| Originator | Zacopride hydrochloride,ZYF Pharm Chemical | | Uses | Anti-emetic; stimulant (peristaltic). | | Uses | Zacopride is a highly potent SR-3 antagonist and SR-4 agonist. 5-HT3 receptor antagonist. Activates IK1 channel. | | Definition | ChEBI: 4-amino-N-(1-azabicyclo[2.2.2]octan-3-yl)-5-chloro-2-methoxybenzamide is a member of benzamides. | | Manufacturing Process | 4-Amino-N-(1-azabicyclo[2.2.2]oct-3-yl)-5-chloro-2-methoxybenzamide,
fumarate [1:1]:
In a closed system equipped with an oil bubbler, 30 ml of tetrahydrofuran
were added to a mixture of 4-amino-5-chloro-2-methoxybenzoic acid, 2.02 g
(0.010 mole) and 1,1'-carbonyldiimidazole, 1.62 g (0.010 mole) with stirring.
When evolution of carbon dioxide ceased, nitrogen was bubbled through the
reaction mixture for 1 hr. A solution of 3-aminoquinuclidine, 1.26 g (0.010
mole) in 10 ml tetrahydrofuran was added dropwise to the stirred reaction
mixture and stirring at room temperature continued for 3 hrs. TLC analysis
(3% conc. ammonium hydroxide solution in methanol) showed some product
formation. The mixture was heated at reflux temperature for 18 hours and
then concentraded to an oil. TLC analysis showed the presence of the product,
imidazole and 3-aminoquinuclidine. The oil was dissolved in methylene
chloride (75 ml) and washed twice with 50 ml portions of aqueous sodium
bicarbonate solution. The methylene chloride layer was dried over anhydrous
magnesium sulfate and concentrated to yield 2.0 g (67%) of a glassy
amorphous solid, the free base of the title compound.
In another reaction on a 0.020 mole scale, 5.18 g (83.8%) of the product as
the free base was obtained.
The products were combined, dissolved in methanol (20 ml) and the solution
and treated with a solution of fumaric acid (2.73 g) in methanol (50 ml).
Absolute ether was added to precipitate the salt which was collected by
filtration and recrystallized from methanol-water (200:20) with isopropyl ether
added to the point of incipient cloudiness. The recrystallized salt (5.38 g)
melted at 223°-225°C.
4-Amino-N-(1-azabicyclo[2.2.2]oct-3-yl)-5-chloro-2-methoxybenzamide,
hydrochloride, hydrate (1:1:1):
To an isopropyl alcohol solution of the above free base of the title compound
is added in equal molar amount of 37% (conc.) hydrochloric acid. A salt is separated by addition of acetone followed by filtration which is recrystallized
from acetone-water to give the title compound, MP: 158°-160°C. | | Therapeutic Function | Antiemetic, Peristaltic stimulant | | Biological Activity | Highly potent 5-HT 3 receptor antagonist (K i = 0.38 nM) and 5-HT 4 receptor agonist (K i = 373 nM). Antiemetic and anxiolytic following systemic administration in vivo . |
