生物活性

Macitentan (ACT-064992) is an orally active, non-peptide dual ETA and ETB (endothelin receptor) antagonist. Macitentan has the potential for idiopathic pulmonary fibrosis (IPF) and pulmonary arterial hypertension (PAH)[1].

體外研究
(In Vitro)

Tube formation ability is restored when microvascular endothelial cells are preincubated with BOS or macitentan (ACT-064992), also reducing the expression of mesenchymal markers and restoring CD31 expression and the imbalance between VEGF-A and VEGF-A165b[1].
Macitentan inhibits OATP1B1-mediated uptake of atorvastatin and OATP1B3-mediated uptake of estrone-3-sulfate with IC50 ± SE values of 6.3 ± 0.7 and 11.8 ± 5.0?μM, respectively[3].
Treatment with macitentan or with ACT-132577 does not lead to intracellular accumulation of R123 in HeyA8-MDR, showing that these compounds are not P-gp inhibitors[4].

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

體內(nèi)研究
(In Vivo)

Macitentan (ACT-064992; 25 mg/kg/day, p.o.) prevents increased production of vasoactive and fibrogenic factors, NF-κB activation, structural and functional changes, and increases extracellular matrix protein production in type 2 diabetes in type 2 diabetes[2].
Macitentan (10 mg/kg, p.o.) coupled with once-per-week 5 mg/kg taxol, significantly reduces the weight (size) of HeyA8-MDR tumors in mice. Combination therapy with macitentan (10 or 50 mg/kg, but not 5 mg/kg) and taxol or macitentan (10 mg/kg) and cisplatinum significantly reduces the number of proliferating Ki-67-positive cells[4].

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:
——為保證實驗結(jié)果的可靠性,澄清的儲備液可以根據(jù)儲存條件,適當保存;體內(nèi)實驗的工作液,建議您現(xiàn)用現(xiàn)配,當天使用
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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (4.25 mM); 澄清溶液

    此方案可獲得 ≥ 2.5 mg/mL(飽和度未知)的澄清溶液。

    1 mL 工作液為例,取 100 μL 25.0 mg/mL 的澄清 DMSO 儲備液加到 400 μL PEG300 中,混合均勻;再向上述體系中加入 50 μL Tween-80,混合均勻;然后再繼續(xù)加入 450 μL 生理鹽水 定容至 1 mL。

    生理鹽水的配制:將 0.9 g 氯化鈉,溶解于 ddH?O 并定容至 100 mL,可以得到澄清透明的生理鹽水溶液。
  • 方案 二

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

    Solubility: ≥ 2.5 mg/mL (4.25 mM); 澄清溶液

    此方案可獲得 ≥ 2.5 mg/mL(飽和度未知)的澄清溶液,此方案實驗周期在半個月以上的動物實驗酌情使用。

    1 mL 工作液為例,取 100 μL 25.0 mg/mL 的澄清 DMSO 儲備液加到 900 μL玉米油中,混合均勻。

Animal Administration
[2]

Male db/db mice and age and sex-matched controls (27-32?g) are used for the assay. RandomLy selected diabetic animals are monitored for either 2?months or for 4?months after onset of diabetes. Groups (n=7/group) of the diabetic mice are subjected to oral macitentan treatment for the same period (25?mg/kg/day, food admix). The animals are monitored through assessment of body weight and blood glucose.

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.
