7-HYDROXYFLAVONE Chemical Properties,Usage,Production

Synthesis

Acetylation of resorcinol acetic acid yields 2,4-dihydroxyacetophenone, which is then subjected to benzoylation and transposition to obtain (2-hydroxy-4-benzoyloxy)benzoylacetophenone. 7-hydroxyflavone was obtained by further cyclization reaction in a mixture of acetic acid and hydrochloric acid at 103° C for 7 h.

Chemical Properties

off-white crystals

Uses

antifungal, analgesic

Uses

Reactant:

Acting as a biologically valuable acceptor in O-glycosidation reactions
Involved in synthesis of fully phosphorylated flavones for use as pancreatic cholesterol esterase inhibitors
For O-methylation with di-Me carbonate
Linked by a polymethylene chain for synthesis of α1-adrenoceptor antagonists
Involved in Baylis-Hillman reactions
Involved in phase-transfer catalyzed glucosylation for synthesis of glucosylated flavonoids

Definition

ChEBI: 7-hydroxyflavone is a hydroxyflavonoid in which the flavone nucleus is substituted at position 7 by a hydroxy group.

Synthesis Reference(s)

Tetrahedron Letters, 31, p. 6497, 1990 DOI: 10.1016/S0040-4039(00)97100-4

Biological Activity

7-Hydroxyflavone is a flavonoid isolated from M. indica with anti-inflammatory properties. It protects renal cells from nicotine (NIC)-induced cytotoxicity through the ERK/Nrf2/HO-1 pathway.
