The present invention is directed towards new 18F-folate radiopharmaceuticals, wherein the 18Fisotope is linked via a prosthetic group, more specifically via a prosthetic group having a saccharide group, such as acyclic mono-or oligosaccharide, preferably based on a pyranoside or furanoside, which is covalently linked to the glutamate portion of a folateor 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,更具体地通过一个具有糖苷基团的假体基团连接,例如非环式
单糖或
寡糖,最好基于
吡喃糖苷或
呋喃糖苷,它与叶酸或其衍
生物的谷
氨酸部分共价连接,以及它们的制备方法,以及它们在癌症、炎症和自身免疫疾病的诊断和监测以及治疗中的应用。
