Abstract
A compound of the formula: ##STR1## wherein X.sup.1 is a free or an esterified carboxyl group, or a group of the formula: ##STR2## (R.sup.a and R.sup.b are each independently a hydrogen atom, a C.sub.1 -C.sub.4 alkyl group, a C.sub.3 -C.sub.7 cycloalkyl group, a benzyl group, a phenyl group, a phenyl group substituted with a halogen atom or a C.sub.1 -C.sub.4 alkyl group, or, when taken together with the adjacent nitrogen atom to which they are attached, they represent a 5 to 7 membered saturated heterocyclic group, Y.sup.1 is a group of the formula: ##STR3## (R.sup.6 is a hydrogen atom or C.sub.1 -C.sub.4 alkyl group), ##STR4## (R.sup.6 is as defined above), ##STR5## R.sup.1 is a hydrogen atom, a hydroxyl group or a protected hydroxyl group, R.sup.2 is a hydrogen atom or R.sup.1 and R.sup.2, when taken together, mean a shingle linkage to from a double bond between the carbon atoms which they are linked, R.sup.3 is a hydroxyl group or a protected hydroxyl group, R.sup.4 is a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group, R.sup.5 is a hydrogen atom, a C.sub.1 -C.sub.12 alkyl group, a C.sub.2 -C.sub.12 alkenyl group, a C.sub.2 -C.sub.12 alkynyl group, a C.sub.3 -C.sub.10 cycloalkyl group, a C.sub.4 -C.sub.10 cycloalkenyl group, a hydroxy C.sub.1 -C.sub.12 alkyl group, a C.sub.3 -C.sub.10 heterocyclic group, a phenyl group optionally substituted with a halogen atom; a hydroxyl group, a C.sub.1 -C.sub.4 alkyl group, a trifluoromethyl group, or a C.sub.1 -C.sub.4 alkyl group or a formula: A-B (A is a C.sub.1 -C.sub.7 alkylene chain and B is a C.sub.3 -C.sub.10 cycloalkyl group, a C.sub.4 -C.sub.10 cycloalkenyl group, a C.sub.1 -C.sub.12 alkoxy group, a C.sub.3 -C.sub.10 cycloalkoxy group, a C.sub.4 -C.sub.10 cycloalkenyloxy group, a C.sub.3 -C.sub.10 heterocyclic group, or a phenyl or phenoxy group optionally substituted with a halogen atom, a hydroxy group, a C.sub.1 -C.sub.4 alkyl group, a trifluoromethyl group or a C.sub.1 -C.sub.4 alkoxy group); or a non-toxic pharmaceutically acceptable salt thereof. Said compound have strong anti-ulcerous action or antithrombotic action, and are useful in treatment of ulcer or thrombosis.
