ジャーナル フリーAntibacterial action, in vitro, of 2-imino-4-thiazolidone (I), 2-thio-4-thiazolidone (II), 2-oxo-4-thiazolidone (III), and 2-hydrazono-4-thiazolidone (IV), possessing fundamental structures of 4-thiazolidone derivatives, was tested and (IV) was found to be better than the other three. 5-Acetaminobenzal-2-imino-(V), 5-acetaminobenzal-2-thio-(VI), and 5-acetamino-2-oxo-4-thiazolidone (VII) were also found not to possess strong inhibitory action against bacteria. For in vitro tests against tubercle bacilli, a basic Kirchner medium in which asparagin was substituted with sodium glutamate and the amount of glycerol was increased to twice the usual volume, was used. Under the assumption that pyridine would be used as a solvent, its effect on human, bovine, and avian type tubercle bacilli was examined and it was found that it had no effect on the bacillary growth at a concentration below 1%.抄録全体を表示PDF形式でダウンロード (444K) -

ジャーナル フリーBy the condensation of p-acetaminoanisole and chloral in conc. sulfuric acid, 5-acetamino-2-methoxyphenyltrichloromethylcarbinol (I), m.p. 236.7° (decomp.), and bis (5′-acetamino-2′-methoxyphenyl) trichloromethylmethane (II), m.p. 240° (decomp.) (Chemical Abstracts, 44, 3952 (1950) gave the decomposition point 227° for a substance containing alcohol of crystallization), were obtained. Recrystallization of (II) from 90% ethanol gives a substance containing 3 1/2 moles of the water of crystallization. Thermal decomposition, action of alcoholic potash, and treating in conc. sulfuric acid at 40°, of (II) result in the liberation of one mole of HCl to give 1, 1-bis (5′-acetamino-2′-methoxyphenyl)-2, 2-dichloroethylene (VI), m.p. 232-233°, whose deacetylated compound (VII) forms pale yellow plates of m.p. 174°. Reduction of (II) with glacial acetic acid and zinc dust gives 1, 1-bis (5′-acetamino-2′-methoxyphenyl) ethane (III), m.p. 226.8°, with a small amount of fluorescent substance of m.p. 229° as a by-product. Deacetylation of (III) gives the amino compound of m.p. 129°, and removal of nitrogen from it gives 1, 1-bis (o-anisyl) ethane (IV), m.p. 68.5°. Chromic acid oxidation of (IV) gives a small amount of 2, 2′-dimethoxybenzophenone and a large amount of quinone (V), m.p. 82.9°, C15H14O3 (IV) yields a phenol when boiled with hydroiodic acid and red phosphorus.抄録全体を表示PDF形式でダウンロード (766K) -

ジャーナル フリーIt is often observed that the substitution of a part of a certain compound with allyl group often results in a substance possessing characteristics totally reverse of the original compound. Based on this idea, compounds in which allyl group was introduced into the nitrogen in barbituric acid were prepared. The compounds thus prepared, N-allylbarbital, N, N′-diallylbarbital, N-allylphenobarbital, N, N′-diallylphenobarbital, and N -allylmethylhexabital, were tested as to their antagonistic action against toxicity of barbital, phenobarbital, and methylhexabital, by their lethal dose in mice, and their action on respiration, blood pressure, and heart action in rabbit. However, none of the N-allylbarbitals possessed antagonistic action but rather showed synergistic action.抄録全体を表示PDF形式でダウンロード (1008K) -

ジャーナル フリーFree type and bonded type biotin in several kinds of crude drugs, including cinnamon and liquorice, were examined by microbiological assay method. It was found that although bonded biotin was not contained in the cinnamon, other crude drugs contained both types. In order to find out whether the biotin-like factors contained in the crude drugs, as shown by the microbiological assay, were really biotin or not, paper partition chromatography was carried out. To determine the Rf value of standard biotin, it was developed with water-saturated butanol and examined by bioassay by which it was found that biotin was developed into two groups giving Rf values of 0.2-0.3 and 0.6-0.7, and both helping growth of Lactobacillus arabinosus. Biotin-like factors of liquorice, royal jelly and Apis melifica were examined under the same conditions by which growth factors were found in those giving Rf 0.2-0.3 from liquorice and royal jelly, and Rf 0.2-0.3 and 0.6-0.7 from Apis melifica.抄録全体を表示PDF形式でダウンロード (486K) -

