Bright Yellow Solid

Antibacterial and antioxidant for preventing and treating cancer.

ChEBI: Ubiquinone-9 is a member of ubiquinones. It has a role as an antioxidant and a human metabolite.

Coenzyme Q9 (Ubiquinone-9; Ubi-9) is a 9 isoprenyl group member of a family of ubiquinones that share a quinine chemical group but differ in the number of isoprenyl chemical subunits in their tail. The CoQ compounds are lipid soluble components of cell membranes.

The coenzyme Q (CoQ) can perform multiple functions such as electron and proton transport. CoQ9 performs similar functions to CoQ10 as the native CoQ in Caenorhabditis elegans. CoQ9 as well as other CoQ molecules may have an impact on cell life-span and these molecules are seeing increase usage in such studies.

The yellow crystals are purified by recrystallisation from pet ether and by chromatography on SiO2 plates and eluted with Et2O/hexane. The purity can be checked by HPLC (silica column using 7% Et2O/hexane). It has max 270nm ( 14,850) in pet ether. [NMR and MS: Naruta J Org Chem 45 4097 1980, Le et al.
