Title:
RADIOACTIVE METAL COMPLEX AND METHOD FOR PRODUCING SAME, AND RADIOACTIVE METAL SCAVENGER
Document Type and Number:
WIPO Patent Application WO/2023/013589
Kind Code:
A1
Abstract:
Disclosed is a radioactive metal complex. Said radioactive metal complex has a radioactive metal element and a ligand derived from a compound represented by formula (1). The radioactive metal element is 89Zr or 225Ac. [In formula (1), n is 1-3. Q1, Q2, Q3 and Q4 represent groups selected from group A or the like, and at least three of said groups are groups selected from group A. Group A is a group comprising groups represented by formula (A1) or the like. (R1-R3 represent hydrogen atoms or the like.) Z1, Z2, Z3 and Z4 each represent a divalent linking group or the like. R represents a divalent linking group. However, when n is 1 and Q1, Q2, Q3 and Q4 are all groups represented by formula (A1), R is a hydrocarbylene group or the like.]
