Résumé :
Penta-O-acetyl-D-glucose diethyl dithioacetal monoxide 3 was obtained by oxidation of penta-O-acetyl-D-glucose diethyl dithioacetal 2 with 3-chloroperbenzoic acid. By reaction of 3 with sodium methoxide in methanol and further acetylation, 3,4,6-tri-O-acetyl-2,5-anhydro-D-mannose-diethyl dithioacetal monoxide 8 and the reduction product 3,4,6-tri-O-acetyl-2,5-anhydro-1,1-bis(ethylthio)-1-deoxy-D-arabino-hex-1-enitol 4 were obtained. Reduction of 8 yielded the corresponding dithioacetal derivative 9, which was converted to 3,4,6-tri-O-acetyl-2,5-anhydro-D-mannose diethyl acetal 11.

Résumé :
Abstract Evidence showed that acetyl groups introduced during acetic acid delignification was a primary cause of the poor enzymatic digestibility of acetic acid pulp. The inhibition by acetyl groups could be removed by saponification. Acetyl groups might inhibit the enzymes by interfering with the productive binding (hydrogen bonds) between cellulose and the catalytic domain of cellulases, by affecting the binding of CBD to cellulose, or by increasing the diameter of the cellulose chain.

Résumé :
The reactivity of the oxetane ring in 3,5-anhydro-1,2-O-cyclohexylidene- -D-xylofuranose (1) was exemplified by its regiospecific nucleophilic opening. The action of concentrated hydrobromic or hydroiodic acid on 1 resulted in the exclusive formation of the 5-deoxy-5-halo derivatives, while the action of acetyl chloride or acetyl bromide yielded the corresponding 3-O-acetyl-5-deoxy-5-halo derivatives in 70 - 90 % yield. Under strongly acidic reaction conditions, the protection of the cyclohexylidene acetal function remained intact.

Résumé :
Summary Treatment of L-biopterin (I) with N,N-dimethyformamide dimethyl- (or diethyl)acetal and then with acetic anhydride in pyridine gave 1',2'-di-O-acetyl-N'-(N,N-dimethylaminomethylene)-L-biopterin (4), which was converted by the Mitsunobu reaction into 3-methyl (5) and 3-p-nitrophenetyl derivatives (7). The protective groups on the side chain diols and N2 of these compounds were selectively cleaved to furnish products 6, 8-10, among which 9 is naturally occurring 3-methyl-L-biopterin and 8 is N',N(3)-protected biopterin, a versatile intermediate for various reactions on the side-chain diol. In contrast, the same Mitsunobu reactions of tri-N2:I',2'-0-acetyl-L-biopterin (II) afforded 04-methyl (12) and 04-NPE derivatives (13), both of which yielded 0 4-methyl-L-biopterin (14) and subsequently led to 4-amino-L-biopterin (18).

Résumé :
AbstractN,N,N′,N′-Tetramethylurea diethylacetal reacts with CH2-acidic compounds as benzylcyanide, cyanoacetic acid derivatives malonodinitrile and nitromethane to give ketene aminals or ketene-O,N-acetales. Low polar solvents favour mostly the formation of ketenaminals. The yields of ketenaminals and ketene-O,N-acetals can be improved in some cases by addition of trimethylsilyldimethylamine. The reactions of the urea acetal with diethylmalonate, ore acetyl acetone, stops at the stage of the N,N′,N″-permethylated guanidinium salts with carbanionic counterions. The formation of bis(dimethylamino)methylene-diethylmalonate from the urea acetal and diethylmalonate can be initiated by addition of trimethylsilyldimethylamine/trimethylsilylcyanide. N,N,N′,N′,N″,N″-Hexamethylguanidinium cyanide is formed in the analogous reactions of the urea acetal with N,N-dimethylcyanacetamide or diethylsuccinate. The N,N′,N″-Hexamethyl-guanidinium nitrite can be obtained from the urea acetal and nitropropane.

