| Outline of Final Research Achievements |
The fluorescent molecular probe possessing the C43-C67 part of amphidinol 3 (AM3) was synthesized. Although liposomes were incubated with the molecular probe and observed by using fluorescence microscope, no fluorescent was detected. These results suggested that the C43-C67 part of AM3 was not enough to interact with lipid membrane and useful information to design new molecule possessing high affinity with lipid membranes.
As a part of the structure-activity relationship studies to elucidate structure requirements for eliciting antifungal activity, a truncated analog corresponding to the C21-C39/C52-C67 section of AM3 was synthesized by using Suzuki-Miyaura coupling and Julia-Kocienski olefination as key steps. Although the biological activity of the analog was evaluated, it elicited no antifungal activity. These results that the two tetrahydropyran rings of AM3 are necessary to elicit antifungal activity.
