Nishino, Chikao published the artcileAntibacterial activity of flavonoids against Staphylococcus epidermidis, a skin bacterium, Related Products of tetrahydropyran, the publication is Agricultural and Biological Chemistry (1987), 51(1), 139-43, database is CAplus.
An investigation was carried out on Okinawan plants to find antibacterial compounds against a human skin bacterium, S. epidermidis, which causes acne vulgaris. A medicinal plant, Elaeagnus glabra, showed significant activity, and (-)-epigallocatechin (I) was isolated from the plant as an antibacterial constituent against the bacterium. Twenty-six flavonoids related to I were tested for antibacterial activity, galangin (II) being the most active species. Although a structure-activity study was attempted, no clear structural factor was deduced.
Agricultural and Biological Chemistry published new progress about 69097-99-0. 69097-99-0 belongs to tetrahydropyran, auxiliary class Other Aliphatic Heterocyclic,Benzene,Phenol,Ether,Inhibitor, name is 5,7-Dihydroxy-2-(3-hydroxy-4-methoxyphenyl)chroman-4-one, and the molecular formula is C16H14O6, Related Products of tetrahydropyran.