Résumé :
Summary Sapwood of Scots pine (Pinus silvestris L.) was acetylated with 14C- and 3H-labelled acetic anhydride. The distribution of acetyl groups was investigated with microautoradiography and microautoradiographs were evaluated with ESEM, Environmental Scanning Electron Microscopy. The investigation showed that the impregnation of wood with radioisotope-labelled substances provides a good opportunity to investigate the location of substances covalently bonded to the wood material. Introduced 14C-labelled acetyl groups show an even distribution in the wood cell wall, with no discernible concentration gradients at acetylation levels of about 5, 15 and 20% weight gain. 3H-labelled acetyl groups show an even distribution in the wood cell wall at 15 and 20% weight gain, with no discernible concentration gradients. At the 5% weight gain level, however, an uneven distribution of 3H-labelled acetyl groups over the cell wall is observed. Nevertheless, the unevenness is random and no concentration gradient is discernible at this level. 3H with a relatively high resolution, 0.5–1 μm, compared to 14C with a resolution of 2–5 μm, gives more accurate information about where exactly the acetyl groups are situated in the wood cell wall. Acetic anhydride was evenly distributed when a full impregnation procedure was used. The chemical and physical properties of acetic anhydride allow a uniform penetration into the pine cell wall and a complete acetylation takes place when the specimens are heated.

Résumé :
To determine the economic feasibility of producing acetic acid from commercial hardwood chips in kraft pulp mills, laboratory experiments were conducted to obtain sufficient data to perform a preliminary economic analysis for a proposed acetic acid recovery process. The acetyl groups in northeast hardwood were hydrolyzed from the xylan polymers in the wood to obtain sodium acetate. The extraction experiments were performed by using 4%–6% sodium hydroxide at low temperature (50°C–80°C). Sodium acetate from the extract was concentrated and then converted into acetic acid and sodium hydroxide by salt splitting using bipolar membrane electrodialysis (BPMED). Flow diagrams were prepared and cost estimates made for the capital and operating costs for the proposed acetic acid recovery process. The discounted cash flow rate of return on investment was estimated for pulp mills in the range of 1000–2000 tons/day. A preliminary economic analysis showed that the discounted cash flow rate of return on investment is primarily a function of (1) the plant size, (2) the selling price of acetic acid, and (3) the content of acetyl groups present in wood species. The income for the process and thus the rate of return on investment increases with increasing acetyl content in the wood and selling price of the acetic acid. When food grade acetic acid is produced, for example, the rate of return varies between 9% and 16% depending upon the size of the pulp mill, assuming the wood contains 3.5% acetyl groups on a dry basis and the selling price of acetic acid is US$900/ton.

Résumé :
Breast cancer is the most frequent malignancy among women, especially in Western societies. Highly penetrant genes such as BRCA1 and BRCA2, together with the reproductive history can constitute only 30% of the cause, so there should be other common genes, which may play a role in breast carcinogenesis according to one'
s lifestyle. In our case, the effect of N-acetyl transferases (NAT1, NAT2) and glutathione-S transferases (GSTM1&
GSTT1) were investigated, since variations in these genes may alter their enzymatic activity and therefore their capacity to biotransform xenobiotic compounds. To evaluate the potential association between NAT1, NAT2, GSTM1 and GSTT1 genotypes and development of breast cancer, a hospital based case-control study was conducted in a Turkish study population consisting of 37 histologically confirmed incident breast cancer cases and 34 control subjects with no present or previous history of cancer. The only recognizable difference between case and control groups is the percentage of GSTM1 deletion, 67.6% and 44.1% respectively (p=0.047). The frequency of rapid NAT2 acetylator genotype is 44.4% in cases and 23.5% in controls. Especially, women with NAT2 rapid acetylator and GSTM1 null genotypes were at the elevated risk (OR, 3.8
CI, 0.9-15.4). NAT1 rapid acetylator genotype showed no association with breast cancer. These results suggest that GSTM1 null genotype is a susceptibility factor for breast cancer, particularly in the presence of NAT2 rapid acetylator genotype.

