RADIOACTIVE HALOGEN LABELED COMPOUNDS OR SALTS THEREOF, AND PHARMACEUTICALS CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide: radioactive halogen labeled compounds which have high selectivity for aldosterone synthase (CYP11B2) over steroid 11β-hydroxylase (CYP11B1) and high accumulation selectivity in the adrenal gland compared to the surrounding organs; and diagnostic imaging agents containing the compounds.SOLUTION: The present invention provides radioactive halogen labeled compounds represented by the formula (1) in the figure, and diagnostic imaging agents containing the compounds. [In the formula, Ris a halogen atom or -(CH)OH, and Ris a halogen atom, a nitro group or a cyano group, provided that one of Rand Ris a radioactive halogen atom.]
