摘要

The interest for (alpha)-particle emitters in internal radiotherapy is increasing due to improved conjugation chemistry. Experimental work has concentrated on (sup 211)At and (sup 212)Bi since these to nuclides have radiochemical and physical properties suitable for medical application. In this report it is demonstrated that biologically active (sup 211)At-labelled compounds can be prepared within a relatively short time allowing utilization of this 7.2 h (alpha)-particle. It is further shown that (sup 211)At-TP-3 treatment of human osteosarcoma in vitro gives promising therapeutic ratios. 76 refs., 5 figs., 3 tabs. (Atomindex citation 28:008322)
