CX 516, a compound synthesized by Cortex Pharmaceuticals using Ampakine® technology licensed from the University of California, was in clinical investigations for the treatment of Alzheimer's disease, schizophrenia, fragile X syndrome and autism, and sleep disorders, however, development of this drug candidate has been discontinued. CX 516 had an extremely short halflife in humans, very low potency and failed to show any benefits in phase II studies. The compound did have a good safety profile, reducing concerns about the toxicity of excess glutamate. Cortex subsequently terminated clinical development of CX 516.

Patch-clamp studies were carried out with outside-out patches excised from pyramidal neurons in field CA1 of rats organotypic hippocampal slices. Concentration-response relations for the steady-state current of responses to 800-ms applications of 1 mM L-glutamate was determined using CX546 solutions (50-5000mkM). CX516 did not exceed 30% of the peak current, even at the near-saturating concentration of 5 mM.
