    Description / Table of Contents: Die Darstellung von Poly(γ-p-biphenylmethyl-L-Glutamat), PBPLG, (Poly{L-imino-1-[2-(4-biphenylmethoxycarbonyl)äthyl]-2-oxoäthylen}), (1d) wird beschrieben. Das Viskositätsverhalten dieses Polymers in Mischungen aus Benzol und Dichloressigsäure (c=0,2.10 - 3 - 1,4.10 - 3g/cm3) bei 25°CC wird untersucht. Die Ergebnisse werden verglichen mit Messungen unter den gleichen Bedingungen an Poly(γ-benzyl-L-Glutamat),PBLG, (Poly[ L-imino-l-(2-benzyloxycarbonylathyl)-2-oxoathylen]), (lc). In beiden Fallenfindet ein zweistufiger Ubergang von einer starren, von Wasserstoffbrucken stabilisiertenHelix in ein statistisches, solvatisiertes Knduel statt : PBPLG (erste Stufe CrSSX,, zweite Stufe 55-100%, Dichloressigsaure und PBLG (erste Stufe 0-70%, zweite Stufe 70-100%,Dichloressigsaure)).Die Einfiihrung eines p-Phenylsubstituenten in PBLG fuhrt deshalb in Mischungen aus Benzol- und Dichloressigsaure zu einer weniger stabilisierten Helix.Die Stabilitat und das Viskositatsverhalten von PBLG in Mischungen aus Benzol und Dichloressigsaure (c=0,2.10-3 -14.10-3g/cm3) sind denjenigen von PBLG in Mi-schungen aus m-Kresol und Dichloressigslure ( c = 1,0.10-3-4,0. 10-3g/cm3) ähnlich.
    Notes: The synthesis of poly(γ-p-biphenylmethyl-L-glutamate), PBPLG, (poly{L-imino-1-[2-(4-biphenylylmethoxycarbonyl)ethyl]-2-oxoethylene}), (1d) is described. The viscosity behavior of this polymer in benzene/dichloroacetic acid mixtures (c=0,2.10 - 3 - 1,4.10 - 3 g/cm3) at 25°CC is investigated. The results are compared with measurements on poly(γ-benzyl-L-glutamate), PBLG, (poly[L-imino-1-(2-benzyloxycarbonylethyl)-2-oxoethylene]), (1c) under the same conditions. A transition from a rigid hydrogen bonded helix to a random solvated coil occurs in two stages for both: PBPLG (first stage 0 - 55%, second stage 55 - 100% dichloroacetic acid) and PBLG (first stage 0 - 70%, second stage 70 - 100% dichloroacetic acid).Therefore, the introduction of a p-phenyl substituent in PBLG leads to a less stable helix in benzene/dichloroacetic acid mixtures.The stability and viscosity behavior of PBLG in benzene/dichloroacetic acid mixtures (c=0,2.10 - 3 - 1,4.10 - 3g/cm3) is quite similar to the behavior of PBLG in m-cresol/dichloroacetic acid mixtures (c=1,0.10 - 3 - 4,0.10 - 3 g/cm3).

    Notes: A series of imide end-capped oligoesters were prepared by reacting a number of hydroxylterminated poly(diethyleneglycol terephthalate) oligomers (X̄n ranging from 1 to 20) with N-(4-chlorocarbonylphenyl)maleimide and N-(4-chlorocarbonylphenyl)nadimide. All the oligomers were characterized by vapor pressure osmometry, 1H- and 13C-NMR and GPC. The thermal properties were also investigated and a correlation of the thermal behavior with molecular weight and the type of reactive end groups was established. Molecular models were also synthesized and characterized to obtain reliable analytical data for the determination of the oligomers composition.

    Notes: Miscible blends from plasticized poly(vinyl chloride), and epoxidized natural rubber having 50 mol% epoxidation level were prepared in a Brabender Plasticorder by the melt-mixing technique. Changes in Brabender torque and temperature, density, dynamic mechanical properties, and differential scanning calorimetry of the samples were examined as a function of blend composition. The plasticized poly(vinyl chloride)/epoxidized natural rubber blends behaved as a compatible system at all composition ranges as evident from their single glass-rubber transition temperature (Tg) obtained from dynamic mechanical analysis as well as from differential scanning calorimetry. Profound changes in the nature of the glass-rubber transition were noted with respect to blend composition. The Tg-width values of blends lie between those of plasticized poly(vinyl chloride) and epoxidized natural rubber.

