Strictinin
Based on 1 Customer Validation
Strictinin is an orally active phenolic compound. Strictinin reduces xanthine oxidase activity, uric acid production, and the activation of ERK1/2, JNK, NF-κB, and NLRP3 inflammasome components in hepatocytes treated with Xanthine (HY-W017389). Strictinin decreases elevated serum uric acid levels and enhanced xanthine oxidase activity in mice treated with potassium oxonate. Strictinin acts as a ROR1 inhibitor and exhibits anticancer activity against highly aggressive non-androgen-dependent prostate cancer. Strictinin induces cancer cell apoptosis (apoptosis), arrests cell cycle, and inhibits cancer cell migration, invasion, and epithelial-mesenchymal transition. Strictinin modulates gut microbiota, inhibits bacterial growth and biofilm formation, accelerates small intestinal transit, and blocks viral entry and replication. Strictinin can be used in research related to hyperuricemia, androgen receptor-negative non-androgen-dependent prostate cancer, triple-negative breast cancer, bacterial infections, constipation, coronavirus infections, dental caries, and infections caused by influenza A, influenza B, and human parainfluenza virus type 1.

Strictinin (50-500 μM; 24 h) exhibits cytotoxicity against AML12 mouse hepatocytes only at the concentration of 500 μM[1].
Strictinin (100-250 μM; 4-24 h) inhibits XOD activity and uric acid (UA) production in Xanthine (HY-W017389)-treated AML12 mouse hepatocytes, and suppresses IL-1β expression in these cells[1].

Strictinin (31.25-1000 μM; 72 h) potently inhibits the viability of PC3 cells with an IC50 of 277.2 μmol/L, whereas its toxicity toward normal RWPE-1 cells is much lower (IC50 = 658.5 μmol/L)[2].
Strictinin (250 μM; 24-72 h) induces significant apoptosis in PC3 cells, reduces the number of viable cells, increases the populations of total apoptotic and dead cells, and triggers caspase 3/7-mediated apoptosis[2].
Strictinin (250 μM; 24-48 h) inhibits the expression of ROR1 in PC3 and DU145 cells, blocks the downstream PI3K-AKT-GSK3β pro-survival signaling pathway, and suppresses the expression of EMT markers Twist1, Snail and MMP9 in the cells[2].

Strictinin (4-100 µM) inhibits MHV plaque formation in mouse L cells in a concentration-dependent manner. Under the condition of full co-treatment, 100 µM Strictinin completely blocks plaque formation, while 20 µM reduces the plaque formation rate to <25% of that in the control group[5].
Strictinin (100 µM; administered during infection, harvested at 12 and 24 hpi) completely abrogates the expression of viral nucleocapsid protein in MHV-infected mouse L cells[5].
