Quinone methides (QMs) are electrophilic intermediates that can be generated in vivo to alkylate DNA and function as anti-cancer drugs. Previously, DNA-QM conjugates have shown the ability to selectively deliver a QM to specific sequences of DNA. Peptide nucleic acids (PNAs) conjugates of QM are now being developed since PNA binds DNA with higher affinity than natural DNA. Synthesis of PNA oligomers and conjugation of the PNA…
