Starting from D-mannose, D-glucose and L-fucose, the pentasaccharide derivative methyl 2,3,4-tri-O-benzyl-alpha-L-fucopyranosyl-(1-->3)-2-O-acetyl-4,6-O-benzylidene-alpha-D-mannopyranosyl-(1-->3)-2-O-acetyl-6-O-benzyl-4-O-(2,3,4-tri-O-benzyl-alpha-L-fucopyranosyl)-alpha-D-mannopyranosyl-(1-->4)-[2-(trimethylsilyl)ethyl 2,3-di-O-benzyl-beta-D-glucopyranosid]uronate was synthesized. This compound...

Several haloperidol derivatives with a piperidine scaffold that was decorated at the nitrogen atom with different alkyl, benzyl, or substituted benzyl moieties were synthesized at our laboratory to establish a library of compounds with vasodilator activity. Compounds were screened for vasodilatory activity on isolated thoracic aorta rings from rats, and their quantitative structure-activity rel...

Campylobacter jejuni is a widespread pathogen responsible for most of the food-borne gastrointestinal diseases in Europe. The use of natural antimicrobial molecules is a promising alternative to antibiotic treatments for pathogen control in the food industry. Isothiocyanates are natural antimicrobial compounds, which also display anticancer activity. Several studies described the chemoprotectiv...

The metabolism and cytotoxicity of benzyl 1,2,3,4,4-pentachlorobuta-1,3-dienyl sulfide (1) and benzyl 2-chloro-1,1,2-trifluoroethyl sulfide (2) were studied as an alternative test of the hypothesis that the toxicity of the cysteine S-conjugates S-(pentachlorobutadienyl)-L-cysteine and S-(2-chloro-1,1,2-trifluoroethyl)-L-cysteine is associated with their metabolism to unstable thiols; the expect...

the aim of this study was to evaluate the physiological and morphological characteristics of narcissus tazatta in response to benzyl adenine (ba) and nano-potassium fertilizer. this experiment was done as factorial with two factors of benzyl adenine hormone and nano-potassium fertilizer in a completely randomized design with ten replications.  benzyl adenine in four levels (0, 500, 750 and1000 ...

The catalytic activity of Pt/CNT for benzyl alcohol aerobic oxidation was remarkably improved by decorating iron oxide on Pt nanoparticles, and electrochemical measurements evidenced the enhanced activation of oxygen and benzyl alcohol at the FeO(x)/Pt interface.

four amidine nr2b-selective nmda receptor antagonists, n-( 2-methoxy benzyl) -3-phenyl-acrylamidine, n-[diduterio(2-methoxyphenyl) methyl]-3-phenyl-acrylamidine, n-benzyl-3-phenyl-acryl amidine and n-[diduterio(phenyl)methyl]-3-phenyl-acrylamidine, all fourlabeled with carbon-14 in the 1-position, have been synthesized as part of 5-step sequence fromba14co3.

The dielectric relaxation of benzyl alcohol substitutents (benzyl alcohol, m-methylbenzyl alcohol and m-nitrobenzyl alcohol) with methyl methacrylate and butyl methacrylate in dilute solution of carbon tetrachloride is measured at 9.37 GHz using Frequency domain (X-band) technique. Different dielectric parameters like dielectric constant (ε'), dielectric loss factor (ε'') at Microwave frequency...

We herein described the synthesis of several 3-benzyl-2,5-diarylselenophene derivatives in moderate to good yields using (Z)-benzylselenoenynes as starting material in carbocyclization reactions. The reactions were carried out under mild conditions using only t-BuOK as base, in the complete absence of transition metals or additives. The cyclized 3-benzyl-2,5-diarylselenophenes obtained in the c...

We report on the preparation of 4-aza-5,6-dimethylbenzimidazolylcobamide and 5,6-dimethyl-7-azabenzimidazolylcobamide. These vitamin B12-analogs were required as reference compounds for comparison with a corrinoid previously isolated in small amounts for Eubacterium limosum grown in the presence of 4(5)-aminoimidazole. 4(7)-Aza-5,6-dimethylbenzimidazole was synthesized from N-1-benzyl-4-nitroim...
