JOURNAL FREE ACCESSAlbocycline, C18H28O4, is a neutral antibiotic produced by Streptomyces sp. The physico-chemical properties indicated that it was one of the macrolide antibiotic consisting of only macrocyclic lactone without any carbohydrate moiety. Analytical and spectral data on albocycline, its acetate and ozonolysis products made it possible to assume that albocycline possessed a hydroxy, a methoxy, a lactone, three olefinc linkages and also four branched-methyl groups. From these data the partial structure of albocycline was suggested as illustrated in Chart 1 and 3.View full abstractDownload PDF (611K) -

JOURNAL FREE ACCESSBy the catalytic hydrogenation of albocycline at room temperature four hydrogenation products were obtained. Two of them, II and III, were confirmed to have 14-membered lactone and 5-membered lactone structure respectively from infrared (IR) and nuclear magnetic resonance (NMR) spectral data. They were the isomer and correlated to each other. These correlations suggested the position of a hydroxy group in albocycline. II was derived to the corresponding hydrocarbons (IV) by complete hydrogenation, of which mass spectra suggested the carbon skeleton and branching pattern of methyl group. From these results and the 100 MHz NMR spectral data of albocycline and its acetate, the structure of albocycline was finally proposed as Ia.View full abstractDownload PDF (588K) -

JOURNAL FREE ACCESSBy the catalytic hydrogenation of albocycline in acetic acid under high pressure at elevated temperature, nine reaction products were obtained. They were classified into pairs by their infrared (IR), nuclear magnetic resonance (NMR) and mass spectral data. The eluci dation of structures of these pair products gave the conclusive answers about the positions of O-functions, especially that of a methoxy group, in albocycline molecule. Thus, the structure of albocycline was finally confirmed as Ia.View full abstractDownload PDF (700K) -

JOURNAL FREE ACCESSRacemic Trimetoquinol [dl-1-(3, 4, 5-trimethoxybenzyl)-6, 7-dihydroxy-1, 2, 3, 4-tetrahydroisoquinoline (I)] hydrochloride was administered to rabbits and rats by intravenous injection and the metabolites excreted into the 24 hr urine pools were investigated. Unchanged I and five metabolites, dl-1-(3, 4, 5-trimethoxybenzyl)-6-methoxy-7-hydroxy-1, 2, 3, 4-tetrahydroisoquinoline (II), dl-1-(3, 4, 5-trimethoxybenzyl)-6-hydroxy-7-methoxy-1, 2, 3, 4-tetrahydroisoquinoline (III) and glucuronides of I, II and III were identified. Species differences between rabbit and rat were observed in the capacity of O-methylation and in the ratio of the two O-methylated isomers. In rabbits, a majority of administered I appeared as glucuronide of I, whereas glucuronide of III occupied the highest proportion in rats.View full abstractDownload PDF (977K) -

JOURNAL FREE ACCESSDehydrogenation of lindenenyl acetate (Ib) by palladium was studied. The reaction was found to proceed directly to a final product (linderazulene (II)) by a main route, and partly to II via a dihydroazulene intermediate (IV), by a concerted mechanism. Dehydrogenation of Ib in deuteropentane showed that palladium has properties of both a dehydrogenation and a hydrogenation catalyst under N2, at 300°.View full abstractDownload PDF (1026K) -

JOURNAL FREE ACCESSβ'-Haloethyl isopropylidene-α-glycerophosphoryl 2-chloromethyl-4-nitrophenyl phosphates (10 and 11) were prepared by the stepwise phosphorylations of ethylene halohydrin and 1, 2-isopropylidene-glycerol with 2-chloromethyl-4-nitrophenyl phosphorodichloridate (3), a phosphorylating reagent having an "activatable" protecting group. The protecting group of 10 and 11 was readily and selectively removed by hydrolysis through an active intermediate 14 derived from the reaction of 10 and 11 with various tertiary amines to afford the corresponding isopropylidene-α-glyceryl β'-haloethylhydrogen phosphate (15) along with 2-hydroxy-5-nitrobenzyl trialkyl ammonium chloride (16), a chip of the active intermediate 14. The halogen atom in the ethyl chain of the phosphate 15 reacted with tertiary amine at the same time to afford the corresponding quaternary ammonium compound 17 which was converted by subsequent hydrolysis into α-glycerophosphoryl choline (1a) and its analogues (1b-d). Thus, DL-α-glycerophosphoryl choline (1a), its L-isomer (1a-L), inner salt of β'-(DL-α-glyceryl hydrogen phosphoroxy) ethyl triethyl ammonium hydroxide (1b), 1-[β'-(DL-α-glyceryl) hydrogen phosphoroxy] ethyl 1-methyl piperidinium hydroxide (1c) and inner salt of 1-[β'-(DL-α-glyceryl) hydrogen phosphoroxy] ethyl 1, 4-diazonia bicyclo [2, 2, 2] octane hydroxide (1d) were prepared in good yield. DL-Myristoyl lecithin (18) was prepared by acylation of 1a with myristoyl chloride to confirm the structure of synthetic 1a.View full abstractDownload PDF (1032K) -

