  • Patent number: 10259821
    Abstract: Novel tetrahydroisoquinoline derivative compounds are disclosed herein that may be used as an active ingredient for a pharmaceutical composition, and in particular, for a pharmaceutical composition useful for preventing or treating a disease or condition responsive to modulation of the contractility of the skeletal sarcomere. This may be accomplished, for example, by modulation of the troponin complex of the fast skeletal muscle sarcomere through one or more of fast skeletal myosin, actin, tropomyosin, troponin C, troponin I, and troponin T, and fragments and isoforms thereof. The tetrahydroisoquinoline derivative compounds can thus be used as an agent for preventing or treating 1) neuromuscular disorders, 2) disorders of voluntary muscle, 3) CNS disorders in which muscle weakness, atrophy, and fatigue are prominent symptoms, 4) muscle symptoms stemming from systemic disorders, and 5) dysfunctions of pelvic floor and urethral/anal sphincter muscle.

  • Publication number: 20180327418
    Abstract: The problem to be solved by the present invention is to provide a compound suitable for a pharmaceutical composition, specifically a pharmaceutically composition for treating nocturia. The inventors have assumed that inhibition of nocturnal activity of placental leucine aminopeptidase (P-LAP), i.e. aminopeptidase that cleaves AVP, would maintain and/or increase an endogenous AVP level to enhance the antidiuretic effect, which would contribute to a decreased number of nocturnal voids, and have extensively studied compounds which inhibit P-LAP. As a result, the inventors have found that (2R)-3-amino-2-{[4-(substituted pyridine)-2-yl]methyl}-2-hydroxy-propanoic acid derivatives have excellent P-LAP inhibitory activity. The inventors have evaluated antidiuretic effects in water-loaded rats and have found that the compounds increase endogenous AVP levels by inhibiting P-LAP and consequently reduce urine production.
