Antimalarial benzoquinones from an endophytic fungus, Xylaria sp.
Two novel benzoquinone metabolites, 2-chloro-5-methoxy-3-methylcyclohexa-2,5-diene-1,4-dione ( 1) and xylariaquinone A ( 2) together with two known compounds were isolated from an endophytic fungus,Expand
Crystal structure of β-cyclodextrin–dimethylsulfoxide inclusion complex
beta-Cyclodextrin (beta-CD) crystallizes from 27% DMSO-water as beta-CD.0.5DMSO.7.35H(2)O in the monoclinic space group P2(1) with unit cell constants: a=15.155(1), b=10.285(1), c=20.906(1) A,Expand
Hectochlorin and morpholine derivatives from the Thai sea hare, Bursatella leachii.
Investigation of the EtOAc extract from the Thai sea hare resulted in the isolation of a potent stimulator of actin assembly, hectochlorin, and its new derivative, deacetylhectochlorIn, which exhibited more potent cytotoxicity than 1 against different human carcinoma cell lines. Expand
New ferromagnetic dinuclear triply-bridged copper(II) compounds containing carboxylato bridges: Synthesis, X-ray structure and magnetic properties
Abstract The new triply-bridged dinuclear copper(II) complexes, [Cu2(μ-O2CH)(μ-OH)2(dpyam)2](ClO4) · H2O (1), [Cu2(μ-O2CCH3)(μ-OH)(μ-OH2)(dpyam)2](S2O8) (2), [Cu2(μ-O2CCH3)(μ-OH)(μ-OH2)(bpy)2](NO3)2Expand
Solvent-assisted mechanochemical synthesis of metal complexes.
The application of solvent-assisted mechanochemical synthesis to the study of metal complex formation is illustrated by examples involving complexes of silver halides with ethylenethiourea.
New orthorhombic form of 2-[(2,6-dichlorophenyl)amino]benzeneacetic acid (diclofenac acid).
A new orthorhombic form of diclofenac acid (HD3) with the space group Pcan is reported on, which is a non-steroidal anti-flammatory drug and refined with anisotropic displacement parameters for all non-hydrogen atoms by full-matrix least-squares using the SHELX-97 package for PC. Expand
Croblongifolin, a new anticancer clerodane from Croton oblongifolius.
Croblongifolin showed a significant cytotoxicity against various human tumor cell lines including HEP-G2, SW620, CHAGO, KATO3 and BT474. Expand
Biotransformation of ent-kaur-16-en-19-oic acid by Absidia blakesleeana and Rhizopus oligosporus
Biotransformation of ent-kaur-16-en-19-oic acid was carried out with Absidia blakesleeana and Rhizopus oligosporus and produced two novel metabolites. Expand
Inclusion complexes of β-cyclodextrin with pyrazinamide and piperazine: Crystallographic and theoretical studies
The inclusion complexes of β-cyclodextrin (β-CD) with pyrazinamide (PYA) and piperazine (PIZ) have been investigated both in the solid phase by single-crystal X-ray diffraction analysis and in theExpand
Crystal structure of beta-cyclodextrin-benzoic acid inclusion complex.
The inclusion complex of beta-cyclodextrin (beta-CD) with benzoic acid (BA) has been characterized crystallographically and the anisotropic refinement of 1840 atomic parameters against 16,201 X-ray diffraction data converged at R=0.078. Expand
