4-Dimethylamino-substituted nitro-and nitrosobenzene and 4, 4'-bis(dimethylamino)-substituted azoxy-and azobenzene have been shown to react with the distillable liquid formate, TMAF, composed of formic acid and trimethylamine to give a number of the products, N-methyl and N-formyl derivatives of p-phenylenediamine. Control experiments with several substrates, mostly nitrobenzene derivatives, and with the other formates and formic acid have been made, revealing source of the increasing N-methyl of the products and some features of the reaction.

In the presence of Cu and 2-(2-hydroxyethyl)pyridine, flufenamic acid formed a chelate compound, which could be extracted with propyl acetate. The amount of flufenamic acid was obtained indirectly by measuring Cu in this propyl acetate solution by atomic absorption. When this method was applied to the perfusion of the rat small intestine and to the analysis of preparations, good results were obtained without any interference. It was also found that flufenamic acid, Cu, and 2-(2-hydroxyethyl)pyridine combined in the ratio of 1 to 1 to 1 to form a chelate.

The new mesoionic compounds, anhydro-2-benzyl-1-mercapto-3-methyl-9-oxo-(9H)-imidazo[1, 5-a]indolium hydroxide, was synthesized by the reaction of 1-acetyl-3-indolinone, carbon disulfide, and benzylamine. The structure has been determined by an X-ray analysis. The Crystals are monoclinic, a=11.58, b=8.52, c=15.50 Å, β=102.7°, and the space group is P2
1/C. The intensities of all independent reflections were measured with a Rigaku auto differactometer and a total of 887 were collected and employed for structure determination by the heavy atom method. The final R factor is down to 0.067 by a block diagnal least-squares refinement. The mesoionic imidazolium ring system is almost planar. The C-S bond of 1.678 Å agrees well with the accepted value of 1.78 Å, methyl group of 1.449 Å attached with an imidazolium ring indicates some double bond character.

The reaction of methyl 1-cyano-2-methylthio-3-nitrocrotonate with equimolar amount of amine gave methyl 2-hydroxy-3-amino-5-oxopyrroline-4-carobxylate which was replaced methylthio with amino group and with ring closure. However, with excess amine gave amine salt of nitro group, and also replaced with methylthio group. The raction of pyrroline derivatives with active methylene compounds gave the corresponding substituted compounds.

Alkylation of adenosine 1-oxide (I) and its 2', 3'-O-isopropylidene derivative (V) with alkyl halides in N, N-dimethylacetamide furnished the corresponding 1-alkoxy derivatives (IIa-f). The free bases, obtained from IIa-f, readily underwent rearrangement to give the isomeric N
6-alkoxy derivatives (IVa-f) when heated in water. Treatment of 1-benzyloxyadenosine perchlorate (IIc : X=ClO
4) with water at pH 9.5 and 39-41°for 4 hr afforded the ring-opened intermediate (IIIc)(79% yield), which was recyclized in hot water (pH 7) to IVc. In alternative synthesis of IVa, b, c, condensation of 6-chloro-6-β-D-ribofuranosylpurine (VIa) with the appropriate alkoxyamines proceeded smoothly. Removal of the isopropylidene group from IVe under acid conditions or exchange amination of adenosine with ethoxyamine at pH 5 also yielded N-ethoxyadenosine (IVb).

The methylene protons at 5 and 7-position of the ring of 6 appeared as a AB system quartet. All ring methylene protons in 2 gave a singlet. The temperature dependent coalescence and splitting of the singals was observed in 1. At low temperature the 5, 7-methylene protons in thr ring of 1 gave a AB quartet and a singlet. From these facts it was suggested that 1 was amixture of the conformational isomer A and B in Fig. 8 and they could not freely rotate each other even at room temperaute. 6 existed only as the structure A. The Mass spectra of them were also reported.

5MgBr. The mechanism of these reactions was clarified by the studies by the ESR technique. The spectrum of 9-phenylthioxanthyl radical (VI), which was a reaction intermediate, was analyzed by the McLachlan SCF-MO computation.

Pharmacological properties of the extracts from the magnolia cortex (the bark of Magnolia obovata THUNB.) were examined with special reference to their central nervous system action. The ether extract of the magnolia (1g/kg i.p.) markedly depressed the spontaneous activity of mice and chicks, while the water extract (1g/kg i.p.) procuced prompt paralysis of respiration. Distinct muscle weakness was found after administraction of the ether extract, through the clinging power test on the wire net, and was different from the effect of the water extract. The ether extract supressed convulsion produced by strychnine, picrotoxin, or pentetrazol. Tremor by oxotremorine was also blocked by the ether extract. Pentetrazol infusion technique was employed for the elucidation of the mode of this drug action. Depressive effect of the ether extract was also exerted on the crossed extensor reflex of the chick spinal cord.

