从Leucetta和Clathrina海绵中分离出的含有多取代的2-氨基咪唑的一些代表性天然产物的全合成进行了描述。这些合成利用了4,5-二碘咪唑的位点特异性间位反应,从而合成了三种不同类型的Leucetta衍生的天然产物。通过MTT生长测定法测定这些天然产物以及沿着几种前体在MCF 7细胞中的细胞毒性。为了比较的目的,包括了一系列含萘咪唑的家族成员。
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.
