8. Other Information
8.0 靶点

IC50: 81 μM (ACE)

8.1 体外研究

Kinetic analyses demonstrate that enalapril inhibits the uptake of GlySar in a competitive manner (K i approximately 6 mM). Fosinopril and Zofenopril have the greatest inhibitory potency (IC 50 values of 55 and 81μM, respectively) while the other ACE inhibitors exhibit low-affinity interactions with the renal peptide transporter.

8.2 体内研究

Zofenopril, a sulphydrylic compound, at doses higher than 70 mg/kg i.p. produces significant protection (i.e. at 70 mg/kg, P=0.044, F=2.17, d.f.=18; at higher concentration P<0.05) against the tonic phase of the audiogenic seizure response. Pretreatment with Zofenopril (15 mg/kg, i.p.) is able to produce a consistent shift to the left of the dose-response curves and a significant reduction of ED 50 values against clonus of some AEDs with the exceptions of diazepam, felbamate, phenobarbital and phenytoin compare with concurrent groups, suggesting an increase in anticonvulsant activity.

8.4 Uses
Zofenopril-d5 is intended for use as an internal standard for the quantification of Zofenopril by GC- or LC-mass spectrometry.
8.5 Definition
ChEBI: A proline derivative that is 4-(phenylsulfanyl)-L-proline in which the amine proton is replaced by a (2S)-3-(benzoylsulfanyl)-2-methylpropanoyl group. A prodrug for zofenoprilat.
8.6 Manufacturing Process
9.9 g (0.031 mole) of cis-4-phenylthio-L-proline is suspended in 100 ml of water (pH 5.6) and the pH is adjusted to 10.2 by the addition of about 20 ml of 10% sodium bicarbonate to provide a clear solution. The pH is then adjusted to 9.5 by the addition of about 4.5 ml of concentrated HCl. The solution is kept at 30°C while 8.1 g (0.033 mole) of (D)-3-(benzoylthio)-2- methylpropanoic acid chloride in 30 ml of toluene is added simultaneously with 100 ml of 10% sodium bicarbonate to keep the pH at 9.3. After about 1/4 of the acid chloride is added, a slimy precipitate begins to form which persists throughout the reaction. After stirring the reaction mixture at pH 9.3 for 2.5 h, it is made strongly acidic by adding 20% HCl in the presence of ethyl acetate. The aqueous layer is extracted twice with 350 ml portions of ethyl acetate and the combined organic layers are washed with 300 ml of saturated brine and dried (MgSO 4 ). The solvent is removed to yield 11.8 g of foamy solid cis-1-[D-3-(benzoylthyo)-2-methyl-1-oxopropyl]-4-(phenylthio)-L-proline hydrochloride.
To a solution of this cis-1-[D-3-(benzoylthyo)-2-methyl-1-oxopropyl]-4- (phenylthio)-L-proline hydrochloride 11.8 g (0.027 mole) in 70 ml of acetonitrile there is added about 6.0 g of dicyclohexylamine in 25 ml of ether. A white crystalline precipitate forms immediately. After standing overnight in the cold room, the solid is filtered and washed with ether to yield (cis)-1-[D- 3-(benzoylthio)-2-methyl-1-oxopropyl]-4-(phenylthio)-L-proline, dicyclohexylamine salt (1:1).
he slightly moist (cis)-1-[D-3-(benzoylthio)-2-methyl-1-oxopropyl]-4- (phenylthio)-L-proline dicyclohexylamine salt is stirred for 2.5 h in a mixture of 300 ml of ethyl acetate and 200 ml of 10% potassium bisulfate. Two clear layers form. The aqueous layer is extracted with two 200 ml portions of ethyl acetate and the combined organic layers are dried (MgSO 4 ). The solvent is removed to yield 10.1 g of foamy solid (cis)-1-[D-3-(benzoylthio)-2-methyl-1- oxopropyl]-4-(phenylthio)-L-proline; melting point 42-44°C.
In practice it is usually used as calcium salt (2:1).

Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS; and VASODILATOR AGENTS. (See all compounds classified as Antihypertensive Agents.)|A class of drugs whose main indications are the treatment of hypertension and heart failure. They exert their hemodynamic effect mainly by inhibiting the renin-angiotensin system. They also modulate sympathetic nervous system activity and increase prostaglandin synthesis. They cause mainly vasodilation and mild natriuresis without affecting heart rate and contractility. (See all compounds classified as Angiotensin-Converting Enzyme Inhibitors.)
