The present invention realtes to the synthesis fo a new class of indeno [1,2- c]pyrazol-4-ones of formula (I): that are potent inhibitors of the class of enzymes known as cyclin dependent kinases, which relate to the catalytic subunits cdk1-9 and their regulatory subunits know as cyclins A-H. The invention also provides a novel method of treating cancer or otehr profiferative disease by administering a therapeutically effective amount of one of these compounds or a pharmaceutically acceptable salt form thereof. Alternatively, one can treat cancer or other proliferative disease by administering a therapeutically effective combination of one of the compounds of teh present invention and one or more other known anti-cancer or anti- proliferative agents.

La présente invention concerne la synthèse d'une nouvelle classe de indéno [1,2-c]pyrazol-4-ones représentés par la formule (I), qui sont des inhibiteurs puissants de la classe des enzymes connues sous l'appellation de kinases dépendantes des cyclines, qui sont liés aux sous unités catalytiques cdk1-9 et à leurs sous unités régulatrices connues sous l'appellation de cyclines A-H. Cette invention concerne aussi une nouvelle technique de traitement du cancer ou d'autres maladies proliférantes, qui consiste à administrer une quantité thérapeutiquement efficace de l'un de ces composés ou d'un sel de ceux-ci répondant aux normes pharmaceutiques. Dans un autre mode de réalisation de cette invention, on peut traiter le cancer ou d'autres maladie proliférantes en administrant une combinaison thérapeutiquement efficace de l'un de ces composés et d'un ou de plusieurs autres agents anticancéreux ou inhibiteurs de la prolifération connus.
