| Cmpd | X | M1 EC50 (μM)a | %CCh Maxa | D2 IC50 (μM)a |
| 15a | 4-F | >10 | 46 | 1.1 |

EC50s, % CCh maximum (measures M1 activation relative to 100% CCh response) and IC50s are the mean of at least three independent determinations. All analogues in this Table are selective for M1 (>30 μM vs. M2–M5).
