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].
