We labeled the compounds targeting prostate specific membrane antigen (PSMA) with At and Ac. PSMA is a molecule that has attracted attention as a theranostic target for prostate cancer, and several targeted radioligands have already shown therapeutic effects in patients. The results showed that At, which has a much shorter half-life, is no less cytotoxic than Ac. In At labeling, our group has also developed an original method (Shirakami Reaction). We have succeeded in obtaining a highly purified labeled product in a short timeframe using this method.
