  Detection of apoptosis by PET/CT with the diethyl ester of [18F]ML-10 and fluorescence imaging with a dansyl analogue

  摘要：

  The diethyl ester of [F-18]ML-10 is a small molecule apoptotic PET probe for cancer studies. Here we report a novel multi-step synthesis of the diethyl ester of ML-10 in excellent yields via fluorination using Xtal-Fluor-E. In addition, a one-pot radiosynthesis of the diethyl ester of [F-18]ML-10 from nucleophilic [F-18]fluoride was completed in 23% radiochemical yield (decay corrected). The radiochemical purity of the product was >= 99%. The diethyl ester of [F-18]ML-10 was used in vivo to detect apoptosis in the testes of mice. In parallel studies, the dansyl-ML-10 diethyl ester was prepared and used to detect apoptotic cells in an in vitro cell based assay. (C) 2013 Elsevier Ltd. All rights reserved.

  The present invention relates to a solid precursor in the form of an organic salt, the solid precursor having a solid support, a method for manufacturing same, and an application thereof. The solid precursor of the present invention enables omission of the [ 18 F]fluoride refining process using additional cartridge, and the use of excessive phase-transfer catalyst, and can easily remove remaining substance after reaction through the solid support inside the precursor. The solid precursor of the present invention is very appropriate for an automated synthesis device as an all-in-one system that can carry out overall process of [ 18 F]fluorosis reaction, when used by charging in a cartridge.

  本发明涉及一种有机盐形式的固体前体，该固体前体具有固体支撑物，以及制造该固体前体的方法和其应用。本发明的固体前体使得可以省略使用额外的装置进行[ 18 F]氟化物精制过程，并且可以使用过量的相转移催化剂，并且可以通过前体内部的固体支撑物轻松去除反应后剩余物质。本发明的固体前体非常适用于作为一种全自动合成装置，可以通过在装置中充电使用，执行[ 18 F]氟化反应的整个过程。
