It is suggested that in chronic (i.e., therapeutic) application, S-(+)-mecamylamine might be preferable to R-(-)-micylamine in terms of equilibrium inactivation of neuronal receptors with decreased side effects associated with muscle-type receptors.

The characterization of prolonged bursts of single-channel currents that occur with PNU-120596 provide a remarkable contrast to the behavior of the channels in the absence of the PAM, which shows a 100,000-fold increase in Popen compared with receptors in the nonpotentiated state.

The studies suggest that the efficacy of GTS-21 in primates may depend on a pro-drug function, and 4OH-G TS-21 was protective in both human and rat cell lines, although GTS -21 was effective only in the latter.

Despite reduced potentiation at body temperatures, use of type II positive allosteric modulators may put cells that naturally express high levels of α7 nAChRs, such as neurons in the hippocampus and hypothalamus, at risk.
