Anti-ulcer agent, Cetraxate hydrochloride (Neuer), prevents subcellular redistribution of lysosomal enzyme in caerulein-induced pancreatitis in the rat
J Int Med Res 1994 Mar-Apr;22(2):107-12.PMID:8020637DOI:10.1177/030006059402200207.
The protective effect of an anti-ulcer agent, Cetraxate hydrochloride [4-(2-carboxyethyl)phenyltrans-4-amino- methylcyclohexanecarboxylate hydrochloride], on the exocrine pancreas in caerulein-induced pancreatitis of rats was investigated. Hyperamylasaemia, pancreatic oedema and activation of trypsinogen in the pancreatic tissue, as well as subcellular redistribution of the lysosomal enzyme, cathepsin B, from the lysosomal fraction to the zymogen fraction, were prevented by infusion of 20 mg/kg.h cetraxate for 2 h before caerulein infusion and throughout the 3.5 h of caerulein infusion (5 micrograms/kg.h). The results indicate that cetraxate plays its protective roles against pancreatitis by inhibiting the redistribution of lysosomal enzyme and by activation of trypsinogen; such activities may be clinically useful in preventing pancreatic injuries, particularly in patients with chronic pancreatitis.
[The synthesis of 4'-(2-carboxyethyl)phenyl trans-4-aminomethyl cyclohexane carboxylate hydrochloride (Cetraxate hydrochloride) by means of enzymatic debenzylation]
Yakugaku Zasshi 1989 Mar;109(3):157-62.PMID:2754616DOI:10.1248/yakushi1947.109.3_157.
Cetraxate hydrochloride (1) (antiulcer agent) has been industrially produced by the chemical protective method of p-hydroxy propionic acid derivatives. Screening of enzymes which quantitatively hydrolyzed cetraxate benzyl ester hydrochloride (2) into 1 was undertaken to establish a novel enzymatic method of production of 1. It was found that the enzyme activity for debenzylation of 2 is contained in cellulase enzymes originated from Aspergillus sp. Lower alkyl groups or phenyl groups of p-hydroxy propionic acid derivatives are likewise selectively hydrolyzed by the cellulase enzyme. This enzymatic synthetic method is very useful for the industrial preparation of 1.
Cetraxate raises levels of calcitonin gene-related peptide and substance P in human plasma
J Pharm Pharmacol 2004 Apr;56(4):557-61.PMID:15099451DOI:10.1211/0022357023169.
Cetraxate hydrochloride (cetraxate), an anti-ulcer drug, produces a dose-related increase in mucosal blood flow. Recently, it was found that capsaicin-sensitive afferent nerves play an important role in gastric mucosal defence. Capsaicin stimulates afferent nerves and enhances the release of calcitonin gene-related peptide (CGRP) and substance P in the stomach. We studied the effect of cetraxate on human plasma CGRP and substance P in healthy subjects. Cetraxate (800 mg) or placebo were orally administered to five healthy males. Blood samples were taken before, and at 20, 40, 60, 90, 120, 180 and 240 min after administration, followed by the extracting procedure, and submitted to a highly sensitive enzyme immunoassay system for CGRP and substance P. Single administration of cetraxate caused significant increases in plasma CGRP concentration at 60-120 min compared with placebo. Cetraxate significantly increased plasma substance P levels at 40-90 min compared with placebo. In this study, we hypothesized that cetraxate might indirectly stimulate capsaicin-sensitive afferent nerves and increase mucosal blood flow, and that this may be a key mechanism underlying its gastroprotective action.
Enzymatic preparation of D-beta-acetylthioisobutyric acid and Cetraxate hydrochloride using a stereo- and/or regioselective hydrolase, 3,4-dihydrocoumarin hydrolase from Acinetobacter calcoaceticus
Appl Microbiol Biotechnol 2002 Nov;60(3):288-92.PMID:12436309DOI:10.1007/s00253-002-1116-3.
3,4-Dihydrocoumarin hydrolase (DCH) from Acinetobacter calcoaceticus F46, which was previously found on screening for aromatic lactone-hydrolyzing enzymes, catalyzes the hydrolysis of several linear esters. The substrate specificity of the enzyme toward linear esters was quite characteristic, i.e., (1) it was specific toward methyl esters, (2) it recognized the configuration at the 2-position, and (3) it hydrolyzed diesters to monoesters. DCH hydrolyzed the methyl esters of beta-acetylthioisobutyrate and cetraxate. The products of these reactions were identified as D-beta-acetylthioisobutyrate and cetraxate, respectively, i.e., the hydrolysis reactions catalyzed by DCH were stereo- and/or regioselective. With recombinant Escherichia coli cells expressing the DCH gene as a catalyst, stereospecific hydrolysis of methyl beta-acetylthioisobutyrate and regioselective hydrolysis of methyl cetraxate proceeded efficiently.
Inhibitory effect of prolonged oral administration of Cetraxate hydrochloride on experimentally-induced intestinal metaplasia in Wistar rats
Arzneimittelforschung 1987 Sep;37(9):1045-8.PMID:3435599doi
The effect of Cetraxate hydrochloride (Neuer) on the induction of intestinal metaplasia by intragastric instillation of 5% NaOH solution was investigated in Wistar rats. Oral administration of cetraxate, beginning 2 days after NaOH treatment, resulted in a significant increase in antral mucosal blood flow and a significant reduction in the incidence and amount of intestinal metaplasia in experimental week 25, but no significant changes in basal acid secretion or antral mucosal pH. On histological examination, goblet cell metaplasia were frequently seen. These results show that the increased gastric blood flow produced by Cetraxate hydrochloride may be associated with the suppression of induction of intestinal metaplasias.
