The present invention is directed towards new
18
F-folate radiopharmaceuticals, wherein the
18
F isotope is linked via a prosthetic group, more specifically via a prosthetic group having a saccharide group, such as a cyclic mono- or oligosaccharide, preferably based on a pyranoside or furanoside, which is covalently linked to the glutamate portion of a folate or derivative thereof, a method of their preparation, as well as their use in diagnosis and monitoring of cancer and inflammatory and autoimmune diseases and therapy thereof.
本发明涉及新的18F-叶酸类放射性药物,其中18F同位素通过一个假体基团连接,更具体地说是通过一个带有糖苷基团的假体基团连接,比如基于
吡喃苷或
呋喃苷的环状
单糖或
寡糖,该基团共价连接到叶酸或其衍
生物的谷
氨酸部分,以及它们的制备方法,以及在癌症、炎症性和自身免疫性疾病的诊断和监测以及治疗中的使用。
