The present study demonstrates the benefits of combinatorial antioxidant therapy in the treatment of ischemic stroke. Male Sprague-Dawley rats were anaesthetised and the middle cerebral artery (MCA) was occluded for 30 minutes followed by 5.5 hours of reperfusion. Pretreatment with resveratrol 30 mi...

Stability-indicative detn. of bambuterol hydrochloride (BH) in the presence of its degrdn. product (terbutaline), which is also the metabolite, is investigated. The degrdn. product was isolated, via acid-degrdn., characterized and elucidated. Selective quantification of BH, singly in bulk form, phar...

Edaravone, an electron spin trapper with radical scavenging activity, has been shown to be effective in reducing infarct volume in humans following ischemic stroke. However, concerns of edaravone-induced renal toxicity have limited its clinical adoption. Previous work has demonstrated that edaravone...

A novel series of functionalized thiophenes incorporating coumarin, pyrene and naphthalene pendants were synthesized by Steglich esterification in the presence of DCC/DMAP (dicyclohexylcarbodiimide/N,N-dimethylaminopyridine) and the synthesized monomers were electrochemically deposited onto glassy c...

Cyclic aryl ethers, thioethers or amines, and methods for synthesis are
disclosed. These cyclic aryl compounds are synthesized by combining a first
dinucleophile with a substituted benzene metallized electron-withdrawing
complex,
having halo or nitro substituent groups, to form a li...

Cyclic aryl ethers, thioethers or amines, and methods for synthesis are disclosed. These cyclic aryl compounds are synthesized by combining a first dinucleophile with a substituted benzene metallized electron-withdrawing complex, having halo or nitro substituent groups, to form a linear bimetallized...

This thesis describes the synthetic strategies for the incorporation of a number of metal species into a series of polynorbornenes, as well as their characterization and thermal analysis. This was accomplished through the synthesis of new monometallic norbornene compounds containing chromium and iro...

Multifunctional macromolecules continue to attract attention. Here, three generations of a new family of bifunctional organoiron dendrimers are reported, which are synthesized from a redox-active organoiron complex, η6-dichlorobenzene-η5-cyclopentadienyl-iron(II). The facile chemistry of the compl...

In this investigation, the hydration characteristics and microstructure of calcium aluminate cement (CAC) contg. different proportions of high slag (HSC) and sulfate resisting cements (SRC) were studied. The blends were made from CAC with the partial replacement of HSC or SRC of 5, 10, 15, 20 and 25...

Polarographic half-wave potentials for two reduction steps of 49 cyclopentadienyliron complexes of substituted arenes or heterocycles in dimethylformamide were determined. A fast cyclic voltammetry (10–40 V/s) was used to study the electron transfer kinetics of some of these complexes. After corre...

Electrochemical reduction studies of a series of η6-polycyclic and η6-heterocyclie arene-η5-cyclopentadienyliron cations were carried out in different solvents and at different temperatures. The complexes were reduced in two one-electron steps. Stability of the first reduction product was much hi...

Radical polymerization of organoiron (alkynyl methacrylate)s afforded a series of organoiron poly(alkynyl methacrylate)s with the ability to coordinate dicobalt hexacarbonyl. The polymers were post-modified with dicobalt hexacarbonyl moieties through reaction with dicobaltoctacarbonyl. Gel permeatio...
