Abstract: This invention relates to a compound which is [c]-fused bicyclic proline derivative, or a pharmaceutically acceptable salt thereof; a pharmaceutical composition comprising the compound or the salt thereof, and methods of treating diseases, including, but not limited to, methods of preventing or inhibiting joint cartilage damage and preventing or treating diseases characterized by joint cartilage damage, joint inflammation, or joint pain. The [c]-fused bicyclic proline derivatives are compounds of Formula I as described above. Diseases characterized by joint cartilage damage or joint pain include, for example, osteoarthritis and rheumatoid arthritis. Rheumatoid arthritis is also characterized by joint inflammation. This invention also relates to methods of synthesizing and preparing the [c]-fused bicyclic proline derivatives, or a pharmaceutically acceptable salt thereof.

Abstract: The invention concerns novel renin-inhibitory peptides which are useful for treating renin associated hypertension, hyperaldosternoism, and congestive heart failure. Processes for preparing the peptides, compositions containing them and methods of using them are included. Also included is a diagnostic test using the compounds to determine the presence of renin-associated hypertension or hyperaldosteronism.

Abstract: The invention concerns novel renin-inhibitory peptides which are useful for treating renin associated hypertension and for treating hyperaldosteronism. Novel intermediates, processes for preparing both the intermediates and the novel peptides, pharmaceutical compositions, and methods of treatment are included.
