Antiproliferative activity was measured on three human cancer cell lines (A549, MCF-7, HBL-100), to show which of the structural elements of goniothalamins is mandatory for cytotoxicity. We found that the configuration of the stereogenic centre of the δ-lactone plays an important role for cytotoxicity. In our studies only (R)-configured goniothalamins showed antiproliferative activity, whereby (R)-configuration
含有环丙烷基团的取代的鸟胆素可以高效地制备,并具有很高的选择性。在三种人类癌细胞系(A549,MCF-7,HBL-100)上测定了抗增殖活性,以显示淋菌素的哪些结构元素对细胞毒性具有强制性。我们发现,δ-内酯的立体中心的构型在细胞毒性中起重要作用。在我们的研究中,只有(R)构型的鞘脂素显示出抗增殖活性,其中(R)构型与天然的Goniothalamin(R)-1一致。另外,δ-内酯需要不饱和,而我们的结果表明乙烯基双键对于细胞毒性不是强制性的。此外,通过双重的体外和体内策略,我们确定了化合物对酵母蛋白Pdr5的抑制作用。
