Naphthalene derivatives represented by formula [I]:
(wherein A is a hydrogen atom, a hydroxy group, a C7-C11 aralkyloxy group, or an alkoxy group composed of an oxy group and a C1-C12 aliphatic or alicyclic, saturated or unsaturated hydrocarbon group where the alkyl may be substituted with a C6-C10 allyloxy group; B represents O, S, CH2, O-CH2, S-CH2, CO, or CHOR1; C represents CO, CR2R3CO, CH2CH2CO, or CH=CHCO; D represents a hydrogen atom, NO2, NH2, CO2R4, or a group having the following formula [II]:
(wherein G represents a hydrogen atom, OH, SO2NH2, CO2R6, CN, or a tetrazol-5-yl group); E represents a hydrogen atom, OH, SO2NH2, CO2R5, CN, or a tetrazol-5-yl group; F represents a hydrogen atom, a C1-C4 lower alkyl group, a nitro group , or a halogen atom; and R1, R2, R3, R4, R5 and R6 are, independently each other, a hydrogen atom or a C1-C4 lower alkyl group);
pharmacologically acceptable salts thereof, or pharmacologically acceptable solvates thereof, which have, for example, an inhibitory effect on the production of IgE antibodies, and will be useful for prophylaxis and/or treatment of allergic diseases.
式[I]代表的萘衍生物:
(其中 A 是氢原子、羟基、C7-C11 芳氧基或由氧基和 C1-C12 脂肪族或脂环族、饱和或不饱和烃基组成的烷氧基,其中烷基可被 C6-C10 烯丙氧基取代;B 代表 O、S、CH2、O-CH2、S-CH2、CO 或 CHOR1; C 代表 CO、CR2R3CO、CH2CH2CO 或 CH=CHCO; D 代表氢原子、NO2、NH2、CO2R4 或具有下式[II]的基团:
(其中 G 代表氢原子、OH、SO2NH2、CO2R6、CN 或四唑-5-基团);E 代表氢原子、OH、SO2NH2、CO2R5、CN 或四唑-5-基团;F 代表氢原子、C1-C4 低级烷基、硝基或卤素原子;以及 R1、R2、R3、R4、R5 和 R6 相互独立地为氢原子或 C1-C4 低级烷基);
