CX-546 is an ampakine drug developed by Cortex Pharmaceuticals.
It has been proposed as a treatment for schizophrenia.[1] CX-546 was the second drug of note to come out of the Cortex research program, after CX-516, but while it was an improvement over its predecessor in some respects, it still has problems with limited oral bioavailability.
However, CX-546 still represented a significant advance that led on to the development of newer compounds such as CX-614 and CX-717 with superior properties over the earlier drugs. CX-546 itself has been investigated for other applications, and most notably has been found to show significant efficacy in reversing the respiratory depression produced by sedative drugs such as opioids and barbiturates.[2]
No effective respiratory stimulants are currently marketed for this application, with CX-546 being only the third drug discovered (after BIMU-8 and BW373U86) that effectively relieves the respiratory depression induced by fentanyl without reducing the analgesic effects. CX-546 could be developed for this purpose, although it is more likely that Cortex will use newer and more potent analogues such as CX-1739 or CX-1763, which are likely to be more suitable for commercial development.[citation needed]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
