ジャーナル フリーAnodic synthesis of saturated alicyclic compounds was carried out. Dihydroalepric acid and homodihydroalepric acid, analogs of chaulmoogric and hydnocarpic acids, were prepared by the mixed Kolbe reaction of cyclopentylacetic acid and half-ester of dibasic acid. ω-Cyclohexylhexanoic acid was obtained by the cross-coupling of cyclohexylacetic acid with methyl hydrogenadipate. 1, 2-Dicyclopentylethane and 1, 2-dicyclohexylethane were identified as the symmetrical coupling product of cyclopentylacetic acid and cyclohexylacetic acid, respectively.抄録全体を表示PDF形式でダウンロード (538K) -

ジャーナル フリーStreptomyces akiyoshiensis novo sp., which was isolated from a soil sample collected at Akiyoshido, Yamaguchi Prefecture, produced a new antibiotic, C5H9O4N, active solely against pathogenic tubercle bacilli including strains resistant against streptomycin, INAH, and other hitherto known antituberculosis antibiotics and chemotherapeutics. This antibiotic was assumed to be a new neutral amino acid having a non-conjugated carbonyl group in the molecule and the structure of δ-hydroxy-γ-oxo-L-norvaline was proposed. From the chemical structure, the name HON was given to this new antibiotic.抄録全体を表示PDF形式でダウンロード (447K) -

ジャーナル フリーThe structure of δ-hydroxy-γ-oxo-L-norvaline was proposed for the new antibiotic, HON. This compound was synthesized through two different routes. Optical resolution of the racemate was achieved by fractional crystallization of brucine salts of N-acetyl-δ-hydroxy-γ-oxo-DL-norvaline. Physicochemical and microbiological properties of the synthesized δ-hydroxy-γ-oxo-L-norvaline revealed that this compound was identical with naturally occurring L-HON.抄録全体を表示PDF形式でダウンロード (647K) -

ジャーナル フリーSeventy strains of type culture and more than 300 bacterial strains isolated from drainage were tested for their properties to excrete purine compounds in their culture fluid using nonexacting purine auxotrophs of E. coli. Several strains thus selected excreted a considerable amount of ultraviolet-absorbing substances in their culture fluid. Examination by paper chromatography revealed that ultraviolet-absorbing substances consisted mainly of nucleotides having adenine, guanine, uracil, or cytosine as the base.抄録全体を表示PDF形式でダウンロード (576K) -

ジャーナル フリーNucleotides in the culture fluid of Brevibacterium liquefaciens novo sp. were adsorbed on charcoal, eluted with 50% ethanol containing 2% of conc. ammonia, and were submitted to column chromatography on Dowex-1 (chloride). Each nucleotide was isolated as calcium or ammonium salt and identified. Following nucleotides were identified : Cytidine 5'-phosphate, adenosine 5'-phosphate, cytidine 5'-pyrophosphate, uridine 5'-phosphate, adenosine 5'-pyrophosphate, and a uridine 5'-pyrophosphate-acetylhexosamine-peptide compound. The last compound gave alanine, glutamic acid, lysine, and an Elson-Morgan reaction-positive substance on paper chromatogram after it was hydrolyzed by acid.抄録全体を表示PDF形式でダウンロード (677K) -

ジャーナル フリーAction of aminated azaindolizines on Lactobacillus casei and Streptococcus faecalis was compared with that of several diaminopyrimidine compounds. All compounds exhibited more pronounced effect on St. faecalis than on L. casei. Growth inhition caused by these compounds was reversed in the decreasing order by thymine, leucovorin, and folic acid. These results suggested that C=N bond between 1- and 8a-positions in 1-azaindolizine molecule might have an effect similar to amino group on the lactic acid bacteria.抄録全体を表示PDF形式でダウンロード (541K) -

ジャーナル フリーThe properties of the third hyhroxyl group in metagenin (I) and epimetagenin (IIIa) were examined. From the results of acylation reaction and acid treatment, it was confirmed that the third hydroxyl group in metagenin had an equatorial and the epimeric one in epimetagenin had an axial conformation. Metagenin formed a δ-lactone ring by the opening of A-ring and was approximately confirmed as 5β, 25D-spirostane-2β, 3β, 11α-triol.抄録全体を表示PDF形式でダウンロード (764K) -

ジャーナル フリーHydrogenation of 2 (1H)-pyridones was carried out in methanol over Raney nickel at 120 atm. and 200∼240°and gave 2-piperidone derivatives. When the reduction temperature was raised to 280°, hydrogenation of carbonyl group took place, followed by N-methylation of the resulting piperidine derivative was observed. On the other hand, when the reaction temperature was kept below 180°, the starting material was recovered unchanged. By the action of acetic anhydride on 4-ethylpyridine 1-oxide, 4-(1-hydroxyethyl) pyridine and 4-ethyl-3-hydroxypyridine were obtained, while 4-methoxycarbonylpyridine 1-oxide gave 4-methoxycarbonyl-2 (1H)-pyridone.抄録全体を表示PDF形式でダウンロード (531K) -

ジャーナル フリーFor the detection of compounds having enolisable or phenolic β-diketone group, the method employing uranyl ion was found to be recommendable by the fact that it is more selective and sensitive than the known methods using titanium (III) or iron (III) ion which gives color reaction both with β-diketones and phenols. The reaction with uranyl ion proposed here is based on the formation of a colored chelate compound which is stable in an acetic acid medium.抄録全体を表示PDF形式でダウンロード (468K) -

ジャーナル フリーN, N'-Alkylidenebisacetamide, such as N, N'-methylenebisacetamide, N, N'-ethylidenebisacetamide, and N, N'-benzylidenebisacetamide, reacted smoothly with 2, 4-xylenol by the interaction of phosphoryl chloride, affording N-(α-alkyl-2-hydroxy-3, 5-dimethylbenzyl) acetamide by substitution of α-acetamidoalkyl group, in a good yield. Effect of the amide residues in N, N'-alkylidenebisamide on the reaction was examined with N, N'-methylenebisformamide, -acetamide, -propionamide, and -benzamide. The general reaction sequence was presumed and found to be characterized by the formation of a nitrile as a by-product corresponding to the one amide residue in N, N'-alkylidenebisamide.抄録全体を表示PDF形式でダウンロード (584K) -

ジャーナル フリーExaminations were made on the pollens of Forsythia koreana and other species by paper chromatography in an attempt to confirm the pollen flavonoid component of forsythia which has two types of flower, one being short-styled and the other, long-styled. It had been reported that rutin is present in the pollens from the former and quercitrin in the pollens of the latter, and that a satisfactory fertilization would be prevented without the action of these different glycosides of quercetin. However, as far as the present series of experiments were concerned, it was found that rutin is solely present as the flavonoid pigment, and glucose and fructose as the free sugars. Lactose was not detected from any of the pollens.抄録全体を表示PDF形式でダウンロード (532K) -

ジャーナル フリー1) The prevention of hydrolysis of ester, using methantheline bromide (Banthine) as an example, with surfactants was examined. Surfactants used were anionic, cationic, and nonionic. Anionic surfactant (sodium laurylsulfate) markedly prevented the hydrolysis (the half life becomes 100 times longer in 0.5% laurylsulfate solution) and nonionic surfactant prevents it slightly. 2) Hydrolysis in sodium laurylsulfate solution does not follow a pseudo-first order course and is influenced by a buffer concentration. 3) The higher the concentration of sodium laurylsulfate, the slower became the hydrolysis.抄録全体を表示PDF形式でダウンロード (662K) -
