JOURNAL FREE ACCESSSince Schneider and Weltheim reported about the essential oils in garlic in 1892, many researchers have studied on its essential oils. Recently Stoll isolated odorless alliin from garlic and found this compound changed to odory allicin with the garlic enzyme. In this paper, isolation method of one kind of thioglycoside from garlic was reported. At first, garlic bulbs were treated with boiling water, crushed and extracted with methanol at a room temperature, and then thioglycoside was adsorbed on active carbon to exclude the concomitants. According to the color reactions and analyses, this compound was proved as R-CH : CH-CH2-S-C6H8O6·1/2Ca, in which R was a peptide containing a new amino acid, and carbohydrate part was calcium fructuronate. Its aglycon showed some sterilization effects for E. coli.View full abstractDownload PDF (614K) -

JOURNAL FREE ACCESSIn the previous paper, scordinin A1 was isolated from boiled garlic, and it was seemed as the biological active component in garlic. In this paper the constituents of scordinin A1 were described from the hydrolysis products of scordinin A1. By acid hydrolysis of scordinin A1, fructuronic acid was detected, and by garlic enzyme allyl mercaptan was proved. And by hydrolysis with barium hydroxide, one kind of peptide, scormin, was isolated. From the above results, the author presumed that allyl thiofructuronic acid combined with scormin to form scordinin A1, and on the chemical structure of scormin will be discussed in Part III in this series.View full abstractDownload PDF (444K) -

JOURNAL FREE ACCESSRing opening reactions with some bases were examined in the following quaternary salts : 2-ethyl-3, 4-diphenylisoxazolium chloroferrate (V), and 2, 4-dimethyl-3-phenyl-, 3, 4-diphenyl-2-methyl- and 2-methyl-3-phenylisoxazolium perchlorate (IXa, b and c). Treatments of V and IX with sodium alcoholate in alcohol gave the corresponding alkyl cinnamates (VIIa-e). By the use of aqueous sodium hydroxide, V and IXb gave the respective cinnamic anhydrides (Xa and b) contrary to the report of Kohler, et al., and IXa gave an unexpected product, 2, 5-diphenyl-1, 3, 4-trimethylpyrrole (XIa) along with usual ring cleaved products, XIIa and XIIIa. Reactions of IXa, b with several amines gave β-keto acid amides (XIIc-h), the ketones (XIIIa, b) and the pyrrole (XIa) (only from IXa), respectively. Reactions of IXa with Grignard reagents gave 5-substituted △3-isoxazolines (XIVa, b). Similar 5-amino-△3-isoxazolines (XVa-c) were obtained by cautious treatment of IXa, b with piperidine or morpholine. Solvolysis of X, XIV and XV were also investigated, and a tentative mechanism for the formation of the various products are presented.View full abstractDownload PDF (907K) -

JOURNAL FREE ACCESSThe accumulation of acetoin in the culture medium of Saccharomyces carlsbergensis was specific with m-I deficiency. Its concentration in 48 hour culture medium reached to 8 μmoles/mg of dry cell and the ratio of acetoin production by the m-I deficient yeast to that by the normal yeast (m-I supplemented) was found to be 100-1000 in 48 hour cultivation in one of four media tested. Casein hydrolysate used as nitrogen source in the medium, changed this ratio greatly by their lots. pH during the cultivation changed slightly (between 4.5 and 5.0) and it gave no significant effects on acetoin accumulation. Addition of increased amount of ammonium sulfate to the medium gave an adverse effect on the growth of m-I deficient yeast and accelerated the acetoin accumulation. While the addition of cofactors for pyruvate oxidation such as lipoic acid, had no reducing effect for acetoin production, the addition of thiamine was critical for it in m-I deficient Saccharomyces carlsbergensis.View full abstractDownload PDF (720K) -

JOURNAL FREE ACCESSImproved syntheses of 1, 4-dihydroxypyrido [3, 4-d] pyridazine (II) and 1, 4-dichloropyrido [3, 4-d] pyridazine (I) were described. Reaction of I with alcohol and alkali gave 1, 4-dialkoxypyrido [3, 4-d] pyridazines (IIIa-c). Hydrolysis of I gave an isomeric mixture of 1-chloro-4-hydroxy- and 1-hydroxy-4-chloropyrido [3, 4-d] pyridazines (IV and V). Reaction of I with hydrazine hydrate afforded also an isomeric mixture of 1-chloro-4-hydrazino- and 1-hydrazino-4-chloropyrido [3, 4-d] pyridazines (VIII and IX). The structures of these compounds were determined by an alternative synthesis of V from known 1-hydroxy-4-aminopyrido [3, 4-d] pyridazine (VI) and by conversion of IX into V. Also described were the preparations of 1-hydroxypyrido [3, 4-d] pyridazine (VII) and isopropylidene derivatives (X and XI) of VIII and IX, and improved syntheses of 1, 4-dichlorophthalazine and ethyl 3-cyanoisonicotinate.View full abstractDownload PDF (840K) -

