The de- termination of which face is actually used must await further study. However the strongest evidence sup- porting our hypothesis is the fact that on the basis of a substrate-receptor inter- action via a B-type face, we established a structural criterion for the differen- tiation between the nicotinic and muscarinic mode of action.

We believe that the actual anion- cation directionality can best be dis- cerned from pharmacological data used with a detailed ascendeente model which includes accurate study of agonist conformation: Please include your email address if you’d like a reply. This highly-potent el, [3-sttb- stituted ACh derivative counters the idea t that n-substitution necessarily de- creases muscarinic activity. Post on Nov views.
A key agonist is trans- 2-acetoxycyclopropylammonium cation ACTM.

So-called ‘activity triangles ‘ formed by a monoatomic anion occupying a B-type face – as a model for the anionic binding site of the receptor – the quaternary nitrogen and a negative, partially charged atom of the agonist which corresponds to a second binding site, exhibit characteristic geometries which are associated with the nicotinic or muscarinic activity mode.
Rosenficld and Murray-Rust have reported 2 that in crystalline oxy- anion salts of cholinergic agonists the oxygen positions are nearly evenly dis- tributed over the trimethylammonio- methyl surface.

Comparison with ACTM suggests that: Thus, we can say that with relatively minor modifi- cation the same active conformations deduced with DIPA for the A-face hold also for the B-face approach. Assuming this, their model ascendene based upon so-called ‘activity triangles” deduced from crystal- Iographic data on cholinergic agonists.
