Effects of KB-5492, 1-(3,4,5-trimethoxybenzyl)-4-((4-methoxyphenyl)oxycarbonylmethyl) p iperazine monofumarate monohydrate, on gastric lesions and gastric secretion in rats.
Effects of a newly synthesized compound, KB-5492, on gastric lesions and gastric secretion were studied in rats. Oral KB-5492 inhibited the lesions induced by HCl.ethanol, HCl.aspirin, water-immersion stress, indomethacin, histamine and prednisolone at 30-300 mg/kg. The ED50 values varied from about 35 to 98 mg/kg. KB-5492 had no effect on gastric acid secretion even at 300 mg/kg. KB-5492 appeared to have a much more potent protective effect than a known anti-ulcer drug, sofalcone, against acute gastric lesions.
