    Synthesis and Biological Evaluation of Purpurealidin E-Derived Marine Sponge Metabolites: Aplysamine-2, Aplyzanzine A, and Suberedamines A and B
    摘要:
    Five purpurealidin-derived marine secondary sponge metabolies have been synthesized through the carbodiimide coupling of an appropriate bromotyrosine unit. The structure elucidations have been confirmed through direct comparison with spectroscopic data of isolated natural products. Aplyzanzine A has been shown to be the most active product against a broad bacterial and fungal screen, demonstrating MIC values 2 to 4 times lower than the other metabolites in this study. Compounds 2, 3, 4a, and 5-7 exhibit a modest inhibition against slow growing mycobacteria (MIC 25-50 mu g/mL), including Mycobacterium tuberculosis. iso-Anomoian A and suberedamine B showed antitumor activity in the NCI-DTP60 cell line screen at single-digit micromolar concentrations, with iso-anomoian A inhibiting 53 cell lines. These molecules present novel scaffolds for further optimization.

    oxime (8) in high yield. Controlled bromination of the aromatic ring gave the monobromo oxime (9), the dibromo oxime (10), or the spiroisoxazoline (11) depending upon reaction conditions. Synthesis of the known metabolite verongamine (15) was achieved by oxidation of O-methyl bromotyrosine methyl ester and amidation of the resulting oxime ester (14) with histamine.
