0.03 µM, 8.95 ± 0.17 µM respectively. Further, the target compound 7q was radiolabeled with fluorine-18 [18F] to be used as a novel PET radiotracer for imaging of tumors via targeting galectin-1, using appropriate reaction conditions in the GE Tracer-lab FX2N synthesis module. The purification of the [18F] radiolabeled compound [18F]-7q was successfully achieved with 60% ethanol. The radiochemical purity
在本研究中,已经合成了一系列新的4、7-二取代香豆素衍生物(7a-y)作为靶向细胞凋亡诱导剂的半乳凝素-1,并评估了它们对一组选定的人类癌细胞系的体外细胞毒性潜力,使用MTT分析法检测布雷斯特(MCF7),卵巢(SKOV3),前列腺(PC-3和DU145)和正常胚胎肾(HEK293T)细胞。大多数化合物对处理过的癌细胞系表现出有效的生长抑制作用,IC50范围为10-30 µM。化合物7q对前列腺癌(PC-3和DU145)细胞系表现出显着的生长抑制作用,IC50值分别为7.45±0.03 µM,8.95±0.17 µM。此外,目标化合物7q用氟18 [18F]进行了放射性标记,用作新型PET放射性示踪剂,可通过靶向半乳糖凝集素1来成像肿瘤,在GE Tracer-lab FX2N合成模块中使用适当的反应条件。用60%乙醇成功完成[18F]放射性标记化合物[18F] -7q的纯化。通过HPLC,
