In the title compound, C(4)HBr(3)S, there are two essentially planar mol-ecules in the asymmetric unit. In the crystal structure, bifurcated C-H⋯Br hydrogen bonds link the mol-ecules into chains. Weak Br⋯Br inter-actions [Br⋯Br = 3.634 (4)-3.691 (4) Å] then lead to undulating sheets in the bc plane.

A quantum chemical investigation was carried out to study the properties of intermolecular F•••F, Br•••Br and Br•••O interactions in crystalline 1-bromo-2,3,5,6-tetrafluoro-nitrobenzene (BFNB). This system was selected to mimic the halogen-halogen as well as halogen bonding interactions found within crystal structures as well as within biological systems. We found that fluorine atoms have weak ...

Brassinosteroid (BR)-induced antioxidant defence has been shown to enhance stress tolerance. In this study, the role of the maize 65 kDa microtubule-associated protein (MAP65), ZmMAP65-1a, in BR-induced antioxidant defence was investigated. Treatment with BR increased the expression of ZmMAP65-1a in maize (Zea mays) leaves and mesophyll protoplasts. Transient expression and RNA interference sil...

background: brown rice (br) is unpolished rice with various beneficial compounds such as vitamins, magnesium and other minerals, dietary fiber, essential fatty acids, γ‑oryzanol and γ‑aminobutyric acid. in the present study, we compared the effects of white rice (wr) and br on inflammatory marker high‑sensitivity c‑reactive protein (hs‑crp) and cardiovascular risk factors among non‑menopausal o...

The photodissociation dynamics of 2-bromopentane at ∼234 nm has been investigated by utilizing ion-velocity map imaging technique. The mapped images of Br(P3/2) (denoted as Br) and Br(P1/2) (denoted as Br∗) fragments were analyzed by means of the speed and angular distributions, respectively. The speed distributions can be fitted with two Gaussian components which are correlated to the two inde...

Heterobimetallic complexes in which half-sandwich complexes of ruthenium(), rhodium() and iridium() are connected by three bromo-bridges to Re(CO)3 have been prepared from metathesis reactions of [RuBr(μ-Br)(arene)]2 (arene = C6H6, C6H3Et3-1,3,5 or p-cymene) or [MBr(μ-Br)Cp*]2 (M = Rh or Ir) with [Re(μ-Br)(CO)3(C4H8O)]2. The crystal structures of [(arene)Ru(μ-Br)3Re(CO)3] (arene = C6H6 ...

Cyclohexanol is an organic chemical intermediate product widely used in chemical<br /> industry and commonly produced by cyclohexene hydration. Because of the low mutual<br solubility water, reaction limited equilibrium,<br which has disadvantage conversion cyclohexene. In this paper, hydration catalysed A-36 cation exchange resin catalyst was analysed Aspen Plus V8.6 simulation sof...

Serological analysis of recombinant cDNA expression libraries (SEREX) has led to the identification of several categories of new tumor antigens. We analyzed a testicular cDNA expression library with serum obtained from a breast cancer patient and isolated 13 genes designated NW-BR-1 through NW-BR-13. Of these, 3 showed tumorrestricted expression (NW-BR-1, -2 and -3), the others being expressed ...

Brassinosteroids (BRs) are steroidal hormones that play pivotal roles during plant development. In addition to the characterization of BR deficient mutants, specific BR biosynthesis inhibitors played an essential role in the elucidation of BR function in plants. However, high costs and limited availability of common BR biosynthetic inhibitors constrain their key advantage as a species-independe...

Photolabile compounds which rapidly release cAMP or cGMP after photolysis are widely used for in situ studies of signaling pathways inside cells. We synthesized two novel caged compounds, 4,5-dimethoxy-2-nitrobenzyl 8-Br-cAMP (caged 8-Br-cAMP) and 4,5-dimethoxy-2-nitrobenzyl 8-Br-cGMP caged 8-BR-cGMP), which respectively release the hydrolysis-resistant analogues 8-Br-cAMP and 8-Br-cGMP. Their ...
