Effects of annulatophenone, annulatophenonoside, and acetylannulatophenonoside on brain synaptosomes and small cerebral vessels [PDF]

Pharmacia
Three benzophenones (annulatophenone Hd15, annulatophenonoside Hd21, and acetylannulatophenonoside Hd22) isolated from the aerial parts of Hypericum annulatum Moris were evaluated for their neuroprotective properties.

Prenylated Benzophenones from

Natural Product Communications, 2008
The roots of Hypericum hypericoides (Clusiaceae) have yielded five prenylated benzophenone derivatives. Three of these are new: 18-hydroxy-7-epi-clusianone, 18-hydroxyclusianone, isolated as the acetate, and 18-hydroxyhyperibone K.

Blood pressure changes during pregnancy in relation to urinary paraben, triclosan and benzophenone concentrations: A repeated measures study

Environment International, 2019
Previous studies have proven the endocrine-disrupting properties and health hazards of parabens, triclosan, and benzophenones, but their relationship with blood pressure during pregnancy remains unknown.

Determination of the pKa of Benzophenones in Ethanol-Water

Molecules, 2000
The pKa of monohydroxylated benzophenones was determined by UV spectroscopy. The values obtained are coherent with the resonant forms and hydrogen bond intramolecular of the analyzed compounds.

Synthesis of Benzophenone Glucopyranosides fromPhaleria macrocarpaand Related Benzophenone Glucopyranosides

Bioscience, Biotechnology, and Biochemistry, 2009
The first total syntheses of benzophenone glucopyranosides reported from Phaleria macrocarpa and related benzophenone glucopyranosides were successfully carried out. The alkoxy groups present ortho to the carbonyl group in polyalkoxybenzophenones were selectively deprotected by AlCl(3)-PhNMe(2) in high yields, leaving other alkoxy groups unaffected. It

Chemoselective C-benzoylation of phenols by using AlCl3 under solvent-free conditions

Bulletin of the Chemical Society of Ethiopia, 2015
Substituted phenols were chemo-selectively reacted with benzoylchloride in presence of aluminum chloride under solvent-free condition to afford the corresponding 2'-hydroxy aryl benzophenones in excellent yields (72-96%).
