Isoquinoline alkaloids isolated from three Guatteria species

The chemical investigation of the aerial parts of Guatteria ferruginea collected in the National Park of Serra dos Orgaos, Teresopolis, Brazil and of Guatteria latifolia and Guatteria sellowiana collected in the National Park of Itatiaia, Itatiaia, Brazil resulted in the isolation and identification of six isoquinoline alkaloids, two aporphine alkaloids 3-hydroxy-nornuciferine (1), nornuciferine (2) and four oxoaporphine alkaloids lysicamine (3), isomoschatoline (4), liriodenine (5) and O-methylmoschatoline (6). The isoquinoline alkaloids were found in the species G. ferruginea, G. latifolia and G. sellowiana for the first time and they support the taxonomic position within the genus Guatteria. Isoquinoline alkaloids (5-6) can be considered chemotaxonomic markers of the subfamily Annonoideae. (C) 2017 Elsevier Ltd. All rights reserved.

N-OXIDATION OF QUINOLINE AND ISOQUINOLINE BY CUNNINGHAMELLA-ELEGANS

Cultures of Cunninghamella elegans were grown for 7 days in liquid Sabouraud medium containing 1.9 mM quinoline or isoquinoline. The spent culture media were extracted with ethyl acetate; metabolites were purified by high-performance liquid chromatography (HPLC) and thin-layer chromatography. The major metabolite produced from each compound was identified by the HPLC elution time, ultraviolet/visible absorption spectrum, and mass spectrum. Under similar conditions, approximately 65% of the added quinoline and 3% of the added isoquinoline were metabolized to quinoline N-oxide and isoquinoline N-oxide, respectively.

Oxidative decarbonylative coupling of aliphatic aldehydes with methacryloyl benzamides to generate isoquinoline-1,3(2H,4H)-diones

Alkyl-substituted isoquinoline-1,3(2H,4H)-diones were prepared by decarbonylative coupling of N-alkyl-N-methacryloylbenzamides and aliphatic aldehydes under metal-free conditions. The reaction undergoes subsequent decarbonylation, radical addition and cyclization processes with aliphatic aldehydes as the cheap and abundant alkyl radical source. This procedure offers a complementary approach to the convenient generation of alkyl-substituted isoquinoline-1,3(2H,4H)-diones.

Cholinesterase inhibitory isoquinoline alkaloids from Corydalis mucronifera

Eight previously undescribed isoquinoline alkaloids, mucroniferanines H-M, together with 16 known isoquinoline alkaloids, were isolated from Corydalis mucronifera Maxim.. The structures of the previously undescribed compounds were elucidated by interpretation of 1D and 2D NMR spectroscopic and HAMS data, and their absolute configurations were established by computational electronic circular dichroism (ECD) calculations and X-ray diffraction data. Mucroniferanine L is reported as the first natural amide bond linked isoquinoline alkaloid dimer. The isolated compounds were evaluated for AChE and BuChE inhibitory activities and mucroniferanine H showed significant activities with IC50 values of 2.31 mu M and 36.71 mu M, respectively.

Isoquinoline N-Oxide Synthesis under Pd-Catalysed C-H Activation/Annulation Processes

An oxime directed C-H activation-annulation reaction for the selective synthesis of a range of isoquinoline N-oxides has been developed. Under palladium-catalyzed acid-assisted conditions, the reaction undergoes concerted metallation deprotonation followed by carbopalladation and transmetallation to give polysubstituted isoquinoline N-oxides in moderate to good yields.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Genetic aspects of the relationship between isoquinoline alkaloids and mineral elements in greater Celandine (Chelidonium majus L.)

Interrelations between the total content of isoquinoline alkaloids, the concentrations of quaternary protoberberines and benzophenanthridines, and the amount of K, Cu, Co, Al, Ba, and Zn in aerial parts of individual celandine plants were revealed, within a single cenopopulation, using correlation analysis and regression analysis. Mathematical models describing the regulation of isoquinoline metabolism by some of the mineral elements were obtained in analytical form. The results suggest that this process is genetically determined.

CRYSTAL-STRUCTURE OF ISOQUINOLINE – PICRIC ACID COMPLEX

The crystal structure of the isoquinoline:picric acid complex (C9H7N . C6H3N3O7) was determined by means of X-ray crystal analysis. A proton of the hydroxyl group of picric acid was transferred to the nitrogen atom of the isoquinoline molecule in the complex. Isoquinoline and picric acid molecules are arranged alternately along the b-axis, making their molecular planes parallel to each other in the crystal. They overlap each other, and isoquinoline picrate is formed through both ionic interaction and pi-bonding.

Synthesis and Photophysical Properties of 3-(Trifluoromethyl)-2H- imidazo[5,1-a]isoquinolinium Chloride Derivatives

A series of novel blue-light-emitting 2H-imidazo[5,1-a]isoquinolinium chloride derivatives were synthesized by the reaction of isoquinoline with trifluoroacetimidoyl chlorides and isocyanides in dry CH2Cl2 in excellent yields. Fluorescence studies showed that the compounds absorb UV radiation and then emit blue light at about 481 nm with moderate to good fluorescence quantum yields. These compounds also showed high Stokes shifts, and can be used to develop ultrasensitive fluorescent molecular probes to study a variety of biological events and processes.
