A rapid, easy, and efficient method for synthesis of 4,4'-(arylmethylene)-bis-(1H-pyrazol-5-ols), catalyzed by boehmite nanoparticles [PDF]

open access: yesشیمی کاربردی روز, 2016
An efficient and eco-friendly method is introduced for the synthesis of 4,4'-(arylmethylene)-bis-(1H-pyrazol-5-ols) by the condensation reaction of two equivalents of 5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one with various aromatic aldehydes ...

The role of lipid metabolism in neuronal senescence

open access: yesFEBS Open Bio, EarlyView.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

Microwave-assisted practical and simple method for heterocyclization of o-phenylenediamine and aldehydes using DDQ as oxidant agent

open access: yesGreen Chemistry Letters and Reviews, 2017
In this research, 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) has been used in the condensation reaction between o-phenylenediamine and various arylaldehydes as oxidants under microwave irradiation.

The effect of host structure on the selectivity and mechanism of supramolecular catalysis of Prins cyclizations. [PDF]

open access: yes, 2015
The effect of host structure on the selectivity and mechanism of intramolecular Prins reactions is evaluated using K12Ga4L6 tetrahedral catalysts. The host structure was varied by modifying the structure of the chelating moieties and the size of the ...

Alcohol‐induced altered glycans in human tracheal epithelial cells promote bacterial adhesion

open access: yesFEBS Open Bio, EarlyView.
Alcohol induces altered glycans to promote bacteria adhesion. Heavy alcohol drinking is known to increase the risk of bacterial pneumonia. However, the link between alcohol levels and risk of infection remains underexplored. Recently, we found that alcohol induced α2‐6sialo mucin O‐glycans in human tracheobronchial epithelial cells, which mediated the ...

Etude de la phase préfermentaire de la vinification: extraction et formation de certains composés de l'arôme; cas des terpenols, des aldehydes et des alcools en C6 *

open access: yesOENO One, 1981
En vinification en blanc, le pressurage s'accompagne d'un enrichissement des jus en composés de l'arôme. Parmi eux il convient de distinguer ceux qui, comme les terpénols existant déjà dans la baie, sont simplement extraits et ceux qui, comme les ...
