AVL-3288 is a type I selective positive allosteric modulator of α7 nACHRs. It represents a "first-in-class" drug for the treatment of cognitive deficits in CNS disorders such as schizophrenia and potentially other diseases of cognitive impairment such as Alzheimer’s disease and ADHD. AVL-3288 was successfully tested in representative animal models of cognitive dysfunction in schizophrenia, a disease where α7 nAChR function is impaired. To date, no specific treatments for cognitive deficits in schizophrenia exist and approved therapies do not satisfactorily improve cognition.
AVL-3288 is currently in human phase I trials.

Oral
AVL-3288 (0.1 nM to 10 uM) did not displace the binding
of the selective a7 nAChR antagonist 125I-labeled a-bungarotoxin
to rat brain tissue as quantified autoradiographically, nor did it directly evoke
currents in oocytes expressing human a7 nAChRs. It evoked positive modulation of EC5 currents induced by acetylcholine
(ACh), choline, and nicotine, with EC50 (and nH) values
for positive modulation of 0.7 +/- 0.2 uM (1.4+/- 0.9), 0.6 +/- 0.1
uM (1.2+/-0.3), and 0.5 +/- 0.1 uM (1.2+/-0.3), respectively.
A fixed concentration of AVL-3288 (1 uM) induced a leftward shift in the concentration–response
curve for ACh, resulting in an 2.7-fold reduction
in the EC50 values for ACh from 136 +/- 0.1 uM (control)
to 50 +/- 0.1 uM (in the presence of compound AVL-3288) and a slight
increase in nH values from 1.0 +/- 0.2 to 1.2 +/- 0.3, respectively
