ジャーナル フリーAbsorption, distribution and excretion of tritiated p-biphenylmethyl-(dl-tropyl-α-tropinium) bromide (3H-BTTB) in the rat were investigated. After the intravenous injection of 3H-BTTB, half life of the radioactivity in blood was 7 min at first 30 min. Higher radioactivities were incorporated in kidney, liver, pancreas and spleen. Almost negligible radioactivity was seen in amniotic fluid or fetus. After the intramuscular injection of 3H-BTTB, 6.62% and 60.16% of the radioactivity were excreted in urine and feces, respectively, at 96 hr. The fact may indicate that 3H-BTTB is mainly excreted in bile. It may be suggested that these behaviors in biological disposition are attributed to have a large molecular weight and to be a quaternary ammonium compound.抄録全体を表示PDF形式でダウンロード (612K) -

ジャーナル フリーA solution of imidazole in dichloromethane developed blue color immediately by an addition of a solution of tetracyanoethylene in the same solvent at the temperature of lower than 0°. The color turned to yellowish brown when the temperature of the mixture was allowed to rise to higher than 0°. A mixing of both solutions at room temperature produced yellowish brown solution, directly. The mixture separated reddish brown crystals when it was stand at room temperature for about 30 min. The absorption maxima at 400 and 418 mμ of the crystals were proved to be attributable to 1, 1, 2, 3, 3-pentacyanopropenide anion, and this absorption spectrum was shown to be almost identical with that of the reaction mixture mixed at room temperature. 4(5)-Methyl-, 4(5)-phenyl- and 4, 5-diphenylimidazole gave similar results. The chemical structures of these crystals were clarified as imidazolium and substituted imidazolium 1, 1, 2, 3, 3-pentacyanopropenide from the results of elemental analyses, infrared spectra, nuclear magnetic spectra, titrations with sodium hydroxide solution, and from the detections of imidazole and imidazole derivatives on thin-layer chromatogram developed by a basic solvent.抄録全体を表示PDF形式でダウンロード (625K) -

ジャーナル フリーBiguanide derivatives were allowed to react with acetylacetone and benzoylacetone. Both of alkyl and arylbiguanides reacted with acetylacetone to give the corresponding 4, 6-dimethyl-2-alkyl or arylguanidinopyrimidine. On the other hand, arylbiguanides were found to exhibit chemical behaviors different from alkylbiguanides toward benzoylacetone. Two moles of arylbiguanides reacted with benzoylacetone to give 6-arylamino-4-amino-2-phenyl-2(6'-arylamino-4'-amino-2'-methyl-1', 2', -dihydro-s-triazinyl-2'-methyl)-1, 2-dihydro-s-triazine, though alkylbiguanides gave 6-methyl-4-phenyl-2-alkylguanidinopyrimidine under the similar condition. It was noted that the reaction of 1-methyl-1-phenyl-biguanide with benzoylacetone resulted in the formation of 6-methyl-4-phenyl-2-methyl-phenylguanidinopyrimidine without formation of any expected bisdihydro-s-triazine.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Four reaction products (I, II, III and IV) were separated in the color reaction of pyruvic acid with p-dimethylaminobenzaldehyde in an aqueous sodium hydroxide-dimethylsulfoxide solution at the reaction temperature of 40°or 60°, and their structures and roles in the colorimetric method of pyruvic acid determination previously presented were investigated. I was obtained from the reaction mixture resulted at the reaction temperature of 40°and determined as the trans form of p-dimethylaminobenzalpyruvic acid. The absorption spectral data showed that I was the sole coloring matter in the method of pyruvic acid determination. II, III and IV were produced in the reaction at 60°, and II and IV were purified as their methyl esters. They were characterized as 5-(p-dimethylaminophenyl)-isophthalic acid derivatives as shown in Chart 1, and proved not to be related to the coloration. The reaction pathways to form those products were also discussed.抄録全体を表示PDF形式でダウンロード (781K) -

ジャーナル フリーMore than 80% of the acetylcholinesterase present in porcine erythrocyte membrane could be released from it by repeated washing with hypotonic buffer, as was true in the case of bovine erythrocyte. Density-gradient centrifugation revealed that the released enzyme particles of either species of mammals have a similar density of about 1.07 which is significantly lower than that of the original stroma. It has phospholipid and cholesterol contents higher than those of the stroma. Introduction of dinitrophenyl residue to the outer surface of the erythrocyte membrane caused about 60% inhibition of the acetylcholinesterase activity in all of human, bovine and porcine erythrocytes. Penicillin bound to the erythrocyte membrane exerted almost complete inhibition of the enzyme activity in all cases. These results suggest that acetylcholinesterase of similar nature is present in a form of lipoprotein on the outer surface of the erythrocyte membrane, with a density lower than that of the main part of the membrane.抄録全体を表示PDF形式でダウンロード (666K) -

ジャーナル フリーMethylation of 3-α-pyridyl-1, 2, 4-triazoline-5-thione (II) with methyl iodide in alkaline solution gave 5-methylthio-3-α-pyridyl-1, 2, 4-triazole (III) and its N-methyl derivatives, 1-, 2-, and 4-methyl-5-methylthio-3-α-pyridyl-1, 2, 4-trizaole (IV, V and VI). The structures of these compounds were established by elemental analysis, spectral data and the identification with the compounds prepared by different methods. IV, V and VI were also produced by methylation of III with methyl iodide in alkaline solution. Methylation of III with dimethyl sulfate in alkaline solution or diazomethane in methanol also gave the same products. The ratios of the amount of IV : V : VI in the products were determined by nuclear magnetic resonance spectroscopy and it was found that IV was predominantly formed in every case.抄録全体を表示PDF形式でダウンロード (703K) -

