JOURNAL FREE ACCESSSeveral bisquarternary ammonium salts were synthesized and tested as to their antitumor activity. However, none of them exhibited any effective activity. Additionally, alkylation of nucleophiles with quarternary ammonium salts, dimethylaminomethyl p-tolyl ether methiodide and ethylene bis (N, N-diethyl-N-methylammonium iodide), was examined. Dimethylaminomethyl p-tolyl ether methiodide reacted successfully with nucleophiles, such as amine, thiol and alcohol, to give the expected compounds in which p-tolyloxymethyl group was introduced to the nucleophilic compounds. On the other hand, ethylene his (N, N-diethyl-N-methylammonium iodide) reacted with thiophenol and diethyl malonate to give the methylated compounds, methyl phenyl sulfide and diethyl malonate respectively.View full abstractDownload PDF (1059K) -

JOURNAL FREE ACCESS17β-Benzoyloxy-2α-hydroxy-5β-androstane (XIb), the key intermediate for the transannular cyclization reaction from 2C to 9C in the 5β-androstane system, was synthesized from testosterone (III) in six steps and in the overall yield of 17.6% via the intermediacy of 2α-hydroxy-4-en-3-oxo system (VII). The stereochemistry of the epoxidation of the 4-en-3-oao system (III) with alkaline hydrogen peroxide was established, the reaction favoring the formation of the 4β, 5-epoxide (IVb) to the formation of the 4α, 5-isomer (IVa) in the relative ratio of 5:1. Meanwhile, oxidation of XIb with Jones reagent afforded the 2-oxo-5β system (XIIIb) which exhibits negative Cotton effect curves with much weaker intensity compared with that of positive Cotton effect curves exhibited by the 2-oxo-5α system (XIIIa).
Treatment of XIb with lead tetraacetate in benzene afforded 17β-benzoyloxy-2α, 9α-epoxy-5β-androstane (XVII). The 17β-acetoxy analogue (XIX) of the 2α, 9α-epoxide (XVII) was converted to the 9α, 11α-epoxide system (XXII) via the 9 (11)-eno intermediate (XXI). Reductive cleavage of XXII with lithium-ethylamine afforded the 2α, 9α, -17β-trihydroxy-5β-androstane (XXIII) which gave 2α, 17β-diacetate (XXIV).View full abstractDownload PDF (3102K) -

JOURNAL FREE ACCESSThe metabolites of clofexamide (2-(p-chlorophenoxy)-N-(2-diethylaminoethyl)-acetamide)(I) have been investigated in rat urine and feces. When rats were given a single 200mg/kg dose of clofexamide (I), thirteen metabolites were found in the urine and only unchanged clofexamide in the feces. Twelve metabolites were identified by their spectrometric data (infrared (IR), mass spectrum, ultraviolet (UV) and nuclear magnetic resonance (NMR) spectra) and by thin-layer chromatography (TLC). The following compounds were found to be present in the urine: unchanged clofexamide (I), 2-(p-chlorophenoxy)-N-(2-diethylaminoethyl) acetarnide N-oxide (II), 2-(p-chlorophenoxy)-N-(2-ethylaminoethyl) acetamide (III), 2-(p-chlorophenoxy)-N-(2-aminoethyl) acetamide (IV), p-chlorophenoxyacetic acid (V), p-chlorophenoxyaceturic acid (VI), 2-(4-chloro-3-hydroxyphenoxy)-N-(2-diethylaminoethyl) acetamide (VII), its glucuronide (VIII), 2-(4-chloro-2-hydroxyphenoxy)-N-(2-diethylaminoethyl) acetamide (IX), 2-(4-chloro-3-hydroxyphenoxy)-N-(2-ethylaminoethyl) acetamide (X), its glucuronide (XI) and 2-(4-chloro-2-hydroxyphenoxy)-N-(2-ethylaminoethyl) acetamide (XII).View full abstractDownload PDF (1671K) -

JOURNAL FREE ACCESSThe analgesic, anti-inflammatory and antipyretic activities of six aminotroponoidcompounds were investigated.
Analgesic activities of 5-aminotropolone (I) and 2-aminotropone (II) are found to be equipotent to that of aminopyrine.
All the test compounds do not inhibit the development of the erythema induced by ultraviolet irradiation, but I and II show the strong inhibition (70-80%) of the enhancement of capillary permeability induced by acetic acid.
Compounds, I and II produce marked hypothermia in mice, rats, and guinea-pigs, and I and II show the antipyretic activities as same as aminopyrine.
The acute toxic symptoms of most of the test compounds are generally the extremities ataxia and the respiratory paralysis.View full abstractDownload PDF (1328K) -

