Ispronicline (TC-1734, AZD-3480) is an experimental drug which acts as a partial agonist at neural nicotinic acetylcholine receptors. It progressed to phase II clinical trials for the treatment of dementia and Alzheimer's disease, but is no longer under development.[1]
It has also progressed to phase II as a potential treatment for ADHD. With dosages of 50 mg/day showing a significant improvement in ADHD symptoms[2][3]
Ispronicline is subtype-selective, binding primarily to the α4β2 subtype. It has antidepressant, nootropic and neuroprotective effects.[medical citation needed]
Early stage clinical trials showed that ispronicline was well tolerated, with the main side effects being dizziness and headache.[4][5][6][7][8] However, mid-stage clinical trials failed to show sufficient efficacy to continue development as a pharmaceutical drug.[1]

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.
