ジャーナル フリーAcetylation of sulfanilamide in the presence of enzyme extract of pigeon liver and coenzyme-A was tested with 47 kinds of compounds related to phenylethylacetic acid and the reaction was found to be inhibited. Relationship between chemical structure of these compounds and degree of activity was examined and following facts were found: (i) Activity tends to become stronger as the methylene chain between the phenyl and carboxyl becomes longer; (ii) there seemed to be no marked difference in activity due to stereoisomers, optical isomers, and geometric isomers; and (iii) inhibitory effect is generally stronger when the parent system has indone or naphthalene than when phenyl alone is present. The strongest inhibitory effect was found in 3-(1-indanyl)butyramide, m. p. 110.5°, among these 47 compounds.抄録全体を表示PDF形式でダウンロード (355K) -

ジャーナル フリーIn order to find the relationship between agglomeration and fluidity, sliding angle of glass beads in various liquids was measured and the result was considered with the presence or absence of agglomeration judged from sedimentation volume. Glass beads do not undergo agglomeration in hydrous polar liquids like water and hydrous alcohol, and show small sedimentation volume. Sliding angle in such a liquid is approximately constant irrespective of the viscosity, specific gravity, or surface tension of the liquid. On the other hand, glass beads undergo agglomeration in hydrous non-polar liquids like hydrous benzene at ordinary temperature (25°), has a large sedimentation volume, and a large sliding angle. The degree of agglomeration becomes smaller as the liquid temperature rises, even in hydrous non-polar solvent, and the phenomenon is accompanied by decrease in sliding angle. The degree of agglomeration can be predicted to a certain degree by the state of filling by tapping of a liquid and this value also agrees well with that of the sliding angle.
Sliding angle can be considered in two parts; the item that can be determined by the form of filling of particles and that determined from friction coefficient and adhesion force. Values for each of these items were determined for glass beads in air and adhesive force for the beads was calculated. Similar considerations were made for glass beads in liquid.抄録全体を表示PDF形式でダウンロード (909K) -

ジャーナル フリー1-Deoxy-1-p-nitroanilino-D-glucofuranuronamide (IIIa) and 1-deoxy-1-anilino-D-glucofuranuronamide (IIIc) were prepared by amidation of 1-deoxy-1-p-nitroanilino-D-glucofuranuronolactona (IIa), and 1-anilino-1-deoxy-D-glucofuranuronolactone (IIc) with liquid ammonia. (IIIa) easily underwent conversion of the lactol ring by the presence of acid or base to form 1-deoxy-1-p-nitroanilino-D-glucopyranuronamide (IVa). This was examined by paper chromatography and its result revealed that (IIIa) converted to (VIa) through an intermediate with a cleaved lactol ring, i.e. conversion from furanose to pyranose.
The amide obtained by amidation of (IIa) was acetylated to 1-deoxy-1-p-nitroani-lino-tri-O-acetyl-D-glucuronamide (Va), p-nitroanilino group was liberated to form tri-O-acetyl-D-glucuronamide (VI), and further acetylated to tetra-O-acetyl-D-glucuronamide (VII). Fusion of (VII) with phenol and p-toluenesulfonic acid afforded (phenyl tri-O-acetyl-D-glucosid) uronamide (VIII). On the other hand, (phenyl 2, 3, 5-tri-O-acetyl-D-glucofuranosid) uronamide, obtained by acetylation of (phenyl D-glucofuranosid) uronamide, was found to have the same melting point, optical rotation, and infrared spectrum as (VIII). These facts proved that (IIIa), (Va), (VI), and (VIII) are furanose.抄録全体を表示PDF形式でダウンロード (888K) -

