wherein
R represents a hydrogen atom or a halogen atom
X represents nitrogen or -CH-group
W represents a -NH-CO-, -CH=CH-, -CH₂-CH₂- group, oxygen or sulfur
R₁ represents a hydrogen atom or a C₁₋₄ alkyl group
n is 0 or 1
Y represents sulfur or a -CH- group
A represents carbon or nitrogen
B represents a -CH- group (provided that A is different from nitrogen), -COO-, -CO-, or -CH₂- group
m is 0 or an integer from 1 to 3
Z represents -NH-, -CO-, -COO- or -CH- group, or it is absent
p is 0 or 1
Het represents piperazinyl, homopiperazinyl, piperidinyl, tropyl or tetrahydropirimidinyl group, each group being optionally substituted by a C₁₋₄ alkyl group or an amino group
q is 0 or 1
R₂ represents a hydrogen atom, a C₁₋₄ alkyl group or an amino group optionally substituted by a linear or branched C₁₋₄ alkyl group or phenyl group
R₃ represents a linear or branched C₁₋₈alkyl group or a hydrogen atom (provided that the bond between Het and the group
is a carbon- carbon bond or A=C and B=CH), or
R₂ and R₃ may join together to form a heterocyclic 5-membered ring, tautomers thereof and acid addition salts of the aforesaid compounds.
The process for the preparation of the compounds of formula (I) as well as pharmaceuticals compositions containing them are also described.
