JOURNAL FREE ACCESSThe reduction product of 2-ketocularimine (III) with lithium aluminum hydride was submitted to alumina chromatography and cularimine (I), 2-hydroxycularimine (IX), and III were obtained. IX was acetylated with acetic anhydride and pyridine to a diacetyl compound (X), while Eschweiler-Clarke reaction of IX gave the N-methyl compound (XI) and dehydration of IX with phosphorus pentoxide afforded XV, whose reduction produced I. 2, 3, 6-Trimethoxydibenz [b, f] oxepin-10 (11H)-one was synthesized and its Pomeranz-Fritsch reaction with polyphosphoric acid gave 6, 9, 10-trimethoxy-12H benz [6, 7] oxepin-[2, 3, 4-i, j] isoquinoline (XX), whose oxidation with pyridine-chromic acid complex produced a ketone compound (XVII) identical with the product obtained by oxidation of cularimine with pyridine-chromic acid complex. Catalytic reduction of XX gave a product agreeing with authentic sample of cularimine.View full abstractDownload PDF (1012K) -

JOURNAL FREE ACCESSSeparatory determination of isoniazid (INAH) and its degradation products, isonicotinic acid (INA), isonicotinamide (INAA), and 1, 2-diisonicotinoylhydrazine (Bis) was established. (1) INAH is determined colorimetrically using sodium 1, 2-naphthoquinone 4-sulfonate. (2) Separation of INA is effected by passing the sample solution through a column of a weak cation-exchange resin (Amberlite CG-50 (H+ form)), by which INA alone is not absorbed, and INA in the effluent is determined colorimetrically using cyanogen bromide. (3) After sample solution is oxidized by ferricyanide in alkaline medium, the reaction mixture is passed through a column of a strong anion-exchange resin (Dowex 1×8 (Cl- form)), by which INAA is unchanged and not absorbed by the resin. The effluent is brought to pH 1 and INAA is determined by measurement of UV absorbance at 263mμ. (4) Bis is determined by measurement of absorbance at 329mμ of sample solution brought to pH 8.9 by adding 0.05M borate buffer solution and substracting the absorbance of INAH, which is calculated from concentration of INAH separately obtained by colorimetry with sodium 1, 2-naphthoquinone 4-sulfonate.View full abstractDownload PDF (810K) -
Syntheses of Asymmetrical Bromo- and Iodo- trihydroxyfluorans and Their Reactions with Metal IonsItsuo Mori1965 Volume 85 Issue 8 Pages 679-685

JOURNAL FREE ACCESSSeveral new non-symmetric trihydroxyfluoran derivatives substituted with bromine and iodine in 2′-, 4′-, and 2′, 4′-position were synthesized by the method previously reported through condensation of 3-halo- (III), 5-halo- (I), or 3, 5-dihalo-2, 4-dihydroxybenzoylbenzoic acid (II) with phenols (pyrogallol, phloroglucinol, and o-hydroxyhydroquinone triacetate). Coloration pH range of these 18 kinds of bromo-and iodo-trihydroxyfluorans was measured (Table I). The bromo derivatives (Nos. 1-9) generally showed more bathochromic coloration than the iodo derivatives (Nos. 10-18) and intensity of the coloration increased in the order of 4′-halo, 2′-halo, and 2′, 4′-dihalo derivatives.
Examinations were made on the relationship between pH range and coloration in the reaction of bromo- and iodo-trihydroxyfluoran derivatives with metal ions (Table II). It was thereby found that, as in the case of chloro derivatives, the metal ions could be divided into three large groups according to the reaction of the solutions in which they undergo coloration; Bi, Th, Hg in acidity, Pb, Co, Cd, Ni, Zn, La, Cu in neutral to slight acidity, and Mg, Ca, Ba, Al, Sr in alkalinity. The number of metal ions reacting with the iodo derivatives were less than those reacting with the bromo derivatives, and their coloration was generally hypsochromic.View full abstractDownload PDF (927K) -

