生物活性

LQZ-7I is a survivin-targeting inhibitor. LQZ-7I inhibits survivin dimerization. LQZ-7I orally effectively inhibits xenograft tumor growth and induces survivin loss in tumors[1].

體外研究
(In Vitro)

與母體化合物 LQZ-7 相比,LQZ-7I 提高了細(xì)胞毒性,對 C4-2 細(xì)胞的 IC50 為 3.1 μM,對 PC-3 細(xì)胞的 IC50 為 4.8 μM[1]
LQZ-7I (10 μM;0-6 小時(shí)) 處理可降低生存素的表達(dá)。然而,LQZ-7I 不會降低 XIAP、CIAP1 和 CIAP2 的表達(dá)。LQZ-7I 可能對其預(yù)期目標(biāo) survivin 具有選擇性[1]

Western Blot Analysis[1]

Cell Line: PC-3 or C4-2 cells
Concentration: 10 μM
Incubation Time: 0-6 hours
Result: Reduced the expression of survivin.
體內(nèi)研究
(In Vivo)

LQZ-7I (100 mg/kg;隔日灌胃,共 10 次處理) 顯著抑制腫瘤生長,對小鼠沒有任何明顯的不良影響[1]。

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

Animal Model: 6-week old male NSG mice[1]
Dosage: 100 mg/kg; 200 μL vehicle (90% corn oil/10% DMSO)
Administration: Oral gavage every other day for a total of ten treatments
Result: Significantly suppressed tumor growth without any notable adverse effect on the mice as indicated by lacking changes in body weight and in wet weight of major organs at the end of the study.

以下溶解方案都請先按照 In Vitro 方式配制澄清的儲備液,再依次添加助溶劑:
——為保證實(shí)驗(yàn)結(jié)果的可靠性,澄清的儲備液可以根據(jù)儲存條件,適當(dāng)保存;體內(nèi)實(shí)驗(yàn)的工作液,建議您現(xiàn)用現(xiàn)配,當(dāng)天使用
以下溶劑前顯示的百分比是指該溶劑在您配制終溶液中的體積占比;如在配制過程中出現(xiàn)沉淀、析出現(xiàn)象,可以通過加熱和/或超聲的方式助溶

  • 方案 一

    請依序添加每種溶劑: 10% DMSO    90% Corn Oil

    Solubility: ≥ 2.08 mg/mL (5.97 mM); 澄清溶液

    此方案可獲得 ≥ 2.08 mg/mL(飽和度未知)的澄清溶液,此方案實(shí)驗(yàn)周期在半個月以上的動物實(shí)驗(yàn)酌情使用。

    1 mL 工作液為例,取 100 μL 20.8 mg/mL 的澄清 DMSO 儲備液加到 900 μL玉米油中,混合均勻。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
