生物活性

Obefazimod (ABX464) is a potent anti-HIV agent. Obefazimod inhibits HIV-1 replication in stimulated peripheral blood mononuclear cells (PBMCs) with an IC50 ranging between 0.1 μM and 0.5 μM.

IC50 & Target[1]

HIV-1

0.1-0.5 μM (IC50, in PBMCs)

体外研究
(In Vitro)

Obefazimod inhibits HIV-1 production in PBMC- and macrophages-infected cells. Obefazimod has a strong inhibitory effect for all HIV-1 subtypes tested including subtype B, C and recombinant viruses. Obefazimod also very efficiently inhibits the replication of viral strains harbouring mutations that confer resistance to different therapeutic agents in vitro. While the antiviral drug 3TC is not highly active on K65R and M184V mutant strains, both strains are inhibited by Obefazimod. To generalize the effect of Obefazimod on HIV-1 replication in other primary cells, cells are treated with between 0.01 μM up to 30 μM concentrations of Obefazimod and p24 antigen levels are monitored in culture supernatants over a 12 days period. Obefazimod efficiently blocks virus replication in a dose-dependent manner with an IC50 ranging between 0.1 μM and 1 μM[1].

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

体内研究
(In Vivo)

Humanized mice reconstituted with human lymphoid cells provide rapid, reliable, reproducible experimental systems for testing the efficacy of Obefazimod in vivo. In the initial setting, SCID mice are reconstituted with PBMCs and then infected with the HIV-1 strain JR-CSF. Mice are treated twice a day (b.i.d) for 15 days by oral gavage with 20 mg/kg of Obefazimod. Measures of viral RNA show that the oral treatment with Obefazimod is able to significantly reduce the viral load over a period of 15 days of treatment. FACS analysis of blood samples show that treatment with Obefazimod prevents depletion of CD4+ cells following infection of reconstituted mice and thereby restores the CD8+/CD4+ ratio back to that of non-infected mice[1].

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 3.75 mg/mL (11.07 mM); 澄清溶液

    此方案可获得 ≥ 3.75 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 37.5 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

    生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。
  • 方案 二

    请依序添加每种溶剂: 10% DMSO    90% Corn Oil

    Solubility: ≥ 3.75 mg/mL (11.07 mM); 澄清溶液

    此方案可获得 ≥ 3.75 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。

    1 mL 工作液为例,取 100 μL 37.5 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。

Cell Assay
[1]

The concentration of ABX464 with minimal side effects on cell viability is determined using an MTS test. PBMCs are treated with ABX464 (2, 4, 8, 16, 31, 63, 125, and 250 μM). Cell viability is measured by MTS assay after 6 days of incubation and cytotoxicity is indicated as percentage as compared with untreated cells[1].

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

Animal Administration
[1]

Mice[1]
SCID mice are reconstituted with fresh human PBMCs for two weeks and the reconstitution rates are estimated by human IgG titration. Reconstituted SCID mice are infected with JRCSF HIV-1 strain by intraperitoneal injection. Control group receive labrafil and 5% DMSO by gavage (n=15) and the treated group receive 20 mg/kg b.i.d of ABX464 (n=14) for 15 days[1].

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.
