O peróxido de benzoíla, produto de interação do peróxido de sódio com cloreto de benzoíla, é um poderoso agente antibacteriano de amplo espectro com ação queratolítica, comedolítica, descamativa, antipruriginosa e desengordurante, além de também ser um potente agente oxidante, que reage com materiais orgânicos rompendo as membranas celulares de inúmeros agentes patogênicos. Em virtude de suas características, o peróxido de benzoíla é utilizado como produto de eleição como adjuvante no tratamento de sarnas (dermodicidoses), desqueratinizações, complexo seborréico, piodermites, foliculites super

Abstract:
Content: Chamois leathers are basically oil tanned leathers, usually requires 10 to 15 days to process from raw skins. In chamois making, air oxidation plays a major role, free radicals initiate the oxidation process in oil, which oxidizes the double bond of the fatty acid and then the oxidized oil interacts with collagen to stabilize the skin by coating the fibers (Fig 1). In the present study an attempt has been made to reduce the time for chamois leather processing. A common oxidizing agent (Benzoyl peroxide (BPO) was utilized to enhance the oxidation of oil and reduce the time duration. It

Three PTPs, PTP-1B, Tc-PTPa, and PTP-H1, and three DSPs, Cdc-14, VHR, and IphP, were challenged in vitro with alpha-naphthyl phosphate and beta-naphthyl phosphate. Both the DSPs and PTPs readily hydrolyzed beta-naphthyl phosphate. As expected, the DSPs also hydrolyzed alpha-naphthyl phosphate at rates

Abstract:
Precision-cut rat liver slices were incubated with various concentrations of benzyl isothiocyanate (BITC) (0-25 μM) for 24 hours. BITC decreased the dealkylation of ethoxy-(EROD) and methoxyresomfin (MROD) but increased CYP1A1/2 apoprotein levels; in vitro studies confirmed that it is mechanism-based inhibitor. BITC decreased both dealkylation of pentoxyresorufin (PROD) and CYP2B1 apoprotein levels but there was no effect on 7-benzyloxyquinoline (7-BQ) metabolism and CYP3A apoprotein levels. In the case of Phase II enzyme systems, BITC increased epoxide hydrolase and GST activity and a similar

Abstract:
New organotin compounds containing alkoxy- functionalities have been prepared. The methods of preparation of the tetraorganotin species have involved three routes. Hydrostannation reactions using triphenyltin hydride have resulted in the synthesis of triphenyltin derivatives of a series of alkoxy- substituted allyl ethers. The addition of tin IV chloride, diphenyltin dichloride and phenyltin trichloride to alkoxy- substituted aryl- and benzyl- Grignard reagents have also been successful. Alkoxy- substituted benzyltin compounds have been prepared by following an alternative preparation of benzy

Abstract:
The work in this thesis consists of three related studies. (i) Further investigations have been made into the mechanism of the photochemical reaction between (Mn[sub]2(CO)[sub]8{PBu[sub]3}[sub]2) and benzyl halides, equation 1. A previous study in these laboratories, which included an (Mn[sub]2(CO)[sub]8{PBu[sub]3}[sub]2) + PhCH[sub]2Cl -->(MnCl(CO)[sub]4PBu[sub]3) + (Mn(PhCH[sub]2)(CO)[sub]4PBu[sub]3) 1 examination of reaction kinetics, led to the suggestion that the mechanism involved CO dissociation from the manganese dimer, followed by metal-metal bond homolysis and subsequent reaction of

Abstract:
In the present work, a series of 1-benzyl-2-alkylbenzenes functionalized was subjected to intramolecular cyclization reaction promoted by iron(III) chloride with diorganyl dichalcogenide allowed the synthesis of 9-(organochalcogen)-5H-benzo[7]annulenes whereas the mutual action between diorganyl dichalcogenide and iron(III) chloride in a 0.5:1.0 mole ratio was essential in order to achieve the maximal yields of the products. The cyclization reaction tolerated a variety of functional groups, such as trifluoromethyl, chloro, fluorine and methoxyl, in both 1-benzyl-2-alkynylbenzenes and diorganyl

La presente Memoria se orientó al estudio y caracterización electro-analítica de una serie de derivados N-(4-R-benzoil)-2-(2-nitrofenil)-1-H-benzimidazoles como sustratos de interés biológico. Los compuestos estudiados fueron sintetizados a partir de 2-(o-nitrofenil)-benzimidazol, generado por condensación entre 1,2-diamino-benceno y 2-nitrobenzaldehído. Posterior reacción del benzimidazol con una serie de cloruros de aroílo, generó la serie de cuatro N-(4-R-benzoil)-2-(2-nitrofenil)-1-H-benzimidazoles en buen rendimiento (R = NO2, Cl, F), con la excepción del producto denominado PMNB (R =