JOURNAL FREE ACCESSThe effects of benzylidene chromanones and its related compounds on coronary and femoral blood flow were examined in anesthetized dogs. They exhibited vasodilating activity in both vascular beds, but less active than that of papaverine. Intravenous administration of 3-(4'-β-diethylaminoethoxy)-benzylidene chromanone HCl (CDY-902) caused an increase in coronary blood flow as well as a transient hypotension and persistent negative chronotropic action. No significant effect of CDY-902 on myocardial oxygen consumption of the dog in situ was observed. On oxygen uptake of the rat heart slices CDY-902 elicited a decrease similar to papaverine. As the results were compared with those of papaverine, GTN and dipyridamole, CDY-902 appears to have a direct and nonselective effects on coronary vascular bed.View full abstractDownload PDF (957K) -

JOURNAL FREE ACCESS2-Substituted thiazolidines (IIIa-g) were prepared by the reaction of 2-alkylthiothiazolines (II) and active methylene compounds. The tetra-substituted double bonds of IIIa-g were resistant to catalytic hydrogenation. N-Halogenation of IIIb was effected by t-butylhypochlorite or bromine in methanol-chloroform. BF3-etherate treatment of IIIb in acetic anhydride gave three products, VI, VII and VIII. This new method of furoxane formation was also applicable to the conversion of ethyl nitroacetate to VI. The mechanisms of the formations of VI and VII are proposed briefly in Chart 4.View full abstractDownload PDF (851K) -

JOURNAL FREE ACCESSContinuous oral administration of sodium cyclamate (CHS-Na) to guinea pig caused the gradual increase of urinary excretion of cyclohexylamine (CHA) after a certain period. The amount of CHA excreted was not only different in individuals, but also dependent on each experiment. It was diminished when CHS-Na was administered orally with antibiotics or intraperitoneally. It was shown from the incubation experiments that apparent accumulation of CHA was observed by cecal contents or feces from the animal excreting CHA in urine by oral administration of CHS-Na, but not from that diminished the excretion by the above conditions. Any in vitro study using animal tissues failed to detect the accumulation of CHA. Consequently it may be probable to assume the participation of duct microflora in the conversion of CHS-Na to CHA in guinea pig.View full abstractDownload PDF (1025K) -

Also, the all valence-electronic structure, especially the hybridization state of the valence-atomic orbitals of the heteroatoms, was calculated using the extended Hiickel method in order to compare the electronic structures of the two possible spacial configurations with respect to the position of the proton attached to the nitrogen atom.View full abstractDownload PDF (884K) -

The methylene hydrogens of the compound (IV) was shown to have a nature of an active methylene group and to react with various electrophiles. The four position of the isoxazole ring of IV had also nucleophilic character, which was useful for obtaining a cyclohexane derivative.

It has been elucidated that the authors' previous proposal on the structures of zeorin (II*), hopane (III*), and isohopane (XXI*) should be abandoned and the final conclusion on the stereostructure of zeorin (II) in addition to its correlation with leucotylin (I) has been presented.

JOURNAL FREE ACCESSTransformation of chitosan in conc. H2SO4 was investigated. Neither reaction temperature (0, 10, and 30°) nor time (1-10 hr) affected the degree of sulfation of chitosan, but it was markedly influenced by temperature of the ether used to separate sulfated products. It was proved that depolymerization of chitosan, which had been observed to be extremely stable to conc. H2SO4, was influenced by the remaining N-acetyl content in chitosan. As expected, chitosan was greatly depolymerized by treatment with hydrated conc. H2SO4 (80 and 90% of sulfuric acid by weight), and sulfated in a lesser extent than that of conc. H2SO4.
A hydrolysis constant, K1 7.0×10-2 min-1, of the acid-labile sulfate in sulfated chitosan indicated a reliable formation of the N-sulfate bound to the amino group in sulfated chitosan.View full abstractDownload PDF (1020K) -

During the study on the Niementowski condensation of anthranilic acid with thiopicolinanilides, we also found that an anthranilate of 4 (3H)-quinazolinone is formed in the course of this reaction.
