The total synthesis of a number of representative natural products isolated from Leucetta and Clathrina sponges containing a polysubstituted 2-aminoimidazole are described. These syntheses take advantage of the site specific metallation reactions of 4,5-diiodoimidazoles resulting in the syntheses of three different classes of Leucetta derived natural products. The cytotoxicities of these natural products, along with several precursors in MCF7 cells were determined through an MTT growth assay. For comparative purposes a series of naphthimidazole-containing family members are included.
描述了从含有多取代2-氨基咪唑的白海绵属和网格海绵属海绵中分离出的多种代表性天然产物的全合成。这些合成利用了4,5-二碘咪唑的位点特异性金属化反应，从而合成了三类不同的源自白海绵属的天然产物。通过MTT生长试验测定了这些天然产物以及MCF7细胞中的几种前体的细胞毒性。为了进行比较，还包括了一系列含萘并咪唑的家族成员。
