1,4-Diamino anthraquinone Chemical Properties,Uses,Production

Chemical Properties

Violet powder

Uses

As an anthraquinone derivative, 1,4-Diamino anthraquinone is a potent and selective protein kinase CK1 delta inhibitor. Studies suggest that it has potential solar cell applications. 1,4-Diamino anthraquinone can be used in studies as a potential competitive non-peptidic inhibitor of HIV-1 proteinase.

Purification Methods

Purify the anthraquinone by thin-layer chromatography on silica gel using toluene/acetone (9:1) as eluent. The main band is scraped off and extracted with MeOH. The solvent is evaporated, and the quinone is dried in a drying pistol [Land et al. J Chem Soc, Faraday Trans 1 72 2091 1976]. It crystallises from EtOH (m 269o) in dark violet crystals. Store it in sealed ampoules in the dark. [Beilstein 14 H 197, 14 II 113, 14 III 437, 14 IV 458.]
