The present invention is related to a family of furan-imidazolone derivatives of formula (I), and to their use in the treatment of cognitive, neurodegenerative or neuronal diseases or disorders, such as Alzheimer's disease or Parkinson's Disease. The present invention also relates to pharmaceutical compositions comprising the same.
The decomposition of some NG-(ω-aminoalkanoyl)argininamides, which are key intermediates for the preparation of radiolabeled and fluorescent neuropeptide Y receptor ligands, prompted us to synthesize a small series of simple 1-(ω-aminoalkanoyl)guanidines, and to investigate these model compounds for stability in alkaline buffers. The degradation of acylguanidines was monitored by time resolved UV spectroscopy

From outer space: Twelve meteorite specimens, representative of their major classes, catalyse the synthesis of nucleobases, carboxylic acids, aminoacids and low‐molecular‐weight compounds from formamide (see figure). Different chemical pathways are identified, the yields are high for a prebiotic process and the products come in rich and composite panels.

Attempts to prepare glycocyamidine by the cyclization of ethyl guanidoacetate in aqueoussolutions gave mixtures of guanidoacetic acid and glycocyamidine. The properties of a sample of pure glycocyamidine, which was obtained from the reaction of guanidine with ethyl glycinate, are described.

Water-soluble prodrug strategy is a practical alternative for improving the drug bioavailability of sparingly-soluble drugs with reduced drug efficacy. Many water-soluble prodrugs of sparingly-soluble drugs, such as the phosphate ester of a drug, have been reported. Recently, we described a novel water-soluble prodrug based on O–N intramolecular acyl migration. However, these prodrugapproaches require a
