Abstract
We proposed a novel compound having an activity of PGI.sub.2 receptor agonist. A phenoxyacetic acid derivative of the formula ##STR1## A is --C(R.sup.1).dbd.N.about.OR.sup.2, --CH(R)NH--OR.sup.2, --COE, --SO.sub.2 E, --CH.sub.2 --NR.sup.3 --Y, --Z -- NR.sup.3 --CONR.sup.4 R.sup.5, --CH.sub.2 --OR.sup.6, --CO.sub.2 R.sup.6, --CH.sub.2 --O.about.N.dbd.CR.sup.7 R.sup.8, --CH.sub.2 --O--NHCHR.sup.7 R.sup.8, substituted by imidazolyl(methyl), pyrazolylmethyl, oxazolyl(methyl), thioxazolyl, isoxazolyl, isothiazolyl, oxadiazolyl, triazolylmethyl; T is alkylene, alkenylene, etc.; D is --CO.sub.2 R.sup.10, --CONR.sup.11 R.sup.12 ; E is (substitution) amino, hydradino; Y is substituted (thio) carbonyl, substituted sulfonyl; Z is --CH.dbd.N--, --CH.sub.2 NR.sup.3 --; R.sup.1, R.sup.3, R.sup.10 -R.sup.13 is each H or alkyl, etc.; R.sup.2, R.sup.4 -R.sup.9 is each H, alkyl or alkyl substituted by phenyl or hetero ring, etc. and non-toxic salts thereof, non-toxic acid addition salts thereof, possess an agonistic on PGI.sub.2 receptor, so it is useful for prevention and/or treatment of thrombosis, arteriosclosis, ischemic heart diseases, gastric ulcer and hypertention.
