A highly selective and sensitive rhodamine-derived fluorescent probe for detection of Cu2?+
Lv, Linlin,Diao, Quanping
, p. 221 - 226 (2017)
A novel water-soluble and reversible fluorescent probe was designed and synthesized based on a rhodamine B derivative. It was used for detection of Cu2?+ in drinking water and in living cells with high sensitivity and excellent selectivity. The tested concentration range and the limit of detection (LOD) of the probe were 0–15.00?μmol?L??1 and 0.085?μmol?L??1, respectively. In addition, the mode of binding and mechanism of interaction between the probe and Cu2?+ were analyzed by density functional theory (DFT) calculations.

A material was fabricated based on the Schiff base reaction to achieve covalent attachment of NH2-MIL-53(Al) and the 3-formylsalicylic acid ligand (3-FSA) for fluorimetric detection of Zn2+ ions based on inhibition and destruction of CN isomerization and ESIPT. The low limit of detection and limit of quantification were calculated at optimum conditions. The selectivity of the 3-FSA sensor was achieved against some interfering ions. The new sensor was applied for the determination of Zn2+ ions in cosmetic cream products and the obtained results were validated through comparison with ICP-OES. The data indicated that the 3-FSA sensor provided a sensitive, selective, fast, direct and efficient determination of Zn2+ ions with good reproducibility and reversibility.

A copper-mediated Duff reaction for ortho-selective formylation of phenols has been developed. In the presence of copper species, significant improvements of yield and ortho-selectivity of the Duff formylation were achieved, which provides an easy access to salicylaldehydes from phenols.

Photoactive 2-(2′-hydroxyphenyl)benzoxazole-1,4-dihydropyridine (HBO-DHP) dyads were obtained by a multicomponent one-pot Hantzsch synthesis using a fluorescent aldehyde, a 1,3-dicarbonylic compound and ammonium acetate. The key step in this synthetic methodology was the synthesis of the formyl benzoxazole derivative through a Duff-modified functionalization protocol. UV-Vis absorption and fluorescence emission spectroscopies were also applied to better understand the photophysics of these compounds. The three novel fluorescent compounds were obtained in moderate yields as stable solids with absorption in the UV region and emission in the blue-green region. Preliminary results indicate that after excitation both HBO and DHP fluorophores behave independently in the HBO-DHP structure. the Partner Organisations 2014.
New fluorescent sensor for Cu2+ and S2- in 100% aqueous solution based on displacement approach
Fu, Yan,Feng, Qing-Chuan,Jiang, Xiu-Juan,Xu, Hong,Li, Min,Zang, Shuang-Quan
, p. 5815 - 5822 (2014/04/03)
An On-Off-On type fluorescent sensor (HL) has been developed, which exhibited high selectivity and sensitivity for Cu2+ over other common ions in 100% aqueous solution. Once HL combined with Cu2+, blue fluorescence was almost complet
Studies on benzofuran-7-carboxamides as poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors

experimental part, p. 1147 - 1153 (2012/07/14)
Benzofuran-7-carboxamide was identified as a novel scaffold of poly(ADP-ribose) polymerase-1 (PARP-1) inhibitor. A series of compounds with various 2-substituents including (tertiary amino)methyl moieties substituted with aryl ring and aryl groups containing tertiary amines, were synthesized and biologically evaluated to elucidate the structure-activity relationships and optimize the potency. 2-[4-(Pyrrolidin-1-ylmethyl)phenyl]-benzofuran-7- carboxamide (42) was the most potent as an IC50 value of 40 nM among those.
Kinetic characterization of spiropyrans in aqueous media
Stafforst, Thorsten,Hilvert, Donald
scheme or table, p. 287 - 288 (2009/05/06)
Detailed kinetic investigations of the most common photoswitchable spiropyran, 6-nitro-BIPS, reveal that hydrolytic decomposition of its merocyanine isomer limits its utility in aqueous buffer; however, simple replacement of the 6-nitro substituent with a
