N-acylhydrazonic compounds, use in the treatment of amyloid and non-amyloid degenerative aggregopathies, and pharmaceutical composition

Abstract

The present invention relates to a family of N-acylhydrazonic compounds structurally derived from 1-methyl-1H-imidazole-2-carboxaldehyde, or pharmaceutically acceptable salts thereof, and the use of said compounds to prevent and/or treat amyloid (such as Alzheimer's, Parkinson's and type 2 diabetes) and non-amyloid (such as cataracts) degenerative aggregopathies These compounds act as attenuators of the metal-protein interaction, preventing and/or decreasing protein oligomerization through competition with the target peptide or protein for the binding of physiological metal ions and, possibly, by modulating the protein-protein interaction itself. The invention also details four compounds specifically described as examples of N-acylhydrazones derived from 1-methyl-1H-imidazole-2-carboxaldehyde, namely: 1-methyl-1H-imidazole-2-carboxaldehyde isonicotinoyl hydrazone, 1-methyl-1H-imidazole-2-carboxaldehyde benzoyl hydrazone, 1-methyl-1H-imidazole-2-carboxaldehyde 2-furoyl hydrazone and 1-methyl-1H-imidazole-2-carboxaldehyde 2-thiophenyl hydrazone. The current application also comprises pharmaceutical compositions.
