摘要:
A therapeutic and prophylactic agent for peptic ulcers which contains as an active ingredient a compound of the general formula (I): wherein R, represents hydrogen or =0; R 2 represents hydrogen or-OR 5 ; R 3 represents hydrogen or-OR 6 ; R 4 represents -OR 7 in the case of the absence of double bond, R 5 , R 6 and R 7 each represents hydrogen or an organic residue; X represents group (A): or group (B): wherein R 8 represents alkyl, and R 9 and R 10 each represents hydrogen or an organic residue; with the proviso that when X represents group (A), then R, and R 3 both represent hydrogen, R 2 represents -OR 5 , R 4 represents -OR 7 and the bond between the carbon atom to which X is attached and the carbon atom to which R 4 is attached is a single bond, and when X represents group (B), then R 1 represents =0, R 2 and R 4 both represent hydrogen, R 3 represents-OR 6 and the bond between the carbon atom to which X is attached and the carbon atom to which R 4 is attached is a double bond, or a pharmaceutically acceptable salt thereof, or a compound of the general formula (II): wherein R 11 represents hydrogen or an organic residue, and R 12 , R 13 and R 14 each represents an organic residue, or a pharmaceutically acceptable salt thereof. The compounds of the general formulae (I) and (II) can be derived from compounds contained in a hot water extract of cinnamon.
