DNA Intercalation Overview
DNA intercalation refers to the process by which molecules, typically planar aromatic compounds, insert themselves between the stacked base pairs of double-stranded DNA. This disrupts normal DNA structure and function, inhibiting replication and transcription. Intercalators are used in chemotherapy, molecular probes, and antisense technology. The strength and specificity of binding depend on the intercalator's planarity, charge, size, and geometry. Examples include doxorubicin, ethidium bromide, and proflavine.
Mechanism of Action
Non-covalent insertion between stacked base pairs of DNA, leading to structural changes and disruption of replication and transcription.
Biological Functions
Disruption of replication
Disruption of transcription
Nucleic acid staining
Disease Associations
Cancer
Infection
Safety Considerations
- Potential for off-target effects due to non-specific DNA binding.
- Toxicity associated with chemotherapeutic intercalators.
- Potential for mutagenicity.
Interacting Drugs
