Title
(EN) SUBSTITUTED QUINAZOLINES
(FR) QUINAZOLINES SUBSTITUÉES
Abstract
(EN) This invention relates to the discovery of 3-and 5-substituted analogues of the selective platelet lowering agent anagrelide with reduced potential for cardiovascular side-effects which should lead to improved patient compliance and safety in the treatment of myeloproliferative diseases. More specifically, the present invention relates to certain imidazoquinazoline derivatives which have the general formula shown below wherein the substituents have the meanings defined in claim 1: and which have utility as platelet lowering agents in humans. The compounds of the present invention function by inhibiting megakaryocytopoeisis and hence the formation of blood platelets.
(FR) L'invention concerne la découverte d'analogues substitués en position 3 et 5 de l'anagrélide, un agent de réduction sélective du nombre des plaquettes, présentant un potentiel réduit d'effets secondaires cardiovasculaires et qui devraient conduire à une observance thérapeutique et à une sécurité améliorées dans le traitement de syndromes myéloprolifératifs. Plus spécifiquement, la présente invention concerne certains dérivés d'imidazoquinazoline représentés par la formule générale décrite ci-dessous, dans laquelle les substituants présentent les significations définies dans la revendication 1, et qui présentent une utilité en tant qu'agents de réduction du nombre des plaquettes chez les êtres humains. Les composés de la présente invention agissent en inhibant la mégacaryocytopoïèse et par conséquent la formation des plaquettes sanguines.
