Conformations of substituted benzophenones
Acta Crystallographica Section B Structural Science, 2008The inclination of the two aryl rings (ring twists) in a series of benzophenone molecules has been examined. For each structure the dihedral angle (between the planes of the two sets of six aromatic C atoms) relates to both the steric considerations of the single molecule and the packing forces related to the crystal structure.

Prevalent polymorphism in benzophenones
Acta Crystallographica Section C Structural Chemistry, 2018We report here the crystal structures of dimorphs of 4-hydroxybenzophenone, C13H10O2, and 4-(dimethylamino)benzophenone, C15H15NO, as well as trimorphs of 4,4′-dimethylbenzophenone, C15H14O. The polymorphs were isolated from slow-evaporation conditions or from cocrystallization attempts.

4,4'-Methylenediiminobis(benzophenone)
Acta Crystallographica Section C Crystal Structure Communications, 1994The title compound [N,N'-bis(benzoylphenyl)methanediamine, C 27 H 22 N 2 O 2 ] was prepared by condensation of 4-aminobenzophenone (ABP) and formaldehyde at room temperature. In the molecule, two ABP moieties are linked by a methylene group. The bond lengths and angles within the two ABP groups are very similar; however, the dihedral angles between the

Benzophenone glycosides from Gnidia involucrata
Phytochemistry, 2000Six compounds have been isolated from the methanol extract of the aerial parts of Gnidia involucrata (Thymelaeaceae). They were identified as 2,3,4',5,6-pentahydroxybenzophenone-4-C-glucoside and 2,4',6-trihydroxy-4-methoxybenzophenone-2-O-glucoside, together with mangiferin, kaempferol-3-O-glucoside, yuankanin and manniflavanone by chemical and ...

Contact urticaria photoinduced by benzophenones
Contact Dermatitis, 2003A 31-year-old man presented with a 7-year history of recurrent facial dermatitis. Until 2 years ago this had occurred in the winter only, but now was also to be seen in the summer, involving the whole face including the lips. He likened it to a pruriginous sunburn that appeared within 6– 12 h and disappeared in 48 h via desquamation.

Antianaphylactic benzophenones and related compounds
Journal of Medicinal Chemistry, 1987The synthesis and biological properties of 85 benzophenones and related compounds are described. The majority of the compounds inhibit the release of leukotrienes (LT) C4 and D4 in vitro from sensitized guinea pig chopped lung. In addition, some of the compounds inhibited the release of LTs from passively sensitized human chopped lung and protected ...

Probing Proteomes with Benzophenone Photoprobes
2011Benzophenone photoprobes represent powerful tools for chemical proteomics. Upon UV irradiation, a benzophenone photoprobe can selectively form a covalent bond with its target protein in complex protein mixtures. Thus, photoprobes can be used to profile a wide variety of proteins in complex proteomes.
