Provided in the present disclosure are peptidic imaging probes (radiotracers) useful for the non- invasive detection of cancers and other conditions or disorders characterized by expression or over- expression of the bradykinin B1 (B1R) receptor. The present peptidic probes may, for example, be 18F-AmBF3-B9858 or 18F-AmBF3-B9958. The imaging probes of the disclosure are peptidic compositions, bind with high affinity and selectivity to the B1R and are 18F- labelled and suitable for imaging procedures such as positron emission tomography (PET). These agents can be used for the early diagnosis, staging and prognosis of B1R-positive cancers or other disease conditions. The B1R imaging probes can also be used to identify B1R-positive cancer patients who may benefit from emerging B1R-targeted therapies.
本公开提供了一种肽成像探针(放射性示踪剂),用于非侵入性检测癌症和其他表达或过表达
缓激肽B1(B1R)受体的病情或疾病。本肽探针可以是18F-AmBF3-
B9858或18F-AmBF3-
B9958等。本公开的成像探针是肽组成物,具有高亲和力和选择性结合B1R,并且是18F标记的,适用于正电子发射断层扫描(PET)等成像程序。这些试剂可以用于B1R阳性癌症或其他疾病情况的早期诊断、分期和预后。B1R成像探针还可以用于识别可能从新兴的B1R靶向治疗中受益的B1R阳性癌症患者。