JOURNAL FREE ACCESSThe oxidation of L-ascorbic acid with Ti3+-H2O2 has been investigated by a rapidmixing flow technique coupled with electron spin resonance. Two kinds of spectra were distinguished, one of them being not reported hitherto. To assign these electron spin resonance spectra, the oxidation of hydroxytetronic acid, a simple analog of L-ascorbic acid, was further investigated. In the light of the obtained electron spin resonance parameters possible radical structures were discussed.View full abstractDownload PDF (467K) -

JOURNAL FREE ACCESSThe effect of cupric ion on the stability and antibacterial activity of penicillins, benzylpenicillin and 2, 6-dimethoxyphenylpenicillin, in phosphate buffer solution and phosphate broth kept at pH 5.0 was investigated. The degradation was found to obey first-order kinetics to produce the corresponding penicillenic acids, though the formation of penicilloic acid analogs have been postulated in other studies. Catalytic and complexing effect of cupric ion on the stability of penicillins was revealed in relatively lower and higher concentrations of the metal ion respectively, where an appreciable difference in the effect was noted between buffer solution and broth. Apparent stability constants for the proposed complex between penicillins and cupric ion were estimated to be log Kapp=2.65 and 2.91 with benzylpenicillin and 2, 6-dimethoxyphenylpenicillin, respectively. The antibacterial activity against Staphylococcus aureus was not apparently affected by the addition of cupric ion, which indicates an apparent lack of correlation between the stability and the activity of the drug in broth. This is presumably because the probable enhancing effect of the metal ion on the cell wall permeability of the penicillins outweighs the other effects investigated.View full abstractDownload PDF (797K) -

JOURNAL FREE ACCESSIrradiation of 3α, 5-cyclo-6-oxo-17β-acetoxy-5α-androstan-19-oic acid (1) in tertiary butyl alcohol yielded 4α-tert-butoxy-6, 6-dihydroxy-17β-acetoxy-5α-androstan-19-oic acid 6, 19-lactone (2) and 6-oxo-17β-acetoxyandrost-4-en-19-oic acid (3) in 50% and about 10% yields respectively. The former (2) was found to be formed by photochemical addition of tertiary butyl alcohol to the α, β-unsaturated ketone system in the latter (3). In connection with the mechanism of the above reaction, photolysis of 6-oxo-17β-acetoxy-5α-androstan-19-oic acid (9) in methanol and tertiary butyl alcohol is conducted to yield 5, 6-secocarboxylic acid derivatives (17, 19, 20, 21), and irradiation of methyl 3α, 5-cyclo-6-oxo-17β-acetoxy-5α-androstan-19-oate in tertiary butyl alcohol was also described yielding methyl 4α-tert-butoxy-6-oxo-17β-acetoxy-5α-androstan-19-oate (4) and methyl 6-oxo-17β-acetoxyandrost-4-en-19-oate (14).View full abstractDownload PDF (1083K) -

JOURNAL FREE ACCESSIn the present paper, it has been described on a relationship between the fluorescence emission and the carbonyl stretching frequency of flavone derivatives. Non-fluorescent ligands (type I, III in Chart 1) show their carbonyl frequencies in the 1645-1650 cm-1 region, while fluorescent ligands (type II, IV) give those in the 1610-1620 cm-1 region and cause a remarkable increase of the fluorescence intensity by forming of chelates with some metals such as beryllium, aluminum, magnesium, thorium, yttrium. Further evidence is found by examining the chemical shift of 2-proton in several chromone derivatives. That of 3-hydroxychromone is noteworthily lower than those of the other chromone derivatives, indicating the more aromaticity of its pyrone ring. From these data, it is concluded that introduction of a hydroxyl group into 3-position of flavone causes the remarkable lowering of carbonyl frequency and the increase of aromaticity of pyrone ring, which is very likely responsible for the fluorescence emission.View full abstractDownload PDF (486K) -

JOURNAL FREE ACCESSThe N-demethylation of five antihistaminics possessing diemethylaminoalkyl group was compared in in vitro production of formaldehyde by liver 9000 g supernatant fraction from four animal species, rat, mouse, guinea pig and rabbit. Sex difference was observed in only rats but the demethylating activities varied from species to species for a drug and from drug to drug in a species. The high demethylating activities were shown for trimeprazine or diphenhydramine by rats and for fenethazine or chlorpheniramine by rabbits. In adult male rats, castration or SKF 525A reduced the activities and 19-nortestosterone phenylpropionate enhanced the activities without the big change in relative order. Phenobarbital induced the activities of female rat liver in almost same proportion for every drug but 3-methylcholanthrene did not show stimulatory effect. The formaldehyde production from N-oxides was comparatively small and did not show the difference among drugs. No correlation between the lipid solubility and the N-demethylation was found. The significance of investigation of species differences in the drug metabolism was discussed.View full abstractDownload PDF (782K) -

JOURNAL FREE ACCESSThe permeation of phenothiazines through cellulose membrane was investigated as a successive study of the adsorption from aqueous solution reported in a previous paper. The permeability decreased with the increase in molecular weight of phenothiazines. The activation energy of permeation was close to those of diffusion of usual organic medicinals in water. Any remarkable effect of pH on the permeation was not observed in the present conditions. It was demonstrated from these results that the permeation of phenothiazines through cellulose membrane proceeds on the basis of a diffusion through pore. In comparison with the diffusion constant of levomepromazine maleate in aqueous solution evaluated from the dissolution rate by the rotating disk method, the interaction coefficient of the diffusion through cellulose membrane was given as 0.453.View full abstractDownload PDF (565K) -
