Radiohalogenated thienylethylamine derivatives for evaluating local cerebral blood flow

Patent Application · Thu Dec 22 00:00:00 EST 1988

OSTI ID:5516699

Goodman, M M; Knapp, Jr, F F

An improved method of chemical synthesis of radiohalogenated thienylethylamine derivatives useful in brain imaging is described. These 5-halo-thiophene-2-isopropyl amines readily cross the blood- brain barrier and are retained in the brain for a sufficient length of time to allow evaluation of regional blood flow in the cerebrum. The advantages of the invention include a simpler synthesis route and a final compound which is less diluted with nonradioactive halogen. Use of this invention will allow clearer radioimaging or lower radiation doses to the patient, depending on the objective. 2 figs., 1 tab. (MHB)
