The absorption, disposition, metabolism, and excretion of acarbose (O-4,6-dideoxy-4-[[(1S, 4R, 5S, 6S)-4,5,6-trihydroxy-3- (hydroxymethyl)-2- cyclohexen-1-yl]amino]-a-D-glucopyranosyl- (1----4)-O-a-D-glucopyranosyl- (1----4) -D-glucopyranose, Bay g 5421) have been studied following a single administration of the 14C-labelled compound to rats and dogs via(More)
Isopropyl(2-methoxy-ethyl) 1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridinedicarboxylate (Bay e 9736, nimodipine) is a calcium antagonistic dihydropyridine derivative with a preferential effect on cerebral vessels. It dilates cerebral vessels in several species after intraarterial, intravenous, perlingual, and oral administration in low dosage. Its(More)
Neuro- and psychopharmacological effects of isopropyl-(2-methoxy-ethyl)-1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridinedicarboxylate (Bay e 9736, nimodipine) are described using a variety of methods measuring behavior under normal conditions, under the influence of psychotropic drugs, as well as under the influence of ischemia or hypoxia. It has(More)
14C-labelled (+/-) 3-isopropyl5-(2-methoxyethyl)1,4-dihydro-2,6-dimethyl-4- (3-nitrophenyl)-pyridine-3,5-dicarboxylate (nimodipine, Bay e 9736, Nimotop; CAS 66085-59-4) was administered orally to rat, dog, and monkey (each 5, 10, or 20 mg/kg) and intraduodenally to rat (5 mg/kg). Urine was collected over a period of 24 h (bile 6 h). Dog bile was obtained(More)
Inhibition of carbohydrate digestion by the alpha-glucosidase inhibitor acarbose (BAY g 5421)reduces carbohydrate-induced postprandial blood glucose increase and insulin secretion. As a consequence, in feeding experiments sucrose-induced hyperinsulinemia and hypertriglyceridemia in genetically obese (fa,fa) "Zucker" rats were dose-dependently reduced by(More)
The presence of angiotensinogen, the precursor of angiotensin II (ANG II), in brain tissue and in cerebrospinal fluid (CSF) allows stimulation of endogenous brain ANG II by renin. Passive avoidance tests were performed in female Wistar rats. The animals received an electrical shock after entering a black box on the first experimental day. Avoidance was(More)
The absorption, distribution, metabolism, and excretion of miglitol ((2R,3R,4R,5S)-1-(2-hydroxyethyl)-2-(hydroxymethyl)-3,4,5-piperidinet riol, CAS 72432-03-2, BAY m 1099) have been studied following single and repeated administration of non-labelled and radiolabelled (3H, 14C) drug to rats, dogs, and human volunteers via different routes of administration(More)
Acarbose (O-4,6-dideoxy-4-[[1S,4R,5S,6S)-4,5,6-trihydroxy-3- (hydroxymethyl)-2-cyclohexen-1-yl]amino]-alpha-D-glucopyranosyl- (1----4)-O-alpha-D-glucopyranosyl-(1----4)-D-glucopyranose, Bay g 5421) labelled with 14C was administered to male rats, pregnant and lactating rats as well as to female dogs with single intravenous or oral doses (2 or 4 mg.kg-1) and(More)
Attending to a conversation in a crowded scene requires selection of relevant information, while ignoring other distracting sensory input, such as speech signals from surrounding people. The neural mechanisms of how distracting stimuli influence the processing of attended speech are not well understood. In this high-density electroencephalography (EEG)(More)
