R2 represents a hydrogen atom or a straight or branched alkyl group of from 1 to 6 carbon atom(s).
R3 represents a hydrogen atom, a halogen atom, a hydroxy group, a nitro group, a group of general formula: -COOR7 [wherein R7 represents a hydrogen atom or a straight or branched alkyl group of from 1 to 6 carbon atom(s).) or a straight or branched alkyl, alkoxy or alkylthio group of from 1 to 6 carbon atom(s).
R4 represents
(i) when symbol B represents a closed ring, a group of general formula:
or
(wherein symbol U represents an oxygen atom or a sulphur atom. R8 represents a hydrogen atom or a straight or branched alkyl group of from 1 to 6 carbon atom(s). n and m represent an integer of from 1 to 10, respectively, p and q represent zero or an integer of from 1 to 10, respectively.) or
(ii) when symbol B do not represent a ring, a group of general formula:
or
(wherein R8, p and q represent the same meaning as depicted hereinbefore. With the proviso that, when the symbol B represents a group of formula:
p does not represent zero).
With the proviso that, following compounds are excluded, i.e. compounds of general formula:
(wherein the symbol A' is a vinylene or ethylene group optionally being substituted by straight or branched alkyl group(s) of from 1 to 4 carbon atom(s), R4' is the general formula:
(wherein all the symbols are the same meaning as depicted hereinbefore.) and R1' is
(i) a group of the general formula:
(wherein R5' and R6' are hydrogen atom(s), hydroxy group(s), halogen atom(s), straight or branched alkyl, alkenyl, alkynyl, alkoxy, alkenyloxy, alkynyloxy or acyloxy group(s) of from 1 to 4 carbon atom(s) or cycloalkyl group(s) of from 3 to 6 carbon atom(s), independently.) or (ii) a group of the general formula:
(wherein R5' and R6' are the same meaning as depicted hereinbefore.)) or non-toxic salts thereof possess an antagonistic activity on leukotrienes (SRS), inhibitory activity on 5a-reductase, on phospholipase and on aldose reductase and are therefore useful for the prevention and/or treatment for diseases induced by leukotrienes, 5a-reductase, phospholipase and aldose reductase in mammals, especially human beings.
