Its research centered on ampakines, a class of compounds designed to modulate AMPA receptors and potentially improve respiratory function, cognition, and other neurological processes. The company developed several investigational drug candidates, including CX717 and CX1739. These compounds were studied for potential applications such as respiratory depression associated with opioid use, obstructive sleep apnea, attention-related disorders, and other neurological conditions. The products remained experimental and were not broadly commercialized as approved medicines. Cortex Pharmaceuticals subsequently changed its name to RespireRx Pharmaceuticals, Inc., and became associated with the OTC Markets symbol RSPI. Publicly available information about its current operations, leadership, geographic reach, and commercial activities is limited.AI Generated. May Contain Errors.
