First synthesis of novel aminophenyl pyridinium-5-(hydroxybenzoyl)-hydrazonomethyl-2-oxothiazol-3-ide derivatives and evaluation of their anticancer activities
Min, Dongguk,Han, Moon Hi,Lee, Seulki,Jung, Mankil
, p. 843 - 847 (2015)
The first total synthesis for large-scale production and anticancer activity of novel aminophenylpyridinium-5-(hydroxybenzoyl)hydrazonomethyl-2-oxothiazol-3-ide (PBHT) (1) and its derivatives are reported. The chemical structure of PBHT was unambiguously
Push-pull [2]pseudorotaxanes. Electronic control of threading by switching on/off an intramolecular charge transfer
Vella, Sarah J.,Tiburcio, Jorge,Gauld, James W.,Loeb, Stephen J.
, p. 3421 - 3424 (2006)
Addition of acid and base allows switching between two different structures in a push-pull bis(pyridinium)ethane axle, controlling its ability to form [2]pseudorotaxanes with a dibenzo-24-crown-8 ether wheel.
Fluorescent molecular rotors as sensors for the detection of thymidine phosphorylase
Petaccia, Manuela,Giansanti, Luisa,Wilson, James N.,Lee, Heajin,Battista, Sara,Mancini, Giovanna
, (2021)
Three new fluorescent molecular rotors were synthesized with the aim of using them as sensors to dose thymidine phosphorylase, one of the target enzymes of 5-fluorouracil, a potent chemotherapic drug largely used in the treatment of many solid tumors, tha
Some reactions of pyridinium salts derived from trichloromethylarenes with N- and C-nucleophiles
Belen'kii,Poddubnyi,Luiksaar,Krayushkin
, p. 1172 - 1176 (2000)
The reaction of N-(4-pyridyl)pyridinium and 4-chloropyridinium salts obtained from 1-trichloromethyl-2,4,6-trimethylbenzene and pyridine with N-nucleophiles such as piperidine and morpholine and with C-nucleophiles such as N,N-dimethylaniline and indole proceeds through hetarylation and gives the corresponding 4-substituted pyridines. N-(α,α-Dichlorobenzyl)pyridinium and N,N'-(α-chlorobenzylidene)bispyridinium salts obtained from trichloromethylbenzene do not undergo hetarylation.
Nickel-Catalyzed Amination of Aryl Chlorides with Amides
Li, Jinpeng,Huang, Changyu,Wen, Daheng,Zheng, Qingshu,Tu, Bo,Tu, Tao
, p. 687 - 691 (2021/01/09)
A nickel-catalyzed amination of aryl chlorides with diverse amides via C-N bond cleavage has been realized under mild conditions. A broad substrate scope with excellent functional group tolerance at a low catalyst loading makes the protocol powerful for synthesizing various aromatic amines. The aryl chlorides could selectively couple to the amino fragments rather than the carbonyl moieties of amides. Our protocol complements the conventional amination of aryl chlorides and expands the usage of inactive amides.
Fluorescent substrates for neurotransmitter transporters

, (2011/06/19)
The invention is based on the finding that IDT307 and analogs thereof are fluorescent substrates transported by several neurotransmitter transporters. Provided are methods for the analysis of neurotransmitter transport and binding using IDT307 and its ana
Highly stable 7-N,N-dibutylamino-2-azaphenanthrene and 8-N,N-dibutylamino- 2-azachrysene as a new class of second order NLO-active chromophores
Calabrese, Valentina,Quici, Silvio,Rossi, Ester,Cariati, Elena,Dragonetti, Claudia,Roberto, Dominique,Tordin, Elisa,De Angelis, Filippo,Fantacci, Simona
supporting information; experimental part, p. 8374 - 8376 (2011/02/21)
7-N,N-Dibutylamino-2-azaphenanthrene (L3), 8-N,N-dibutylamino-2- azachrysene (L4) and related Ir(i) complexes or alkylated salts show high second-order NLO responses, as determined by the EFISH technique and DFT calculations. L4
Radical Cation Probes for Photoinduced Intramolecular Electron Transfer in Metal-Organic Complexes
Wang, Yingsheng,Schanze, Kirk S.
, p. 5408 - 5419 (2007/10/03)
Two transition metal complexes of the type fac-(bpy)Re(I)(CO)3(DA)(1+) (where bpy = 2,2'-bipyridine and DA is a pyridine ligand that is substituted with a 1,2-diamine electron donor) have been prepared.The 1,2-diamine serves as a "reactive donor ligand" o
STRUCTURE-COLOUR REALATIONSHIP OF SOME NEW N-ARYLPYRIDINIUM HEMICYANINE DYES
Hutchings, Michael G.
, p. 2061 - 2068 (2007/10/02)
N-aryl derivatives of 4-(p-dimethylamino)pyridine are novel examples of donor-acceptor dyes.Para-substituents in the N-aryl group influence the spectra, such that the more electron-withdrawing lead to more bathochromic shifts.However, a 2-nitro-substituen