ジャーナル フリーPaper partition chromatography of biotin was carried out with a mixture of AcOH: H2O:BuOH (1:5:4) as the developer. Later examination by microbiological assay showed that the compound had been developed into two groups (Rf 0.6-0.7 and Rf 0.8-0.9) of substances which helped the growth of Lactobacillus arabinosus. Two-dimensional paper chromatography of the two components showed that the growth factor of larger Rf value changed to that of a smaller Rf value. It was observed that such phenomenon was affected by the heating and irradiation of ultraviolet light after spotting of biotin on the filter paper.抄録全体を表示PDF形式でダウンロード (597K) -

ジャーナル フリーSyntheses of the Brooker-type dyes were reported in Part XV and XVI of this series, but some counter-argument has been made against the conclusion of the Brooker-type structure because of the difficulty of the mutual reaction of negative anilino groups and the possibility of another substitution in this synthetic method. The conclusion of the Brooker-type dyes was made from the analytical values and absorption spectra but further proof of the formation of a Brooker-type dye by the substitution of an anilino group in the meso-position was affored by the application of ω-phenylaminovinylbenzothiazolium ethiodide or ω-phenylamino-7-methylbenzothiazolium ethiodide on binuclear trimethinethiocyanine dye possessing inactive methyl in the terminal group and anilino group in the meso-position, to a Brooker-type thiocyanine with a terminal methyl, whose absorption spectrum was similar to or the same as that of binuclear trimethine dyes. It was also experimentally proved that reaction of negative anilino groups does occur by the fact that 1, 1′-diethyl-2, 2′-trimethinethiocyanine iodide was obtained from ω-phenylaminovinyl-benzothiazolium ethiodide and benzothiazole-2-aldehyde p-dimethylaminoanil ethiodide.抄録全体を表示PDF形式でダウンロード (1214K) -

ジャーナル フリーIsolation of snake venoms by paper microelectrophoresis was carried out on 11 kinds of venomous snakes, Naja naja atra Cantor (I), Naja naja naja (II), Naja hanah (III), Bungarus multicinctus Blyth (IV), Vipera russellii formosensis Maki (V), Trimeresurus mucrosquamatus Cantor (VI), Trimeresurus gramineus stjnegeri Schmidt (VII), Trimeresurus flavoviridis flavoviridis Hallowell (VIII), Trimeresurus okinavensis Boulenger (IX), Agkistrodon acutus Guenther (X), and Agkistrodon halys blomochoffi Boie (XI). It was found that the venom from same species gave similar pattern. The venom from Naja species was composed of two or three bases and that of Agkistrodon species contained a large amount of acid proteins. Each protein on the filter paper from the venom of Formosan cobra (I) was cut out and their enzymatic action was examined. It was found that lecithinase was present in electrically neutral portion while cholinesterase was at pH 6.0, slightly to the cathodic side. Cobra venom purified by fractional precipitation with ammonium sulfate and acetone precipitation was found to be proteose, being about eight times more poisonous than the original venom, but showed no activity of lecithinase, cholinesterase, and l-ophio amino acid oxidase, being electrically almost neutral. The kinds of amino acids constituting the venoms of (I) and (X), which showed completely different electric characteristics, were examined by two-dimentional paper chromatography and paper ionophoresis by which 15 kinds of amino acids, including leucine and alanine, were detected. No difference in the kinds of amino acids constituting these two venoms was found.抄録全体を表示PDF形式でダウンロード (2090K) -

