Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 5959-52-4, Name is 3-Amino-2-naphthoic acid, molecular formula is C11H9NO2, belongs to naphthyridines compound. In a document, author is Yue, Xiao-li, introduce the new discover, HPLC of Formula: C11H9NO2.
A novel Schiff-base fluorescent probe based on 1,8-naphthyridine and naphthalimide for Al3+
A novel Schiff-base, 7-acetamino-4-methyl-1,8-naphthyridine-2-carbaldehyde-(1′,8′-naphthalenedicarbonyl) hydrazone (HL) was designed, synthesized and evaluated as a fluorescent probe. The fluorescence properties of this probe towards various metal ions were investigated by UV-vis and fluorescence spectra in methanol. Test results indicated that the probe had high selectivity towards Al3+ over other commonly coexisting metal ions. Upon addition of Al3+, the fluorescence intensity at 414 nm increased significantly due to the inhibition of the PET process. The binding constant (Ma) of Al3+ binding to HL was calculated to be 5.64 x 10(4) M-1 from a Benesi-Hildebrand plot, and the detection limit(LOD) of HL for sensing Al3+ was calculated to be 0.13 mu M. The binding stoichiometry between HL and Al3+ was determined as 1:1 by the Job’s plot. Furthermore, the probe was chemically reversible for Al3+ in methanol by the addition of Na(2)EDTA solution.
