A method for inhibiting the effects of LTB.sub.4 comprises administration of an effective amount of a compound represented by the following structural formula (I) ##STR1## wherein m is 1 or 2; n is 1, 2 or 3; p is 0, 1, or 2; R' is hydrogen or methyl; R is phenyl substituted with A, R.sub.1 and R.sub.2 wherein R.sub.1 and R.sub.2 are independently selected from either (1) (S).sub.a --(CH.sub.2).sub.b --(T).sub.c --B wherein a is 0 or 1; b is 5 to 12; c is 0 or 1; S and T are independently sulfur, oxygen, or CH.sub.2 with the proviso that S or T are not sulfur when p is 1 or 2; and B is C.sub.1-4 alkyl, ethynyl, trifluoromethyl, or phenyl optionally monosubstituted with Br, Cl, CF.sub.3, C.sub.1-4 alkoxy, C.sub.1-4 alkyl, methylthio, or trifluoromethylthio; or (2) hydrogen bromo, chloro, methyl, trifluoromethyl, methoxy or nitro; and A is selected from (2) as defined above or a pharmaceutically acceptable salt thereof. Such methods are useful in the treatment of diseases in which LTB.sub.4 is a factor.
抑制LTB.sub.4作用的方法包括施用有效量的以下结构式(I)所示的化合物:##STR1## 其中m为1或2;n为1、2或3;p为0、1或2;R'为氢或甲基;R为被A、R.sub.1和R.sub.2取代的苯基,其中R.sub.1和R.sub.2独立地选自以下任一项:(1) (S).sub.a --(CH.sub.2).sub.b --(T).sub.c --B,其中a为0或1;b为5至12;c为0或1;S和T独立地为硫、氧或CH.sub.2,但条件是当p为1或2时,S或T不是硫;B为C.sub.1-4烷基、乙炔基、三氟甲基或苯基,可选地单取代有Br、Cl、CF.sub.3、C.sub.1-4烷氧基、C.sub.1-4烷基、甲基硫基或三氟甲基硫基;或(2)氢、溴、氯、甲基、三氟甲基、甲氧基或硝基;A选自上述(2)定义的项或其药用可接受盐。此类方法可用于治疗LTB.sub.4为因素的疾病。