    Topics: Biology
    Notes: In the fully grown Bufo arenarum oocyte, carbohydrate breakdown during the autumn-winter season is accomplished mainly through the glycolytic pathway followed by the krebs cycle. During the breeding season (spring-summer), carbohydrates are used mainly through the pentose phosphate cycle and through the variant of the Krebs cycle known as the glutamic aspartic cycle.The metabolism operating in the oocytes was determined using the following paramenters: 1) the capacity of isolated mitochondria to oxidize citrate and fumarate; 2) the enzymatic activities of phosphofructokinase (PEK) and glucose-6-phosphate dehydrogenase (G-6-PDH); and 3) cirate and ATP compartmentalization.The present paper shows that follicle-stimulating hormone (FSH) would be one of the factors responsible for summer metabolism, since ovary fractios obtained from winter specimens treated with the hormone acquired the metabolic characteristics corresponding to oocytes obtained from breeding-season animals from dose-response, and response in the function of time curves, it could be assumed that the optimum doses and times were 0.1 μg FSH/ml of incubation medium and 30 min treatment, respecitively.The metabolic effect of FSH upon oocytes could be mediaated by the adenylate cyclase cAMP system, since treatment of ovric fractions with cAMP 10-3 M reproduced the effects obtained with the hormone. In addition, 0.02 mg/ml tetracyline proved to block the effect of FSH. A direct metabolic action of FSH on body cavity oocytes (without follicle cells) was observed when submitting these oocytes to the same hormonal treatment.

    Effects of bovine mammary alpha-lactalbumin on hyperactivation and sperm-zona pellucida binding of mouse spermatozoa (1989)

    Topics: Biology
    Notes: The effects of bovine mammary alpha-lactalbumin on the motility and zona-binding characteristics of mouse sperm were investigated. Two properties of sperm associated with capacitation, hyperactivated motility, and the ability of sperm to bind to the zona pellucida of oocytes were shown to be suppressed by alpha-lactalbumin. These inhibitory effects were not accompanied by changes in the percentage of motile cells or by differences in the velocity parameters of the hyperactivated and non-hyperactivated spermatozoa. Bovine serum albumin prevented and reversed the alpha-lactalbumin-induced suppression of hyperactivation. Sperm-zona pellucida binding was partially restored by lowering the alpha-lactalbumin concentration in the medium in which sperm were allowed to bind to the zona pellucida. The results suggest that mouse sperm are decapacitated by bovine mammary alpha-lactalbumin. The counteracting effect of bovine serum albumin to the suppressive action of alpha-lactalbumin on the flagellum suggests the involvement of a mechanism different from the action of alpha-lactalbumin on the sperm head inhibiting binding to the zona pellucida.

    Description / Table of Contents: Dispiro[2.0.2.4]deca-7,9-diene and Related Model Compounds: Synthesis, U.V, N.M.R, and Photoelectron-Spectroscopic InvestigationsDispiro[2.0.2.4]deca-7,9-diene (4) and spiro[2.5]octa-4,6-diene (5 can be obtained from the corresponding monoolefins 6 and 10, respectively, by bromine addition and subsequent dehydrobromination. The u. v. spectra of 5 and 4 with λmax = 269 nm (log ε = 3.4) and 284 nm (3.7), respectively, show bathochromic shifts of their longest wavelength bands as compared to 1,3-cyclohexadiene. An analysis of the 1H n. m. r. chemical shifts and H, H-coupling constants for the olefinic protons in 4 indicates that there is no cyclic electron delocalization in this ring system. The six-membered ring in 4 is only slightly flatter than the one in 1,3- cyclohexadiene. The photoelectron spectroscopic data of 4, 5, spiro[2.5]octane (13), spiro[2.5]oct-4-ene (15), dispiro[2.0.2.4]decane (14), and dispiro[2.0.2.4]dec-7-ene (16) demonstrate the effect of the interaction between π-orbitals and cyclopropyl Walsh-orbitals; an assignment for the first bands in the p. e. spectra of these compounds is proposed.
    Notes: Dispiro[2.0.2.4] deca-7,9-dien (4) und Spiro[2.5]octa-4,6-dien (5) lassen sich aus den entsprechenden Monoolefinen 6 bzw. 10 durch Bromierung und anschließende Dehydrobromierung gewinnen. Die UV-Absorptionen von 5 und 4 mit λmax = 269 nm (log ε = 3.4) bzw. 284 nm (3.7) sind bathochrom verschoben gegenüber denjenigen des 1,3-Cyclohexadiens. Aus einer Analyse der Chemischen Verschiebungen und H,H-Kopplungskonstanten der olefinischen Protonen im 1H-NMR-Spektrum von 4 ist zu schließen, daß 4 kein cyclisch delokalisiertes Elektronensystem enthält. Der Sechsring in 4 ist nur wenig stärker eingeebnet als derjenige im 1,3-Cyclohexadien. Anhand der Photoelektronen-Spektren von 4, 5 sowie Spiro[2.5]octan (13), Spiro[2.5]oct-4-en (15), Dispiro[2.0.2.4]decan (14) und Dispiro[2.0.2.4]dec-7-en (16) wird der Effekt der Wechselwirkung zwischen π-Orbitalen und Cyclopropyl-Walsh-Orbitalen aufgezeigt; für die jeweils ersten Banden in den PE-Spektren dieser Verbindungen wird eine Zuordnung vorgeschlagen.

