An effective synthesis of the mannose heptasaccharide existing in the pathogenic yeast, Candida glabrata IFO 0622 strain was achieved via TMSOTf-promoted condensation of a tetrasaccharide donor 13 with a trisaccharide acceptor 16, followed by deprotection. The tetrasaccharide 13 was constructed by coupling of 2,3,4,6-tetra-O-benzoyl-D-mannopyranosyl-(1 3)-2,4,6tri-O-acetyl-D-mannopyranosyl tric...

This paper presents the synthesis of silver nanoparticles (AgNPs) functionalized with fluorescent molecules, in particular xanthene-based dyes, i.e., fluorescein isothiocyanate (FITC, λmax = 485 nm) and rhodamine B (RITC, 555 nm). An in-depth characterization particle–dye systems, AgNPs–RITC AgNPs–FITC, is presented to evaluate their chemical structure optical properties due interaction between...

In the structure of the the title compound, C(15)H(14)ClNO, the N-H and C=O bonds are trans to each other and the amide O atom is anti to the ortho-Cl atom in the benzoyl ring. The amide group makes dihedral angles of 61.2 (6) and 42.2 (8)° with the benzoyl and aniline rings, respectively. In the crystal, the mol-ecules are linked into infinite chains by N-H⋯O hydrogen bonds.

In the title compound, C21H17N3O3S, the non-H atoms, apart from those in the benzoyl group, are almost coplanar (r.m.s. deviation = 0.049 Å) and the benzoyl group is almost orthogonal to the plane of the rest of the mol-ecule [dihedral angle = 80.34 (6)°]. In the crystal, a combination of N-H⋯O and asymmetric bifurcated O-H⋯(N,O) hydrogen bonds link the mol-ecules into a three-dimensional netwo...

In the mol-ecular structure of the title compound, C(15)H(14)ClNO, the amide group forms dihedral angles of 15.8 (2) and 27.2 (2)°, respectively, with the benzoyl and aniline rings, while the angle between the benzoyl and aniline rings is 11.5 (1)°. The crystal structure is stabilized by N-H⋯O hydrogen bonds, which give rise to infinite chains running along the c axis.

In the title compound C13H10ClN3O3S, the benzoyl group maintains its trans conformation against the thiono group about the C-N bond and the intra-molecular hydrogen bond between the benzoyl O atom and thio-amide H atom. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules, forming chains along the b-axis direction. In addition, C-H⋯π inter-actions occur between a phenyl H atom and...

In the title compound, C(14)H(12)ClNO(3)S, the N-H bond in the C-SO(2)-NH-C(O) segment is anti to the C=O bond. Further, the C=O bond and the meta-Cl atom in the benzoyl ring are also anti to each other. The dihedral angle between the sulfonyl and the benzoyl benzene rings is 72.4 (1)°. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers.

Phytochemical investigations on the stem bark and roots of the tropical shrub Clausena anisata led to the isolation and characterization three carbazole alkaloids: girinimbine, murrayamine-A and ekeberginine; two peptide derivatives: aurantiamide acetate and N-benzoyl-L-phenylalaninyl-N-benzoyl-L-phenylalaninate; and a mixture of two phytosterols: sitosterol and stigmasterol. The structures of ...

Benzoyl-CoA is the signature central metabolite associated with the anaerobic metabolism of a diverse range of compounds such as humic acid, lignin, amino acids, and industrial chemicals. Aromatic chemicals with different upstream degradation pathways all funnel into the downstream benzoyl-CoA pathway. Different genes encoding enzymes of the benzoyl-CoA pathway could be used as biomarkers for t...
