Abstract: A therapeutic and prophylactic agent for peptic ulcers which contains as an active ingredient a compound of the general formula (I): ##STR1## wherein R.sub.1 represents hydrogen or .dbd.O; R.sub.2 represents hydrogen or --OR.sub.5 ; R.sub.3 represents hydrogen or --OR.sub.5 ; R.sub.4 represents --OR.sub.7 in the case of the absence of double bond; R.sub.5, R.sub.6 and R.sub.7 each represents hydrogen or an organic residue;X represents group (A);.dbd.C.dbd.CH--COR.sub.8 (A)or group (B): ##STR2## wherein R.sub.8 represents alkyl, and R.sub.9 and R.sub.10 each represents hydrogen or an organic residue; with the proviso that when X represents group (A), then R.sub.1 and R.sub.3 both represent hydrogen, R.sub.2 represents --OR.sub.5, R.sub.4 represents OR.sub.7 and the bond between the carbon atom to which X is attached and the carbon atom to which R.sub.4 is attached is a single bond, and when X represents group (B), then R.sub.1 represents .dbd.O, R.sub.2 represents hydrogen, R.sub.3 represents --OR.sub.

Abstract: A cycloalkane derivative represented by the formula (I): ##STR1## wherein A, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, Z, and n are as defined in the specification. The compounds of formula (I) exhibit activities against peptic ulcers and are useful as therapeutic and prophylactic agents for peptic ulcers.
