- Gastric anti-secretory, anti-ulcer and cytoprotective properties of substituted (E)-4-phenyl- and heteroaryl-4-oxo-2-butenoic acids
-
A class of anti-secretory, anti-ulcer and cytoprotective agents, the substituted (E)-4-phenyl and heteroaryl-4-oxo-2-butenoic acids, is described.This chemical structure is not related to those of any known anti-cholinergic drugs, histamine H2-receptor antagonists or prostaglandins.Five compounds, 4-(2-methoxyphenyl)- 15, 4-(4-methoxyphenyl)- 22, 4-(3,4-dimethoxyphenyl)- 32, 4-(3,4,5-trimethoxyphenyl)- 40, and 4-(2-furanyl)-4-oxo-2-butenoic acid 44, have cytoprotective activity at a very low dose (0.6 mg/kg, p.o.) and anti-secretory and anti-ulcer activities at higher doses.One of these compounds, RU 38086 40, has been selected for clinical evaluation.Keywords - anti-ulcer agents / cytoprotective agents / (E)-4-phenyl- and heteroaryl-4-oxo-2-butenoic acids.
