-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.

for a parallel synthesis. A solid-phase approach based on the alkylation by alcohols of a new supported N-hydroxyphthalimide reagent using a Mitsunobu reaction followed by methylaminolysis has been optimized. This study points out the importance of the linker and a specific base effect for the Mitsunobu reaction. A large variety of alcohols can be used to give with moderate to high yields diverse O-alkyl

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. [FR] L'invention concerne des composés de formule (I) dans laquelle les groupes sont tels que définis dans le descriptif, qui sont utilisés pour la préparation de médicaments pour le traitement de troubles cardio-vasculaires, en particulier l'insuffisance cardiaque et l'hypertension. Les composés sont des inhibiteurs de l'activité enzymatique de Na+, K+-ATPase. On les utilise pour préparer un médicament destiné au traitement d'une maladie provoquée par les effets d'hypertension de l'ouabaïne endogène, par exemple la progression de l'insuffisance rénale dans la maladie rénale polycystique autosomique dominante (ADPKD), l'hypertension prééclamptique et la protéinurie et la progression de l'insuffisance rénal chez les patients présentant des polymorphismes de l'adducine.
Novel Analogues of Istaroxime, a Potent Inhibitor of Na<sup>+</sup>,K<sup>+</sup>-ATPase: Synthesis and Structure−Activity Relationship
We report the synthesis and biological properties of novel inhibitors of the Na(+),K(+)-ATPase as positive inotropic compounds. Following our previously described model from which Istaroxime was generated, the 5alpha,14alpha-androstane skeleton was used as a scaffold to study the space around the basic chain of our lead compound. Some compounds demonstrated higher potencies than Istaroxime on the receptor
