High-throughput untargeted screening of veterinary drug residues and metabolites in tilapia using high resolution orbitrap mass spectrometry.

Wei Jia et al.

Analytica chimica acta, 957, 29-39 (2017-01-22)

An analytical method was developed and validated for simultaneous analysis of one hundred and thirty-seven veterinary drug residues and metabolites from sixteen different classes in tilapia utilizing an improved fully non-targeted way of data acquisition with fragmentation. The automated on-line

Fluorescence spectra of 3-aminocoumarin and its acid-base behaviour in the excited singlet state.

Rao RVS, et al.

Journal of Photochemistry, 34(1), 55-61 (1986)

Effect of Pharmacological Inhibition of the Catalytic Activity of Phosphatases of Regenerating Liver in Early T Cell Receptor Signaling Dynamics and IL-2 Production.

Oscar Aguilar-Sopeña et al.

International journal of molecular sciences, 21(7) (2020-04-09)

We have previously shown the delivery of phosphatase of regenerating liver-1 (PRL-1) to the immunological synapse (IS) and proposed a regulatory role of the catalytic activity of PRLs (PRL-1, PRL-2 and PRL-3) in antigen-induced IL-2 production. Nonetheless, the expression in

Synthesis of biologically potent new 3-(heteroaryl) aminocoumarin derivatives via Buchwald-Hartwig C-N coupling.

Povarov reactions involving 3-aminocoumarins: synthesis of 1,2,3,4-tetrahydropyrido[2,3-c]coumarins and pyrido[2,3-c]coumarins.

Amit A Kudale et al.

The Journal of organic chemistry, 73(21), 8437-8447 (2008-09-30)

Condensation of 3-aminocoumarin (5) with 4-nitrobenzaldehyde (8) afforded a 2-azadiene (9), which reacted with various electron-rich alkenes (10 examples) in the presence of Yb(OTf)3 to afford 1,2,3,4-tetrahydropyrido[2,3-c]coumarins. Yields were generally good, but the diastereomeric ratios were highly variable. The products

[Antiradical activity of 3-substituted coumarins and their effect on iron-dependent chemiluminescence].

Iu A Vladimirov et al.

Biulleten' eksperimental'noi biologii i meditsiny, 112(10), 358-360 (1991-10-01)

The antioxidant capacity of 3-aminocoumarin, 3-oxycoumarin, 3-acetylaminocoumarin, and 3-coumarin carbonic acid has been investigated with chemiluminescence measurement and by the accumulation of TBA-active products. All coumarins were found to be antioxidants, with 3-oxy-, 3-amino- and 3-acetylamino coumarins being capable of

Hydrolysis-free synthesis of 3-aminocoumarins.

Kudale AA, et al.

Tetrahedron Letters, 48(29), 5077-5080 (2007)

Development of novel adenosine receptor ligands based on the 3-amidocoumarin scaffold.

Maria J Matos et al.

Bioorganic chemistry, 61, 1-6 (2015-06-05)

With the aim of finding new adenosine receptor (AR) ligands presenting the 3-amidocoumarin scaffold, a study focusing on the discovery of new chemical entities was carried out. The synthesized compounds 1-8 were evaluated in radioligand binding (A1, A2A and A3)

Antimicrobial and antioxidant activities of new metal complexes derived from 3-aminocoumarin.

Abdul Amir H Kadhum et al.

Molecules (Basel, Switzerland), 16(8), 6969-6984 (2011-08-17)

3-Aminocoumarin (L) has been synthesized and used as a ligand for the formation of Cr(III), Ni(II), and Cu(II) complexes. The chemical structures were characterized using different spectroscopic methods. The elemental analyses revealed that the complexes where M=Ni(II) and Cu(II) have