    Description / Table of Contents: Metallkomplexe mit Tetrapyrrol-Liganden, LIV.  -  Synthese, Spektren, Struktur und Redox-Chemie von Cer(VI)-Bisporphyrinaten mit gleichen und verschiedenen Porphyrin-Ringen im Sandwich-SystemWeitere symmetrische Cer(IV)-Bisporphyrinate werden aus Cer-(III)-acetylacetonat und Tetraphenylporphyrin, Tetra-p-chlorphenylporphyrin, und Hexadecahydrotetrabenzporphyrin hergestellt. Aus dem letzteren Porphyrin entsteht auch ein Biscer(III)-Tripeldecker; ein solcher bildet sich als einziges Produkt aus Octamethylporphyrin. Aus einem Gemisch zweier verschiedener Porphyrine, nämlich Octaethylporphyrin [H2(OEP)], und Tetraphenyl-porphyrin [H2(TPP)] oder Tetra-p-chlorphenylporphyrin [H2-(TClP)] erhält man neben den symmetrischen Spezies Ce(OEP)2 und Ce(TPP)2 die unsymmetrischen („gemischten“) Doppeldecker Ce(OEP)(TPP) oder Ce(OEP)(TClP), die verschiedene Porphyrin-Ringe im Sandwich-System haben und sich trennen lassen. Die Kristallstrukturanalyse von Ce(OEP)(TPP) zeigt CeIV in quadratisch-antiprismatischer Umgebung der Pyrrol-N-Atome der Porphyrin-Ringe. Während die IR- und NMR-Spektren der unsymmetrischen Doppeldecker-Überlagerungen der Spektren, die einzelnen Ringe darstellen, zeigen ihre UV/VIS-Spektren und die cyclischen Voltammogramme, daß die zwei unterschiedlichen Porphyrin-Ringe sich wie ein gemeinsames π-Elektronensystem verhalten. Die Darstellung der π-Kation-Radikal-Salze [Ce(OEP)2]-ClO4 und [Ce(OEP)(TPP)]SbCl6 wird ebenfalls beschrieben. In letzterem scheint sich das Defektelektron bevorzugt im OEP-Ring aufzuhalten.
    Notes: Further symmetrical cerium(IV) bisporphyrinates are prepared from cerium(III) acetylacetonate and tetraphenylporphyrin, tetra-p-chlorophenylporphyrin, and hexadecahydrotetrabenzporphyrin. In the latter case, a biscerium(III) triple-decker is also found which is the only product in the case of octamethylporphyrin. From a mixture of two different porphyrins, namely octaethylporphyrin [H2(OEP)] and either tetraphenylporphyrin [H2(TPP)] or tetra-p-chlorophenylporphyrin [H2(TClP)], besides the symmetrical species Ce(OEP)2 and Ce(TPP)2, the unsymmetrical (“mixed”) double-deckers Ce(OEP)(TPP) or Ce(OEP)(TClP) are obtained which have different porphyrin rings in the sandwich system and can be separated by chromatography. The crystal structure analysis of Ce(OEP)(TPP) shows CeIV in a square-antiprismatic geometry of the pyrrole N atoms of the porphyrin rings. While the IR and NMR spectra of the unsymmetrical double-deckers are superpositions of the spectra of the individual rings, their UV/VIS spectra and cyclic voltammograms indicate that the two porphyrin rings behave as a common π-electron system. The preparation of the π-cation radical salts [Ce(OEP)2]ClO4 and [Ce(OEP)(TPP)]SbCl6 is also described. In the latter, the defect electron seems to reside preferentially in the OEP ring.

