Advanced Synthesis &Catalysis, Volume 367, Issue 7, April 1, 2025.Abstract Catalytic formal aldol condensation reactions between β‐ketophosphonates and arylaldehydes, in which the C−C double bond formation occurs at the γ‐position of the β‐ketophosphonate, are reported. The reactions were performed in the presence of a catalyst system composed of p‐anisidine and trifluoroacetic acid under mild conditions. Mechanistic

Repeated batch for dye degradation in an airlift bioreactor by laccase entrapped in copper alginate [PDF]
, 2017 A repeated batch of synthetic dye decolorization was efficiently demonstrated in a 5 L airlift bioreactor. A laccase from Ganoderma sp. KU-Alk4, degrading commercial aromatic dyes was selected. The crude enzyme extract expressed laccase activity, and was

Mediators of Inflammation, 2016 Extracellular adenosine 5′-triphosphate (ATP) activates the P2X7 receptor channel to induce the rapid release of the proinflammatory cytokine, interleukin- (IL-) 1β, from macrophages. Microtubule rearrangements are thought to be involved in this process.

Isatin: Role in stress and anxiety
Stress, 2005 (Indoledione 2,3) isatin is an endogenous indole found both in mammalian brain and peripheral tissues. Isatin concentration in blood can exceed 1 microM and tissue concentrations vary from < 0.1 to 10 microM. Its level in the brain and periphery is increased by stress. Isatin has a wide spectrum of behavioural and metabolic effects. It is anxiogenic at

Cooperative Vinylogous Enamine and Metal Catalysis
ChemCatChem, Volume 17, Issue 7, April 4, 2025.This review describes transformations combining vinylogous enamine catalysis with transition metal or Lewis acid catalysis that have emerged since the seminal report of dienamine catalysis in 2006. These transformations span numerous reaction classes, including alkylation, allylation, propargylation, oxyamination, dimerization, as well as cascade ...
