  Discovery of phenyl alanine derived ketoamides carrying benzoyl residues as novel calpain inhibitors

  摘要：

  Novel calpain inhibitors derived from phenyl alanine aldehydes or ketoamides carrying a benzoyl residue were prepared and evaluated for their biological potency. A brief structure-activity relationship elucidated the importance of ortho-substitutents in the benzoyl moiety. The most potent derivative, the ketoamide 19c, exhibited a K, of 6 nM and represents a novel class of reversible, highly potent and non-peptidic calpain inhibitors. (C) 2002 Elsevier Science Ltd.

  Synthesis and biological evaluation of novel piperidine carboxamide derived calpain inhibitors

  摘要：

  Calpain inhibitors which are derived from piperidine carboxamides in the P-2 legion were prepared and evaluated for mu-calpain inhibition. In particular, the keto amides 11f and 11j have K-i of 30 and 9 nM and display a more than 100-fold selectivity over the closely related cysteine protease cathepsin B. Furthermore, these compounds inhibit NMDA induced convulsions in mice indicating that calpain inhibition in brain results in some anticonvulsive properties. (C) 2000 Elsevier Science Ltd.

  This invention is directed to novel aliphatic prolinamide derivatives of Formula I, and pharmaceutically acceptable salts, solvates, solvates of the salt and prodrugs thereof, useful in the prevention (e.g., delaying the onset of or reducing the risk of developing) and treatment (e.g., controlling, alleviating, or slowing the progression of) of age-related macular degeneration (AMD) and related diseases of the eye. These diseases include dry-AMD, wet-AMD, geographic atrophy, diabetic retinopathy, retinopathy of prematurity, polypoidal choroidal vasculopathy, and degeneration of retinal or photoreceptor cells. The invention disclosed herein is further directed to methods of prevention, slowing the progress of, and treatment of dry-AMD, wet-AMD, and geographic atrophy, diabetic retinopathy, retinopathy of prematurity, polypoidal choroidal vasculopathy, and degeneration of retinal or photoreceptor cells, comprising: administration of a therapeutically effective amount of compound of the invention. The compounds of the invention are inhibitors of HTRAl. Thus, the compounds of the invention are useful in the prevention and treatment of a wide range of diseases mediated (in whole or in part) by HTRAl. The compounds of the invention are also useful for inhibiting HTRAl protease activity in an eye or locus of an arthritis or related condition.
