KAPPA-CARRAGEENAN SULFATED PLANT POLYSACCHARIDE

General description

A cell-permeable, ATP competitive, and reversible indoloazepine compound that displays anti-proliferative and anti-inflammatory properties. Acts as a potent inhibitor of Chk2 (IC₅₀ = 8 nM) that targets the ATP binding pocket. Exhibits selectivity for Chk2 over MEK1, Chk1, CK1δ, PKCα, PKCβII and CK2 (IC₅₀ = 89 nM, 237 nM, 1.352 µM, 2.539 µM, 3.381 µM, and >10.0 µM, respectively). Blocks the production of IL-2 and TNF-α by preventing the transcriptional activation of NF-κB (IC₅₀ = 3.55 µM for IL-2 production in PMA-stimulated Jurkat T cells; 8.16 µM for TNF-α production in LPS-stimulated THP-1 cells). Also reported to suppress the growth of leukemic T cells (GI₅₀ = 1.73 µM).
