A subject of the invention is the compounds of formula (I):
in which
either R1 represents H, OH, NH2, —(CH2)m—NRaRb(m=0.1 or 2),
Ra and Rb represent H, linear, branched or cyclic (C1-C6) alkyl, (C3-C6) cycloalkyl-(C3-C6)— alkyl, Rc, S(O)2Rc, C(O)Rc, S(O)2Rd or C(O)Rd;
or Ra and Rb with N form an Rc radical;
Rc represents a saturated, unsaturated or 5- or 6-members aromatic ring, containing 1 to 4 heteroatoms chosen from N, O and S, optionally substituted;
Rd represents a linear, branched or cyclic (C1-C6) alkyl, optionally substituted by 1 to 4 halogens;
or R1 represents Rc or CHReRc or CHReRd;
Re represents H, OH, NH2, NH—(C1-C6)-alk or N-(C1-C6)-alk2, or NH—(C1-C7)-acyl or NHRc;
R2 represents H, (CH2)m—NRaRb, Rc, CHReRc or CHReRd, and R′2 represents H.
