2 new 4-trifluoromethylimidazole derivatives were found which lowered mean arterial pressure in renal and spontaneously hypertensive (SH) rats by the oral route. In SH rats, compounds A and B were 0.1 and 0.3 times, respectively, as potent as hydralazine. No tolerance development was observed in SH rats with either compound over a 1-week period. In anesthetized dogs, both compounds lowered arterial pressure and peripheral vascular resistance but increased cardiac output. By intraarterial administration, both compounds increased femoral arterial blood flow. These findings represent discovery of a new class of vasodilator durgs. 相似文献

Zusammenfassung 3-[4-(p-Fluorphenyl)-1,2,3,6-te-trahydro-1-pyridyl]-1-[1-(2-hydroxyaethyl)-5-methyl-4-pyrazolyl]-1-propanon (I, CIBA 4416/B-Go) senkt bei normotonischen und hypertonischen Tieren den Blutdruck. Die Drucksenkung kann hauptsächlich auf die periphere Vasodilatation sowie auf die Vasomotorenzentren bezogen werden. Ausserdem wirkt CIBA 4416/B-Go adrenolytisch.

Summary The synthesis and antischistosome properties of 5-(hydroxyimino)-4-methoxy-2-(pivaloylimino)thiazolidine-3-acetamide (1) are described. The compound was prepared by reduction of the nitrothiazoline (2) with stannous chloride in methanol, and represents the first example of a reduced nitroheterocyclic compound showing potent schistosomicidal properties. The possible relationship of compounds such as1 to the as yet unidentified reduced active but toxic entities formed in vivo from nitroheterocyclics like metronidazole is discussed.Acknowledgments. The authors are grateful to Dr A. J. Everett and his staff for the physical chemistry measurements, and to Mr G. Dickerson for the antischistosome testing. 相似文献

Summary The biological properties of a novel compound 353C with high activity againstTrypanosoma cruzi, are described. The compound was about 10 times and 20 times more effective than either benznidazole or nifurtimox respectively, in producing radical cure in mice. 353C had a long half-life and showed anti-trypanosomal properties when given to mice at weekly intervals. 相似文献

In the Dog, 3-(2-hydroxy-3 isopropylamino-proxy)-2-phenyl-1-isoindolinone (RS, SR) possesses an anti-arrhythmic activity similar to that of quinidine but at dose levels 2 to 6 times lower than in the case of the latter compound. Furthermore, in contrast to quinidine, at the dose levels where the antiarrhythmic activity is well observed, the compound is devoid of hypotensive activity and of depressive action on cardiac contractility. The first clinical studies of this compound have shown its usefulness in the treatment of ventricular and supraventricular arrhythmias. 相似文献

Zusammenfassung 1-(5-Methyl-1-phenyl-4-pyrazolyl)-3-[4-(o-tolyl)-piperazinyl]-1-propanone (I; CIBA 1002-Go), senkt an normotonischen und hypertonischen Tieren den Blutdruck. Die Drucksenkung kann auf eine periphere Vasodilatation und eine Hemmung hypothalamischer oder medullärer Vasomotorenzentren bezogen werden. Ausserdem wirkt CIBA 1002-Go adrenolytisch.

Zusammenfassung Centpyraquin (3-(-p-fluorobenzyl propyl) 2,3,4,4a,5,6-hexahydro-1(H)-pyrazino (1,2-a) quinoline hydrochloride) zeigte hypotensive Aktivität bei narkotisierten wie auch bei wachen Katzen. Es senkt auch den Blutdruck bei Ratten mit nephrogenem Hochdurck. Die Hypotension scheint auf einem peripheren Mechanismus zu beruhen.

Imazalil is a new fungicide effective against Penicillium molds on fruits after harvest. This compound inhibits ergosterol biosynthesis in mycelia of Penicillium expansum. The accumulation of 24--methylenedithydrolanosterol, obtusifoliol and 14 alpha-methyl-delta 8, 24(28)-ergostadienol in treated fungi suggests that imazalil blocks sterol C--14 demethylation. 相似文献

Summary Microsomes from livers of scorbutic guineapigs showed a reduced rate of acetanilide hydroxylation. The response of scorbutic liver microsomes to the inhibitor Metyrapone (2-methyl-1,2 di (3-pyridyl)propan-1-one) was different from that of liver microsomes from non-scorbutic guinea-pigs. 相似文献

Summary 7-Chloro-3-(4-methyl-1-piperazinyl)-4H-1,2,4-benzothiadiazine-1,1-dioxide (DU-717) is a new compound having sustained antihypertensive activity in a similar manner to that of hydrochlorothiazide. However, this compound shows neither diuretic nor hyperglycemic effect, being different from those of hydrochlorothiazide or diazoxide. 相似文献

Summary dl-Erythro-1-phenyl-2-(o-chlorophenyl)-2-[4-(p-methoxybenzyl)-1-piperazinyl] ethanol dihydrochloride showed orally a definite analgesic activity, without producing the significant morphine-like physical dependence liability, and its analgesic potency was about a half that of codeine and far superior to aminopyrine in experimental animals. 相似文献

Microsomes from livers of scorbutic guinea-pigs showed a reduced rate of acetanilide hydroxylation. The response of "scorbutic" liver microsomes to the inhibitor Metyrapone (2-methyl-1,2 di (3-pyridyl) propan-1-one) was different from that of liver microsomes from non-scorbutic guinea-pigs. 相似文献
