  An efficient synthesis of LipidGreen and its derivatives via microwave assisted reaction and their live lipid imaging in zebrafish

  摘要：

  We have developed an efficient synthesis of LipidGreen. The conversion is achieved by selective methylation with trimethylsilyldiazomethane, selective deprotection by BBr3 and an improved microwave-assisted C-allylation procedure. Using this route, we have synthesized novel LipidGreen derivatives, and evaluated their live imaging abilities in zebrafish. In this series, Compound 7 is the most active, which is at least 10 fold more potent than LipidGreen. (C) 2013 Elsevier Ltd. All rights reserved.

  A new small molecule probe for in vivolipid imaging, LipidGreen (compound 5), was developed. LipidGreen stained lipid droplets in 3T3L1 cell lines and fat deposits in zebrafish without apparent toxicity up to 100 μM. The utility of LipidGreen as a drug screening platform for fat regulation was also demonstrated in live zebrafish.

  一种新的小分子探针用于体内脂质成像，LipidGreen（化合物5）被开发出来。LipidGreen能够在3T3L1细胞系中染色脂肪滴，并在斑马鱼中染色脂肪沉积，最高浓度可达100 μM而没有明显的毒性。LipidGreen作为脂肪调节药物筛选平台的功能也在活体斑马鱼中得到了验证。
