ジャーナル フリー(1) PAA添加培養中に生成されるketo acidを2,4-dinitrophenylhydrazoneとして, paper partition chromatography,溶媒に対する溶解性,吸収スペクトル,及びその他の性質を検討し,これがα-ketoglutaric, pyruvic及び少量のoxaloacetic acidの混合物であることを確認した.
(2) PAA, 2-OH-PAA添加培養と無添加培養とのketo acidの消長を比較した. PAA又は2-OH-PAA添加培養の場合に生成されるketo acidの量は,無添加培養の場合より約3倍量多いから,このketa acidがPAA又は2-OH-PAAの代謝生成物質であることが明らかである.
(3) PAA又は2-OH-PAA添加培養で生成されるsuccinic acidの量は無添加培養のそれより多いから, succinic acidも亦PAA又は2-OH-PAAの代謝生成物質の1つである.
(4) PAA否適応菌は,succinic, fumaric, malic acidのようなC4-di-carboxylic acidの代謝能を持つが, citric acid, PAA及び2-OH-PAAの代謝能を全く示さない. PAA適応菌のC4-di-carboxylic acidに対する代謝能はPAA否適応菌のそれより発達し, citric acid, PAA, 2-OH-PAAの代謝能も持つている.
(5) Pen. chrysogenum Q-176によるPAAの代謝により, α-ketoglutaric, pyruvic, oxaloacetic acidのようなketo acidとsuccinic acidとが生成される事実,及びPAA適応菌のcitric, succinic, fumaric, malic acidに対する代謝能の発達から,著者はPAAの代謝がKREBSのTCA-cycleを通して行われると推定した.又α-ketoglutaric acidの生成される点から, PAAの代謝が, 既知芳香核開裂とは全く異なつた新しい様式をとるものと推定した.

ジャーナル フリー(1) By the addition of fusarinic acid the absorption spectrum of crystalline catalase (cat. activity 30, 000) suffers considerable change, distinguished by the vanishing of λmax=625 mμ, which results from porphyrin-Fe in the catalase molecule.
(2) By the addition of fusarinic acid, the polalographic reduction wave of crystalline catalase shows a'remarkable fall.
(3) By the addition of fusarinic acid, the Redox-potential of crystalline catalase shows a remarkable fall.
(4) We found that the injurious action of fusarinic acid on catalase to be eliminated by the addition of Fe...-ion and the combination of this acid and catalase would not be broken by precipitation with cold acetone.
(5) The types of injurious action of fusarinic acid, α-picolinio acid and 2-methylpyridine-4-carboxylic acid on catalase are all entirely idential and the order of the injurious activities of these acids is as follow: fusarinic acid>α-picolinic acid>2-methylpyridine-4-carboxilic arid. This order is identical with that of the chelation's intensity. These acids all lose their injurious actions on catalase by esterification of their carboxyl-groups.
On these above mentioned facts, we concluded that fusarinic acid might tightly combine with porphyrin-Fe in the catalase molecule by the mechanism of intermolecular chelation.抄録全体を表示PDF形式でダウンロード (508K) -

