facilitated the synthesis of a variety of fluorophore-labelled probes, of which dansyl analogue 20 exhibited biological activity, providing a tool for mechanism of action and cellular localization studies. An alternative probe design was also exemplified, whereby a bioactive alkyne-terminated analogue (24) was found to undergo Huisgen 1,3-dipolar cycloaddition ‘click’ reactions with fluorescent azides, enabling
已经发现细胞毒性海洋生物碱discorhabdin C的半合成的N -13烷基化类似物对肿瘤细胞系具有与天然产物相当的细胞毒性。乙二胺接头的掺入促进了多种荧光团标记的探针的合成,其中丹磺酰类似物20表现出生物活性,为作用机理和细胞定位研究提供了工具。还举例说明了另一种探针设计,据此发现具有生物活性的炔烃封端的类似物(24)与荧光叠氮化物进行了Huisgen 1,3-偶极环加成“点击”反应,从而使研究针对基于活性的蛋白质谱分析成为可能。
