This invention relates to a diamine derivative represented by the following formula (1) or a salt thereof.
wherein R1 represents H, OH, an aralkyloxy group or a halogen atom; R2 represents H or a lower alkyl group; A represents -C(R3)=CH-, -CH=N-, -N(R4)-, R3 being H or OH, R4 being a lower alkyl group or an alkoxyalkyl group, -O-, or -S-; B represents a single bond, -C(R5)(R6)-(CH2)k-, R5 and R6 being H or a lower alkyl group, and k being a value of from 0 to 2, -S(O)qCH(R7), or -CH=CH-; E represents a single bond or -(CH2)3-; W and Y individually represent -CH2- or -CO-; Z represents O or S; and m is a value of 2 or 3, and n is a value of from 1 to 4; with the proviso that E is -(CH2)3- when B is a single bond and E is a single bond when B is a group other than a single bond. The diamine derivatives or salts thereof have both antileukotrienic action and antihistaminic action and are low in brain penetration, and are hence useful as asthma preventives and curatives.
本发明涉及下式(1)所代表的二胺衍生物或其盐。
其中 R1 代表 H、OH、烷氧基或卤原子;R2 代表 H 或低级烷基;A 代表 -C(R3)=CH-、-CH=N-、-N(R4)-,R3 为 H 或 OH,R4 为低级烷基或烷氧基烷基、-O- 或 -S-;B 代表单键、-C(R5)(R6)-(CH2)k-,R5 和 R6 为 H 或低级烷基,k 的值为 0 至 2、-S(O)qCH(R7) 或 -CH=CH-;E代表单键或-(CH2)3-;W和Y分别代表-CH2-或-CO-;Z代表O或S;m的值为2或3,n的值为1至4;但当B为单键时,E为-(CH2)3-,当B为单键以外的基团时,E为单键。二胺衍生物或其盐类具有抗白三烯作用和抗组胺作用,对大脑的渗透性低,因此可作为哮喘的预防和治疗药物。
