Biological Activity

Quinizarin (1,4-dihydroxyanthraquinone) is an anthraquinone derivative that acts as a DNA intercalating agent and structural core of anthracycline anticancer compounds. By intercalating into DNA, it disrupts nucleic acid synthesis and suppresses downstream DNA replication and transcription pathways. This inhibition destabilizes genomic integrity and reduces tumor cell growth and proliferation across various cancer cell lines. [1][2]
