Abstract
[(η5-Cp)ReI(CO)3] was incorporated into the kinase inhibitor Opaganib®. The resulting bioorganometallic complex showed a similar anti-cancer activity to Opaganib® against PC-3 cancer cells. The IC50 value for the kinase SK2 is 30x higher than that of Opaganib®. The 99mTc homologue was synthesized, completing a matched-pair for molecular theranostics.
Replacing an adamantyl unit in the protein kinase inhibitor Opaganib® with an integrated [(η5-Cp)M(CO)3] (M = Re, 99mTc) unit retains the lead's bioactivity and yields a true matched-pair pharmacomimetic.![]()
