The invention relates to compounds of formula: <IMAGE> I in which: A is selected from O or S; B is selected from C or N; Z1 is selected from C1-C4 alkylene or phenylene; Z2 is C1-C4 alkylene; W is NR1R2, in which R1 is selected from H or C1-C4 alkyl and R2 is selected from H, C1-C4 alkyl, CONQ1Q2 or CSNQ1Q2 in which Q1 and Q2 are independently selected from H or C1-C4 alkyl, SO2Q3 or COQ3 in which Q3 is C1-C4 alkyl, COOQ4 in which Q4 is selected from C1-C4 alkyl or benzyl, or R1 and R2 taken together with N form a saturated heterocycle, or W is selected from C1-C4 alkoxy or thioalkoxy, CONQ1Q2 or CSNQ1Q2, pyridyl, imidazolyl or COOQ5 in which Q5 is C1-C5 alkyl; R3 is not present when B is N, or is H, C1-C8 alkyl or halogen; Ar1 is selected from optionally substituted phenyl, thienyl, furyl, indolyl, naphthyl or benzyl or Ar1 and R3 taken together form a phenylalkylene group; Ar2 is selected from pyrimidinyl, quinolyl, isoquinolyl, indolyl, isoindolyl or pyridyl, optionally substituted; as well as their salts. |
