产品详情
Fludarabine triphosphate (F-ara-ATP) trisodium 是 Fludarabine (HY-B0069) 的活性代谢物,是一种有效的、非竞争性的、特异性的DNA引发酶 (DNA primase) 抑制剂,其 IC50 为 2.3 μM,Ki 为 6.1 μM。Fludarabine triphosphate trisodium 通过阻断 DNA 引发酶和引物 RNA 形成抑制 DNA 合成 (DNA synthesis)。Fludarabine triphosphate trisodium 可抑制核糖核苷酸还原酶和DNA聚合酶,最终导致细胞凋亡 (apoptosis)。
生物活性
Fludarabine triphosphate (F-ara-ATP) trisodium, the active metabolite of Fludarabine (HY-B0069), is a potent, noncompetitive and specific inhibitor of DNA primase, with an IC 50 of 2.3 μM and a K i of 6.1 μM. Fludarabine triphosphate trisodium inhibits DNA synthesis by blocking DNA primase and primer RNA formation. Fludarabine triphosphate trisodium inhibits ribonucleotide reductase and DNA polymerase and ultimately leads to cellular apoptosis.
性状
Solid
IC50 & Target[1][2]
IC50: 2.3 ± 0.3 μM (DNA primase); Ki: 6.1 ± 0.3 μM (DNA primase)
体外研究(In Vitro)
Fludarabine triphosphate trisodium is a more potent inhibitor of the polydeoxythymidylate primase activity than of the DNA polymerase α/δ activities present in the supernatants of CCRF-CEM cells.
Fludarabine triphosphate trisodium (10-50 μM) inhibits the incorporation of ATP into primer RNA and dTTP into DNA to a similar extent. has not independently confirmed the accuracy of these methods. They are for reference only.
