| abstract |
A highly convergent biomimetic synthesis of a complex polycyclic scaffold has been successfully implemented. From these efforts, compounds having a structure of Formula (I) or a pharmaceutically acceptable salt, tautomer or stereoisomer thereof, wherein R 1 -R 8 and m, n, r, s, t, and u are as defined herein, is provided. Methods of making such compounds are also disclosed as are methods for the treatment of cancer, various infectious diseases, and abnormal cardiovascular function. |
