  • Fraxinellone is isolated from the root bark of the Rutaceae plant, Dictamnus dasycarpus. Fraxinellone is a PD-L1 inhibitor and inhibits HIF-1α protein synthesis without affecting HIF-1α protein degradation. Fraxinellone has the potential to be a valuable candidate for cancer treatment by targeting PD-L1[1].

In Vitro Fraxinellone (0-100 μM；12 hours) decreases the percent of PD-L1 positive cells from 20.4% to 11.4% in A549 cells[1]. Cell Viability Assay[1] Cell Line: A549 cells Concentration: 0 μM, 10 μM, 30 μM, 100 μM Incubation Time: 12 hours Result: Inhibited the percent of PD-L1 positive cells.
In Vivo Fraxinellone (oral gavage; 30 and 100 mg/kg; every three days; 30 days) significantly suppresses tumor growth, reduces HIF-1α, pTyr705 STAT3, PD-L1 and VEGF staining compared with the control group in female athymic BALB/c nude mice[1]. Animal Model: BALB/c nude mice[1] Dosage: 30 and 100 mg/kg Administration: Oral gavage; 30 and 100 mg/kg; every three days; 30 days Result: Significantly suppressed tumor growth.