ジャーナル フリーThe polysaccharide (IV) obtained from human tubercle bacilli, as described in Part I of this series, would be composed of 48-50 glucose units and two arabinose units, considering the result of paper chromatography of its hydrolysate (Table I), quantitative and qualitative tests with carbazole-sulfuric acid and phenol-sulfuric acid reactions, and from the mean molecular weight of (IV). Periodate oxidation of (IV) showed that the ratio of consumption of periodate, to the amount of formic acid and formaldehyde produced was 61:5.8:1 in molar ratio. Bonding positions of constituent sugars in the polysaccharide which would satisfy the above molar ratio would be 1-2 or 1-4 in glucose and 1-, 2-, or 3-position in arabinose if it were a terminal group. The mode of configuration is assumed to be a straight chain with 2-6 branchings.抄録全体を表示PDF形式でダウンロード (416K) -

ジャーナル フリーMethylation of the acetylated polysaccharide (III), reported in Part I of this series, by the Haworth-Muskat method gave a methylated compound of m. p. 101-104° (decomp.), with 44.5%, of CH3O and mean molecular weight of 9800-10500. The constituting methylated sugars were estimated by paper chromatography of its hydrolysate (Table I) and quantitatively determined by the method of Schaefer and others (Table II). Approximate estimations were made for bonding position and mode of configuration of each componental sugar in (IV) (as shown in Fig. 2) from the position of absorption in the infrared spectrum of the acetylated compound (III) (Fig. 1), amount of formic acid formed by periodate oxidation of the original polysaccharide (IV) (cf.

ジャーナル フリーStarch was oxidized with nitrogen dioxide and fuming nitric acid at a low temperature, hydrolyzed with acid, and the amount of glucuronic acid formed in the decomposition solution and the volume of carbon dioxide generated during decomposition were measured. Decarboxylation of oxidized starch is greater than that of glucuronic acid under the same condition and comparable to that of ascorbic acid and glucuronic acid osazone. Consequently, it would be difficult to consider that the oxidized starch is a glucuronic acid polymer, as was claimed by Kerr and others, and it was assumed that the molecule contained numerous labile carbonyl structures. Reduction of oxidized starch with sodium borohydride and subsequent acid hydrolysis resulted in marked decrease of carbon dioxide evolution and increase in the amount of uronic acid formed. Therefore, it was assumed that the carbonyl, in the majority, took the 2-oxo- or 3-oxo-glucuronic acid structure. The low yield of glucuronolactone by the acid hydrolysis of oxidized starch was concluded to be due to the formation of this oxo structure by secondary oxidation.抄録全体を表示PDF形式でダウンロード (988K) -

ジャーナル フリーOxidized starch, obtained by oxidation with nitrogen dioxide system agents, was oxidized with sodium periodate, the aldehyde formed was reduced with sodium borohydride, and hydrolysis of the product with acid afforded tartaric acid as crystals. Separation of this acid as barium tartrate and oxidation of the filtrate with nitric acid afforded oxalic acid as crystals. Reduction of the oxidized starch with sodium borohydride, followed by oxidation with sodium periodate, and treatment of this product as above failed to afford any of the above crystalline products. It follows, therefore, that this oxidized starch has the 3-oxoglucuronic acid groupings in its molecule and the presence of 2-oxo structure was also confirmed.抄録全体を表示PDF形式でダウンロード (657K) -

ジャーナル フリーSulfate ion in the artificial springs containing iron* inhibits Catalatic action of iron (III) ion. The rate constant of catalytic decomposition of hydrogen peroxide is not only proportional to a 1.23 power of [Fe] and inversely proportional to (H+), but also inversely proportional to 1/2 power of [∑SO42-]. Further, it is evident that oxidation-reduction potential of the same spring is proportional to the negative logarithm of 1/2 power of [∑SO42-], from the analysis of the relation between [∑SO42-] and oxidation-reduction potential.

