The present invention provides pharmaceutical compositions comprising substituted 1,4 naphthoquinones that are effective in preventing oligomerization of beta amyloid and subsequent pathologies associated with amyloid fibrils. These compositions are useful for the treatment of disease involving amyloidogenesis including neurodegenerative diseases such as Alzheimer's Disease or senile dementia. Particularly effective compositions comprise 1,4 naphthoquinones substituted with an amino acid residue selected from a heterocyclic or aromatic amino acid.

showed that microwave assisted synthesis is the best method for the synthesis of naphthoquinone amino acid and chloride-naphthoquinone amino acid derivatives by a complete evaluation of reaction conditions such as stoichiometry, bases, and pH influence. Following the same strategy, we synthesized chloride and non-chloride tyrosine, valine, and tryptophan-naphthoquinones achieving 85–95%, 80–92%, and 91–95%
