Patent

CA 2383999

The present invention provides the compound having formula (I), wherein each of R1 and R2 is, substituted or unsubstituted, aryl, cycloalkyl, cycloalkylamino, naphtha, pyridineamino, piperidino, t-butyl, aryloxy, arylalkyloxy, or pyridine group; wherein A is an amido moiety, -O-, -S-, -NH-, or -CH2-; and wherein n is an integer from 3 to 8. The present invention also provides a method of selectively inducing growth arrest, terminal differentiation and/or apoptosis of neoplastic cells and thereby inhibiting proliferation of such cells. Moreover, the present invention provides a method of treating a patient having a tumor characterized by proliferation of neoplastic cells. Lastly, the present invention provides a pharmaceutical composition comprising a pharmaceutically acceptable carrier and a therapeutically acceptable amount of the compound above.

La présente invention concerne le composé présentant la formule (I), où chaque R¿1? et R¿2? désigne un groupe aryle, cycloalkyle, cycloalkylamino, naphte, pyridineamino, piperidino, t-butyl, aryloxy, arylalkyloxy, ou pyridine, substitué ou non substitué, où A désigne une fraction amido, -O-, -S-, -NH-, ou CH¿2?-, et où n désigne un nombre entier compris entre 3 et 8. La présente invention concerne également un procédé consistant à induire sélectivement un arrêt de la croissance, une différentiation terminale et/ou une apoptose des cellules néoplastiques, ce qui permet d'inhiber la prolifération de ces cellules. Par ailleurs, la présente invention concerne également un procédé destiné au traitement d'un patient atteint d'une tumeur caractérisée par la prolifération de cellules néoplastiques. La présente invention concerne enfin une composition pharmaceutique contenant un excipient pharmaceutiquement acceptable et un dosage thérapeutiquement acceptable du composé décrit.
