Zusammenfassung Die Synthese von (—)-1(7)-Tetrahydrocannabinol (THC) auf (—)-1(6) wird beschrieben. Das Hauptprodukt der oxidativen Zerstörung von (—)-1-THC ist Cannabinol. Beschleunigte Versuche der Luftoxidation von (—)-1-THC und (—)-1(6)-THC haben gezeigt, dass das letztere beständiger ist. Dieser Unterschied kann mit der Reaktivität des C3-benzylisch-allylischen Wasserstoffes in (—)-1-THC erklärt werden. 相似文献

Summary Following topical application of14C-labeled 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU, carmustine) to the skin of mice radioactivity was found in all viscera and tissues examined. Exclusive of the gut, highest values were recorded for the liver, kidney and lung.Supported by Public Health Service, grant CA 14825, from the National Cancer Institute, National Institutes of Health, Department of Health, Education and Welfare. 相似文献

Zusammenfassung Es wird gezeigt, dass bei männlichen Wistar-Ratten im 3-Wochen-Diätexperiment mit Zusatz von 0,3% 2-Methyl-2-(p-1,2,3,4-Tetrahydro-1-naphthylphenoxy)-Propionsäure (Su-13437) die Oxydation von 26-14C-Cholesterin zu14CO2 durch Lebermitochondrien (bezogen auf mg/N) ähnlich wie bei den Kontrollen war. Bei den Versuchstieren war jedoch bei Abwesenheit von Cytosol im System die Oxydation durch Lebermitochondrien erhöht.

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

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 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 drugs.Deceased, May 31, 1978. 相似文献

Wide variations have been found in the responsiveness to (1-24)ACTH of Mongolian gerbil adrenal glands superfused in vitro. These variations were not correlated to corticosteroid plasma levels or to adrenal weights. In contrast, (1-24)ACTH-stimulated secretion greatly depended on basal in vitro secretion (quarters: r = 0.97, p less than 0.01; slices: r = 0.90, p less than 0.001) indicating that the fine adjustment of basal corticosteroidogenesis forms an important part of the regulatory mechanisms modulating (1-24)ACTH-stimulated corticosteroid secretion in vitro. 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
