Stictic acid
Based on 1 Customer Validation
Stictic acid is a Depsidone. Stictic acid is found in the edible lichens Lobaria pindarensis and Lobaria pulmonaria. Stictic acid inhibits LPS/Aβ42-induced mRNA expression of iNOS, IL-1β, TNF-α, and IL-6, and decreases LPS-induced COX-2 protein expression. Stictic acid inhibits Aβ42 fibril formation and aggregation. Stictic acid scavenges superoxide anions. Stictic acid exhibits anticancer activity against colon adenocarcinoma. Stictic acid is used in research on Alzheimer's disease and colon adenocarcinoma.

In Vitro
Stictic acid (30 μM; pretreatment for 3 h before LPS stimulation) completely inhibits LPS-induced mRNA expression of IL-6, IL-1β, iNOS, and TNF-α in RAW264.7 cells[1].
Stictic acid (30 μM; pretreatment for 3 h before LPS stimulation) inhibits LPS-induced mRNA expression of IL-6, IL-1β, iNOS, and TNF-α in BV2 cells[1].
Stictic acid (30 μM; pretreated for 3 h before LPS stimulation) significantly reduces COX-2 protein expression in LPS-induced RAW264.7 cells[1].
Stictic acid (30 μM; pretreatment for 3 h before LPS stimulation) inhibits LPS-induced COX-2 protein expression in BV2 cells[1].
Stictic acid (30 μM; pretreatment for 3 h before LPS stimulation) inhibits LPS-induced phagocytosis in BV2 cells[1].
Stictic acid (30 μM; pretreatment for 3 h before Aβ42 stimulation) inhibits Aβ42-induced mRNA expression of IL-6, IL-1β, iNOS, and TNF-α in BV2 cells[1].
Stictic acid (3000 μM) exhibits weak DPPH radical scavenging activity of approximately 10% at 3000 μM[2].
Stictic acid (0.01-100 μM; 48 h) inhibits the growth of HT-29 colon adenocarcinoma cells with an IC50 of 29.29 µg/mL, while showing lower growth inhibition against non-malignant MRC-5 cells[3].
