ChEBI: 3',4'-dihydroxyaurone is a hydroxyaurone that is aurone which is substituted by hydroxy groups at the 3' and 4' positions; major species at pH 7.3. It shows inhibitory activity against several isoforms of the histone deacetylase complex (HDAC). It has a role as an EC 3.5.1.98 (histone deacetylase) inhibitor. It is a hydroxyaurone and a member of catechols. It is functionally related to a 2',3,4-trihydroxy-trans-chalcone.

SKI V is a non-competitive, potent non-lipid sphingosine kinase (SPHK; SK) inhibitor with IC50 of 2 μM against GST-hSK. SKI V potently inhibits PI3K with IC50 of 6 μM for hPI3k. SKI V reduces the formation of the mitotic second messenger sphingosine-1-phosphate (S1P). SKI V induces apoptosis and has antitumor activity.
