Summary and Final Comments. In this study, we have identified
three sets of biaoctive compounds based on the tricyclic core of
the Stemona alkaloid skeleton shown in Fig. 6. These compounds
vary in their degrees of added structural complexity from a
simple amide reduction (6{10}) to a greater than twofold increase
of the molecular weight via an isocyanide MCR (14{26}).
Each of these compounds has provided potent binding compounds
that may be viewed as lead structures for further development.
Moreover, we identified a particular chemical feature
consistent with activity (a basic nitrogen atom), which suggested
a scaffold-hopping maneuver that resulted in unique compounds
with exquisite potency and selectivity against the Sig-Rs.
