     FIELD OF TECHNOLOGY 
     This invention is related to the naphthyloxyacetic acid derivatives. More particularly, this invention is related to 
     (1) the naphthyloxyacetic acid derivatives of the formula (I)                           
     wherein all symbols are the same meaning as hereafter defined, or non-toxic salts thereof, acid addition salts thereof or their hydrates and 
     (2) a pharmaceutical composition (Prostaglandin E 2  (PGE 2 ) antagonists or agonists) which comprises them as an active ingredient. 
     BACKGROUND 
     PGE 2  has been known as metabolite in the arachidonate cascade. In addition, the recent progress in the molecule biological technology makes the existence of three PGE 2  receptors clear as shown in the following and have been making the relationship between each receptor and appearance of biological activity clear. For example, EP 1  receptor may cause contraction of the smooth muscle of digestive canal or bronchus etc. and promote the release of neurotransmitter. The representative activity of EP 2  receptor is relaxation of smooth muscle of bronchus or ileum etc. or vasodilatation and reduce of the blood pressure due to relaxation of vascular smooth muscle. As the activity of EP 3  receptor, uterine muscle contraction, suppression of gastric acid secretion, inhibition of reabsorption of water and ion by vasopressin in renes, inhibition of fat decomposition in fat tissue, inhibition of release of neurotransmitter and glucose-decomposition by gulcagon in liver cell etc. have been known. In addition, recently, the existence of fourth receptor is suggested. (Biochemistry Vol. 66, No. 3, pp. 218-231 (1994)). 
     Therefor, to antagonize PGE 2  receptor means to suppress the effects above mentioned, so such an activity is linked to inhibit diuretic, to inhibit hyperlipemia, to inhibit reduce of blood sugar, to inhibit uterine contraction, to have analgesic action, to inhibit digestive peristalsis, to induce sleep. Therefor, PGE 2  receptor antagonists are considered to be useful as anti-hyperlipemia, for the prevention of abortion, for analgesics, or as antidiarrheals or sleep inducer. 
     To agonize for PGE 2  receptor means to promote the effects above mentioned, so such an activity is linked to have diuretic, to promote hypedipemia, to promote reduce of blood sugar, to contractile uterine, to promote digestive peristalsis, to suppress gastric acid secretion or to reduce blood pressure. Therefor, PGE 2  receptor agonists are considered to be useful for diuretic, anti-diabetes, abortient, cathartics, antiulcer, anti-gastritis or antihypertensive. 
     In such a background, a lot of compounds which agonize or antagonize for PGE 2  receptors have been proposed.

     Method of Preparation for the Compounds of the Present Invention 
     In the compounds of the formula (I) of the present invention, the compounds of the formula (I-1)                           
     wherein all symbols are the same meaning as hereinbefore defined 
     may be prepared by the following methods (a)-(b). 
     (a) In the compounds of the formula (I-1) of the present invention, the compounds wherein L is —(CH 2 ) x —CH(OH)—(CH 2 ) y — or C1-6 alkylene, i.e., the compounds of the formula (I-1a)                           
     wherein L a  is —(CH 2 ) x —CH(OH)—(CH 2 ) y — or C1-6 alkylene, and the other symbols are the same meaning as hereinbefore defined 
     may be prepared from the compounds of the formula (II-a)                           
     wherein L aa  is —(CH 2 ) x —CH(OR aa )—(CH 2 ) y — in which, R aa  is the protecting group which may be removed in an acidic condition, for example, tetrahydropyranyl etc., or C1-6 alkylene, R a  is the protecting group which may be removed in an acidic condition or an alkaline condition, for example, methoxymethyl or ethylcarbonate etc., and the other symbols are the same meaning as hereinbefore defined, with the proviso that when nitrogen atom in G or M in the formula (I-1a) is free —NH group, NH group in the formula (II-a) is protected by the well-known protecting group (for example, benzyloxycarbonyl (cbz), t-butoxycarbonyl (boc) or trifluoroacetyl (COCF 3 )etc.) 
     by removal of hydroxy-protecting group in an acidic condition, or removal of hydroxy-protecting group in an acidic condition and an alkaline condition two times, succeedingly, (Which reaction may be started first.), if necessary, followed by removal of NH-protecting group. 
     This reaction may be carried out by known methods. For example, the removal of hydroxy-protecting group in an acidic condition may be carried out in a water-miscible organic solvent (methanol, ethanol, tetrahydrofuran (THF) etc.), by using organic acid (acetic acid, p-toluene sulfonic acid, trifluoro acetic acid or trichloro acetic acid etc.) or inorganic acid (hydrochloric acid or hydrobromic acid etc.), at 0-90° C. The removal of hydroxy-protecting group in an alkaline condition may be carried out in an organic solvent (methanol, ethanol, dimethoxyethane or mixture thereof etc.), using an aqueous solution of hydroxide of alkali (sodium hydroxide, potassium hydroxide etc.), hydroxide of alkaline-earth metals (calcium dihydroxide etc.) or carbonate (potassium carbonate etc.) at 0-50° C. 
     As for removal of NH-protecting group, for example, the removal of cbz group may be carried out under an atmosphere of hydrogen gas, in an organic solvent (methanol, ethanol or THF etc.), by using catalyst (Pd—C, Pd or Ni etc.), at 0-50° C. The removal of boc may be carried out in a water-miscible organic solvent (methanol, ethanol or THF etc.), by using organic acid (acetic acid, p-toluene sulfonic acid, trifluoro acetic acid or trichloro acetic acid etc.) or inorganic acid (hydrochloric acid or hydrobromic acid etc.), at 0-90° C. The removal of COCF 3  may be carried out, for example, in a water-miscible organic solvent (methanol, ethanol, THF, dimethoxyethane or mixture thereof etc.), using an aqueous solution of hydroxide of alkali (sodium hydroxide, potassium hydroxide etc.), hydroxide of alkaline-earth metals (calcium dihydroxide etc.) or carbonate (potassium carbonate etc.) at 0-50° C. 
     (b) In the present invention compounds of the formula (I-1), the compounds wherein L is —(CH 2 ) m —CH═CH—(CH 2 ) n —, i.e., the compounds of the formula (I-1b)                           
     wherein L b  is —(CH 2 ) m —CH═CH—(CH 2 ) n —, and the other symbols are the same meaning as hereinbefore defined 
     may be prepared from the compounds of the formula (II-b)