JOURNAL FREE ACCESSFrom the color reaction of hydroxyfluorans and its halogen derivatives with metal ions, 3′, 4′, 5′, 6′-and 2′, 3′, 6′, 7′-tetrahydroxyfluoran, and 2′-, 4′-halo-and 2′, 4′-dihalo-3′, 6′, 7′-and 3′, 5′, 6′-trihydroxyfluorans were found to undergo sensitive coloration. Examinations were made on the color reaction of 3′, 5′, 6′-trihydroxyfluoran, 3′, 4′, 5′, 6′-tetrahydroxyfluoran, amino acetic acid and iminodiacetic acid complexones of hydroxyfluorans, and their derivatives substituted in 2′-, 4′-, or 2′, 4′-positions with chlorine, bromine, and/or iodine with metal ions (Hg2+, Th3+, Bi3+, Zr4+, In3+, Ce3+, La3+, Cd2+, Zn2+, Cu2+, Co2+, Ni2+, Ba2+, Sr2+, Ca2+, Mg2+). 3′, 4′, 5′, 6′-Tetrahydroxyfluoran, hydroxyfluoran complexones, and bromo and chloro derivatives of 3′, 5′, 6′-trihydroxyfluoran were found to form colored complex in high sensitivity, and the tone of color was deep, especially in the case of 2′, 4′-disubstituted 3′, 5′, 6′-trihydroxyfluoran, and change of color in the chelate titration was also very sensitive. Coloration of iodine-substituted 3′, 5′, 6′-trihydroxyfluoran with a metal ion was hypsochromic and color change was also indistinct. Good indicator quality was found in Bi3+, Hg2+, Th3+, Cd2+, Co2+, Zn2+, Cu2+, Ni2+, La3+, Pb2+, and rare earth metal ions.View full abstractDownload PDF (932K) -

JOURNAL FREE ACCESSThe quantity T to be measured by a turbidimeter equipped with an integrating sphere is the ratio of diffuse transmitted light to that of total transmitted light, corrected by a term due to turbidity of the medium and condition of the apparatus. In a turbid colored system, the T value decreases slightly as absorption increases, because the path length of diffuse transmitted light is a little longer than that of parallel transmitted light.
The correction factor F is the ratio of T for colored system to that for colorless system containing the same scattering particles. As a result of experiment using 0.3% sodium lauryl sulfate solution of a latex and Methyl Orange, the factor F could be expressed as a function of optical density D and T value for the colored system: F=A1-A2D+A3T+A4DT. This expression was supported by a theoretical calculation where Rayleigh equation is applicable.
It was concluded that when a certain turbid colored solution is given, T value for a colorless system can be obtained from optical density D and T for the colored turbid system if the coefficients in the factor F were determined beforehand about this turbid system.View full abstractDownload PDF (874K) -

JOURNAL FREE ACCESSExaminations were made on the antagonism between oxytocin and 64 kinds of amino acids, amines, peptides, and phenolic compounds. It was found that l-thyroxine, triiodo-l-thyronine, l-diiodotyrosylglycine, l-tyrosyltyrosine derivatives, and a few phenolic compounds were antagonistic to the uterus-contracting action of oxytocin, vasopressin, serotonin, and urinary oxytocic substance when examined by the excised rat uterus, and that pretreatment with these compounds and thyroidectomy increased the wave height of contraction and the amount required for antagonism. When using excised uterus of a guinea pig, thyroxine was antagonistic but not diiodotyrosylglycine or tyrosine ethyl ester, and the contraction was effected by 2, 4-dinitrophenol, all indicating difference according to animal species. Thyroxine was found to antagonize the anaphylaxie contraction of guinea pig uterus. Examination was also made on the antagonistic action with serotonin, using the ileum of a rat and a guinea pig, and it was found that phenolic compounds and l-tyrosyltyrosine derivatives were antagonistic with both animals, while thyroxine was antagonistic when using a rat ileum and not with guinea pig ileum. From these facts, it was considered that thyroidal hormone and compounds related to it must be taking some part, in some form, in the contraction mechanism of smooth muscles.View full abstractDownload PDF (1097K) -

