Abstract

A compound of the formula: ##STR1## wherein A is the group of the formula: Ar.sup.1 --D--Ar.sup.2 -- wherein Ar.sup.1 is a phenyl or thienyl group which may be optionally substituted with at least one of the same or different halogen atom; Ar.sup.2 is a phenylene or thienylene group which may be optionally substituted with at least one of the same or different halogen atom; D is a divalent radical selected from the group consisting of >C.dbd.N--OR .sup.4 [wherein R.sup.4 is a hydrogen atom or lower alkyl group], >C.dbd.O, ##STR2## >CHOH, >NH radical, or single bond, ##STR3## wherein R.sup.5 is a lower alkoxy or phenyl group which may be optionally substituted with at least one of the same or different halogen atom; E is a methine group or a nitrogen atom; F is a vinylene group or an oxygen atom, ##STR4## wherein R.sup.6 is a lower alkoxy group; R.sup.7 is a lower alkyl group; R.sup.8 is a benzoyl group which may be optionally substituted with at least one of the same or different halogen atom, B is a divalent azole group; R.sup.1 is a hydrogen atom or a lower alkyl group; R.sup.2 is a hydrogen atom, lower alkyl, aryl-lower alkyl, or the group of the formula: R.sup.9 --G-- wherein R.sup.9 is a hydrogen atom, lower alkyl, halo-lower alkyl, amino-lower alkyl, aryl or aryl-lower alkyl group or the group of the formula: ##STR5## wherein R.sup.10 is a hydrogen atom or lower alkyl group; R.sup.11 is a hydrogen atom, lower alkyl, lower alkenyl, lower cycloalkyl, aryl-lower alkyl, aryl or aroyl group; or the group of the formula: --NR.sup.10 R.sup.11 is a 5-, 6- or 7-membered saturated heterocyclic ring; or the group of the formula: R.sup.12 --O-- wherein R.sup.12 is a lower alkyl or polyhalo-lower alkyl group; G is a divalent group selected from the group consisting of >C.dbd.O, >C.dbd.S, >(C.dbd.O).sub.2 or >SO.sub.2 radical; or the group of the formula: --NR.sup.1 R.sup.2 is a 5-, 6- or 7-membered saturated heterocyclic ring: R.sup.3 is a hydrogen atom or lower alkyl group, or its acid addition salts, which is useful for immunomodulator.
