Claims
- 1. A naphthyloxyacetic acid derivative of the general formula (I) wherein A is (C1-4 alkylene)-COOR1 in which R1 is hydrogen or C1-4 alkyl, E is (i) single bond or (ii) C1-6 alkylene; G is —NR4— in which, R4 is hydrogen or C1-4 alkyl; L is (i) C1-6 alkylene, (ii) —(CH2)m—CH═CH—(CH2)n— in which m is 0 or an integer of 1-3, n is 0 or an integer of 1-3 or (iii) —(CH2)x—CH(OH)—(CH2)y— in which x is an integer of 1-3, y is 0 or an integer of 1-3; M is in which each phenyl group may be substituted by 1-3 of C1-4 alkyl, C1-4 alkoxy, halogen, nitro or trifluoromethyl;with the proviso that,(1) when n in L is 0, M is in which each phenyl group may be substituted by 1-3 of C1 -4 alkyl, C1-4 alkoxy, halogen, nitro or trifluoromethyl,(2) when y in L is 0, M is in which each phenyl group may be substituted by 1-3 of C1-4 alkyl, C1-4 alkoxy, halogen, nitro or trifluoromethyl,in which R1 is the same meaning as defined above,or non-toxic salt thereof, non-toxic acid addition salt thereof or their hydrate.
- 2. A compound according to claim 1, wherein L is —(CH2)m—CH═CH—(CH2)n— or —(CH2)x—CH(OH)—(CH2)y—.
- 3. A compound according to claim 1, which is 2-{5-[2-(2RS-hydroxy-3-phenoxypropylamino)ethyl]-1-naphthyloxy}acetic acid.
- 4. A pharmaceutical composition which comprises a carrier and an effective amount of naphthyloxyacetic acid derivative of the formula (I) depicted in claim 1, non-toxic salt thereof, non-toxic acid addition salt thereof or their hydrate.
- 5. A prostaglandin E2 antagonist or agonist which comprises a naphthyloxyacetic acid derivative of the formula (I) depicted in claim 1, non-toxic salt thereof, non-toxic acid addition salt thereof or their hydrate.
- 6. 1-[2-(5-hydroxy-1-naphthyl)ethylamino]-3-phenoxy-2RS-propanol.
