Outline of Final Research Achievements |
The bisacetylenic alcohols have been discovered from a marine sponge (Callyspongia sp.) at Iriomote-island, Okinawa Prefecture. The structure-activity relationship using various synthetic derivatives revealed the unique phenomenon that cell proliferation inhibitory activity of each enantiomer differs by 4 times. For expression of the cell proliferation inhibitory activity of bisacetylenic alcohols, "1-yn-3-ol" at both ends of the molecule is essential for the activity, and its cell growth inhibition mechanism is different from stabilization of the microtubule in the cytoplasm. The identification of the target molecule by immobilizing magnetic beads of bisacetylenic alcohol was planned. Currently, NHS-beads having "1-yn-3-ol" in one of the alkyl chain lengths 20 has been synthesized, and future target molecule will be identified using this molecular probe.