JOURNAL FREE ACCESSThe analgesic activities of 1, 4-bis (phenoxyacetyl) piperazine and its derivatives substituted with various groups in both phenyl groups were tested in mice by the pressure method. At the same time, the effect of these compounds on climbing test (measured by Sandberg's method) and barbital anesthesia in mice was studied.
In regard to analgesic action, the following results were obtained. When the phenyl rings were substituted with one alkyl, methyl- and propyl-substituted compounds showed a potent activity, but action of ethyl substituted one was very weak. Among methoxyl-substituted derivatives, specific depression of analgesic activity was observed when methoxyl was substituted in the ortho position in the phenyl ring. No analgesic action was observed in hydroxy-substituted compounds. When two groups were substituted in both phenyl rings, only the following three compounds showed analgesic actions: 2-methoxy-4-allyl, 2-methoxy-4-propyl, and 2-methoxy-4-ethoxycarbonyl derivatives. When a halogen was substituted in phenyl rings, only the monochloro derivatives showed analgesic activity, and this activity was not influenced by the position of chlorine in the phenyl rings.
Potent depressing activities of climbing in mice were observed only in o-chloro and o-bromo derivatives, and activities of other compounds were very weak. The compounds which showed inhibitory action on climbing response generally possessed prolonging action on barbital anesthesia.
The climbing inhibiting actions of AP-38 and AP-41 were more potent when these were injected intraperitoneally, and activities were depressed extremely by oral treatment.View full abstractDownload PDF (696K) -

JOURNAL FREE ACCESSIn the synthesis of 10α-alkylaminoacylphenothiazine, the aminoacyl groups used were R=N-CH2-CO-, CH3CH(N=R)-CO-, R=N-CH2-CH2-CO-, CH3-CH2-CH(N=R)-CO-, (CH3)2-CH-CH2-CH(N=R)-CO-, and C6H5-CH2-CH(N=R)-CO-, and the amines used for them were dimethyl-, diethyl-, isopentyl-, and β-phenethyl-amines, tyramine, piperidine, piperatine, and morpholine. Application of morpholine to 10-(2-bromisovaleryl) phenothiazide failed to give the aminated product but gave 10-(dimethylacryl) phenothiazine, m.p. 158-159°, probably due to steric hindrance. Application of ethanolamine to 10-(chloracetyl) phenothiazine resulted in its decomposition into N, N-bis (2-hydroxyethyl) glycine, m.p. 195°, and phenothiazine.View full abstractDownload PDF (577K) -

JOURNAL FREE ACCESSSyntheses of 5-substituted-1, 3, 4-oxadiazole derivatives in various ways are described. Although 5-nitro-2-furohydrazide (I) gave 2-(5-nitro-2-furyl)-5-methyl-1, 3, 4-oxadiazole (X) by refluxing with acetic anhydride, its vinylog (II) did not yield the corresponding 1, 3, 4-oxadiazole (XIV) under the same condition. On the other hand, II gave 2-[2-(5-nitro-2-furyl) vinyl]-1, 3, 4-oxadiazole (XI) by refluxing with ethyl orthoformate, but I did not yield the corresponding compound (III) under the same condition.
2-(5-Nitro-2-furyl)-5-aryl (or furyl)-1, 3, 4-oxadiazoles and their vinylogs were obtained by refluxing of the corresponding diacylhydrazines with phosphoryl chloride in a good yield, but the yield decreased markedly when aryl or furyl group in the 5-position was replaced by an alkyl group. Antimicrobial activities of these nitrofuran compounds are presented in Tables III to V.View full abstractDownload PDF (931K) -
