  • Patent number: 9206133
    Abstract: The present invention provides a new process of synthesis of a polymorph of 7-chloro-4-(piperazin-1-yl)-quinoline of Formula I. Said quinoline compound is substantially pure of any impurities. The present invention further provides the use of the above-mentioned polymorph of 7-chloro-4-(piperazin-1-yl)-quinoline in the synthesis of piperaquine or one of its pharmaceutically acceptable salts.
    Type: Grant
    Filed: June 5, 2012
    Date of Patent: December 8, 2015
    Assignee: Sigma-Tau Industrie Farmaceutiche Riunite S.p.A.
    Inventors: Walter Cabri, Roberto Castagnani, Silvia Armaroli, Gianandrea Quattrociocchi, Vincenzo Colangeli

  • Patent number: 8609644
    Abstract: Compounds of formula (I) wherein: the groups are as defined in the description, are useful for the preparation of medicaments for the treatment of cardiovascular disorders, in particular heart failure and hypertension. The compounds are inhibitors of the enzymatic activity of the Na+, K+-ATPase. Said compounds are used for the preparation of a medicament for the treatment of a disease caused by the hypertensive effects of endogenous ouabain, such as renal failure progression in autosomal dominant polycystic renal disease (ADPKD), preeclamptic hypertension and proteinuria and renal failure progression in patients with adducin polymorphisms.

  • Patent number: 8269007
    Abstract: This invention relates to a process for preparing a crystalline form of (4S)-11(dimethoxymethyl)-4-ethyl-4-hydroxy-1H-pyrano[3?4?:6,7]indolizino[1,2-b]quinoline-3,14(4H,12H)-dione, also named 7-(dimethoxy-methyl)camptothecin). With the provision of a particular crystallization step, in appropriate way, a new crystalline form of the above compound is obtained. The process for the preparation of the polymorph Form II comprises transforming camptothecin to the corresponding 7-(dimethoxy-methyl)-camptothecin, and crystallizing from methanol.