Résumé :
O objetivo desta pesquisa foi o desenvolvimento, avaliação da estabilidade e da eficácia de formulações cosméticas contendo acetil hexapeptídeo-3 (AHP) ou acetil tetrapeptídeo-5 (ATP) ou mistura de di e tripeptídeos (DTP). Para tal, foram desenvolvidas 6 formulações à base hidroxietilcelulose (HEC), metilfenil polissiloxano (MFP) e álcool batílico e lecitina de soja (ABL) (F1), ou de HEC, MFP, ésteres de polietilenoglicol com cadeia alquílica com 12 a 20 carbonos (EP) (F2), ou de polímero de acrilatos (PA), MFP e ABL (F3) ou de PA, MFP e EP (F4), ou de HEC e MFP (F5) ou de PA e MFP (F6), contendo ou não (veículo) 10% de AHP, ou 10% de ATP ou 4% de DTP, as quais foram submetidas a um estudo de estabilidade física por determinação da reologia e a uma avaliação sensorial. Para o estudo de eficácia dos peptídeos objeto de estudo as formulações foram aplicadas nos antebraços, na face, na região dos olhos e da boca de 60 voluntárias, sendo realizadas medidas do conteúdo aquoso do estrato córneo, da perda de água transepidérmica (TEWL), do micro-relevo cutâneo e das propriedades mecânicas da pele (anisotropia), antes (basal), após 2 horas da aplicação única (efeitos imediatos) e após 15 e 30 dias de uso contínuo (efeitos a longo prazo) das formulações. Os dados foram analisados estatisticamente pelo teste paramétrico análise de variância. Nos testes de estabilidade física, as formulações de nos 1, 2 e 5 foram consideradas as mais estáveis e as formulações de nº 5 e 6 foram as que apresentaram melhor sensorial, sendo, portanto, selecionada a formulação de nº 5 como veículo para os estudos de eficácia. Na avaliação dos efeitos imediatos na pele, observou-se que as formulações estudadas proporcionaram um aumento significativo no conteúdo aquoso do estrato córneo dos antebraços, enquanto que, somente as formulações acrescidas dos peptídeos provocaram um aumento significativo neste conteúdo na face. Em relação ao micro-relevo cutâneo, as formulações contendo ou não os peptídeos provocaram uma redução do parâmetro Ser (aspereza da pele) e Rt (rugosidade) nos antebraços e a formulação contendo DTP provocou um efeito imediato significativo no parâmetro Sesm (textura da pele). Na avaliação dos efeitos a longo prazo, as formulações ocasionaram uma diminuição significativa na TEWL e as acrescidas dos peptídeos objetos de estudo proporcionaram um aumento significativo no conteúdo aquoso do estrato córneo na região dos olhos, enquanto que nos antebraços e na região da boca todas as formulações acrescidas ou não dos peptídeos ocasionaram um aumento nesse parâmetro. Em relação ao micro-relevo cutâneo, a aplicação das formulações contendo os peptídeos, na região da boca, provocou um aumento significativo nos valores de Sesm. A aplicação das formulações contendo os peptídeos objeto de estudo, nos antebraços ocasionou uma diminuição significativa da anisotropia da pele. A formulação nº 5 contendo os peptídeos objeto de estudo, apresentou efeitos imediatos na hidratação, aspereza, rugosidade e textura da pele e, efeitos a longo prazo, na hidratação, textura e anisotropia da pele, mostrando a importância do emprego destes peptídeos em produtos cosméticos com finalidades hidratantes e antienvelhecimento.
The aim of this study was the development, evaluation of the stability and the efficacy of cosmetic formulations containing acetyl hexapeptide-3 (AHP), or acetyl tetrapeptide-5 (ATP) or mixture of di- and peptides (DTP). For this purpose the 6 following formulations (F) were developed: F1- containing hydroxyethyl cellulose (HEC), methylphenyl polysiloxane (MPPS), batyl alcohol, and lecithin (BAL); F2- HEC, MPPS and C12-C20 PEG-8 alkyl ester (AE); F3- acrylate copolymer (AC), MPPS and BAL; F4- AC, MPPS and AE; F5- HEC and MPPS and F6- AC and MPPS, which were supplemented or not (vehicle) with 10% of AHP or 10% of ATP or 4% of DTP and submitted to the evaluation of physical stability by the determination of the rheologic behavior and also to the sensorial analysis. For clinical efficacy studies, formulations were applied to the volar forearm and to the face skin (eye corner and cheek region), of 60 female volunteers. Skin conditions in terms of skin moisture, transepidermal water loss (TEWL), skin mechanical properties (anisotropy) and skin microrelief, before and after 2 hours (immediate effects) and after 15 and 30-day period of daily application (long term effects). Results obtained were statistically analyzed using the ANOVA parametric test. In the rheological study, the formulations number 1, 2, and 5 were considered more stable than the others. Moreover, the formulations number 5 and 6 showed the best sensorial attributes, and for this reason the formulation number 5 was selected for the efficacy study. The evaluation of immediate effects of formulations showed that the application of the formulations studied in the volar forearm increased the water content of the stratum corneum, while only the formulations containing the peptides provoked an increased in this content, when face skin was analyzed. When the volar forearm skin microrelief was analyzed, the application of all the formulations studied provoked a significant decrease in skin roughness (Ser) and depth of roughness (Rt), furthermore only the formulation supplemented with the DTP showed a significant increase in the skin smoothness (Sesm). In the evaluation of long term effects, all formulations provoked a significant reduction in TEWL values and the formulations containing the peptides studied provoked a significant increase in the water content of the stratum corneum of eye corner; when the volar forearms and the cheek region were analyzed, all the formulations containing or not the peptides studied, provoked an increase in this parameter. When the skin microrelief was analyzed, only the formulation supplemented with AHP or ATP or DTP, provoked a significant increase in the skin smoothness (Sesm), when applied in the cheek region. The application of formulations containing the peptides studied in the volar forearms provoked a significant decrease in the skin anisotropy. The formulation nº 5 (F5) containing the peptides studied, showed immediate effects on skin hydration, roughness and smoothness, and also long-term effects on skin hydration, smoothness and mechanical properties, which demonstrated the importance of the use of these peptides in cosmetic formulations with hydration and anti-aging purposes.

