N'-(2-hydroxy-3-methoxybenzylidene)-4-methylbenzenesulfonohydrazide (1) was prepared by the reaction of p-Toluenesulfonyl hydrazide and 2-hydroxy-3-methoxy benzaldehyde (1:1 molar ratio) in ethanol under reflux condition. The crystal structure of the compound was determined by X-ray crystallography. Crystal data for 1 at -100 K: space group C/2c with: a = 15.807(1) Å, b = 10.457(1) Å, c = 20.77...
A new anthracene derivative, 3-hydroxy-1-keto-3-methyl-8-methoxy-1,2,3, 4-tetrahydro-benz[α]anthracene, was isolated from the marine strain Streptomyces sp. W007, and its structure was established by spectroscopic analysis including mass spectra, 1D- and 2D-NMR ((1)H-(1)H COSY, HMBC, HSQC and NOESY) experiments. 3-hydroxy-1-keto-3-methyl-8-methoxy-1,2,3,4-tetrahydro-benz[α]anthracene showed cyt...
Some meso-tetra aryl porphyrinato manganese (III) acetate or chloride complexes including meso-tetraphenyl porphyrinato manganese (III) chloride (TPPMnCl), meso-tetrakis(2,3-dimethoxyphenyl)porphyrinato manganese(III) acetate, (T(2,3-OMeP)PMnOAc) and meso-tetrakis(pentaflourophenyl)porphyrinato manganese (III) acetate (TPFPPMnOAc) were synthesized. These porphyrins were used as catalyst in the ...
This study describes the organic synthesis of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxy benzofuran-6-ol (SPBF) as an example of a benzofuran derivative used as a new series of amyloid imaging agents. These benzofuran derivatives may be useful amyloid imaging agents for detecting B-amyloid plagues in the brain of Alzheimer’s disease. The precursor is 1-[6-hydroxy-4-methoxybenzofuran-5-yl]-p...
objective: the genus of ferula belongs to the tribe peucedaneae, subfamily of apioideae and family of umbelliferae with 133 species distributed throughout the mediterranean area and central asia, especially in the former ussr and neighboring countries such as iran. the popular persian name of the most of these species is “koma”. in this research we tried to isolate and elucidate the structure o...
A microwave-assisted synthesis of 2-(4-((1-phenyl-1H-1,2,3-triazol-4-yl)methoxy)phenyl)-1H-benzo[d]imidazoles from a phenylazide, propargyloxybenzaldehyde and a 1,2-diaminobenzene is proposed.
The title compound, C(20)H(12)Cl(3)N(3)O(2), was synthesized by the reaction of 2-(2-hydroxy-phen-yl)benz[e][1,3]oxazin-4-one with 2,4,6-trichloro-phenyl-hydrazine in ethanol. The trichloro-phenyl ring is nearly perpendicular to the triazole plane [dihedral angle 80.56 (8)°], whereas the two hydroxy-phenyl rings are approximately coplanar with the triazole ring [dihedral angles of 2.79 (12) and...
Biofilm formation and adherence of bacteria to host tissue are one of the most important virulence factors of methicillin-resistant strains of Staphylococcus aureus (MRSA). The number of resistant strains is seriously increasing during the past years and bacteria have become resistant, not only to methicillin, but also to other commonly used antistaphylococcal antibiotics. There is a great need...
