    Triptolide purchased from MCE. Usage Cited in: Int J Mol Sci. 2016 Dec 19;17(12). pii: E2139.  [Abstract]

    To explore the cellular mechanisms for the suppression of CNE cells by TPL and IR, the expression of p65, phosph-p65, Bcl-2, and Bax in CNE cells are examined by Western blot, with β-actin as protein loading control. Western blot assay for Bax, Bcl-2, phosph-p65, and p65 expression in vitro with combined treatment with TPL and IR.

    Triptolide 在培養(yǎng)的和原發(fā)性慢性淋巴細(xì)胞白血病 (CLL) B 細(xì)胞中誘導(dǎo)細(xì)胞凋亡。用 Triptolide 處理 CD19+ B 細(xì)胞,誘導(dǎo)培養(yǎng)的和原代 CLL 細(xì)胞凋亡的劑量依賴性增加。Triptolide 對高風(fēng)險(xiǎn) (n=5) 和低風(fēng)險(xiǎn) CLL (n=12) B 細(xì)胞 (10-50 nM 范圍) 具有選擇性毒性,同時(shí)在很大程度上保留正常 B 細(xì)胞 (n=5)。與抑制熱休克誘導(dǎo)的 HSP 轉(zhuǎn)錄一致,Triptolide 處理可減弱熱休克誘導(dǎo)的 HSP 表達(dá)[1]。
    Triptolide 是一種源自中國植物雷公藤的天然產(chǎn)物,據(jù)報(bào)道在多種癌癥中表現(xiàn)出抗腫瘤作用。Triptolide 以劑量依賴性方式抑制 MDM2 表達(dá),即使在 20-100 nM 的低濃度下,在急性淋巴細(xì)胞白血病 (ALL) 細(xì)胞中也是如此。Triptolide 在所有 8 種具有天然 MDM2 過表達(dá)的細(xì)胞系中表現(xiàn)出強(qiáng)烈的細(xì)胞毒活性,IC50 值范圍為 47 到 73 nM。雷公藤甲素對表達(dá)極低水平 MDM2 的 EU-4 細(xì)胞的細(xì)胞毒性作用要小得多,而當(dāng) MDM2 穩(wěn)定轉(zhuǎn)染時(shí),雷公藤甲素能有效殺死這些細(xì)胞 (IC50 值:725 nM 對 88 nM)[2]。
    分化的 PC12 細(xì)胞與不同濃度的 Triptolide (0.01、0.1 和1 nM) 在10 μM Aβ25-35 存在下孵育 24 小時(shí),MTT 法檢測雷公藤甲素的作用.結(jié)果表明,Aβ25-35可降低細(xì)胞活力,Triptolide 處理后分化的PC12細(xì)胞活力顯著增加。結(jié)果表明雷公藤甲素可以減輕 Aβ25-35引起的細(xì)胞損傷,說明雷公藤甲素具有神經(jīng)保護(hù)作用[3]。

    體內(nèi)研究
    (In Vivo)

    小鼠接受靜脈注射后 Triptolide (TP) 血漿濃度迅速下降。注射 2 小時(shí)后,所有三組的 Triptolide 濃度均降至低于定量下限。在對照組和處理組之間進(jìn)行參數(shù)比較,以評估 P-gp 抑制對 Triptolide 暴露和消除的影響。mdr1a-siRNA處理可顯著增加雷公藤甲素血漿暴露,Cmax從 413±74 增加到510±94 ng/mL (P<0.05),AUC 從 103.5±9.6 增加到 154.3±30.2 ng h/mL (P<0.05)。在 Tariquidar 的伴隨組中,還注意到顯著增加的 AUC,從對照的 103.5±9.6 到 Triptolide + Tariquidar 組的 145.9±24.6 ng h/mL。因此,雷公藤甲素在小鼠體內(nèi)的總體清除率顯著降低,從對照組的 9564±1024.2 mL/min/kg 降至對照組的 6576.4±1438.5 (P<0.05) 和對照組的 5755.4±1200.1 mL/min/kg (P<0.05) 分別為雷公藤甲素+Tariquidar和雷公藤甲素+mdr1a-siRNA組[4]。

    Cell Assay
    [3]

    The viability of differentiated PC12 cells treated with different concentrations of Triptolide. After differentiated PC12 cells are cultured on 96-well plates with RPMI 1640 medium for stabilization, differentiated PC12 cells are incubated with different concentrations of Triptolide (0.01, 0.1, and 1 nM) for 24 hours. The concentrations in this study are chosen. Then cell viability is determined by the MTT assay. Each condition and experiment is repeated three times[3].

    Animal Administration
    [4]

    Mice[4]
    Male BALB/C mice (weight, 18-22 g) are used. For Triptolide (TP) plasma kinetic study and toxicological evaluation, mice are divided into four groups (n=5 each) to collect blood and tissue samples: (1) normal+saline group; (2) 1.0 mg/kg Triptolide+15 nmol negative control (NC) siRNA-siRNA group; (3) 1.0 mg/kg Triptolide+15 nmol mdr1a-siRNA group; (4) 1.0 mg/kg Triptolide+10 mg/kg Tariquidar group. In order to avoid the complication caused by drug absorption or possible intestinal first-pass effect, Triptolide and the inhibitor are intravenously administrated to mice. The siRNA group is intravenously injected with NC-siRNA or mdr1a-siRNA 2 days before Triptolide dose. For Triptolide+Tariquidar group, the mice are received an intravenous Tariquidar dose 20 min prior to the Triptolide injection. Blood samples are collected at 2, 5, 10, 15, 30, 60 and 120 min after Triptolide dosing. To assess the liver exposure of Triptolide, liver tissue samples are collected from another set of mice at 5, 30, 60 and 120 min after dosing. Three Triptolide groups are design for this experiment, including Triptolide+NC-siRNA group, Triptolide+mdr1a-siRNA group and Triptolide+Tariquidar group. The liver tissue samples are weighed and then homogenized in 10 volume (w:v) of ice-cold saline. The concentrations of Triptolide in plasma and liver tissue are measured by a validated LC-MS/MS method.

    • 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.
