Synthetic strategies towards the carbenoid reactions of alpha,beta-acetylenic carbonyls

Catalytic reactions of alpha, beta-conjugated carbonyl compounds have been a practical tool towards the synthesis of different useful heterocyclic compounds. Despite the numerous reactions with carbon-carbon double bond conjugated carbonyls, reactions of acetylenic carbonyls are limited. In this study, efficient dioxole synthesis was carried out via acetylenic aldehydes and butadiene formation was preferred over cyclopropene formation via acetylenic esters as different functional groups on these substrates change the product distribution. Both reaction conditions (such as solvent and temperature) and electrophilic structure of metal carbenoids alter the product distribution; acceptor (A), donor-acceptor (DA), and acceptor-acceptor (AA) functionalized diazo compounds yield different product types over different mechanisms.

NMR characterization of penetrants in high permeability polymers

Spectra of xenon-129 sorbed into two high permeability polymers are reported. The polymers are the copolymer of tetrafluoroethylene and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole as well as poly(1-trimethylsilyl-1-propyne). At room temperature, the xenon-129 shifts are smaller than in conventional glassy polymers. The smaller xenon-129 shift indicates the presence of larger sorption sites in high permeability polymers relative to conventional polymers. The temperature dependence of solubility in these polymers is drastically different from the behavior in conventional polymers. There is a rapid exponential increase in solubility in high permeability polymers as temperature decreases corresponding to a large negative enthalpy change on sorption and it is this increase in solubility which leads to a large increase in shift with decreasing temperature. Pulse field gradient (PFG) determinations of the self-diffusion constant are made for xenon, propane, pentane and a decafluoropentane in the copolymer. Rapid diffusion is observed as well as a dependence of the apparent diffusion constant on the time scale of the PFG experiment. The translational mobility of smaller simpler moieties depends less on the time scale or equivalently, the length scale of observation in the PFG NMR experiment. For larger, more complex species, the interconnectedness of high free volume domains plays a role in reducing the apparent diffusion constant as the time of measurement increases.

Novel Thiourea Derivatives Bearing Sulfonamide Moiety as Anticancer Agents Through COX-2 Inhibition

Background: Thiourea derivatives bearing sulfonamide moiety are well known for their anticancer activity. Objective: The anticancer activity of the target compounds was studied, via inhibition of COX-2 enzyme. Method: A series of novel thioureas 5a-n, 8, quinazoline 6, benzo[g] quinazoline 7 and benzo[1,3] dioxole 10, bearing a sulfonamide moiety was synthesized from the starting compound N-(2,6-dimethoxypyrimidin-4-yl)-4isothiocyanatobenzenesulfonamide 2. The target compounds were screened against HepG2, MCF-7, Caco-2, HCT-116, PC-3 cancer cell lines and VERO-B normal cell line. Results: Out of all the tested compounds, compound 5c showed a broad selective cytotoxicity against HepG2, MCF-7, Caco-2 and PC-3 cancer cells. Moreover, a sensitization assay was performed on Caco-2 cells, and compound 5c proved to act as a chemosensitizer for cisplatin on colon cancer (Caco-2) cells. The target compounds were further screened in vitro for their anti COX1/COX2 activity and investigated in vivo as antiinflammatory agents against carrageenan-induced rat paw oedema model. Conclusion: Compound 5g showed the most selective inhibitory activity against COX-2. While, compounds 5a, 6, 5m, 5n, 5g and 5i revealed significant anti-inflammatory effect as presented in carrageenan-induced oedema assay. Molecular docking of the tested compounds disclosed important binding modes which may be responsible for their anticancer activity via inhibition of the COX-2 enzyme.

Effect of annealing temperature on antireflection property and water contact angle of fluorine-based hydrophobic films by a sol-gel technique

Crack-free and smooth surfaces of poly[4,5-difluoro 2,2-bis-(trifluoroinethyl)-1,3 dioxole]-co-tetrafluoroethylene (TFE-co-TFD) films have been deposited by sol-gel technique on polished AISI 440C steel and quartz substrates. The deposited films have been subjected to annealing at different temperatures ranging from 100 to 500 degreesC for 1 h in argon atmosphere. The as-deposited and annealed films (below 300 degreesC) on quartz have shown antireflection behaviour in the UV region. Surface properties of the films have been examined by employing scanning electron microscopy, energy dispersive X-ray analyser, for morphology and elemental composition. Adhesion strength failure was measured by scratch resistance test technique indicated good adhesion of the films on the substrate. It was found that as the annealing temperature increased from 100 to 400 degreesC, nanostructured sphere like balls were formed which in turn has shown increase in the contact angle for water from 122degrees to 247degrees. No change in the water contact angle (122degrees) has been observed when the films deposited at room temperature were heated in air from 30 to 80 degreesC indicating thermal stability of the coating.

Novel furfurylidene N-acylhydrazones derived from natural safrole: discovery of LASSBio-1215, a new potent antiplatelet prototype

We describe herein the discovery of (E)-N-methyl-N’-((5-nitrofuran-2-yl) methylene) benzo[d][1,3]dioxole-5-carbohydrazide (9e), named LASSBio-1215, as a novel antiplatelet agent belonging to the N-methyl-N-acylhydrazone class, which exert their antiaggregating actions on human and rabbit platelets induced by different agonists, through cyclooxygenase-1 (COX-1) or thromboxane synthase inhibition. This compound was elected after screening of a series of functionalized furyl N-acylhydrazone derivatives, synthesized from natural safrole 10. In vitro assays showed that compound 9e presents platelet-aggregating activity in rabbit platelet-rich plasma (PRP) induced by arachidonic acid (IC50 = 0.7 mu M) and collagen (IC50 = 4.5 mu M). Moreover, LASSBio-1215 also inhibited almost completely the second wave of adenosine diphosphate-induced platelet aggregation in human PRP, and this effect was correlated with their ability to block the production of pro-aggregating autacoid thromboxane A(2).
