Phenoxypropylamines: Synthesis and Antiulcer Evaluation

Phenoxypropylamines: synthesis and antiulcer evaluation.

We have synthesized a number of phenoxypropylamines from N-{3-[3-(1-piperidinylmethyl)phenoxy]propyl}chloroacetamide (3). All the products have been characterized by elemental analysis, (1)H-NMR and MS. The biological activity effects of the title compounds were examined. From the biological activity results, we found that two of themshowed significant gastric acid antisecretory activity.

Synthesis, characterization and antiulcer study of pH-sensitive microspheres

Omeprazole, a proton-pump inhibitor used in peptic ulcers, gastro-esophageal-reflux disorder, Zollinger-Ellison syndrome and in H. pylori infections. The omeprazole is unstable at acidic pH, undergoes degradation in stomach. To prevent the degradation in stomach, dosage forms are supplied as enteric-coated tablets or granules encapsulated in gelatin capsules. The efficiency of such dosage forms...

Synthesis and antiulcer activity evaluation of conjugates of amino acids with N-aroyl- N, N'-dicyclohexyl urea

Amino acids are safe molecules with variable efficacy against ulceration. Considering the good antioxidant potential of N-aroyl- N, N'-dicyclohexyl urea and antiulcer activities of amino acids, a series of amino acid conjugates of N-aroyl- N, N'-dicyclohexyl urea was synthesized and the effect against ulceration in albino rats induced by pyloric ligation was screened. All these compounds were f...

Coden: Ijpnl6 Evaluation of Antiulcer Activity of Plant Chrozophora Plicata

The herbal medicines derived from various plants extracts are being increasingly utilized to treat a wide variety of clinical diseases 1 . Besides their action as gastroprotectives, flavonoids also act in healing of gastric ulcers 2 . The study was designed to investigate the anti-ulcer effect of chloroform extract of Chrozophora plicata leaves (600mg/kg) against experimentally induced ulcer mo...
