Identification of pheromone receptors plays a central role for uncovering signaling pathways that underlie chemical communication in animals. Here, we describe the synthesis and bioactivity of photoaffinity probes for the ascaroside ascr#8, a sex-pheromone of the model nematode, Caenorhabditis elegans. Structure–activity studies guided incorporation of alkyne- and diazirine-moieties and revealed that
small molecule tagging (MSMT) is a promising approach that easily converts bioactive compounds into affinity-based probes (AfBPs) for proteomic studies. In this work, seven bioactive compounds targeting diversified protein classes were installed with “minimalist” linkers through common reactions to generate the corresponding AfBPs. These probes were evaluated for cell-based protein profiling and target
“极简主义”小分子标签(MSMT)是一种有前途的方法,可以轻松地将生物活性化合物转换为基于蛋白质组学研究的基于亲和力的探针(A f BPs)。在这项工作中,通过共同反应安装了具有“极简主义”接头的,针对多样化蛋白质类别的七个生物活性化合物,以生成相应的A f BP。对这些探针进行了基于细胞的蛋白质谱分析和靶标验证。其中,来自恩替司他的探针EN和喜树碱的探针CA被进一步用于细胞成像和基于SILAC的大规模目标识别。我们的广泛研究表明,“极简主义”小分子标记方法可以扩展到不同类别的生物活性化合物,以修饰为A f BP,作为蛋白质组学和细胞成像的双重功能工具。
