2,4-Dibromo-1,3-dihydroxy-9H-xanthen-9-one
The title compound, C13H6Br2O4, derived from xanthone, a fundamental structural framework of active ingredients in many medicinal plants, and was synthesized by bromination of 1,3-di-hydroxyxanthen-9-one with N-bromo-succinimide. The mol-ecular conformation is essentially planar, the dihedral angle between the benzene rings being 1.1 (4)°. This conformation is favorable for the formation of an ...
متن کامل(E)-2-Methoxy-9-(2-methoxy-9H-xanthen-9-ylidene)-9H-xanthene
The title compound, C28H20O4, was synthesized by a bimolecular Zn-HCl reduction in glacial acetic acid using the meth-oxy-substituted xanthone as a starting material. The crystal structure shows that the 2,2'-meth-oxy-bixanthenyl-idene unit is an E-type conformation anti-folded conformer. The mol-ecule lies on an inversion center. The meth-oxy group is almost coplanar with the attached benzene ...
متن کاملAcetonitriletriaqua[3-ethoxy-1,8-(3,6,9-trioxaundecane-1,11-diyldioxy)-9H-xanthen-9-one]terbium(III) tris(perchlorate)
In the title compound, [Tb(CH(3)CN)(C(23)H(26)O(8))(H(2)O)(3)](ClO(4))(3), the Tb(3+) atom is eight-coordinated by one N atom of an acetonitrile molecule, three water O atoms and four ligand O atoms. The Tb(3+) atom is located on one side of the macrocycle and the carbonyl oxygen coordinated to the terbium [Tb1-O1= 2.210 (3) Å] is bent out of the xanthone plane by 0.514 (3) Å. The geometry arou...
متن کاملSynthesis and evaluation of antiproliferative activity of substituted N-(9-oxo-9H-xanthen-4-yl)benzenesulfonamides.
Several novel N-(9-oxo-9H-xanthen-4-yl)benzenesulfonamides derivatives were prepared as potential antiproliferative agents. The in vitro antiproliferative activity of the synthesized compounds was investigated against a panel of tumor cell lines including breast cancer cell lines (MDA-MB-231, T-47D) and neuroblastoma cell line (SK-N-MC) using MTT colorimetric assay. Etoposide, a well-known anti...
متن کامل1,3,6-Trihydroxy-7-methoxy-2,8-bis(3-methylbut-2-enyl)-9H-xanthen-9-one
The title compound (trivial name α-mangostin), C(24)H(26)O(6), isolated from Cratoxylum glaucum, is characterized by a xanthone skeleton of three fused six-membered rings and two 3-methyl-but-2-enyl side chains. The three rings in the structure are nearly coplanar, with an r.m.s. deviation for the tricyclic ring system of 0.0014 Å. The two 3-methyl-but-2-enyl side chains are in (+)-synclinal an...
