30%propylene glycol 5%Tween80 65%D5W
30.0mg/ml Taking the 1 mL working solution as an example, add 300 μL of 100 mg/ml clarified propylene glycol stock solution to 50 μL of Tween 80, mix evenly to clarify it; then continue to add 650 μL of D5W to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Laquinimod (ABR-215062, LAQ) is a potent immunomodulator. Phase 3.
in vitro Laquinimod treatment at 0.1-1 μM does not affect the viability of peripheral blood mononuclear cells (PBMC). By performing the large-scale gene expression microarray analysis in PBMC from healthy subjects or relapsing-remitting multiple sclerosis (RRMS) patients, Laquinimod is shown to induce suppression of genes related to antigen presentation and corresponding inflammatory pathways. Laquinimod induces activation of Th2 response in CD14+ and CD4+ cells and suppression of proliferation in CD8+ cells. Laquinimod displays significant effects on immune modulation related to the suppression of antigen presenting mechanism followed by a decrease of chemotaxis and adhesion, and exhibits potent anti-inflammatory potency through the suppression of the NF-κB pathway that concordantly leads to the activation of apoptosis of immuno-competent cells. [5]
in vivo Administration of Laquinimod (0.16-16 mg/kg/day) dose-dependently inhibits the incidence of experimental autoimmune neuritis (EAN) in Lewis rats, ameliorates clinical signs and inhibits P0 peptide 180-199-specific T cell responses as well as the inflammation and demyelination in the peripheral nerves, suggesting that Laquinimod may mediate its effects by regulation of Th1/Th2 cytokine balance. [1] Laquinimod significantly inhibits the development of murine acute experimental autoimmune encephalomyelitis (EAE), being approximately 20 times more potent than the immunomodulator roquinimex. [2] Laquinimod treatment inhibits the development of experimental autoimmune encephalomyelitis (EAE) in the Lewis rat in a dose-dependent manner, and shows better disease inhibitory effects as compared to roquinimex (Linomide). [3] Laquinimod potently inhibits the development of chronic experimental autoimmune encephalomyelitis (chEAE) in IFN-beta k.o. mice and wild type mice. [4] Laquinimod reduces clinical signs, inflammation, and demyelination in C57BL/6 mice with active EAE induced with MOG(35-55) peptide, and down-regulates VLA-4-mediated adhesiveness and pro-inflammatory cytokines such as IL-17. [6] The study of Laquinimod in the mice model of EAE using a conditional BDNF knockout strain lacking BDNF expression in myeloid cells and T cells (LLF mice) indicates Laquinimod also modulates autoimmune demyelination via induction of brain-derived neurotrophic factor (BDNF).

細胞アッセイ 細胞株 PBMC
濃度 Dissolved in PBS, final concentrations ~1 μM
反応時間 24 hours
実験の流れ The peripheral blood mononuclear cells (PBMC) are incubated with Laquinimod for 24 hours. Cell viability is measured on total PBMC by propidium iodide (PI) staining using an automated cell counter. Protein expression level is assessed in PBMC samples by Western blot using anti-HLA-DQA/DQB monoclonal antibodies.
