A series of xanomeline analogs were synthesized and evaluated for binding at the M1 muscarinic acetylcholine receptor (M1 receptor). Specifically, compounds that substitute the O-hexyl chain of xanomeline with polar, ionizable, or conformationally restricted moieties were assessed for their ability to bind to the M1 receptor in a wash-resistant manner (persistent binding). From our screen, several novel ligands that persistently bind to the M1 receptor with greater affinity than xanomeline were discovered. Results indicate that persistent binding may arise not only from hydrophobic interactions but also from ionic interactions with a secondary M1 receptor binding site. Herein, a qualitative model that accounts for both binding scenarios is proposed and applied to understand the structural basis to wash-resistant binding and long-acting effects of xanomeline-based compounds.

Inhibitors of platelet-fibrinogen binding offer an opportunity to interrupt the final, common pathway for platelet aggregation.Small molecule inhibitors of the platelet fibrinogen receptor GPIIb/IIIa were prepared and evaluated for their ability to prevent platelet aggregation.Compound 23m (L-700, 462/MK-383) inhibited in vitro platelet aggregation with an IC50 of 9 nM and demonstrated a selectivity of >24000-fold between platelet and human umbilical vein endothelial cell fibrinogen receptors.Dose-dependent inhibition of ex vivo platelet aggregation induced by ADP was achieved with iv infusions 0.1-10 μg/kg/min of 23m in anesthetized dogs, with 10 μg/kg/min completely inhibiting platelet aggregation during the entire 6 h infusion protocol.Platelet aggregatability returned rapidly after the termination of the 23m infusions.These features suggest that 23m may be useful in the treatment of arterial occlusive disorders.