ジャーナル フリーArtificial mineral spring containing iron alum, with a large amount of aluminium or magnesium ion has stronger catalatic action than that which dose not contain these ions. In other words, aluminium and magnesium ions promote the catalatic action of iron ion. The mechanism of this accelerative action is thought to be the inhibition of effective concentration of sulfate ion by the presence of aluminium or magnesium ion, resulting in the increase of simple iron ion concentration.抄録全体を表示PDF形式でダウンロード (432K) -

ジャーナル フリーThe catalatic action of artificial mineral spring containing sodium chloride and iron alum is weaker than that not containing sodium chloride, which shows that the catalatic action of iron is inhibited by chlorine ion as well. The degree of this inhibition is a function of sulfate ion concentration in the mineral water. There is no inhibitory action when the total concentration of sulfate ion is less than twice the total concentration of iron ion but the action appears when this becomes more than twice. The mechanism of this inhibition is thought to be the increase of effective concentration of sulfate ion by the presence of chlorine ion.
Inhibitory action of bromine ion is stronger than that of chlorine ion and is observed even when there is no inhibition by chlorine ion. Inhibition by iodine ion is 500 times greater than that of bromine ion. When liberation of iodine is observed on addition of hydrogen peroxide to mineral water, iodine promotes catalatic action. Presence of dihydrogen phosphate ion results in formation of a complex salt with ferric ion and this lowers the concentration of ferric ion, thereby inhibiting its catalatic action.抄録全体を表示PDF形式でダウンロード (724K) -

ジャーナル フリーCatalatic action of artificial mineral spring of acidic iron containing copper is in inverse proportion to the product of hydrogen ion concentration and 0.5 power of total sulfate concentration, as in the case of catalatic action of the iron spring not containing copper, and directly proportional to the total iron concentration. This fact shows that copper ion catalyzes simple iron ion but not iron sulfate ion. Therefore, artificial acid vitriol spring and acid iron alum spring, containing equal concentration of simple iron (III) concentration and copper ion, have the same degree of catalatic action. The accelerative effect of copper ion is independent of iron ion concentration and reaches. the maximum when copper ion concentration is 10-2M. At a greater concentration than this, there is no increased accelerative action of copper ion. The degree of catalatic activity becomes approximately 15 times greater, when copper ion concentration is 10-2M. Relationship between copper ion concentration and degree of acceleration is indicated by a primary sigmoid curve, p=[Cu2+]/[Cu2+]+1.8×10-6.抄録全体を表示PDF形式でダウンロード (670K) -

ジャーナル フリーZaô spring (ageless spring), a few days after welling up, and Maka mineral spring, after precipitation and ageing had taken place, have catalatic action similar to that of artificial iron spring with similar chemical composition. Inhibitory substances are hydrogen ion, sulfate ion, and chlorine ion, and Cu2+ is accelerative. In both of these natural mineral springs, inhibitory action of chlorine ion is greater than the promoting action of Cu2+. Consequently, catalatic action of a natural spring may be weaker than that of the artificial spring with similar total iron, total sulfate, and hydrogen ion concentration. Mineral spring undergoes ageing as soon as it wells up and one of its causes may be the decreased concentration of cocatalyst. Catalatic action of natural springs is approximately in inverse proportion to the hydrogen ion concentration of the mineral water.抄録全体を表示PDF形式でダウンロード (777K) -

ジャーナル フリー4-Pyridinesulfonic acid and 4-quinolinesulfonic acid were derived to the corresponding 4-amino-, 4-methylamino-, and 4-dimethylamino-pyridines and -quinolines in 60-90% yield by heating them with ammonium hydroxide, methylamine, in the presence of zinc chloride, in an autoclave at 150-160° for 20-24 hours. Similar reaction with hydrazine hydrate afforded 4-pyridyl- and 4-quinolyl-hydrazines in 70-80% yield. These hydrazines underwent condensation with acetone, benzaldehyde, pyruvic acid, and ethyl pyruvate to form 4-pyridyl- and 4-quinolyl-hydrazones, and reacted with acetylacetone to form 1-(4-pyridiyl and -quinolyl)-3, 5-dimethylpyrazole.

