3-Deoxy-DL-prumycin (1) was synthesized from 2-furanmethanol (2-furfuryl alcohol, 2) in eleven steps in 15% total yield. Michael addition of azide anion to 2,3-dideoxy-DL-pent-2-enopyranos-4-ulose (3) and reduction in situ of the adduct afforded the key intermediates 5 and 6. Introduction of a second azido group with inversion of configuration at C-4 afforded intermediates 14 and 17, both of wich had a threo configuration in regard to C-2 and C-4. Coupling with D-alanine and total deprotection yielded the title compound 1. 3-Deoxy-DL-prumycin (1) was synthesized from 2-furanmethanol (2-furfuryl alcohol, 2) in eleven steps in 15% total yield.

The synthesis and pharmacological activity of a series of bicyclic pyrazolo[1,5-alpha]pyrimidines as potent and selective cyclooxygenase-2 (COX-2) inhibitors are described. The new compounds were evaluated both in vitro (COX-1 and COX-2 inhibition in human whole blood) and in vivo (carrageenan-induced paw edema and air-pouch model). Modification of the pyrimidine substituents showed that 6,7-disubstitution provided the best activity and led to the identification of 3-(4-fluorophenyl)-6,7-dimethyl-2-(4-methylsulfonylphenyl) pyrazolo[1,5-alpha]pyrimidine (10f) as one of the most potent and selective COX-2 inhibitor in this series.

A series of exceptionally potent agonists at neuronal nicotinic acetylcholine receptors (nAChRs) has been investigated. Several N-(3-pyridinyl) derivatives of bridged bicyclic diamines exhibit double-digit-picomolar binding affinities for the alpha4beta2 subtype, placing them with epibatidine among the most potent nAChR ligands described to date. Structure-activity studies have revealed that substitutions, particularly hydrophilic groups in the pyridine 5-position, differentially modulate the agonist activity at ganglionic vs central nAChR subtypes, so that improved subtype selectivity can be demonstrated in vitro. Analgesic efficacy has been achieved across a broad range of pain states, including rodent models of acute thermal nociception, persistent pain, and neuropathic allodynia. Unfortunately, the hydrophilic pyridine substituents that were shown to enhance agonist selectivity for central nAChRs in vitro tend to limit CNS penetration in vivo, so that analgesic efficacy with an improved therapeutic window was not realized with those compounds.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Recommanded Product: 3-Phenyl-6-chloropyridazine. Introducing a new discovery about 20375-65-9, Name is 3-Phenyl-6-chloropyridazine

A series of dual-target AChE/PDE9A inhibitor compounds were designed, synthesized, and evaluated as anti-Alzheimer’s Disease (AD) agents. Among these target compounds, 11a (AChE: IC50 = 0.048 muM; PDE9A: IC50 = 0.530 muM) and 11b (AChE: IC50 = 0.223 muM; PDE9A: IC50 = 0.285 muM) exhibited excellent and balanced dual-target AChE/PDE9A inhibitory activities. Meanwhile, those two compounds possess good blood-brain barrier (BBB) penetrability and low neurotoxicity. Especially, 11a and 11b could ameliorate learning deficits induced by scopolamine (Scop). Moreover, 11a could also improve cognitive and spatial memory in Abeta25-35-induced cognitive deficit mice in the Morris water-maze test. In summary, our research developed a series of potential dual-target AChE/PDE9A inhibitors, and the data indicated that 11a was a promising candidate drug for the treatment of AD.

Benzylidenehydrazinyl imidazoles (3) are prepared from 2-hydrazinyl imidazoles (2) on treatment with hydrazine. The imine functionality in 3 is utilized to develop 5?-aryl-N-(4-aryl-1H-imidazol-2-yl)-1H-1,2,3-triazol-1-amines (5) by 1,3-dipolar cycloaddition of diazomethane followed by aromatization with I2 in DMSO. Compounds 3 are also explored to prepare 4?-aryl-1-(4-aryl-1H-imidazol-2-ylamino)-3-chloroazetidin-2-ones (6) on treatment with chloroacetyl chloride. The Molinspiration calculations predicted that 3, 5 and 6 have molecular hydrophobicity, conformational flexibility, good intestinal absorption and bioactivity scores. The chloro, bromo and nitro substituted imidazolyl azetidinones (6c, 6d, 6f) and nitro substituted imidazolyl triazole (5f) exhibited excellent antibacterial activity on B. subtilis, whereas chloro and nitro substituted imidazolyl triazoles (5c, 5f) showed prominent antifungal activity on A. niger.
