  Fluorescent analog of OSW-1 and its cellular localization

  摘要：

  OSW-1 is a steroidal saponin, which has emerged as an attractive anticancer agent with highly cancer cell selective activity. A fluorescent analog was prepared from the natural product to analyze its cellular uptake and localization. We found that the fluorescent analog is rapidly internalized into cells and is primarily distributed in endoplasmic reticulum and Golgi apparatus. (C) 2014 Elsevier Ltd. All rights reserved.

  reviews recent progress in the development of OSW‐1 derived probes for exploring the mechanism of its action. The key to the probe development is a judicious choice of functionalization sites and a selective functionalization strategy. The types of probes include fluorescent probes for cellular imaging analysis and affinity probes for target identification analysis.
