Piperazinyl oxazolidinone antibacterial agents containing a pyridine, diazene, or triazene heteroaromatic ring

Oxazolidinones are a novel class of synthetic antibacterial agents active against gram-positive organisms including methicillin-resistant Staphylococcus aureus as well as selected anaerobic organisms. Important representatives of this class include the morpholine derivative linezolid 2, which is currently in phase III clinical trials, and the piperazine derivative eperezolid 3. As part of an investigation of the structure- activity relationships of structurally related oxazolidinones, we have prepared and evaluated the antibacterial properties of a series of piperazinyl oxazolidinones in which the distal nitrogen of the piperazinyl ring is substituted with a six-membered heteroaromatic ring. Compounds having MIC values ? 2 mug/mL vs selected gram-positive pathogens were discovered among each of the pyridine, pyridazine, and pyrimidine structural classes. Among these the cyanopyridine 17, the pyridazines 25 and 26, and the pyrimidine 31 exhibited in vivo potency vs S. aureus comparable to that of linezolid.

Synthesis of N-(Hetero)aryl Carbamates via CuI/MNAO Catalyzed Cross-Coupling of (Hetero)aryl Halides with Potassium Cyanate in Alcohols

An efficient route to N-(hetero)aryl carbamates was developed through CuI/MNAO [2-((2-methylnaphthalen-1-yl)amino)-2-oxoacetic acid] catalyzed cross-coupling of (hetero)aryl chlorides with potassium cyanate in alcohols at 120-130 C. This method utilizes broadly available substrates to afford various N-(hetero)aryl carbamates in good to excellent yields. Moreover, (hetero)aryl bromides and (hetero)aryl iodides were also reacted at low catalyst loadings and relatively low temperatures to provide N-(hetero)aryl carbamates.

Dual-Element Isotope Analysis of Desphenylchloridazon to Investigate Its Environmental Fate in a Systematic Field Study: A Long-Term Lysimeter Experiment

Desphenylchloridazon (DPC), the main metabolite of the herbicide chloridazon (CLZ), is more water soluble and persistent than CLZ and frequently detected in water bodies. When assessing DPC transformation in the environment, results can be nonconclusive if based on concentration analysis alone because estimates may be confounded by simultaneous DPC formation from CLZ. This study investigated the fate of DPC by combining concentration-based methods with compound-specific C and N stable isotope analysis (CSIA). Additionally, DPC formation and transformation processes were experimentally deconvolved in a dedicated lysimeter study considering three scenarios. First, surface application of DPC enabled studying its degradation in the absence of CLZ. Here, CSIA provided evidence of two distinct DPC transformation processes: One shows significant changes only in 13C/12C, whereas the other involves changes in both 13C/12C and 15N/14N isotope ratios. Second, surface application of CLZ mimicked a realistic field scenario, showing that during DPC formation, 13C/12C ratios of DPC were depleted in 13C relative to CLZ, while 15N/14N ratios remained constant. Finally, CLZ depth injection simulated preferential flow and demonstrated the importance of the topsoil for retaining DPC. The combination of the lysimeter study with CSIA enabled insights into DPC transformation in the field that are superior to those of studies of concentration trends.

First synthesis of novel 3,3?-bipyridazine derivatives as new potent antihepatocellular carcinoma agents

Hepatocellular carcinoma is one of the most common kind of cancers in clinical, and its clinical treatment is quite difficult. The latest research suggests that pyridazinone with a novel molecular skeleton shows excellent activity against hepatocellular carcinoma in vitro and in vivo. Considering YHHU-759 as the leading compound for reasonable structure modification, a series of 3,3?-bipyridazine derivatives including 8 novel compounds in this study were designed, synthesized and screened for their anti-hepatoma activities against liver cancer cell lines SMMC-7721, BEL-7402 and QGY-7703 in vitro. The result shows that all of the 3,3?-bipyridazine derivatives have good anti-hepatoma activities.

Nitrile oxide [3+2] cycloaddition: Application to the synthesis of 6-substituted 3(2H)-pyridazinones and 6-substituted 4,5-dihydro-4-hydroxy-3(2H)-pyridazinones

An efficient method for the preparation of 6-substituted 3(2H)-pyridazinones and 6-substituted 4,5-dihydro-4-hydroxy-3(2H)-pyridazinones starting from 3,5-disubstituted 4,5-dihydroisoxazoles is described. N-O bond cleavage of the isoxazoline ring promoted by molybdenum hexacarbonyl or by catalytic hydrogenation afforded the alpha-hydroxy gamma-keto esters 4a-f which were converted into 6-substituted 4,5-dihydro-4-hydroxy-3(2H)-pyridazinones 5a-f or 6-substituted 3(2H)-pyridazinones 6a-f on treatment with hydrazine hydrate at room temperature or reflux in high yield starting from 4a-f. The flexibility of this protocol has been demonstrated by the synthesis of the C-nucleoside 7 starting from the known beta-ribofuranosylnitromethane 8. Moreover, an intramolecular version of this methodology has been developed to prepare the known antiulcer tricyclic 3(2H)-pyridazinone 12.