Résumé :
Acetyl-CoA carboxylase was purified 750-fold from rat liver cytosol using a modified purification procedure involving high speed ultracentrifugation, sucrose density step gradients, ion-exchange chromatography and avidin-sepharose affinity chromatography. The purified preparation had a specific activity of about 2 U/mg protein and a Km of 80uM for acetyl-CoA. Silver stain of the sample separated by denaturing polyacrylamide gel electrophoresis indicated 95% of the protein migrates as a single protein band with subunit Mr approximately 230Kd. There is approximately 2% contamination of low molecular mass material and 3-5% of the protein runs as a minor band of 240Kd. As the major protein band co-migrates on SDS-po1yacry1 amide gels with immunoprecipitated acetyl-CoA carboxylase from a fresh rat epididymal fat pad tissue extract, it appears that the 240Kd band in the rat liver sample may be a pre-form of the enzyme which undergoes post-translational modification to the mature form of the enzyme. Despite appearing almost homogeneous after silver-stain, the purified enzyme preparation still contains both cyclic AMP-independent and cyclic AMP-dependent protein kinase activity, the former causing incorporation of 0.1mol Pi/mol acetyl-CoA carboxylase subunit/hr, and the latter causing incorporation of 0.5mol Pi/mol subunit/hr. Addition of specific inhibitor to cyclic AMP-dependent protein kinase effectively blocks all cyclic AMP-dependent protein kinase activity. The cyclic AMP-independent protein kinase activity co-purifying with acetyl-CoA carboxylase phosphorylates the "control sites" as demonstrated by 2 -dimensional peptide analysis of radioactively labelled ACC. This phosphorylation has no apparent effect on enzyme activity. Phosphorylation by cyclic AMP-dependent protein kinase increases phosphorylation of the control sites and also results in incorporation of [32p] into the two A peptides and one of the B group of phosphopeptides. Neither of these endogenous protein kinase activities cause incorporation of the label into the insulin responsive site of acetyl-CoA carboxylase. At least 90% of the cyclic AMP-independent protein kinase activity (assayed using ACC as substrate) in the rat liver cytosol co-purifies with acetyl-CoA carboxylase upon sucrose density gradient centrifugation. Under the conditions described, approximately 90% of this protein kinase activity is separated from ACC by DEAE-ce11ulose chromatography, eluting with the other unbound protein from this column. 2-dimensiona1 tryptic peptide analysis of acetyl-CoA carboxylase phosphorylated by this protein kinase fraction increases incorporation of [32p] mainly into the control sites. Further fractionation of this sample however does not reveal increased I site phosphorylation. Protein kinase activity eluted together with ACC (at high salt) from DEAE-cellulose appeared to lead mainly to phosphorylation of the B group of peptides. However, in this case further fractionation of the DEAE-HS fraction on casein-sepharose produces a protein kinase fraction (eluted at 0.5M KC1) which brings about phosphorylation of the insulin-directed site of acetyl-CoA carboxylase. Thus a cyclic AMP-independent protein kinase activity which phosphorylates acetyl-CoA carboxylase at an insulin responsive site, has been partially purified from rat liver cytosol. We are therefore in a position to explore the effects of insulin-directed phosphorylation on the activity of acetyl-CoA carboxylase.

Résumé :
The enzyme acetyl-CoA carboxylase catalyzes the first committed step in fatty acid synthesis in all organisms. The E. coli form of the carboxyltransferase subunit was recently found to regulate its own activity and expression by binding its own mRNA. By binding acetyl-CoA or the mRNA encoding its own subunits, Carboxyltransferase is able to sense the metabolic state of the cell and attenuate its own translation and enzymatic activity using a negative feedback mechanism. In this paper, this network of interactions is modeled mathematically using mass action kinetics. Numerical simulations of the model show agreement with experimental results.
