Research Abstract

Lamellarins, a family of hexacyclic pyrrole alkaloids originally isolated from marine invertebrates, has promising anti-tumor activity. It is also reported that lamellarin alpha 20-sulfate inhibits HIV-1 integrase. In the present study, we investigated anti-tumor activity against HTLV-1 related leukemia cell lines and activity of integrase inhibition of HTLV-1 by using new synthesis of lamellarins. We focused on an agent No.5, a new synthetics from lamellarins, that showed potent anti-tumor activity against HTLV-1 related leukemia cell lines and ATL cells but no harm to PBMCs from healthy donors. Microarray analysis indicated that unique apoptosis-related genes were up-regulated by the No.5 agent. We still continue investigating the mechanisms of apoptotic pathways as well as function of integrase inhibition caused by a new synthetics from lamellarins.
