生物活性

Laquinimod (ABR-215062), an orally available carboxamide derivative, is a potent immunomodulator which prevents neurodegeneration and inflammation in the central nervous system. Laquinimod reduces astrocytic NF-κB activation to protect from Cuprizone-induced demyelination. Laquinimod has?the?potential?for relapsing remitting (RR) and chronic progressive (CP) forms of multiple sclerosis (MS; RRMS or CPMS) as well as neurodegenerative diseases?research[1][2][3][4].

IC50 & Target[3]

NF-κB

 

體外研究
(In Vitro)

Laquinimod reverses EAE and inhibits pathogenic T cell immune responses. Laquinimod reverses RR-EAE and inhibits inflammatory T cell responses via a direct effect on myeloid APC. Laquinimod alters myeloid APC subsets and inhibits Th1 and Th17 polarization of myelin-specific T cells. Laquinimod-induced type II (M2) monocytes reverse established EAE[1]. Laquinimod modulates the phenotype of B cells of healthy donors. Laquinimod modulates expression of markers related to regulatory capacity in B cells of RRMS patients. Laquinimod reduces IFNγ cytokine expression in CD4+ T cells[2].

體內(nèi)研究
(In Vivo)

Laquinimod treatment inhibits donor myelin-specific T cells from transferring EAE to naive recipient mice. In vivo laquinimod treatment alters subpopulations of myeloid antigen presenting cells (APC) that include a decrease in CD11c+CD11b+CD4+?dendritic cells (DC) and an elevation of CD11bhiGr1hi monocytes[1].

  • 方案 一

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

    Solubility: ≥ 2.5 mg/mL (7.01 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(shí)驗(yàn)周期在半個月以上的動物實(shí)驗(yàn)酌情使用。

    以 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。

Cell Assay
[1]

Purified CD11b+?cells from laquinimod- or vehicle-treated mice are cultured with naive CD4+ cells isolated from laquinimod- or vehicle-treated 2D2 mice and antigen (MOG p35-55, 20 μg/mL). Cells are cultured in 96-well microtitre plates at a concentration of 0.25×106?cells/mL. Culture medium consisted of RPMI 1640 supplemented with L-glutamine (2 mM), sodium pyruvate (1 mM), penicillin (100 U/mL), streptomycin (0.1 mg/mL), 2-mercaptoethanol (5×10-5 M) and 10% (v/v) fetal bovine serum. Cells are incubated for 48 h and pulsed for 18 h with 1 μCi per well of [3H]-thymidine before harvesting.

Animal Administration
[1]

Seven to 10-week-old female C57BL/6, DBA/1 or SJL/J mice are injected subcutaneously with 50 μg MOG p35-55, 50 μg rMOG or 100 μg PLP p139-151, respectively, in complete Freund's adjuvant. After immunization and 2 days later, mice receive 200 ng (C57BL/6) or 100 ng (SJL/J) pertussis toxin intraperitoneally (i.p.). For adoptive transfer, donor SJL/J mice are immunized as described above and treated daily with laquinimod or vehicle. 10 days later, cells from draining lymph nodes and spleen are isolated, re-stimulated for 48 h (20 μg/mL PLP p139-151), and injected i.p. into naive SJL/J recipients (107?cells per mouse). Animals are observed daily and clinical scores are assessed as follows: 0, no signs; 1, decreased tail tone; 2, mild monoparesis or paraparesis; 3, severe paraparesis; 4, paraplegia and/or quadraparesis; and 5, moribund or death.

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.
