ジャーナル フリーIn order to examine the efficacy of helminthics, some resorcinol derivatives were synthesized.
(1) Hexylresorcinol dicarbamate, m.p. 181-182°.
(2) Hexylresorcinol dicarbethoxylate, oil.
(3) 6-Chloro-4-alkylresorcinols (where alkyl was: ethyl, propyl, butyl, amyl, isoamyl, hexyl, heptyl, octyl).
All of these chlorine derivatives, except the ethyl derivative, combined one molecule of water of crystallization to form stable crystals. As to the anthelmintic power of those derivatives, those with 5-8 carbons in their alkyl radical were the strongest, while irritation of mucous membrane was weaker that of hexylresorcinol in those with alkyl group of 6-8 carbons.
(4) 2, 6-Dichloro-4-alkylresorcinols (alkyl: hexyl, isoamyl, amyl) showed neither irritant properties nor anthelmintic action.
(5) 6-Bromo-4-alkylresorcinols had very weak anthelmintic action.抄録全体を表示PDF形式でダウンロード (879K) -

ジャーナル フリーFormylacetone-anil and guanidine were boiled in alcohol on a water bath for one hour in the presence of sodium ethoxide, and 2-amino-4-methylpyrimidine was obtained in a 70% yield. Sulfamerazine was synthesized by the same method in a 15% yield using sulfaguanidine. Sulfamerazine is also obtained by fusing formylacetone-anil and sulfaguanidine in the presence of NaOH in a yield of 60%. 2-Aminopyrimidine was obtained by boiling for 4hrs. malonedialdehyde-dianil and guanidine in alcohol in the presence of sodium ethoxide, in a yield of about 30%. In this reaction, sulfadiazine was not obtained by the use of sulfaguanidine.抄録全体を表示PDF形式でダウンロード (249K) -

ジャーナル フリーAn attempt was made to apply the van Slyke's method used in the quantitative determination of amino acids for heterocyclic amino compounds. 2-Aminopyridine derivatives were able to be determined and were not affected by the presence of other substituents. Diazonium compound of 3-aminopyridine was stable but its stability was influenced by both temperature and other substituents. 2-Aminothiazole derivatives can also be determined, but about twice the theoretical amount of gas is produced from 2-amino-4-methylthiazole. Hydrogen in 5-position was assumed to take part in this reaction, since 2-amino-4-methyl-5-ethanol-thiazole gave the same result as for 2-aminothiazole. It was found difficult to liberate nitrogen gas from guanidine by van Slyke's method, but when 2-aminopyrimidine derivatives were produced by pyrimidine nucleus formation, nitrogen gas was liberated quantitatively. Diazonium compound of 4-aminopyrimidine derivatives was stable.抄録全体を表示PDF形式でダウンロード (549K) -

ジャーナル フリーOf the Chinese drug prescriptions resistered in the National Formulary (Japan), antibacterial activities were examined of 51 prescriptions, used in bacterial diseases, of 11 other prescriptions, and, futher, of 35 kinds of crude drugs composing their effective principles, with following results.
(1) Almost all Chinese drug prescriptions applied in bacterial diseases possessed growth inhibition against Staphylococcus and B. coli, although the degree of effectiveness varied more or less.
(2) The antibacterial crude drugs have increased growth prohibiting actions when used in prescriptions and in a concentrated state in case of prescriptions, than when used only by itself.
(3) Both prescriptions and crude drugs generally possessed strong growth inhibiting activities against Staphylococcus but a weak against B. coli.抄録全体を表示PDF形式でダウンロード (897K) -

ジャーナル フリーThe influences of some drugs upon M. tuberculosis and the measurement of the amount of oxygen consumption, measured by the Warburg's manometer, and at the same time, the growth inhibiting activities using Kirchner's culture medium, in which 10% of serum was added, were compared. 31 compounds were tested; i.e. 10 of resorcinol compounds; 7 of lichen, substances 6 of coumarin compounds, 8 of plant components and synthesized products. There are many types in consuming oxygen, and among them usnic acid, monochlorocyclohexylresorcinol, showed the strongest inhibiting action to oxygen consumption. Usnic acid and p-aminosalicylic acid were the strongest in inhibiting growth, 2, 4-dihydroxy-3-chloro-5-n-amylbenzaldehyde, 2, 4-dihydroxy-3-chloro-5-n-hexylbenzaldehyde followed these products. It was shown that the inhibiting action to oxygen consumption and the growth inhibiting activities were not always parallel.抄録全体を表示PDF形式でダウンロード (551K) -

ジャーナル フリーWe obtained o-thiocresol the final product, by the electrolytic reduction of o-toluenesulfonchloride in alcoholic sulphuric acid solution in which lead pole is used as cathode, and at the same time, o, o′-ditolyldisulfide, o, o′-ditolydisulfoxide, o-toluene-sulfonic acid were obtained as the intermediate products. These products conincide with the ones which we obtained in the electorlytic reduction of p-toluenesulfonyl choloride. But there was a difference of the current efficiency, in the reduction between p-compound and o-compound. As to o-compound, sulfinic acid and disulfoxide were reduced in good current efficiency but that of disulfide was not so good. Differing from the case of p-compound, the production of -disulfoxide followed that of sulfinic acid in case of o-compound. These results showed that the reductive reaction might be proceeded in a different mechanism in the cases of o-compound and p-compound respectively.抄録全体を表示PDF形式でダウンロード (656K) -

Glass electrodes were also experimentally manufactured from soft, hard and McInnes glasses into diaphragm-type electrodes. As a result of a determination of the relationship between E. M. F. and pH, McInnes glass was found to be the most suitable. pH of blood, saliva and urine was determined using this electrode.抄録全体を表示PDF形式でダウンロード (680K) -
