产品名称
VX-944
产品介绍
AVN-944 (VX-944) 是一种口服有效、选择性、非竞争性和特异性的IMPDH(肌苷一磷酸脱氢酶)抑制剂。AVN-944 是从头合成鸟嘌呤核苷酸的必要限速酶。AVN-944 也是一种沙粒病毒 RNA 合成 (arenavirus RNA synthesis) 抑制剂，可阻断沙粒病毒感染。AVN-944 具有广泛的抗癌活性，可用于多发性骨髓瘤 (MM) 和急性髓系白血病 (AML) 的研究。
生物活性

AVN-944 (VX-944) is an orally active, potent, selective, noncompetitive and specific inhibitor ofIMPDH(inosine monophosphate dehydrogenase). AVN-944 is an essential rate-limiting enzyme in de novo guanine nucleotide synthesis. AVN-944 is also an inhibitor ofarenavirusRNA synthesis, and blocksarenavirusinfection. AVN-944 has broad anti-cancer activities, and can be used for multiple myeloma (MM) and acute myeloid leukemia (AML) research[1][2][3].

体外研究
(In Vitro)

AVN-944 (0-1 μM, 48 h) inhibits growth of human multiple myeloma (MM) cell lines in a dose-dependent manner[1].
AVN-944 (800 nM, 0-72 h) inducesapoptosisin MM cell lines via a caspase-independent, Bax/AIF/Endo G pathway[1].
AVN-944 (0-200 nM) enhances the cytotoxicity ofDoxorubicin(HY-15142A) andMelphalan(HY-17575)[1].
AVN-944 inhibits the proliferation of the human MV-4-11 and murine Ba/F3-Flt3-ITD-dependent cell lines with IC50values of 26 and 30 nM, respectively[2].
AVN-944 (0-32 μM, 48 h) shows good activity against arenavirus infection at low doses (7.5 μM) with less cytotoxicity[3].
AVN-944 (0-6.4 μM, 48 h) does not reduce the viability of peripheral blood mononuclear cells (PBMNCs)[1].

Cell Proliferation Assay[1]

Cell Line:RPMI8226, MM.1S, and U266 cells
Concentration:0, 100, 200, 300, 400, 600, 1000 nM
Incubation Time:48 h
Result:Significantly inhibited the growth of RPMI8226, MM.1S, and U266 cells in a dose-dependent fashion, with 50% inhibition (IC50) values at 48 h of 450, 450, and 600 nM, respectively. Inhibited growth of drug-resistant cell lines, including Doxorubicin (Dox)-resistant RPMI8226-Dox40, Melphalan (Mel) resistant RPMI8226-LR5, and Dex (Dexamethasone) resistant MM.1R cells, with IC50values similar to the parental drug-sensitive cell lines.

Apoptosis Analysis[1]

Cell Line:MM.1S and RPMI8226 cells
Concentration:800 nM
Incubation Time:48 and 72 h
Result:Induced apoptosis in MM cell lines.

Western Blot Analysis[1]

Cell Line:MM.1S and RPMI8226 cells
Concentration:800 nM
Incubation Time:12, 24, 48 h
Result:Induced modest cleavage of caspase 3, 8 and 9 in MM.1S cells and RPMI8226 cells. Markedly upregulated Bax and Bak, without significant changes in Bcl-2, Mcl-1, XIAP, and Bad. Observed translocation of mitochondrial proapoptotic proteins, apoptosis-inducing factor (AIF) and endonuclease G (Endo G) to cytosolic fractions.

Cell Cytotoxicity Assay[1]

Cell Line:MM.1S cells, MM.1S cells cultured with BMSCs
Concentration:0, 50, 200 nM
Incubation Time:24 h
Result:Enhanced the cytotoxicity of of Doxorubicin and Melphalan in MM.1S cells. Additive effects were also observed in MM.1S cells cultured with BMSCs derived from MM patient.
体内研究
(In Vivo)

AVN-944 (0-150 mg/kg, Orally, twice daily) significantly increases the median survival time of leukemia model mice[2].

Animal Model:Balb/c mice (leukemia model, using Ba/F3 cells transduced with an activating human Flt-3 mutation injected into mice)[2]
Dosage:75 or 150 mg/kg
Administration:Orally, twice daily
Result:Provided a significant increase in median survival time. Three of the 12 mice treated with 150 mg/kg AVN-944 were still alive on Day 35 when the study was terminated.
