| | CIVENTICHEM CV-4057 Usage And Synthesis |
| Description | Laquinimod (248281-84-7) is an immunomodulator1 that inhibits inflammation2 and autoimmunity3,4 via activation of the aryl hydrocarbon receptor (AhR)5. It has been investigated as a treatment for multiple sclerosis6 and has shown efficacy in Huntington’s disease models7,8. | | Uses | 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]. | | Definition | ChEBI: Laquinimod is an aromatic amide. | | Synthesis | b) To a stirred solution of anhydrous tetrahydrofuran (50 mL) of the compound (CAS:1379595-99-9) (10 mmol) was added sodium methanolate (3.6 mmol, 0.5 M, dissolved in methanol) in batches under nitrogen protection. The reaction mixture was heated to reflux for 2 hours. Upon completion of the reaction, the mixture was cooled and the solvent was partially evaporated to give a concentrated solution containing the insoluble salt. The concentrated solution was dissolved in a solvent mixture of methanol (30 mL), 10 M aqueous sodium hydroxide (1.07 mL, 10.7 mmol) and water (15.0 mL). Subsequently, 5 M aqueous hydrochloric acid (2.4 mL, 12.0 mmol) was slowly added to neutralize the reaction mixture. The precipitated crystalline precipitate was collected by filtration, washed with cold methanol and dried to afford the target product 5-chloro-N-ethyl-4-hydroxy-1-methyl-2-oxo-N-phenyl-1,2-dihydroquinoline-3-carboxamide in 87% yield and 98.9% purity. | | in vitro | abr-215062 was shown to completely inhibit the development of murine acute experimental autoimmune encephalomyelitis (eae) [1]. | | in vivo | abr-215062 dose-dependently inhibited disease and showed better disease inhibitory effects as compared to roquinimex (linomide). furthermore, abr-215062 inhibited the inflammation of both cd4+ t cells and macrophages into central nervous tissues [2]. | | IC 50 | NF-κB | | References | [1] STIG JÖNSSON.