Reaction of 1 mole each of the oxide and sodium disulfide gives 4-mercapto-pyridine or -quinoline 1-oxide in 90% yield, while the reaction with 1 mole of sodium thiosulfate affords 4, 4′-thiodipyridine or 4, 4′-thiodiquinoline 1-oxide in 80% yield.
Heating of 4-bromopyridine 1-oxide with potassium thiocyanate in ethanol does not result in the formation of a 4-thiocyanato compound but the same reaction with 3-nitro- or 3-bromopyridine 1-oxide gives 4-thiocyanato compound in 70% yield. 4-Bromoquinoline 1-oxide also undergoes this reaction to give 4-thiocyanatoquinoline 1-oxide in 81% yield. This 4-thiocyanato compound reacts with 2N sodium hydroxide or sodium carbonate when warmed and forms 4, 4′-thiodiquinoline 1, 1′-dioxide, which when warmed with sodium sulfide or reacted with 2N sodium hydroxide at room temperature forms 4-mercaptoquinoline 1-oxide. 4-Bromoquinoline 1-oxide reacts with potassium selenocyanide to form 4-selenocyanatoquinoline 1-oxide in 83.5% yield.抄録全体を表示PDF形式でダウンロード (691K) -

ジャーナル フリーA substance affecting alkaline phosphatase activity of rabbit serum and serum calcium level was extracted and isolated from bovine Harder's gland. The gland was extracted with 0.01N ammonia water and fractionated into three fractions with ethanol. The gland was also extracted with 2% saline solution and fractionated into three fractions with ammonium sulfate. Examination of physiological activity of these fractions showed that fractions A-40, CS-3, and CS-5 increased alkaline phosphatase activity and decreased calcium level, while fractions A-44, A-80, and CS-10 lowered the phosphatase activity, and fractions A-80 and CS-10 effected transitory increase of serum calcium level with subsequent lowering. These results seem to partly prove the assumption that the Harder's gland was excreting a substance which increases or decreases alkaline phosphatase activity, as part of its physiological function. All of these fractions were considered to be a protein from the analysis of their total nitrogen and color reactions.抄録全体を表示PDF形式でダウンロード (705K) -

Treatment of (II) with ammonia in methanol affords 1-(3-aminothioureido)-1-deoxy-β-D-glucopyran-uronamide (IV) whose condensation with aldehyde also gives (VI). Infrared spectra of (II), (II′)-(VI) exhibit thioureido absorption at around 1530cm-1 and of (II) and (III) the asymmetric stretching vibration of C-O-C in the β-pyranose ring at around 1080cm-1. In vitro antituberculosis action of (V) and (VI) was not any better than the aromatic aldehyde thiosemicarbazones used as the control.抄録全体を表示PDF形式でダウンロード (832K) -

ジャーナル フリーThe racemic compound of menisperine (I), the aporphine-type base contained in Menispermum dauricum DC., and the racemic compound of N-methyllaurotetanine (II), the aporphine-type base in Litsea cetrata BL., were synthesized earlier. It was shown at that time that the Pschorr reaction of phenanthrene cyclization had afforded, besides the objective aporphine-type bases and benzyltetrahydroisoquinolinetype base by further progress of deamination, a structurally unknown compound as colorless needles, m.p. 81-83°, during the synthesis of dl-menisperine (I) and that the same compound of colorless needles, m.p. 81-83°, and another structurally unknown compound had been obtained as colorless prims, m.p. 167-169°.
In the present series of work, examinations were made on these two kinds of structurally unknown substance and the compound of m.p. 81-83° was identified as 2-methyl-6, 7-dimethoxy-1, 2, 3, 4-tetrahydroisoquinoline (VI) and that of m.p. 167-169° as 5-benzyloxy-6-methoxy-1H-indazole (X).
This has shown that another example has been provided by this Pschorr reaction to the fact already pointed out by Tomita and Kitamura that, during the synthesis of aporphine-type bases by Pschorr's phenanthrene cyclization reaction, an abnormal side-reaction occurs by which the molecule is severed into two upper and lower fragments.抄録全体を表示PDF形式でダウンロード (452K) -
