Fraxinellone  纯度: 99.99%

Fraxinellone 是从芸苔科植物 Dictamnus dasycarpus 的根皮中分离出来的。 Fraxinellone 是 PD-L1 抑制剂，可抑制 HIF-1α 蛋白质合成，而不会影响 HIF-1α 蛋白质降解。 Fraxinellone 通过靶向 PD-L1，有用于癌症免疫的潜能。

生物活性

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].

体外研究
(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.

体内研究
(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].
