We describe a large scale synthesis of secramine A. Consistent with its ability to inhibit activation of the small GTPase Cdc42, we find that secramine A inhibits cell spreading, a process previously shown to be Cdc42-dependent.
The present invention provides novel alkaloid compounds and collections of these compounds, and provides methods for the synthesis of these compounds using biomimetic synthetic strategies. Additionally, the present invention provides pharmaceutical compositions and methods for treating disorders such as bacterial infections, proliferative diseases, and reproductive disorders, to name a few.

diversity-oriented synthesis to construct a library based on a natural product, galanthamine (2, Figure 1), with the goal of discovering molecules that exhibit biological effects beyond those previously associated with the natural product. Although 2 is a potent acetylcholinesterase inhibitor, 8 our aim was not to improve this activity. Galanthamine was selected because it offered a range of functionality