JOURNAL FREE ACCESSThe effect of anti-inflammatory drugs on leucocyte migration and vascular permeability during acute inflammation was examined in lathyritic rats by carboxymethylcellulose pouch method. The above mentioned two unit reactions, especially leucocyte migration, in inflammation locus were promoted in lathyritic rats compared to normal rats. Inhibition pattern of protein exudation showed significant difference between normal and lathyritic groups in case of steroidal anti-inflammatory drugs. Forty percent inhibition in lathyritic rats was observed 3 hr after the injection of corticosteroids, while in normal rats there was no inhibition until 6 hr. There was no marked difference between these two groups in non-steroidal antiinflammatory drugs. The inhibitory effect of steroidal and non-steroidal anti-inflammatory drugs on leucocyte migration was almost the same as in the normal rats or slightly stimulated in lathyritic rats.View full abstractDownload PDF (644K) -

JOURNAL FREE ACCESSUltraviolet absorbance versus temperature profile has been examined of seven helical nucleic acids in aqueous solutions with and without poly-L-ornithine. The hyperchromicity observed at the melting temperature of each nucleic acid is found to be lowered linearly as the amount of poly-L-ornithine added to the solution. This fact is taken as indicating that there is a stoichiometric complex of polyornithine plus nucleic acid formed. The ornithine/nucleotide mole ratio was determined to be 1/1 for the complexes of calf thymus DNA, 3) poly dAT, rice dwarf virus RNA, and poly rAU. The ratio was found to be 2/3 for the complexes of poly (A+U) and poly (A+2U), and 1/2 for the complex of poly (I+C).View full abstractDownload PDF (847K) -

JOURNAL FREE ACCESSOn the way of the study to improve the in vivo antibacterial activity of nitrofuran compounds, it was found that the some N-oxide derivatives of (5-nitro-2-furyl) vinyl heterocycles had the superior in vivo activity to the corresponding original compounds. To clarify whether such tendency was observed in general, thirteen (5-nitro-2-furyl) vinyl heterocycles and their N-oxide derivatives were co mpared on their oral protective effects in mice and additionally on the in vitro antibacterial activities and the plasma levels in rats. It was generally observed that the N-oxide derivatives were superior to the corresponding original compounds in the protective effects. Such superiority seemed to be partially attributed to the increase of the in vitro antibacterial activities and the plasma levels of the N-oxide derivatives.View full abstractDownload PDF (533K) -

JOURNAL FREE ACCESSFirst, 2-, 3-, and 4-(trifluoromethyl) quinoline 1-oxides (IV, V, and VI) were synthesized. Next, their reactions with acetic anhydride and phosphoryl chloride and the Reissert reaction were carried out and compared with the reactions in the cases of pyridine series. The reactions of IV with acetic anhydride and phosphoryl chloride gave 4-substituted products, whereas in the cases of V and VI 2-substituted products were obtained. In the Reissert reaction of IV, the starting material was recovered ; in the cases of V and VI, 2-nitrile derivative was produced as well as a considerable amount of 2-hydroxy derivative as by-product. Then, the reaction of V with only potassium cyanide in methanol was carried out to obtain 3-(trifluoromethyl) cinchoninonitrile. The unique result as above was concluded to be due to the naphthoid structure of quinoline.View full abstractDownload PDF (718K) -

JOURNAL FREE ACCESSCatalytic hydrogenation of calcium D-xylo-5-hexulosonate (5-keto-D-gluconate) has been investigated on transition metal catalysts with special interest in the selective formation of calcium L-idonate. The reaction completed usually within several hours under 20-100 kg/cm2 hydrogen pressures at 80°. Initial rates on a Raney nickel catalyst were represented by dC/dt=k'PH20.5 where C is the degree of conversion. Nickel, ruthenium and palladium gave rise to more L-idonate especially when prepared from their salts by treating with sodium borohydride. For example, 73% of the hydrogenated products was L-idonate on a "boron-modified-palladium"catalyst.View full abstractDownload PDF (573K) -
