Bicyclic [b]-heteroannulated pyridazine derivatives. 10. Acid cleavage of some beta-keto esters in the reaction with 4,4-dimethyl- and 4-phenyltetrahydropyridazine-3,6-dione 3-hydrazones

4,4-Dimethyltetrahydropyridazine-3,6-dione 3-hydrazone (1) reacted with beta-keto esters in refluxing ethanol to give the acid cleavage products: 7,8-dihydro-3,8,8-trimethyl-triazolo[4,3-b]pyridazin-6(5H)-one (7) and esters 9. The yield of the reaction in most cases was nearly quantitative. At room temperature mostly the simple condensation products 4 were isolated. In analogous reactions, 4-phenyltetrahydropyridazine-3,6-dione 3-hydrazone (2) was found to be much less reactive. The hydrazone-ester condensation products 4 and some 5 were converted into the corresponding pyrazolylpyridazine derivatives 10 and 11, respectively, by heating above their melting points; the formation of 7 was noted in the reactions with 4. The results support the concept of different tautomeric preferences in 1 and 2.

Design and synthesis of dopaminergic agonists

The use of dopaminergic agonists is key in the treatment of Parkinson’s disease and related central nervous system (CNS) neurodegenerative disorders. Despite there are a number of commercialized dopaminergic agonists that are currently being used successfully in the first stages of the disease, they often fail to provide sustained clinical benefit for a long period due to the appearance of side-effects such as augmentation, sleepiness, nausea, hypothension, and compulsive behaviors among others. New dopaminergic agonists with less side effects are being developed. These novel compounds offer an alternative when the disease progresses and patients fail to respond to standard dopaminergic treatments or side-effects increased. Chemistry, and in particular chemical synthesis, has played a major role in bringing synthetic dopaminergic agonists to the clinic and continues to be crucial for the development of new and necessary drugs for long-term treatments with less undesired side effects. A number of structural modifications of parent compounds have led to enhanced agonism but also partial agonism or even antagonism of one or more dopamine receptors. In some cases, these activities are accompanied by agonist effect at serotonin receptors which suggests a potential clinical application in the treatment of schizophrenia In this review, chemical synthesis of dopaminergic agents, their affinity, and the corresponding agonist/antagonist effects will be highlighted.

Synthesis and spectroscopic properties of benzo- and naphthofuryl-3-hydroxychromones

With the focus of designing new fluorescent probes, four new 3-hydroxy-chromone derivatives bearing benzofuran and naphthofuran groups were synthesized. They show bathochromic absorption shifts relative to 3-hydroxyflavone with the ability of retention to display the excited-state proton transfer. Disruption of the planarity by the methyl group in the furan ring leads to a decrease of both the extinction coefficient and the contribution of long wavelength absorption band, while molecules without a methyl group showed two distinct absorption bands. Shifts to longer wavelengths are also observed in fluorescent spectra, and the absence of the methyl group results in a dramatic increase of fluorescence quantum yield and lifetime. Of the extended 3-hydroxychromone derivatives, 3-hydroxy-2-naphtho[2,1-b]furan-2-yl-chromone has shown comparable, and in some cases better, absorption and fluorescence properties than the 3-hydroxychromones synthesized so far, which make it a highly promising candidate as molecular probe for analytical chemistry, biophysics, and cellular biology.

Fungicidal Activity of Essential Oils from Cinnamomum cassia against the Pathogenic Fungi of Panax notoginseng Diseases

The frequent disease of Panax notoginseng caused by the pathogenic fungi in field cultivation has become the major threaten to the sustainable development of it. The present study was conducted to find natural agent with potential inhibition against pathogen. Therefore, the inhibitory effects of Cinnamomum cassia (L.) J.Presl essential oils (EOs) against P. notoginseng associated pathogenic fungi were conducted both in vitro and in vivo experiments. The results of the Oxford cup test revealed that C. cassia dry bark EO (50 mg/mL) had significant inhibitory activity on the growth of all tested fungi, and the growth of various pathogens was completely inhibited, except for that of Fusarium solani. Therefore, the constituents of C. cassia EOs were analyzed by GC/MS, and the research demonstrated that the main constituents of C. cassia dry bark EO were trans-cinnamaldehyde (75.65 %), (E)-2-methoxycinnamaldehyde (6.08 %), cinnamaldehyde (3.47 %) and cinnamyl acetate (1.02 %). The MIC results showed that C. cassia dry bark EO and the main compounds had good antifungal effect on the tested strains, and the inhibitory effect was similar to that of hymexazol (chemical pesticide). By analyzing the value of the fraction inhibitory concentration index (FICI), additive effects, irrelevant effects and synergistic effects were observed after the mixture of hymexazol against various pathogens. Moreover, in vivo model showed that C. cassia dry bark EO could reduce the occurrence of anthrax in P. notoginseng. To widen the resources of C. cassia available, the compositions of both C. cassia fresh bark and leaf EOs were also tested and many common compositions existed among them. Taken together, it was concluded that C. cassia EO had the potential use in the field to reduce the pathogenic disease.

Optimization of solar photocatalytic degradation conditions of bisphenol A in water using titanium dioxide

The photocatalytic degradation conditions of 4,4?-isopropylidenediphenol (bisphenol A, BPA), a representative endocrine disruptor, in water using titanium dioxide were optimized under sunlight illumination. The effect of various factors, such as photocatalyst dosage, initial substrate concentration, temperature, pH and light intensity, on the photocatalytic degradation of bisphenol A was investigated. The final degradation product was carbon dioxide, and the stoichiometric formation of CO2 from aqueous bisphenol A solution was observed as the complete mineralization. The solar photocatalytic degradation treatment is simple, easy handling and cheap. Therefore, since the artificial lamp devices, for example Hg-Xe lamp, are particularly expensive in the local and nonexclusive areas, the proposed technique appears to be a very suitable method for the treatment of wastewater including bisphenol A in those areas.

N-doped graphitic carbon-improved Co-MoO3 catalysts on ordered mesoporous SBA-15 for chemoselective reduction of nitroarenes

Metallic Co-MoO3 catalysts supported on ordered mesoporous SBA-15 were first prepared through in situ reaction of SBA-15-supported Co-Mo oxides with 1,10-phenanthroline. The resulting Co-MoO3/NC@SBA-15 catalysts with N-doped carbon (NC) exhibited high catalytic activity and chemoselectivity for selective reduction of various functionalized nitroarenes to the corresponding arylamines in ethanol with hydrazine hydrate at near room temperature (30 C). For reduction of all tested substrates (28 examples), the catalyst could afford a conversion of >99% and arylamine selectivity of >99%. The excellent catalytic performance of the Co-MoO3/NC@SBA-15 was attributed to the Co-Nchi(C)-Mo active sites generated through the interaction between the surface Co-Nchi(C) and MoO3 species, promoting the dissociation of hydrazine molecule into the active H* species for the reduction of nitro groups. After the seventh cycle for reduction of 4-methoxylnitrobenzene, the 2%Co-MoO3/NC@SBA-15 showed little change in catalytic performance, textural properties, size and dispersion of metal species and valence states of elements, indicating high stability and recyclability.
