Iodine deficiency impacts on the development of thyroid disease. Vegetables and fruits usually have a low iodine content; hence, it makes sense to increase their content. Potato is consumed daily by millions consumers would, therefore, be good target for biofortification with programs. The aim this study was determine effects via application soil solutions two iodoquinolines [8-hydroxy-7-iodo-5...
By mean of heterophase polymerization on the silica gel surface has been made in situ immobilization poly [8-methacroyloxy-quinoline], received new organic-mineral composite material. I...
A series of 1-(4-methylquinolin-2-yl)-4,6-diaryl-1H-pyrazolo[3,4-b]pyridin-3-amine derivatives was synthesized by the reaction of 3-cinnamoyl-4-hydroxy-6-methyl-2H-pyran-2-ones with 2-chloro-4,6-diphenylnicotinonitrile analogues in the presence of 2-hydrazino-4-methyl quinoline and ethanol. The newly synthesized compounds were characterized by IR, 1H NMR and mass spectral data. The synthetic se...
Quinoline and naphthalene-based fluororeceptors 1 and 2 have been designed and synthesized for detection of hydroxy carboxylic acids in less polar solvents. The receptor 1 shows monomer emission quenching followed by excimer emission upon hydrogen bond-mediated complexation of carboxylic acids. The excimer emission distinguishes aromatic dicarboxylic acids from aliphatic dicarboxylic acids and ...
Scoliosis seen in the chicken after pinealectomy resembles adolescent idiopathic scoliosis in man. It has been suggested that in both species, deficiency of the pineal hormone, melatonin, is responsible for this phenomenon. In nine patients with adolescent idiopathic scoliosis and in ten age- and gender-matched controls, the circadian levels of serum melatonin and the excretion of urinary 6-hyd...
Ž . Ž .

Silicon containing pyridine and quinoline sulfides have been prepared using phase transfer catalytic system thiol/alkyl halide / solid KOH/18-crown-6 / toluene. The target S-ethers were isolated in yields up to 81%. The cytotoxicity of the synthesized compounds was studied. Among pyridine sulfides S-[3-(1-methyl- 1-silacyclohexyl)propyl] derivatives 5e and 6e exhibit the highest cytotoxicity. A...
Occupied and unoccupied densities of states of p-conjugated molecules measured via ultraviolet photoemission spectroscopy and inverse photoemission spectroscopy, respectively, are compared with corresponding densities of states Ž . calculated using the semi-empirical Hartree–Fock intermediate neglect of differential overlap INDO method. Excellent Ž . agreement is obtained for both occupied and ...
As a disease-modifying approach for Alzheimer's disease (AD), clioquinol (CQ) targets beta-amyloid (Abeta) reactions with synaptic Zn and Cu yet promotes metal uptake. Here we characterize the second-generation 8-hydroxy quinoline analog PBT2, which also targets metal-induced aggregation of Abeta, but is more effective as a Zn/Cu ionophore and has greater blood-brain barrier permeability. Given...
The title 1,2,4-triazole compound, C(13)H(11)N(5)OS·C(3)H(7)NO, crystallizes as a 1:1 dimethyl-formamide (DMF) solvate. The main mol-ecule exists in a trans configuration with respect to the acyclic C=N bond. An intra-molecular C-H⋯S hydrogen bond generates an S(6) ring motif. In the synthesis, a proton is transferred from the O atom of a hydr-oxy group to the quinoline group N atom. The essent...
