This invention relates to a diamine derivative represented by the following formula (1) or a salt thereof. wherein R.sup.1 represents H, OH, an aralkyloxy group or a halogen atom; R.sup.2 represents H or a lower alkyl group; A represents --C(R.sup.3).dbd.CH--, --CH.dbd.N--, --N(R.sup.4)--, R.sup.3 being H or OH, R.sup.4 being a lower alkyl group or an alkoxyalkyl group, --O--, or --S--; B represents a single bond, --C(R.sup.5)(R.sup.6)--(CH.sub.2).sub.k --, R.sup.5 and R.sup.6 being H or a lower alkyl group, and k being a value of from 0 to 2, --S(O).sub.q CH(R.sup.7), or --CH.dbd.CH--; E represents a single bond or --(CH.sub.2).sub.3 --; W and Y individually represent --CH.sub.2 -- 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 --(CH.sub.2).sub.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.
该发明涉及以下式(1)所表示的二胺衍生物或其盐。其中R.sup.1代表H、OH、芳基氧基团或卤原子;R.sup.2代表H或低碳基团;A代表--C(R.sup.3).dbd.CH--、--CH.dbd.N--、--N(R.sup.4)--,其中R.sup.3为H或OH,R.sup.4为低碳基团或烷氧基烷基团,--O--或--S--;B代表单键、--C(R.sup.5)(R.sup.6)--(CH.sub.2).sub.k --,其中R.sup.5和R.sup.6为H或低碳基团,k为0至2的值,--S(O).sub.q CH(R.sup.7),或--CH.dbd.CH--;E代表单键或--(CH.sub.2).sub.3--;W和Y分别代表--CH.sub.2--或--CO--;Z代表O或S;m为2或3的值,n为1至4的值;但E为--(CH.sub.2).sub.3--当B为单键时,且当B为除单键以外的团时,E为单键。该二胺衍生物或其盐具有抗白三烯作用和抗组胺作用,并且在大脑穿透性低,因此可用作哮喘的预防和治疗。
