2-Hydroxy-3-[(2-hydroxy-4-methoxy-6-propylbenzoyl)oxy]-4-methoxy-6-propylbenzoic acid

Definition

ChEBI: Sekikaic acid is a carbonyl compound.

Biological Activity

Sekikaic acid is a phenolic lichen metabolite that has been found in H. obscurata and has diverse biological activities.1,2,3 It scavenges superoxide and DPPH radicals in cell-free assays when used at a concentration of 0.5 μM.1 Sekikaic acid is active against the rg recombinant strain of respiratory syncytial virus (RSV; IC50 = 5.69 μg/ml).2 It inhibits the protein-protein interaction between mixed lineage leukemia 1 (MLL1) and the GACKIX domain of CREB-binding protein (CBP; IC50 = 34 μM).3
