The invention relates to the compounds of the formula ##STR1## wherein the C(.dbd.NH)--NHR group may be in tautomeric or isomeric form, and pharmaceutically acceptable salts thereof, in which: R is hydrogen or an acyl radical which is derived from an organic carbonic acid, an organic carboxylic acid, a sulfonic acid, or a carbamic acid; R.sub.1 is a substituent selected from an aliphatic hydrocarbon radical, an araliphatic hydrocarbon radical and a cycloaliphatic hydrocarbon radical; X.sub.1 and X.sub.3, independently of one another, are oxygen (--O--) or sulphur (--S--); and X.sub.2 is a divalent aliphatic hydrocarbon radical which may be interrupted by an aromatic radical; wherein the phenyl rings of formula I may be, independently of one another, further substituted by one or more substituents selected from halogen, trifluoromethyl, an aliphatic hydrocarbon radical, hydroxy, and hydroxy which is etherified by an aliphatic, araliphatic or cycloaliphatic alcohol or which is esterified by an aliphatic or araliphatic carboxylic acid; wherein aryl in the above definitions may be, independently of one another, further substituted by one or more substituents selected from halogen, trifluoromethyl, an aliphatic hydrocarbon radical, hydroxy, and hydroxy which is etherified by an aliphatic, araliphatic or cycloaliphatic alcohol or which is esterified by an aliphatic or araliphatic carboxylic acid; and wherein a cycloaliphatic hydrocarbon radical may be substituted by an aliphatic radical. The compounds are useful as selective LTB.sub.4 receptor antagonists in the treatment of conditions or syndromes in mammals which are responsive to LTB.sub.4 receptor antagonism.
本发明涉及公式##STR1##的化合物及其药学上可接受的盐,其中:C(.dbd.NH)--NHR基团可以处于互变异构或同分异构形式,R为氢或由有机碳酸、有机羧酸、磺酸或氨基甲酸衍生的酰基基团;R.sub.1为从脂肪烃基、芳基脂肪烃基和环烷基脂肪烃基中选择的取代基;X.sub.1和X.sub.3独立地为氧(--O--)或硫(--S--);X.sub.2为二价脂肪烃基,其可以由芳香基中断;在公式I中的苯环可以独立地进一步由卤素、三氟甲基、脂肪烃基、羟基和由脂肪烷基、芳基脂肪烷基或环烷基醇醚化的羟基或由脂肪烷基或芳基脂肪酸酯化的羟基的一个或多个取代基取代;在上述定义中的芳基可以独立地进一步由卤素、三氟甲基、脂肪烃基、羟基和由脂肪烷基、芳基脂肪烷基或环烷基醇醚化的羟基或由脂肪烷基或芳基脂肪酸酯化的羟基的一个或多个取代基取代;其中环烷基脂肪烃基可以由脂肪烃基取代。这些化合物在哺乳动物对LTB.sub.4受体拮抗作用有反应的情况或综合症的治疗中作为选择性LTB.sub.4受体拮抗剂是有用的。