ジャーナル フリーA substance giving postitive Sakaguchi reaction was examined from the extract of Cristaria plicata Leach by paper microelectrophoresis, microbiological assay, Sakaguchi reaction, and ion exchange resins. Several kinds of guanidyl derivatives were found which had not been found in the extract of shell-fish, such as arginine, agmatin, alkain, and octopine. One of such derivatives was not adsorbed by the ion exchanger, Amberlite IRC-50, and this was a peptide-like, almost neutral substance which precipitated by phosphotungstic acid. When boiled in acid, this formed a guanidyl derivative which showed no arginine-activity with Streptococcus faecalis. The portion which did not precipitate by phosphotungstic acid also showed the presence of a substance with positive Sakaguchi reaction. This substance is almost neutral. Other substances which were detected included the peptide of arginine and a substance with positive Sakaguchi reaction which moved towards the acid side. Ninhydrin-coloring substances were examined with two-dimensional paper chromatography and 13 kinds of amino acids, including glutamic acid and aspartic acid, were found besides a fair amount of glutamine and asparagine, and a large amount of the peptide of glutamic acid.抄録全体を表示PDF形式でダウンロード (561K) -

ジャーナル フリーEffect of the oil of Thuja dolabrata and its components on pathogenic and nonpathogenic hyphomycetes was tested. Of the several components of this oil, hinokitiol was the most effective, being effective up to 64, 000 to 128, 000 dilutions against Trichophyton, Epidermophyton, and Anchorion, followed by l-rhodinic acid and thujopsol. Non-pathogenic fungi were found to be very resistant and hinokitiol was effective only in 8, 000-16, 000 dilutions. Based on the assumption that the antifungal action of hinokitiol was due to its formation of complex salts, effect of its iron, zinc, and copper salts were tested and it was found that, as in the case of oxine, the addition of iron complex resulted in complete invalidation, while that of zinc complex reduced the effect to one-quarter, and the addition of copper complex failed to bring out any difference. This specificity of the copper complex was assumed to be due to its substitution with the iron complex, as in the case of oxine.抄録全体を表示PDF形式でダウンロード (572K) -

Asymmetric methineoxonol dyes were obtained by the application of rhodanine or 2, 4-dioxothiazolidine to acetanilidomethylene compounds obtained by the acetylation of several kinds of anilidomethylene compounds. Application of p-dimethylaminobenzaldehyde, p-acetaminobenzaldehyde, or m-nitrobenzaldehyde to barbituric acid, thiobarbituric acid, rhodanine, pseudothiohydantoin, or 2, 4-dioxothiazolidine gave the corresponding benzal compounds.抄録全体を表示PDF形式でダウンロード (920K) -

ジャーナル フリーNitration of methyl dehydroabietate with conc. nitric acid in acetic anhydride results in the formation of a 8-nitro compound, m.p. 193-194°, [α]D25: +94° (acetone), and a 6-nitro compound, m.p. 135-137°, [α]D26: +80° (alcohol). The 6-nitro compound can easily be reduced to the corresponding 6-amino compound by catalytic reduction with palladium-carbon but the 8-nitro compound is resistant to this reduction. The condensation product obtained by heating at 100° an equimolar amount of methyl 6-aminodehydroabietate and ethyl ethoxymethylenemalonate was boiled in Dowtherm oil from which a compound, C27H35O5N, of prisms, m.p. 156-158°, was obtained. Since the ultraviolet absorption spectrum of this substance is similar to that of 3-carbethoxy-4-hydroxyquinoline, the structure of this crystalline substance was assumed to be the corresponding derivative of 3-carbethoxy-4-hydroxyquinoline. The yield of this substance was extremely poor, being about 5% of the theoretical amount.抄録全体を表示PDF形式でダウンロード (623K) -

ジャーナル フリーColorimetric determination of alkaloids possessing methylenedioxy group by chromotropic acid was examined and this was found to effect simplification of procedures and microdetermination compared to the existing phloroglucinol method. This method makes it possible to determine the substances in an amount 5-10γ/cc. as formaldehyde and the accuracy is within an error of ±1%. This method is also advantageous in that colored compounds and substances containing impurities could be determined in an almost colorless state by high dilution.抄録全体を表示PDF形式でダウンロード (346K) -

ジャーナル フリーEfficiency of the quantitative bridge for coloring matter has already been reported. For the determination of colorless substances, it is recommended that a developer which makes the Rf value of the substance to be near 1 be used and to use coloring matter whose Rf value is the same as that of the sample under the same conditions. The position of the sample is calculated from the relationship between the solvent front and the quantitative bridge.抄録全体を表示PDF形式でダウンロード (235K) -
