 68GA labeled glerealis, ox, HBEDCC, 68GA, GAPSMA HBEDCC, is a successful novel PSMA inhibitor radio tracer that has recently demonstrated its suitability in individual first-in-man studies. And the radiometall keelator HBEDCC used in this molecule contributes intrinsically to the PSMA binding of the glerealis, ox, pharmacophore.
