5-Ring Polycyclic Aromatic Hydrocarbons, Uptake, Metabolism, Plant Cell Suspension Cultures, Chenopodiaceae Three 14C-labelled 5-ring PAHs, benzo(a)pyrene, dibenz(a,h)anthracene and perylene were added to various cell suspension cultures of plants belonging to the Chenopodiaceae family. The differently configurated 5-ring systems varied in uptake and metabolism. The uptake of benzo(a)pyrene was...

Anthracene fibers are grown inside a microstructured quartz matrix to form a multicore optical fiber for X-ray detection. A modified fiber growth method for single crystal anthracene from the melt via the Bridgman-Stockbarger technique is presented. The anthracene fiber is characterized by using spectrophotometry, Raman spectroscopy, and X-ray diffraction. These results show the anthracene grow...

Benz[a]anthracene is a ubiquitous environmental contaminant formed during the incomplete combustion of organic material. Some of the metabolites of benz[a]anthracene are known to be toxic and carcinogenic. In this investigation, benz[a]anthracene-induced oxidative damage to lymphocyte DNA was evaluated with the Comet assay (single cell gel electrophoresis). The level of oxidative DNA damage cau...

Abstract Several properties of a series novel disubstituted pentacenes, in which the substituents are donor and acceptor groups, were investigated by using ab initio methods. In particular, role different substitution positions for group was explored. Calculations predict that pentacene derivatives highly soluble oxidatively stable than unsubstituted pentacene. Simulated absorption spectra show...


 1,3-Thiazole is one of the most attractive cores in heterocycles chemistry and drug discovery. Its widespread use diverse medicinal substances makes thiazole a versatile scaffold, which leads to novel generation efficient pharmaceuticals. This study was intended synthesize series N,N-disubstituted aminothiazole derivatives having various fragments at 4th 5th positions ring. The formation...

An efficient one pot condensation of naphthols (1), 2,5-disubstituted indole-3-carboxaldehydes (2), and secondary amines (3) has been achieved using dichloromethane as a solvent, stirring at room temperature. Some of the new [(disubstituted amino)(5-substituted 2-phenyl-1H-indol-3-yl)methyl]naphthalene-ols (4) derivatives were prepared in good yields. The significant features of this method are...

Thiadiazole and their derivatives have been studied extensively because of their wide range of biological activity. They are found to be effective as antibacterial, antimalarial, antiviral, antiinflammatory, anticancer and antianthelminthic agents. Diverse biological activities, such as antibacterial, anti-inflammatory, and antiviral have been associated with 1,3,4Thiadiazole derivatives. The s...
