A drug containing, as an active ingredient, a compound having an antagonistic activity against an EP.sub.2 receptor in the prevention and/or treatment of a disease associated with the activation of an EP.sub.2 receptor, of formula (I-A):

##STR00001##

wherein all symbols have the same meanings as those described in the specification, or a pharmaceutically acceptable salt thereof.

The present invention provides: a 3-alkoxybenzamide derivative having an excellent pest control effect, or a salt thereof; and a pest control agent and a production intermediate which contain the same as an active ingredient.

Provided are: a 3-alkoxybenzamide derivative represented by general formula [I]

##STR00001##

[In the formula, A represents an oxygen atom or a sulfur atom, G represents a hydrogen atom, a halogen atom, or a C.sub.1-C.sub.6 alkyl group, le represents a C.sub.1-C.sub.6 alkyl group, a C.sub.3-C.sub.6 cycloalkyl group, etc., R.sup.2 represents a hydrogen atom, etc., R.sup.3 represents a halogen atom, C.sub.1-C.sub.6 alkyl group, etc., R.sup.4 represents a halogen atom, C.sub.1-C.sub.6 alkyl group, etc., and R.sup.5 represents a C.sub.1-C.sub.12 alkyl group, etc.], or a salt thereof; and a pest control agent characterized by containing said derivative or salt thereof as an active ingredient.

The present invention aims to provide a polymerizable compound that has high storage stability without causing crystal precipitation when added to a polymerizable composition and to provide a polymerizable composition containing the polymerizable compound. A polymer film produced by polymerization of the polymerizable composition has a low haze, high thickness uniformity, low occurrence of nonuniform orientation, high surface hardness, high adhesiveness, and good appearances and fewer orientation defects even after ultraviolet irradiation. The present invention also aims to provide a polymer produced by polymerization of the polymerizable composition and an optically anisotropic body produced from the polymer.

An object of the present invention is to provide a DP receptor antagonist. A compound represented by general formula (I):

##STR00001## (wherein all symbols are as shown in the specification) and a pharmaceutically acceptable salt thereof have DP receptor antagonistic activity and are also highly safe, and thus are useful as active ingredients of pharmaceuticals for DP receptor-mediated diseases. In addition, the compound represented by the general formula (I) and the pharmaceutically acceptable salt thereof also have good transferability to the central nervous system, and thus are particularly useful as a preventive and/or therapeutic agent for diseases associated with DP receptors present in the central nervous system among DP receptor-mediated diseases, that is, sleep-wake disorders.
