3-O-Methyl-1-isomangostin
IN THE TITLE XANTHONE DERIVATIVE [SYSTEMATIC NAME: 9-hy-droxy-5,10-dimeth-oxy-2,2-dimethyl-11-(3-methyl-but-2-en-1-yl)-2,3,4,12-tetra-hydro-1,7-dioxatetra-phen-12-one], C(25)H(28)O(6), the xanthone ring system is roughly planar, with an r.m.s. deviation of 0.1038 (1) Å. The chromane ring is in a half-chair conformation and the 3-methyl-but-2-enyl substituent is axially attached with an (+)-anti...
متن کامل(E)-1-Methyl-5-(3-methyl-4-chlorophenoxy)-3-trifluoromethyl-1H-pyrazole-4-carbaldehyde O-acetyloxime
In the title mol-ecule, C(15)H(13)ClF(3)N(3)O(3), the pyrazole and benzene rings form a dihedral angle of 77.6 (3)°. In the crystal, mol-ecules related by translation along the a axis are linked into chains via C-H⋯O hydrogen bonds. The crystal packing is stabilized further by weak π-π [centroid-centroid distance = 3.734 (6) Å] and dipole-dipole inter-actions [C⋯O = 3.174 (2) Å].
متن کاملDiethyl(μ3-2-methyl-4-oxo-4H-pyran-3-olato-κ4 O 3,O 4:O 3:O 3)tris(μ2-2-methyl-4-oxo-4H-pyran-3-olato-κ3 O 3,O 4:O 3)trizinc toluene disolvate
The title compound, [Zn3(C2H5)2(C6H5O3)4]·2C7H8, crystallizes with one complex mol-ecule solvated by two mol-ecules of toluene in the asymmetric unit. The Zn(II) ions are coordinated by two terminal ethyl (Et) groups and four maltolate ligands, which act as μ3- and μ2-bridges. The metal atoms are arranged in an incomplete cubane Zn3O4 core structure, derived from one EtZnO3 tetra-hedron, one Et...
متن کاملBis(acetylacetonato-κ2 O,O′)(2-amino-1-methyl-1H-benzimidazole-κN 3)oxidovanadium(IV)
The title mixed-ligand oxidovanadium(IV) compound, [VO(C(5)H(7)O(2))(2)(C(8)H(9)N(3))], contains a V(IV) atom in a distorted octahedral coordination, which is typical for such complexes. The vanadyl group and the N-heterocyclic ligand are cis to each other. The coordination bond is located at the endocyclic N atom of the benzimidazole ligand. Intra-molecular hydrogen bonds between the exo-NH(2)...
متن کاملEnhanced therapeutic effects of liposome-associated 1-O-octadecyl-2-O-methyl-sn-glycero-3-phosphocholine.
The ether-lipid 1-O-octadecyl-2-O-methyl-sn-glycero-3-phosphocholine (ET-18-OCH3) has anticancer activity, but systemic toxicity has restricted its therapeutic use. In this report "free" ET-18-OCH3 and a stable, well-characterized, liposome-based formulation of ET-18-OCH3 (ELL-12) were compared for in vivo toxicity in normal mice and for therapeutic efficacy in three mouse tumor model systems. ...
