The invention relates to a compound having general formula (I): wherein n is
equal to 3; R1 is an ethyl or isopropyl group; each of the R2 groups
is independently of each other a hydrogen atom, a C1-C3 alkyl
group or a halogen atom; one of the R3 and R4 groups represents
a hydrogen atom while the other of the R3 and R4 groups represents
an OH or OR5 group, where R5 can be a C2-C7
acyl group, an alkyl(C1-C6)animo-carbonyl group, an
aralkyl(C1-C6)aminocarbonyl optionally substituted on the
aryl, an arylcarbonyl group optionally substituted or a heteroarylaminocarbonyl
