Analogs of cytochalasin B are used as radiopharmaceuticals to provide an image for the nuclear imaging of glucose transport across cell membranes. Like cytochalasin B, the analogs bind specifically to glucose transport protein, and in doing so, serve as markers indicating the amount of glucose transport protein present on the surfaces of cells. The analogs differ from cytochalasin B by the inclusion of a radionuclide in the region of the terminal phenyl group on cytochalasin B, where the radionuclide does not interfere with the binding specificity of the analog. Disclosed herein are such analogs as well as analogs with which readily accept radionuclides at the desired location on the structure, either by conjugation or substitution.
细胞毒霉素B的类似物被用作放射性药物,用于提供细胞膜上

葡萄糖转运蛋白,从而作为标记物指示细胞表面上存在的
葡萄糖转运蛋白的数量。这些类似物与细胞毒霉素B的区别在于,在细胞毒霉素B末端苯基区域包含放射性核素,其中放射性核素不会干扰类似物的结合特异性。本文介绍了这些类似物以及可通过共轭或取代在所需位置上容易接受放射性核素的类似物。
