The distribution of 5-HT3 receptor sites was examined in rat brain by autoradiography using 3H-enantiomers of zacopride. The (S)-3H-isomer labelled high densities of binding sites in the hippocampus, amygdala and cortex. The (R)-3H-isomer labelled co

A 5-HT3 binding site, with high affinity for (S-)[3H]zacopride, was solubilized from rabbit small bowel muscularis membranes utilizing 0.5% sodium cholate and 400 mM (NH4)2SO4. Approximately 72% of the (S-)[3H]zacopride binding activity was recovered

In ferrets, the oral emetic activity of zacopride was compared with its R- and S-enantiomers. Increasing doses of 0.01, 0.1, 1.0, 10.0 and 31.6 mg/kg of zacopride or its 2 enantiomers were each administered at hourly intervals to separate groups of a

Zacopride administered orally was more emetic in fed than in fasted ferrets. The emetic activity of zacopride (0.1 mg/kg p.o.) was inhibited (100%) by 0.1 mg/kg i.p. of zacopride and 1 mg/kg i.p. of ICS 205–930. Haloperidol (3.16 mg/kg i.p.) and pr

[3H]Zacopride exhibits high affinity (Kd less than or equal to 1 nM) for 5-HT3 binding sites (inhibited by ICS 205-930) in rabbit intestinal muscularis and vagus nerve, human jejunum, rat intestinal muscularis and rat brain cortex. Its binding was in

The glutaminase activity of glutamine-dependent carbamyl phosphate synthetase (Escherichia coli) and that of the separated light subunit of this enzyme, as well as the glutaminedependent synthetase activity catalyzed by the native enzyme, are inactiv

Adenylate cyclase from rat kidney membranes solubilized with Lubrol-PX, was resolved into calmodulin-insensitive and calmodulin-sensitive forms using DEAE-Sephacel and calmodulin-Sepharose affinity chromatography. The major fraction, 90% of the activ

The monomer of glutamine-dependent carbamyl phosphate synthetase can be reversibly dissociated to a heavy (mol wt ∼130,000) and a light (mol wt ∼42,000) subunit by treatment with 1 m potassium thiocyanate. The separated heavy subunit can catalyze

Carbamyl phosphate synthetase from Escherichia coli, which is composed of a light and a heavy subunit, is inhibited with respect to its glutamine-dependent reactions by treatment with l-2-amino-4-oxo-5-chloro[5-14C]pentanoic acid. This glutamine anal

Glutamine-dependent carbamylphosphate synthetase ( Escherichia coli ) is composed of a heavy subunit (molecular weight about 130,000) and a light subunit (molecular weight about 42,000), which can be separated with retention of catalytic activities.