Isolation and characterization of biliary metabolites of SA-504, a new anticholinergic drug, were studied in rats. More than 70% of the radioactivity excreted in 3 hr bile of rats given
14C-SA-504 was found to be due to metabolites. Fifteen metabolites were separated from bile of rats dosed with
14C-SA-504, and eleven metabolites were characterized. Most of characterized metabolites were conjugated with GSH, cysteinylglycine, cysteine or N-acetylcysteine. The presence of the glycol derivative of SA-504 and tertiary amine N-oxide of SA-504 as minor metabolites was demonstrated. The oxidation of SA-504 by rat liver microsomes suggested that the epoxide was formed as an intermediate. From these facts, it seems likely to conclude that metabolic pathways of SA-504 consists of epoxidation, GSH conjugation and hydration of the epoxide, cleavage of C-C bond, N-demethylation and N-oxidation and the the main metabolic pathway of SA-504 is epoxidation followed by GSH conjugation.

Effects of surfactants on the thiol-disulfide exchange reaction consisting of thiamine disulfide compounds and thiols were studied as a model system representing changes in drug's stability which would be caused by drug-surfactant interaction. Addition of sodium laurylsulfate, sodium glycocholate or polysorbate 80 to the raction mixture caused, in their own way, a decrease or an increase in the rate of the reaction. The effective factors affecting on the surfactant effects were found to be lipophilic character and structure of the disulfide compounds and also the kind of thiols, e.g. glutathione, cysteine, cysteamine or thiophenol.

Pharmacokinetics on the metabolism and excretion of tolbutamide (TB) following the rapid intravenous injection of TB was investigated in rabbits based on the kinetic model where TB is first oxidized to 1-butyl-3-p-hydroxymethylphenylsulfonylurea (HTB), which is secondly converted to 1-butyl-3-p-carboxyphenylsulfonylurea (CTB) and both the metabolites are excreted in urine. It was found that binding of TB to plasma proteins and/or blood cells could not be neglected and the excretion of HTB formed in body would be well interpreted by assuming an intervenient compartment between blood and urine. Furthermore, pharmacokinetics of HTB was investigated after the administration of HTB to rabbits. It became clear that the amount of CTB formed in body after the administration of HTB was far smaller than that formed in body after the administration of TB indicating that the assumption that a metabolite administered per se would behave in the same manner as the metabolite formed in body from its precursor is not always free from criticism, though it has been undoubtedly employed to many pharmacokinetic studies of drugs. On the contrary, it was suggested that CTB administered per se would behave samely in body as CTB formed through metabolic reaction from TB or HTB by the experiment in which rabbits were given CTB intravenously.

The fact that substitution of an alkyl for a hydrogen on the N'-nitrogen inhibits hydrolysis favors the adjacent carbonyl carbon as the primary focus of hydroxide ion attack. b) The log k-pH profiles of N, N'-dimethyl-N-nitrosourea and 1, 6-dimethyl-1, 6-dinitrosobiurea show a deviation in the linearity of the alkaline branch which can be attributed to a kinetic pKa' where these compounds may exist as anions at higher pH values and thus be more resistant to hydroxide ion attack. c) The gas chromatographically analyzed alcohol products of alkaline degradation of N-alkyl-N'-nitrosourease are various in several cases and thus clearly implicate a potentiallu rearranging carbonium ion intermediate in the alkaline solvolyses of these compounds. The N-n-butyl compound gives a mixture of n-butyl-alcohol in 45% yield, and secondary butyl alcohol in 24% yield for pH values greater than 7.0. The fact that the N-isobutyl compound yields t-butyl alcohol (76%), sec-butyl alcohol (22%)and isobutyl alcohol (18%) also implicates a methyl shift. The N-alkyl-and N-benzyl-compounds yield only the corresponding alcohols.

The comparative absorption, metabolism, and excretion of SF-837 substance, a new macrolide antibiotic, was studied in rat, dog and man. Blood, urine and bile analysis were performed on these animals collected at several times after either oral ingestion or intravenous administration of a dose. SF-837 was found to be rapidly absorbed in rats and once in the body, was metabolized to M1 substance and M2 substance in rats, dogs and men. By densitometric analysis of thin-layer chromatograms, the urinary antimicrobial activities were analyzed falling in with 2.0%of unchanged SF-837, 18.0% of M1 and 1.7%of M2, and the biliary were analyzed falling in with 0.02% of unchanged SF-837, 5.8% of M1 and 47.3% of M2, within 24 hours after intravenous administration of SF-837 (50 mg/kg). Namely the main metabolite in the urine was M1 substance and that in the bile was M2 substance. The antimicrobial activity in the blood was derived mostly from M1 substance, not only by intravenous administration but also oral in rats. Similar results were obtained also from dogs and men. These results inficated that SF-837 was metabolised mainly to M1 substance and then M2 substance in rats, dogs and men.
