Biological Activity of IRAK inhibitor 4

DescriptionIRAK inhibitor 4 is an inhibitor of interleukin- 1 receptor-associated kinase.
TargetsIRAK    

Protocol

Cell Assay [1]
THP-1 cells are grown in RPMI 1640 medium supplemented with 2 mM L-glutamine, 10% heat-inactivated FBS, 100 U/mL penicillin, and 100 μg/mL streptomycin. For monocytic differentiation, cells are seeded in 24-well flat-bottom culture plates at a density of 5×105 cells/well and allowed to adhere and differentiate for 48 h at 37°C in the presence of 100 nM PMA. THP-1 cells are incubated with 0.1 or 1 μM IRAK-4 inhibitor (IRAK inhibitor 1) for 45 min and then stimulated with M. bovis BCG Moreau (MOI 5:1) or E. coli LPS (1 μg/mL). Culture supernatants are collected after 24 h of stimulation and assayed for the concentrations of human TNF-α or IL-12/23p40 by ELISA. For Western blot analysis, cells are incubated with IRAK-4 inhibitor, in the same concentrations described above, for 45 min and then stimulated with M. bovis BCG Moreau (MOI 5:1) or E. coli LPS (1 μg/mL) for 30 min. The cells are then processed for Western blot assay, as described below.

Animal Administration [1]
To evaluate IRAK-4 involvement in mycobacterial infection, IRAK-4+/+ (wild-type), IRAK-4+/- (heterozygous), and IRAK-4-/- (IRAK-4-knockout) mice are used. Eight-week-old mice are infected i.v. with 1×106 CFU of M. bovis strain Moreau. The bacterial loads in the spleens, livers, and lungs are determined at 15, 30, and 60 d postinfection. Briefly, the organs are collected aseptically and homogenized in distilled water that contained 0.05% Tween 80. Serial dilutions of the resulting suspensions are plated on Middlebrook 7H11 agar medium supplemented with 10% oleic acid-albumin-dextrose-catalase, and CFU are counted following a 21-d incubation at 37°C and 5% CO2.

Background on IRAK inhibitor 4

IRAK inhibitor 4 is an inhibitor of interleukin- 1 receptor-associated kinase [1].

IRAK-4 belongs to Interleukin-1 Receptor-Associated Kinase, which are key components in the signal transduction pathways. IRAK-4 is an essential signal transducer downstream of interleukin-1 receptor (IL-1R), interleukin-18 receptor (IL-18R) and Toll-like receptors (TLRs). Inhibition of IRAK-4 can modulate its function, thus toning down inflammatory responses. IRAK inhibitor 4 is an indazole inhibitor. As inhibitors of IRAK-4, imidazo[1,2-b]pyridazines and indazoles are used for treatment of some inflammatory, cell proliferative and immune-related disorders [1].

Quantitative structure-activity relationship (QSAR) study of interleukin-1 receptor associated kinase 4 (IRAK-4) inhibitor activity by the genetic algorithm and multiple linear regression (GA-MLR) method.[Pubmed:20429783]

J Enzyme Inhib Med Chem. 2010 Dec;25(6):844-53.

A linear quantitative structure-activity relationship (QSAR) model is presented for the modelling and prediction for the interleukin-1 receptor associated kinase 4 (IRAK-4) inhibition activity of amides and imidazo[1,2-alpha] pyridines. The model was produced using the multiple linear regression (MLR) technique on a database that consisted of 65 recently discovered amides and imidazo[1,2- alpha] pyridines. Among the different constitutional, topological, geometrical, electrostatic and quantum-chemical descriptors that were considered as inputs to the model, seven variables were selected using the genetic algorithm subset selection method (GA). The accuracy of the proposed MLR model was illustrated using the following evaluation techniques: cross-validation, validation through an external test set, and Y-randomisation. The predictive ability of the model was found to be satisfactory and could be used for designing a similar group of compounds.
