Symmetric and asymmetric chalcogenides of organic nature are a class organometallic compounds that widely used as intermediates in number reactions, ligands the chemistry coordination compounds, they have wide range biological activity. Diaryl tellurides, which important for formation new carbon-carbon bonds, special area organotelluric compounds. The synthesis representatives this tellurium-co...

The reaction of 4,5-dichloro-1,2,3-dithiazolium chloride with 2-(phenylsulfonyl)acetonitrile (1 equiv) in the presence pyridine (2 gave S-(3-chloro-5-cyanoisothiazol-4-yl)benzenesulfonothioate and (Z)-2-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-2-(phenylsulfonyl)acetonitrile 19% 23% yield, respectively. compounds were fully characterized mechanistic rationale is proposed for formation benzensulfo...

This study was designed to compare the effects of several neuroactive steroids with varying patterns of modulation of g-aminobutyric acid (GABA)A and NMDA receptors on operant self-administration of ethanol or water. Once stable responding for 10% (w/v) ethanol was achieved, separate test sessions were conducted in which male Wistar rats were allowed to self-administer ethanol or water followin...

Chemotherapy represents the most applied approach to cancer treatment. Owing frequent onset of chemoresistance and tumor relapses, there is an urgent need discover novel more effective anticancer drugs. In search for therapeutic alternatives treat disease, a series hybrid pyrazolo[3,4-d]pyrimidin-4(5H)-ones tethered with hydrazide-hydrazones, 5a–h, was synthesized from condensation reaction pyr...

to determine chromosomal localization and relationship between field and laboratory indicators of drought tolerance, an experiment was conducted in 2003-2004 cropping season at sararood agricultural research station, kermanshah, iran. seven genotypes of wheat-barley disomic addition lines provided by international center for agricultural research in dryland areas (icarda), their donor and recip...

In the title compound, C(4)H(3)ClO(3), mol-ecules are linked via O-H⋯O hydrogen bonds into an infinite chain with graph-set motif C(6) along the c axis.

The title mol-ecule, C(13)H(8)N(4), is is essentially planar [r.m.s. deviation for all non-H atoms = 0.025 (3) Å]. In the crystal, mol-ecules are connected through one weak bifurcated N-H⋯(N,N) hydrogen bond and three π-π stacking inter-actions between pyridine and imidazole rings [centroid-centroid distance = 3.631 (8) Å] and between pyridine and benzene rings [centroid-centroid distances = 3....
