Quinizarin  (Synonyms: 1,4-二羟基蒽醌; 1,4-Dihydroxyanthraquinone)

Quinizarin (1,4-Dihydroxyanthraquinone), a part of the anticancer agents such as Doxorubicin, Daunorubicin, and Adriamycin, interacts with DNA by intercalating mode (K_d=86.1 μM). Quinizarin is used as a fungicide and pesticide chemical and has shown the ability to inhibit tumor cell growth^[1][2].

1,4-Dihydroxyanthraquinone (1,4-DHAQ, a fluorophore) doped cellulose (CL) (denoted as 1,4-DHAQ@CL) microporous nanofiber film has been achieved via simple electrospinning and subsequent deacetylating, and used for highly sensitive and selective fluorescence detection of Cu(2+) in aqueous solution^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
