The C-C bond formation is an important reaction in organic synthesis to obtain value-added intermediates. Therefore, in this paper an attempt has been made to accelerate the Henry reaction (C-C bond formation) between aryl aldehydes and nitromethane using less expensive whole cell biocatalyst, baker’s yeast (BY). The scope of the methodology was also tested for the heteryl aldehyde i.e. 2-chlor...

This chapter presents an overview of the chemistry and pharmacology of the alkaloids found in species of the Annonaceae family. The occurrence of alkaloids from Annonaceae species, as well as their chemical structures and pharmacological activities are summarized in informative and easy-to-understand tables. Within the Annonaceae family, the genera Annona, Duguetia, and Guatteria have led to ma...

This short note describes the synthesis of a novel compound, 6,6′-di-(8″-quinoline)-2,2′-bypyridine (2), that bears bipyridyl backbone and quinoline donors. Compound 2 coordinates with cobalt(II) ion in tetradentate manner affords complex [CoII(2)(TfO)2], whose molecular structure has been identified by single crystal X-ray diffraction crystallographic analysis. The coordination features were c...

Quinoline is a typical nitrogenous heterocyclic compound, which carcinogenic, teratogenic, and mutagenic to organisms, its wastewater difficult biodegrade directly. The bipolar electro-Fenton process was employed treat quinoline solution. process/reaction conditions were optimized through the single factor experiment. degradation kinetics of chemical oxygen demand (COD) analyzed. To get mechani...

Background: Alkaloids are a group of nitrogenous compounds with potential effects on the physiological behavior of human and animals. Some of these compounds are considered important drugs in modern medicine, such as atropine and morphine. Plants are considered the most important source of alkaloids. Therefore, investigating the presence of alkaloids in different plants is very important. Usual...

PREFACE The Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65, California Health and Safety Code 25249.5 et seq.) requires that the Governor cause to be published a list of those chemicals " known to the state " to cause cancer or reproductive toxicity. The Act specifies that " a chemical is known to the state to cause cancer or reproductive toxicity...if in the opinion of t...

Motivated by the observation that the Aspergillus nidulans genome bears multiple anthranilic acid synthase gene copies, the fungal metabolome was reinvestigated under various fermentation conditions, resulting in the discovery of novel prenylated quinolin-2-one alkaloids, two of which bear unprecedented terpenoid side chains.

The title compound, C24H18BrF3N4O4, is a 1,2,3-triazole derivative featuring, among others, a quinoline-derived substituent. In the crystal, C-H⋯O, C-H⋯N and C-H⋯F contacts connect the mol-ecules into a three-dimensional network. The shortest centroid-centroid distance between two aromatic systems is 3.896 (2) Å and is found between the two different six-membered rings of the quinoline scaffold...

Microbial infections are one of the leading diseases which are responsible for millions of deaths every year because of lack of effective antimicrobial therapy and this situation becomes more complicated because of microbial resistance towards conventional antibiotics. Quinoline derivatives have proved their medicinal importance by having broad spectrum of pharmacological activities like antimi...
