Three efficient methods to synthesize mono- and di-fluorinated benzimidazoles are reported. These methods provide 5-amino-6-fluoro- benzimidazoles (5), 5,7-difluoro-benzimidazoles (10), and 6-fluoro- benzimidazoles (13) starting from commercially available 1,5-difluoro-2,4- dinitrobenzene (DFDNB), 2,3,4,5-tetrafluoro-6-nitrobenzoic acid (TFNBA), and 2,4-difluoro-1-nitrobenzene (DFNB), respectively.

Two novel series of spirocyclic piperidine analogs appended to a pyrazolo[1,5-a]pyridine core were designed, synthesized and evaluated for their anti-HCV activity. A series of piperidine ketals afforded dispiro 6p which showed excellent in vitro anti-HCV activities (EC50 of 1.5 nM and 1.2 nM against genotype 1a and 1b replicons, respectively). A series of piperidine oxazolidinones afforded 27c which showed EC50’s of 10.9 nM and 6.1 nM against 1a and 1b replicons, respectively. Both compounds 6p and 27c bound directly to non-structural NS4B protein in vitro (IC50’s = 10.2 and 30.4 nM, respectively) and exhibited reduced potency in replicons containing resistance mutations encoding changes in the NS4B protein.

A practical solid-phase synthesis that simply uses Rink amide resin as an amine component in reacting with aromatic isothiocyanates and aliphatic amines to generate disubstituted guanidines is described. No special linker or guanylation reagents are involved in this method. The product is obtained in a ‘traceless-linker’ fashion and in high yield and purity when an electron-deficient isothiocyanate is employed.

Chemistry is traditionally divided into organic and inorganic chemistry. name: N,N-Dimethylpiperidin-4-amine. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 50533-97-6

A novel series of 2-(6-alkyl-pyrazin-2-yl)-1H-benzo[d]imidazole analogs (3a?3j) derived from 2-(6-chloropyrazin-2-yl)-1H-benzo[d]imidazole (2) by reacting with various substituted cyclic and acyclic secondary amines in presence of Pd-PEPPSI Mes catalyst by using Buchwald?Hartwig amination in excellent yield. The structures of newly synthesized compounds were elucidated by Fourier transform infrared spectroscopy, 1H-nuclear magnetic resonance, 13C-nuclear magnetic resonance, electrospray ionisation mass spectrometry and high-resolution mass spectrometry spectral data. All the title compounds (3a?3j) were evaluated for in vitro screening against cyclooxygenase-1 and cyclooxygenase-2 by colorimetric COX (human ovine) inhibition assay and in vivo anti-inflammatory activity against cyclooxygenase-2 enzyme by means of the carrageenan-induced rat paw edema. The compound 3i was found to have potent anti-inflammatory activity than standard Ibuprofen. The compounds 3a, 3e, and 3j showed appreciable activity against cyclooxygenase-2 enzyme. However the compounds 3a, 3e, 3g, 3h, and 3j were showed maximum activity within 15 to 24 h and 3g and 3i were showed good DPPH scavenging activity. Moreover, the docking studies were also performed and the results are well agreement with the biological data, suggested that compound 3i was a potential anti-inflammatory agent for further development.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: N,N-Dimethylpiperidin-4-amine, you can also check out more blogs about50533-97-6

A new series of 12-benzyl matrinic amide/ethanamide derivatives were synthesized from matrinine (1) and evaluated for their anti-HCV activity, taking compound 2 as the lead. SAR revealed that the introduction of a suitable substituent at the N?-end of matrinic amide might greatly enhance the potency. Among them, matrinic acid 17 and N?-substituted matrinic amides 18a?d exhibited promising potency with low micromolar EC50values ranging from 1.03 mumol/L to 7.54 mumol/L, and better therapeutic window with SI from 66 to 132. Moreover, compound 17 displayed an excellent PK and safety profile in vivo, demonstrating good drug-like characteristics. Thus, it has been selected for further investigation, with an advantage of decreased chances of inducing drug-resistance mutations.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 73874-95-0 is helpful to your research. Recommanded Product: tert-Butyl piperidin-4-ylcarbamate

A new series of silicon(IV) phthalocyanines (SiPcs) axially di-substituted with piperidinyl moieties (compounds 1, 2a, and 3a) and their N-methylated derivatives (compounds 2b and 3b) have been synthesized and characterized. Meanwhile, an analogue di-substituted with cyclohexyl groups (compound 4) has also been prepared as a control. The antifungal photoactivities of these SiPcs toward Candida albicans were found to follow the order: 2b > 3a ? 3b > 1 ? 2a > 4. The structure-activity relationship of these phthalocyanines has been discussed by investigating their photophysical and photochemical properties, partition coefficient, and cellular uptake. The cationic phthalocyanine 2b shows the highest photodynamic activity against C. albicans causing 4 log10 reduction of this fungus at 100 muM, which could be attributed to its high singlet oxygen yields, less aggregation in aqueous media, and relatively efficient cellular uptake.
