Two new sesquiterpene alkaloids, 1beta-hydroxy-2beta,5alpha,11-triacetoxy-7beta-nicotinoyl-8beta-benzoyl-dihydroagarofuran, and 1beta,5alpha,11-triacetoxy-7beta-nicotinoyl-8beta-benzoyl-dihydroagarofuran were isolated from the xylem of Tripterygium wilfordii, together with six known compounds. Their structures were elucidated on the basis of spectroscopic studies.

We demonstrate a photochemical reaction between graphene and benzoyl peroxide. This reaction introduces spatially localized defects into the graphene basal plane. The reactivity of the single-layer graphene is approximately 14 times higher than that of the double-layer graphene. Our result suggests that photoexcited graphene transfers a hot electron to benzoyl peroxide and induces its decomposi...

A new resorufin-based probe is developed, which exhibits a rapid and sensitive color and a fluorescence off-on response to benzoyl peroxide (BPO) in aqueous media containing 10% ethanol via deboronation. The probe has been applied to the simple detection of BPO in real samples such as wheat flour and antimicrobial agent.

IN THE TITLE COMPOUND (SYSTEMATIC NAME {[(phenyl-formamido)-carbon-yl]amino}-methane-thio-amide), C9H9N3O2S, both benzoyl and terminal thio-urea fragments adopt transoid conformations with respect to the central carbonyl O atom. The benzoyl and thio-biuret groups are almost coplanar, making a dihedral angle of 4.40 (8)°. The mol-ecular structure is stabilized by two intra-molecular N-H⋯O hydrog...

In the title compound, C(14)H(13)NO(3)S, the conformation of the N-H bond in the C-SO(2)-NH-C(O) segment is anti to the C=O bond. The tolyl and benzoyl groups are twisted about the S-N bond, with a C-S-N-C torsion angle of 68.8 (4)°. The dihedral angle between the sulfonyl and the benzoyl benzene rings is 73.9 (1)°. In the crystal, the mol-ecules are linked into C(4) chains along the c axis by ...

Capparis cartilaginea and C. deserti growing in Egypt were investigated for their glucosiolates and rutin content. From Capparis cartilaginea four isothiocynates were isolated and identified using GC and EI/MS techniques. These compounds were butyl isothiocyanate (1), 6-methylsulphonylhexyl isothiocyanate (2), 7-methylsulphonylheptyl isothiocyanate (3) and 5-benzylsulphonyl-4-pentenyl isothiocy...

   The aim of the present study was to synthesis a series of phthalimides based on our previous works and examine their anxiolytic properties. Using a three steps process, phthalimides were prepared from the corresponding di-methyl phthalate derivatives. Phthalic anhydride was nitrated to produce 3-nitrophthalic acid. Ring closer of either 3-nitrophthalic acid or di-methyl phthalate with urea w...

The N-(2-benzoyl-phenyl) oxalyl derivatives are important models for studying of three-centered intramolecular hydrogen bonding in organic molecules. The quantum theoretical calculations for two crystal structures of N-(2-benzoyl-phenyl) oxalyl (compounds I and II) were performed by Density Functional Theory (B3LYP method and 6-311+G* basis set). From the optimized structures, geometric paramet...

The pungent natural compound allyl isothiocyanate isolated from the seeds of Cruciferous (Brassica) plants such as mustard is reported to exhibit numerous beneficial health-promoting antimicrobial, antifungal, anticarcinogenic, cardioprotective, and neuroprotective properties. Because it is also reported to damage DNA and is toxic to aquatic organisms, the objective of the present study was to ...

A series of five-membered heterocyclic rings were synthesized by the reaction between benzoyl chloride and various chlolro-nitro-benzoyl chlorides and semi carbazide to form (C1-C7) compounds and was tested for their anti-inflammatory activity determined by rat-paw-oedema method. All the synthesis compounds have been characterized by 1HNMR, IR and Mass spectral data. The compounds were purified...
