Abstract
Aim: AMPA-glutamate receptor (AMPAR) dysfunction mediates multiple neurological/neuropsychiatric disorders. Ampakines bind AMPARs and allosterically enhance glutamate-elicited currents. This report describes the activity of the water-soluble ampakine CX1942 prodrug and the active moiety CX1763.Results: CX1763 and CX1942 enhance synaptic transmission in hippocampi of rats. CX1763 increases attention in the 5CSRTT in rats and reduces amphetamine-induced hyperactivity in mice. CX1942 potently reverses opioid-induced respiratory depression in rats. CX1942/CX1763 was effective at 2.5-10 mg/kg. CX1763 lacked epileptogenicity up to 1500 mg/kg in rats.Conclusion: These data document that CX1942 and CX1763 are active and without prominent side effects in multiple pre-clinical assays. CX1942 could serve as a prodrug for CX1763 with the advantage of high water solubility as in an intravenous formulation.
期刊介绍：
Future Medicinal Chemistry offers a forum for the rapid publication of original research and critical reviews of the latest milestones in the field. Strong emphasis is placed on ensuring that the journal stimulates awareness of issues that are anticipated to play an increasingly central role in influencing the future direction of pharmaceutical chemistry. Where relevant, contributions are also actively encouraged on areas as diverse as biotechnology, enzymology, green chemistry, genomics, immunology, materials science, neglected diseases and orphan drugs, pharmacogenomics, proteomics and toxicology.