Oberhalb 200°C lagert sich der Kohlenwasserstoff in 4,4,5-Trimethyl-1,2,5-hexatrien (10) und 5,6-Dimethyl-5-hepten-1-in (11) um. Während sich das Allen durch eine 1,5-Wasserstoffwanderung direkt aus 9 bildet, handelt es sich bei dem Alkin um ein Sekundärprodukt, das aus 10 durch eine [3,3]-sigmatrope Umlagerung entsteht. Die Aktivierungsparameter (Ea, lg A) dieser beiden Prozesse wurden im Temperaturbereich von 210-250°C ermittelt. Die erhaltenen Zahlenwerte werden diskutiert und mit denjenigen anderer konzertierter Reaktionen von Alkinen und Alkenen verglichen.
    Notes: 1-Ethynyl-2,2,3,3-tetramethylcyclopropane (9) has been prepared and subjected to gas phase pyrolysis. Above 200°C the hydrocarbon rearranges to 4,4,5-trimethyl-1,2,5-hexatriene (10) and 5,6-dimethyl-5-hepten-1-yne (11). Whereas the allene is produced directly from 9 by a 1,5-hydrogen shift, the alkyne is a secondary product formed from 10 by a [3,3] sigmatropic rearrangement. The activation parameters (Ea, lg A) for both processes have been determined for the 210 to 250°C temperature range. The data are discussed and compared with those for other concerted reactions of alkynes and alkenes.

    Description / Table of Contents: Electrophilic Opening of Photochemically Generated Bicyclo-[2.1.0]pentane Derivative - A Two-Step 3,3-Dimethylcyclopentane AnellationTricyclic compounds 7a-e with 5,5-dimethylbicyclo[2.1.0]-pentane subunits were obtained - although in poor yields - by photochemically initiated [2 + 2] cycloaddition of 3,3-dimethylcyclopropene to 2-cycloalken-1-ones 4a-e. Catalytic hydrogenation of bicyclo[2.1.0]pentanes 7a/7c proceeded regioselectively to give bicyclic compounds 17a/17c with gem-dimethyl-substituted cyclopentane units. Treatment of carbonyl-protected bicyclo[2.1.0]pentanes 16a/16c with mercury(II) acetate in THF/water or THF/methanol followed by reductive demercuration afforded - with practically quantitative diastereo-, but no recognizable regioselectivity - gem-dimethyl-substituted hydroxy- or methoxycyclopentanes 18-21, respectively. Upon warming under reflux the hydroxymercurated ketone 7c gave the regioselectively formed β-elimination product endo-7-hydroxy-8,8-dimethylbicyclo[4.3.0]non-1(9)-en-2-one (23). Upon analogous treatment, however, hydroxymercurated 7a was recovered unchanged.
    Notes: Photochemisch initiierte [2 + 2]-Cycloaddition von 3,3-Dimethylcyclopropen an 2-Cycloalken-1-one 4a-e ergab - allerdings in mäßigen Ausbeuten - die Tricyclen 7a-e mit anellierten 5,5-Dimethylbicyclo[2.1.0]pentan-Einheiten. Die katalytische Hydrierung der Bicyclo[2.1.0]pentane 7a/7c verlief regioselektiv zu den Bicyclen 17a/17c mit gem-Dimethyl-substituierter, anellierter Cyclopentan-Einheit. Die Behandlung der Carbonyl-geschützten Bicyclo[2.1.0]pentane 16a/16c mit Quecksilber(II)-acetat in THF/Wasser oder THF/Methanol und nachfolgende reduktive Demercurierung lieferte die gem-Dimethyl-substituierten endo-Hydroxy- bzw. endo-Methoxycyclopentane 18-21 mit praktisch vollständiger Diastereo-, jedoch ohne erkennbare Regioselektivität. Hydroxymercuriertes 7c ergab nach Erwärmen das regioselektiv gebildete β-Eliminierungsprodukt endo-7-Hydroxy-8,8-dimethylbicyclo[4.3.0]non-1(9)-en-2-on (23). Bei analoger Behandlung wurde hydroxymercuriertes 7a unverändert zurückgewonnen.
