We provide two simple low-cost and low-tech procedures to measure with good precision and accuracy the binding and internalization into human erythrocytes of chloroquine and other aminoquinolines. The methods are based on the high fluorescence of the quinoline ring and are complementary. Method A evaluates residual drugs in the supernatants of treated erythrocytes, whereas method B quantifies t...

In the centrosymmetric dinuclear title complex, [Mn(2)(C(16)H(10)NO(2))(4)(C(12)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, the Mn(II) cation is in a distorted octa-hedral coordination geometry defined by two N atoms from a 1,10-phenanthroline ligand, one water O atom and three O atoms from three 2-phenyl-quinoline-4-carboxyl-ate anions. A pair of 2-phenyl-quinoline-4-carboxyl-ate anions bridge two Mn cati...

The title hydrate, C(27)H(23)NO(2)·H(2)O, features an almost planar quinoline residue (r.m.s. deviation = 0.015 Å) with the benzene [dihedral angle = 63.80 (7) °] and chalcone [C-C-C-O torsion angle = -103.38 (18)°] substituents twisted significantly out of its plane. The configuration about the C=C bond [1.340 (2) Å] is E. In the crystal, mol-ecules related by the 2(1) symmetry operation are l...

A novel monosubstituted organoimido hexamolybdate containing 6-nitroquinoline moiety has been successfully synthesized. This organically-functionalized polyoxometalate exhibits proton-induced switchable fluorescence property in aqueous acetonitrile solution at room temperature. Experimental and theoretical investigations of this reversible "on" and "off" switching mechanism have been carried ou...

A natural and efficient method has been developed for the synthesis of quinoline derivatives in good-to-high yields, from various aryl aldehydes, amines and phenyl acethylene, using marine sponge/I2 as a green catalyst

Eggshell was found to be a versatile heterogeneous catalyst for the synthesis of pyrano[3,2-c]quinoline derivatives in good yields. This protocol has the advantages of environmental friendliness, short reaction time, low cost and convenient operation.

Recently, magnetic iron oxide nanoparticles functionalized with various organic groups increasing attention in the synthesis of compounds. In this study, ionic liquid nano-magnetic pyridinium-tribromide (MNPs@SiO2-Pr-AP-tribromide) as a new nano-catalyst was synthesized. The structure catalyst identified by FT-IR, TGA, XRD, FE-SEM, EDX, EDS, TEM and VSM analysis. efficient for quinoline derivat...

As part of improving the quality wash oil, reduction three kinds nitrogen-containing compounds (NCs), including quinoline (QU), iso-quinoline (IQU), and indole (IN), found in oil was examined by liquid–liquid equilibrium extraction. The an aqueous solution formamide were used as raw material solvent, respectively. Increasing volume fraction water solvent initial state (yw,0) resulted a decrease...

The human body is full of various ions, which play an important role in the normal physiological activities. For example, Zinc ion (Zn2+) plays a vital role in protein organism and in many biochemical processes, such as inducing apotosis, enzyme regulation, and gene expression. Also, Ferrous ion (Fe2+) is vital in the oxygen transporting. But there are some ions harmful to human body. When expo...

The title compound, C(10)H(7)NO, crystallizes with two almost planar mol-ecules (A and B) in the asymmetric unit (r.m.s. deviations = 0.018 and 0.020 Å). In the crystal, the A mol-ecules are linked by weak C-H⋯O inter-actions, thereby generating C(9) [001] chains. The B mol-ecules do not exhibit any directional bonding inter-actions.
