| Outline of Final Research Achievements |
Schulzeine and Penasulfate, which are marine-derived natural products and have strong a-glucosidase inhibition activity, were synthesized using new synthetic methods developed by our group. The bioactivity or these compounds were measured using a-glucosidase assay kit, and it was found that these are more active than commercially available a-glucosidase inhibitors. These compounds consist of a heterocyclic moiety and a long fatty acid moiety, and these are joined with an amide bond. Thus, the project was continued to synthesize hybridized compounds, which exchange the combination of these two parts.
In the synthesis of SMTP-7, we tried hard to complete the total synthesis, and found that a few more steps are necessary for the completion of the synthesis.
