  Total Synthesis of Natural and Unnatural Lamellarins with Saturated and Unsaturated D-Rings

  摘要：

  Twenty-eight natural and unnatural lamellarins with either a saturated or an unsaturated D-ring were synthesized according to our developed synthetic route. The key step involved the Michael addition/ring closure (Mi-RC) of the benzyldihydroisoquinoline and alpha-nitrocinnamate derivatives, which provided the 2-carboethoxypyrrole intermediates in moderate to good yields (up to 78% yield). Subsequent hydrogenolysis/lactonization furnished lamellarins with a saturated D-ring in excellent yields (up to 93% yield). DDQ oxidation of the saturated lamellarin acetates led directly to the corresponding unsaturated analogues in 54-95% yield. In addition, only two steps in our developed strategy require column chromatography.

• New lamellarin alkaloids from an unidentified ascidian from the Arabian Sea

  An unidentified ascidian from the Arabian Sea contained nine new alkaloids of the lamellarin class together with lamellarin N. The structures of the 20-sulfate derivatives of lamellarins T, U, V, and Y (1–4) and lamellarins T - X (5–9) were identified by interpretation of spectroscopic data. This is the first report of lamellarin sulfates.

• Synthesis, Resolution, and Biological Evaluation of Atropisomeric (a<i>R</i>)- and (a<i>S</i>)-16-Methyllamellarins N: Unique Effects of the Axial Chirality on the Selectivity of Protein Kinases Inhibition

  The total synthesis of the optically active (aR)- and (aS)-16-methyllamellarins N (3a and 3b) was achieved via resolution on HPLC chiral stationary phase. The kinase inhibitory activities of both enantiomers were evaluated on eight protein Icinases relevant to cancer and neurodegenerative diseases (CDKI/cyclin B, CDK2/cyclin A, CDK5/p25, GSK-3 alpha/beta, PIM1, DYRK1A, CLIO, and CK1). Isomer (aR)-3b exhibited potent but nonselective inhibition on all protein kinases except CK1, while (aS)-3a selectively inhibited only GSK-3 alpha/beta, PIM1, and DYRKIA. The different inhibition profiles of (aS)-3a and (aR)-3b were elucidated by docking simulation studies. Although parental lamellarin N (2) inhibited the action of topoisomerase I, both (aS)-3a and (aR)-3b showed no inhibition of this enzyme. The phenotypic scytotoxic activities of 2, (aS)-3a, and (aR)-3b on three cancer cell lines (HeLa, SH-SYSY, and IMR32) changed according to their topoisomerase I and protein kinase inhibitory activities.
