An improved total synthesis of spermatinamine, an inhibitor of isoprenylcysteine carboxy methyltransferase
摘要:
An improved total synthesis of spermatinamine, an inhibitor of the anticancer target, isoprenylcysteine carboxy methyltransferase (Icmt) was accomplished from the commercially available 3,4-dibromo-4-hydroxybenzaldehyde via a high yielding reaction sequence in an overall yield of 31%.

Versatile Routes to Marine Sponge Metabolites through Benzylidene Rhodanines
摘要:
The first total synthesis of the marine natural products Psammaplin C and Tokaradine A is described. Benzylidene rhodanines were utilized as versatile intermediates toward the synthesis of seven brominated marine sponge metabolites through the optimization of protection group strategies. Spermatinamine demonstrated good inhibition of all cancer cell lines tested, in particular the leukemia K562 and colon cancer HT29 cell lines.
