ABSTRACT:
The present invention relates to novel compounds of formula (I):in which:R1, R2and R3, which are identical or different, are each independently:a (C1-C6)alkyl group,a pyridinyl group ora group —CH2—NR4R5, in which R4and R5are each independently a hydrogen atom or a (C1-C4)alkyl group, or alternatively R4and R5form, with the nitrogen atom to which they are bonded, a pyrrolidinyl, piperidinyl, hexahydroazepinyl, morpholinyl or piperazinyl group,with the proviso that at least one of the substituents R1, R2and R3is other than a (C1-C6)alkyl group,and their salts, solvates and hydrates, especially those which are pharmaceutically acceptable.These compounds are useful particularly for the treatment of disorders of the venous circulation.
