The invention relates to the compounds of the formula ##STR1## wherein the C(=NOH)-NH.sub.2 group may be in tautomeric form, and pharmaceutically acceptable salts thereof, in which: R.sub.1 is amino or amino which is mono- or disubstituted by a substituent selected from an aliphatic hydrocarbon radical, an araliphatic hydrocarbon radical, an aromatic radical, and a cycloaliphatic hydrocarbon radical or is amino which is disubstituted by a divalent aliphatic hydrocarbon radical or a said radical interrupted by oxygen; R.sub.2 is hydrogen, halogen, trifluoromethyl, an aliphatic hydrocarbon radical or hydroxy; or R.sub.2 is hydroxy which is etherified by an aliphatic alcohol, araliphatic alcohol, or aromatic alcohol or which is esterified by an aliphatic or araliphatic carboxylic acid; or R.sub.2 is hydroxy which is etherified by an aliphatic alcohol which is substituted by carboxy, by esterified carboxy or by amidated carboxy; 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; and R.sub.3 and R.sub.4, independently of one another, are hydrogen, halogen, trifluoromethyl, an aliphatic hydrocarbon radical, hydroxy or hydroxy which is etherified by an aliphatic 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 alcohol or which is esterified by an aliphatic or araliphatic carboxylic acid; 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.