ジャーナル フリーDecarboxylation of oxalacetic acid (OAA) by metal chelates was examined, using copper (II) as a metal and seven kinds of ligand, which forms N, N-coordinated five membered ring chelate, used were 6, 6'-dimethyl-α, α'-dipyridyl, 4, 4'-dimethyl-α, α'-dipyridyl, α, α'-dipyridyl, 5-nitro-ο-phenanthroline, ο-phenanthroline, 4, 7-dimethyl-ο-phenanthroline, and ethylenediamine. When the concentration ratio of dipyridyl to copper (II) was varied, 1 : 1 ratio of copper to dipyridyl effected the fastest decarboxylation rate of OAA, and the rate was faster than that by copper (II) ion alone. Effect of each ligand on the reaction rate was examined and the reaction rate fell in the order of α, α'-dipyridyl, ο-phenanthroline, and ethylenediamine ; 5-nitro-ο-phenanthroline, ο-phenanthroline, and 4, 7-dimethyl-ο-phenanthroline ; α, α'-dipyridyl, 6, 6'-dimethyl-α, α'-dipyridyl, and 4, 4'-dimethyl-α, α'-dipyridyl. When the acetate buffer concentration was 0.1M, the reaction rate was faster, the smaller the pKa, and greater the catalytic effect. When the buffer concentration was 1.0M, the above order did not hold. It was also revealed that steric effect of the ligand affected this reaction. The intermediate formed in this decarboxylation reaction was examined by the measurement of ultraviolet and infrared spectra, and by isolation of this intermediate, and formation of a mixed chelate compound of OAA, copper, and ligand was confirmed.抄録全体を表示PDF形式でダウンロード (728K) -

ジャーナル フリーMepyrizole (DA-398) was found to have the two crystalline forms of anhydride and dihydrate. Aqueous solution which contain more than 5 per cent of mepyrizole separate into two liquid layers at temperatures above 45°. It was found from the results of thermal analysis that crystal of mepyrizole dihydrate is transformed into anhydrous form at about 46°. Phase diagram of mepyrizole/water system was obtained by summarizing the results of solubility studies, hygroscopic equilibriums and thermal analysis. Such abnormalities in the vicinity of 46°can be explained as based on the transition between mepyrizole anhydride and dihydrate and the mutual solubility of mepyrizole anhydride and water. From the results of calorimetric analysis, the endothermic reaction given after the dissolution reaction is deduced to the hydration reaction of mepyrizole anhydride in solution. Consequently, the dissolution phenomena of mepyrizole anhydride can be explained as follows : mepyrizole anhydride [MP]solid first dissolves quickly in water as anhydride [MP]aqueous and then gradually changes into dihydrate [MP.2H2O]aqueous.

ジャーナル フリーThe reductive cleavage of sulfur containing organophosphorus compounds and its application to the analysis of organophosphorus pesticides were examined. Cidial, malathion, and dimethoate having a common structure (CH3O)2P(S)SR were treated by Raney nickel in ethanol. The non-phosphorus products characteristic to each of the original pesticides were formed, and they were identified with ethyl phenylacetate, diethyl succinate, and N-methylacetamide, respectively. Px which is a main phosphorus containing product common to these pesticides was identified with the phosphorus compound obtained by the same treatment of dimethyl dithiophosphate. The structure of Px and the reaction mechanism were discussed. It was also proved that this reaction afforded a new method to characterize this type of organophosphorus pesticides.抄録全体を表示PDF形式でダウンロード (693K) -

ジャーナル フリーN-Alkylhydroxylamines are shown to be easily oxidized to corresponding nitroso compounds with lead tetraacetate in benzene. The N-alkylhydroxylamines are found to react with equimolar lead tetraacetate and corresponding alkylnitroxides are detected during the oxidation. These results propose a mechanism in which lead tetraacetate acts as a hydrogen abstracting oxidant and the N-alkylhydroxylamines are oxidized to nitroso compounds via corresponding alkylnitroxides.抄録全体を表示PDF形式でダウンロード (554K) -

ジャーナル フリー"Pharbitic acid" (I), the component glycosidic hydroxyfatty acid of pharbitin, was found to be a mixture of two minor and two major constituents, pharbitic acids A, B, C (II) and D (III). II and III were isolated by silica gel chromatography of their p-phenyl phenacyl esters and subsequent saponification. II, mp 120-129°, [α]D -51.4°, C44H78O26·10H2O, is composed of ipurolic acid, two moles each of D-glucose and L-rhamnose and one mole of D-quinovose, and III, mp 140-145°, [α]D -63.8°, C50H88O30·2H2O, has another mole of L-rhamnose. Oxidation of I with Na2Cr2O7 and treatment with AcONa in boiling Ac2O both followed by acid hydrolysis provided respectively 10-hydroxytridecan-2-one (VI) and 11-hydroxytetradec-2-enoic acid (VII) as the sole ether soluble product indicating that II and III are 11-O-oligosides of ipurolic acid. On oxidation with NaIO4 and subsequent acid hydrolysis, III provided D-quinovose, while II yielded none, and partial hydrolyses of I, II and III yielded equally monoglucoside (XI), [α]D -16.2°, C21H40O9·H2O, diglucoside (XII), mp 114-116°, [α]D -23.6°, C27H50O14·1/2 H2O, and rhamnodiglucoside (XIII), [α]D -25.7°, C33H60O18·H2O. On the basis of the above results together with those of gas chromatographic analyses of aglycones and component monosaccharides of the permethylates of II, III, XII and XIII, II and III are assigned the structures either one of IIa-c and IIIa-c, respectively.抄録全体を表示PDF形式でダウンロード (1018K) -