ジャーナル フリーThe author synthesized the coumarin derivatives substituted an acetamino racucai at ine position of the 7 th carbon atom of 3-acetyl-4 hydroxycoumarin to examine the effect on the antibacterial activity of the negative substituent in the ben2ene nucleus of coumarin.
(1) 3-acetyl-4-hydroxy-7-acetaminocoumarin (III) and 3-acetyl-4-hydroxy-7-acetamino-8-bromocoumarin (III') were prepared by a route, which was shown schematically, using, _??_-amino-salicylic acid (V) as the starting material.
The acetylation of (V) to prepare 2-acetoxy-4-acetamino-benzoic acid (VII) was preformed by adding Ac2O to the glacial acetic acid solution of V in the presence of ZnCl2.
In this case, diacetate (VII), m. p. 183°, was obtained in a 86% yield 5% higher than the case of two-steps acetylation of (V), which was published by CARVALHO.*
Through the acid chlorides (IX and IX') of (VII) and its bromoderivative (VIII), the direct cyclization with Na-acetoacetic ester was proceeded in dry ether, heating and stirring the mixture for ten hours, and gave the yields of 38% and 30%, respectively. (III) was recrystallized three times from ethyl alcohol, in yellow prisms, and melted at 215° After two, recrystallisations from aquous acetic acid, pure (III') was obtained as yellow needles, m. p. 225°.
When the equivalent mole of sodium and acidchloride (IX, IX') were used in such a direct cyclization as it is mentioned above, it was determined that the acetyl radicals of (III) and (III') were not hydrolyzed.
(2) The rerults of the ultraviolet absorption spectra were shown in Figure 1 and 2. It is very interesting that the curves of 3-acetyl-4, 5-dihydroxycoumarin and 3-acetyl-4-hy-droxy-5-acetoxycoumarin were very similar to that of the resorcinol, when it was displ aced bathochromically.
Information of the bacterial activity of coumarin derivtives will be presented at a later date.

ジャーナル フリーIt was reported the previous paper, that several dihydrocaffeic esters were synthesized and were found-to have the marked antioxidant activity. The present work was undertaken to synthesize ω-(3, 4-dihydroxyphenyl) alkanoic esters, the related compounds to caffeic esters, in seeking further light upon the relation between the chemical structure and the antioxidant activity. These new esters are listed in the following table.
_??_To prepare homoprotocatechuic ester (VI), veratric aldehyde (I) was treated with hippuric acid, and the condensate, α-benzoyl-amino-β-veratryl-acrylic acid azlacton (III) was hydrolysed to obtain homoveratryl-pyruvic acid (IV) which was followed by dimethylation with HBr. The resulting acid (VI) was esterified by the usual way. γ-(3, 4-Dihydroxyphenyl)-butyric acid (XI) was prepared in the following way: Veratrol (VIII) was condensed with succinic anhydride in the presence of AlCl3, the resulting β-veratroyl-propionic acid (X)was treated with HI for demethylation, reduced to γ-(3, 4-dihydroxyphenyl)-butyric acid by the Clemensen reduction, and then esterified. δ-(3, 4-dihydroxyphenyl)-valeric ester (XVIII) was synthesized by the following 4 steps. γ-Veratroyl-butric acid (XV) was obtained by the condensation of veratol with glutaric anhyride. Then the reduction with the Clemensen method, the demethylation by HI and esterification were proceeded succesively. ε-(3, 4-dihydroxyphenyl)-caproic ester (XIV) was prepared through the Clemensen reduction, the demethylation by HI and the esterification of the condensation product of veratrol with polyadipic anhydride (XIX) in the presence of AlCl3. Their antioxidant activity will be published in the follow ing paper.

ジャーナル フリーTo make one approach to the solusion the relation between a chemical structure and an antioxidant activity, some ε-(3, 4-dihydroxyphenyl) alkanoic esters shown in Table 1 were examined their activities through the Active Oxygen Method.
The said alkanoic estes were synthesized by authors and the fresh lard was used as the substrate which is easy to detect its rancid odor.
The results of the experiment are shown in Table 1 and Figures 1 and 2 and are summarizedas follows:
(1) Et protocatechuate was found to be almost ineffective but a introduction of methylene groups between phenyl and carboalkoxyl groups of protocatechuic ester caused the marked enhancement in activity. The activities of most of all these compounds were proved to be superior to that of ethyl gallate.
(2) Among these compounds, methyl ε-(3, 4-dihydroxyphenyl)-caproate which had 5 methylene groups was the most effective and γ-(3, 4-dihydroxyphenyl)-butyrate having 3 methylene groups the next.
(3) Concerning the alkyl groups of esters, it was found that the order of their activities was Me>Et>n-Pr, regarding solely to ε-(3, 4-dihydroxyphenyl)-caproic ester. But this should be ascertained by using other alkanoic esters.
(4) It is noteworthy to point out that the protocatechuic ester, which was published by OSHIMA(7), to be very effective was found to be almost ineffective for the cod liver oil and lard used by authors as the substrates. A discussion on this problem was also described in this paper.

