayman Gemifloxacin (Mesylate); Purity- Greater Than Or Equal To

Hordenine (Item No. 21626) is a naturally occurring alkaloid found in a variety of plants, most commonly germinated barley (Hordeum species) from which the name is derived, and is structurally classified as a phenethylamine.^, It is biosynthesized by the step-wise double methylation of tyramine (Item No. ). Hordenine binds to and activates the dopamine D₂ receptor (K_i = 13 µM) but antagonizes D₂ receptor β-arrestin recruitment. It inhibits tyrosinase activity and expression at concentrations ≥ 50 µM resulting in reduced melanin accumulation in human melanocytes. Hordenine is present in significant amounts in beer and can be measured in serum in the free form, for up to 2 hours, and the glucuronidated form, for up to 6 hours, after beer consumption. This product is intended for research and forensic applications.
