  Efficient Syntheses of the Marine Alkaloids Makaluvamine D and Discorhabdin C: The 4,6,7-Trimethoxyindole Approach

  摘要：

  A new and efficient synthesis of the tricyclic quinonimine 20 as its trifluoroacetate 23 has been developed starting from the commercially available 2,4,5-trimethoxybenzaldehyde and proceeding via the hitherto unknown 4,6,7-trimethoxyindole (7). Quinonimine 23 is the late stage key intermediate in several previously reported syntheses of the biologically active pyrrolo[4,3,2-de]-quinoline marine alkaloids discorhabdin C (1) and makaluvamine D (3).

  The present disclosure provides compounds based on the marine alkaloid makaluvamine. Described are compounds of the general formula (I) and (II). Also described are pharmaceutical compositions comprising one or more of the compounds of the general formula (I) and (II). The compounds and pharmaceutical compositions described inhibit the growth of several cancer lines, induce apoptosis and cell cycle arrest, display topoisomerase II inhibitory activity and modulate the activity and/or expression of key proteins involved in the regulation of cell growth. Methods of treatment and prevention using the compounds and pharmaceutical compositions described are also provided.
