Tropane alkaloids such as scopolamine (C17H21NO4), atropine (C17H23NO3) and hyoscyamine (C17H23NO3) are the most important plant secondary metabolites in the pharmaceutical industry due to anticholinergic activity, competition with muscarinic receptors and also treating different human diseases. Scopolamine, hyoscyamine and atropine are the most important tropane alkaloids used as anticoagulant...

In this letter, we report a novel synthesis of ethyl quinoline-3-carboxylates from reactions between a series of indoles and halodiazoacetates. The formation of the quinoline structure is probably the result of a cyclopropanation at the 2- and 3-positions of the indole followed by ring-opening of the cyclopropane and elimination of H-X.

The study of the Vilsmeier-Haack reagent on 4-hydroxyquinaldines resulted in a new versatile intermediate 4-chloro-3-formyl-2-(2-hydroxy-ethene-1-yl)quinolines, which on further treatment with hydrazine hydrate yielded the desired diazepino quinoline derivatives. All the synthesized diazepino quinoline derivatives are screened for their antibacterial and antifungal activities. Cytogenetic analy...

In the title compound, C(19)H(16)ClNO(2), the quinoline ring system is planar (r.m.s. deviation = 0.008 Å). The phenyl group and the -CO(2) fragment of the ester unit form dihedral angles of 60.0 (1) and 60.5 (1)°, respectively, with the quinoline ring system.

In the title compound, C(11)H(8)ClNO(2), the quinoline fused-ring system is almost planar (r.m.s. deviation = 0.020 Å). The formyl group is slightly bent out of the quinoline plane [deviation of the O atom = 0.371 (2) Å].

Novel quinoline derivatives was designed as anticancer iron chelators. Structurally they combine active moieties of known quinoline and thiosemicarbazone bioeffectors. For the synthetic part of study we applied microvawe assisted techniques MAOS. Resulted compounds exhibited interesting anticancer activities against HCT116 cancer cells.

According to the Chinese Pharmacopoeia 2015, only processed Aconitum tubers can be clinically applied, and the effect of processing is unclear. This research aimed to explore the effect of processing on cardiac efficacy of alkaloids in Aconitum tubers. First, the chemical ingredients in unprocessed and processed Aconitum tubers were identified and compared by using high performance liquid chrom...

A bacterial culture was isolated from oil-contaminated soil based on its ability to metabolize the quinoline as the sole source of nitrogen. In this research Bacillus licheniformis strain was identified based on the result of 16S rRNA analysis. Optimized conditions were obtained with full factorial experimental design method using design expert software at temperature: 32<...

Ligands derived from 8-quinoline, 6-quinoline, 1 -isoquinoline, and 5-isoquinoline were synthesized. These compounds have been used as ligands for complexation of transition metals, such as copper(II) and nickel(II). According to the spectrosocopic data, copper(II) cation forms (I: 1) and (I:2) complexes with 2-(8-quinoly1)-l,l,3,3- tetramethylguanidine and 2- (I '-isoquinoly1)- 1,1,3,3-tetr...
