intercalative การใช้
- In the case of ruthenium intercalators, the general synthesis consists of preparing intercalative ligands followed by their coupling to a ruthenium metal complex coordinated by specific ancillary ligands.
- Because of this, it is thought that most of the anti-cell growth function of ICZs comes from inhibition of various protein kinase groups and intercalative DNA binding.

- Studies have found that in REB-like structures, the imide function of the pyrrole segment acts to interact with Topoisomerase I, the main carbon backbone acts as an intercalative inhibitor, and the sugar moiety undergoes DNA groove binding.
- In contrast, the structurally similar o-AMSA differing in the position of the methoxy substituent group on the anilino-ring have little ability to poison topoisomerase II despite of its intercalative behavior, suggesting that intercalation of the molecule in itself is insufficient to trap topoisomerase II as a covalent complex on DNA.
- The general modes of action found in mammalian cells are inhibition of protein kinases, inhibition of eukaryotic DNA topoisomerase, and intercalative binding to DNA . The number of protein kinases thought to exist in the human genome exceeds six hundred, making a nanomolar inhibitor such as STA extremely useful for both treatment of various diseases and study of protein kinases in a variety of functions.
