  • Publication number: 20140309213
    Abstract: This invention relates to compounds of Formula I-VI having the following general structure: Z1—Y1—(CH2)n1—R—(CH2)n2—Y2—Z2 wherein R is a 6-8 membered saturated heterocyclic ring having 2 Nitrogen atoms connected with —(CH2)n1— and —(CH2)n2—, respectively, and pharmaceutically acceptable salts thereof which are inhibitors of the Renal Outer Medullary Potassium (ROMK) channel (Kir1.1). The compounds are useful as diuretics and natriuretics and therefore are useful for the therapy and prophylaxis of disorders resulting from excessive salt and water retention, including cardiovascular diseases such as hypertension and chronic and acute heart failure.