ジャーナル フリー(1) Chemical studies were made on the weathering of quartz-trachyte at Sayo-machi, Hyogo-ken and at Gendayuyama, Tottori-shi, Tottori-ken. (2) The profiles of the weathering products studied consisted of the weathered rock, light brown horizon, light brown subsoil, and brown surface soil. These soils are sandy. (3) The amount of silica decreased by degrees from the lower horizon towards the subsoil, whereas it begans to increase in the surface soil. The alumina and iron oxide gradually increased in their amount from the lower horizon towards the subsoil, but in the surface soil they began to decrease. The bases decreased slowly through the weathering. Ca was more leachable than Mg. (4) The NIGGLI's h values increased from the lower horizon towards the subsoil, and then decreased or increased slightly in the surface soil. In the subsoils, the f values were maximum, the si and si/al values were minimum, and the amount of silica, alumina, and iron oxide which were dissolved by HCI and H2SO4 were maximum. The facts showed that the iron oxide and some parts of the clay having the low si/al values-had been transferred from the upper horizon to the subsoil. (5) The results obtained from alkali solution treatment showed that the weathering products contained very little free alumina._??_抄録全体を表示PDF形式でダウンロード (378K) -

ジャーナル フリーFor the purpose of elucidating the mechanism of biochemical genetic of the yellow pigments losing mutation of Pen. chrysogenum Q 176 to Pigmentless sultant Pen. chrysogenum Q 176 ARIMA et OGASAWARA, cultural conditions of the yellow pigment production of Pen. chrysogenum Q 176 by extinction of culture media-by Pulfrich photometer, and paper-chro-matography of the pigments were examined. Effects of carbohydrate sources, nitrongen sources, C:N ratio, rate of aeration, initial pH of culture media, each representative media for penicillin production, cultural temperature, inorganic salts on the production of pigments, and inhibitive action of NaCl, relation between pH and extinction of the pigments were examined.
From the above results, the pigment production and penicillin production seemed to be parallel, but unlike in the case of penicillin, pigments does not run down rapidly after reaching its peak, but keeps its level.
By selection of cultural conditions, it was possible to increase pigment production 2 or 3 folds of the control, but not so much as 10 folds or more as in the case of penicillin production.
Next, paper chromatographic study of the yellow pigments, especially the experimental conditions were examined. Final conditions were as follows: Toyo filter paper No. 50, size 2×40cm, pretreated with SÖRENSEN phosphate buffer solution at pH. 7. 7, developing solvent (butanol 90cc, isopropanol 10cc, water 18cc (80% saturated), developing hour 17_??_18 hrs., room temperature.

ジャーナル フリーFour test organisms for B12 assay, namely, L. lactis DORNER, L. leicltmannii, Euglena gracilis var. bacillaris, E. coli mutant were compared from the standpoint of bioassay of B12. About the stability of B12 responsing quality, E. coli mutant seems to be inferior to other. three organisms. We calculated the error range of B12 standerd curve of these organisms and concluded that the accuracies of them are almost the same (error range is about 10_??_15%). As a result of factorial analysis by statistical method, we found that autoclaving conditoin is the most influencing factor for growth of lactobacilli, and for Euglena, size of inoculation is most influencing. The inhibition effect of antibiotics present in samples was studied. Two strains of lactobacilli are sensitive to inhibitory effect of penicillin and Lbacitracin, but Euglena can grow normally in presence of the antibiotics.抄録全体を表示PDF形式でダウンロード (416K)
