生物活性

KRCA-0008 is a selective ALK/Ack1 inhibitor with IC50s of 12 and 4 nM for ALK and Ack1, respectively. KRCA-0008 can be used for the research of cancer.

性状

Solid

IC50 & Target[1][2]

IC50: 12 nM (ALK), 4 nM (Ack1)

体外研究(In Vitro)

KRCA-0008 (0-1000 μM) shows potency to ALK (wt), ALK L1196 M, ALK C1156Y, ALK F1174L, ALK R1275Q and insulin receptor with IC50s of 12, 75, 4, 17, 17 and 210 nM, respectively.
KRCA-0008 (0-1000 nM; 4 h) inhibits ALK-dependent signaling pathways more potently than crizotinib.
KRCA-0008 (0-1000 nM; 72 h) induces cell apoptosis.
KRCA-0008 (0-100 nM; 48 h) affects cell cycle.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line: SU-DHL-1 cell line
Concentration: 0-1 μM
Incubation Time: 72 hours
Result: Dose-dependently increased cspase-3/7 activities and induced cell apoptosis.

Cell Cycle Analysis

Cell Line: Karpas-299 and SU-DHL-1 cell lines
Concentration: 0-100 nM
Incubation Time: 48 hours
Result: Induced G0/G1 cell cycle arrest in ALCL cells expressing NPM-ALK.
体内研究(In Vivo)

KRCA-0008 (25 and 50 mg/kg; p.o. twice a day for two weeks) suppresses tumor growth in an ALK-positive Karpas-299 xenograft model.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: NOD/SCID mice with Karpas-299 xenografts
Dosage: 25 and 50 mg/kg
Administration: Oral gavage; 25 and 50 mg/kg twice a day; for two weeks
Result: Significantly inhibited tumor growth by inhibiting NPM-ALK phosphorylation without showing overt signs of toxicity or significant compound-related body weight loss.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
