Copper-Catalyzed [4+2]-Cycloadditions of Isoxazoles with 2-Alkynylbenzaldehydes To Access Distinct alpha-Carbonylnaphthalene Derivatives: C(3,4)-versus C(4,5)-Regioselectivity at Isoxazoles

Cu(II)-catalyzed [4+2]-cycloadditions occur between Cu-benzopyryliums and substituted isoxazoles with the regioselectivity on the C(3,4)-carbons of isoxazoles. We postulate that a prior coordination of isoxazoles with Cu(OAc)2 increases the I-bond character of the C(3,4) carbons to become an effective 2I-donor. In this reaction sequence, 3,5-disubstituted isoxazoles yield alpha,I-dicarbonylnaphthalenes whereas, 5-substituted isoxazoles deliver alpha,I-dicarbonyl-beta-aminonaphthalenes. For unsubstituted isoxazole, its cycloaddition chemoselectivity is switched to the C(4,5)-addition regioselectivity to yield alpha-carbonyl-I-cyanonaphthalene derivatives.

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 300-87-8 is helpful to your research. Application of 300-87-8

Synthetic and medicinal prospective of structurally modified curcumins

Curcumin, a natural yellow phenolic compound, is present in various types of herbs, particularly in Turmeric, Curcuma longa Linn. (Zingiberaceae family) rhizomes. Curcumin is a polyphenolic natural compound with diverse and attractive biological activities. In the last decade curcumine and its various synthetic analogues have been prepared and evaluated for various pharmacological activities that prove it as a lead molecule against several biological targets. It is a natural antioxidant and exhibited many pharmacological activities such as anti-inflammatory, anti-microbial, anticancer, anti-Alzheimer in both preclinical and clinical studies. Moreover, Curcumin and its analogues have anti-tubercular, cardioprotective, anti-diabetic, hepatoprotective, neuroprotective, nephroprotective, antirheumatic and anti-viral activities. The substitutions of 1,6-heptadiene linkage moiety via carbonyl group sustituion and addition of heterocyclic linker; isoxazole, 1H-pyrazole, cyclopentanone, piperidin-4-one, N-methylpiperidin-4-one enhance biological activities. The structure activity relationship of various curcumin analogues is studied for medicinal purposes and it reveals that monocarbonyl linkage analogues have anticancer properties. The current review gives an insight of the history, chemistry, analogues and most interesting in vitro and in vivo studies on the biological effects of Curcumin and its analogues.

Non-acidic 1,3,4-trisubstituted-pyrazole derivatives as lonazolac analogs with promising COX-2 selectivity, anti-inflammatory activity and gastric safety profile

Twelve new compounds of 1,3,4-trisubstituted-pyrazole derivatives possessing two cyclooxygenase-2 (COX-2) pharmacophoric moieties (SO2Me or/and SO2NH2) 11a-c, 12a-c, 13a-c and 14a-c were designed and synthesized to be evaluated for their COX inhibition, anti-inflammatory activity, ulcerogenic liability. All compounds were more selective for COX-2 isozyme and showed good in vivo anti-inflammatory activity. The bisaminosulphonyl derivatives (14a-c) were the most COX-2 selective compounds (S.I. = 9.87, 9.50 and 9.22 respectively) and showed good anti-inflammatory potency (ED50 = 15.06, 42.51 and 50.43 mumol/kg respectively) in comparison with celecoxib (COX-2 S.I. = 8.61, ED50 = 82.2 mumol/kg). Also, compounds 14a-c were less ulcerogenic (ulcer indexes = 2.72?3.72) than ibuprofen (ulcer index = 20.25) and comparable to celecoxib (ulcer index = 2.93). In addition, to explain the preferential (COX-2) inhibitory and selectivity, the designed compounds were subjected to molecular docking studies. It was found that compound 14c with the highest COX-2 activity and selectivity exhibited a binding pattern and interactions similar to that of celecoxib with formation of more hydrogen-bond features.

Biodiversity, isolation and genome analysis of sulfamethazine-degrading bacteria using high-throughput analysis

Sulfamethazine (SM2) is one of the sulfonamide antibiotics that is frequently detected in aquatic environment. Given the complex structure of SM2 and its potential threat to the environment, it is necessary to determine the degradation behavior of high-concentration SM2. The mechanisms of community structure and diversity of activated sludge were analyzed. A novel SM2-degrading strain YL1 was isolated which can degrade SM2 with high concentration of 100?mg?L?1. Strain YL1 was identified as Paenarthrobacter ureafaciens and there was also a significant increase in the genus during acclimation. Additional SM2 metabolic mechanisms and genomic information of YL1 were analyzed for further research. The succession of the community structure also investigated the effect of SM2 on the activated sludge. This result not only advances the current understanding of microbial ecology in activated sludge, but also has practical implications for the design and operation of the environmental bioprocesses for treatment of antimicrobial-bearing waste streams.

3-Alkylperoxy-3-cyano-oxindoles from 2-Cyano-2-diazo-N-phenyl-acetamides via Cyclizing Carbene Insertion and Subsequent Radical Oxidation

A transition-metal-free one-pot sequence for the synthesis of 3-peroxy-substituted oxindoles from readily prepared 2-cyano-2-diazo-acetamides is reported. The two-step tandem process includes a highly efficient thermal intramolecular C-H-carbene insertion followed by a tetrabutylammonium iodide (TBAI) catalyzed radical C3-peroxy-functionalization. The protocol provides easy access to a new class of 3-cyano-3-peroxy-disubstituted oxindoles. Useful transformations to amides and alcohols are demonstrated.

Bispidine as a privileged scaffold

The diazabicyclic molecule bispidine named by the chemist Carl Mannich in 1930, is a naturally occurring scaffold with interesting features. Bispidine can form different conformers, has high basicity, can attack dichloromethane, has metal ion coordination properties and interacts with nicotinic acetylcholine receptors. In this review we will discuss important properties, synthetic pathways and biological activities of bispidine and some derivatives. Bispidine can function as a scaffold for compounds with very diverse biological activities, e.g. interacting with ion channels, G-protein coupled receptors, and enzymes, and is even used for the development of new in vivo radiotracers.
