产品说明

DescriptionJANEX-1 is a small molecule inhibitor of JAK3 that selectively inhibits JAK3 at an IC50 of 78 µM without altering the activity of JAK1 or JAK2, or any other protein tyrosine kinases (IC50 ≥ 350 µM).In vitroJANEX-1 inhibits JAK3 but not JAK1 or JAK2. The ZAP/SYK family tyrosine kinase SYK, TEC family tyrosine kinase Bruton’s tyrosine kinase (BTK), SRC family tyrosine kinase LYN, and receptor family tyrosine kinase insulin receptor kinase (IRK) are not inhibited by JANEX-1[1]. JANEX-1 suppresses IL-1β and IFN-γ-induced phosphorylation of STAT-1, STAT-3, and STAT-5 proteins. JANEX-1 has a potent inhibitory effect on cytokine-induced β-cell damage[2]. In vivoJANEX-1 is very well tolerated by mice and monkeys and effective plasma concentrations of JANEX-1 could be achieved at nontoxic dose levels. JANEX-1 suppresses the mitogen and antigen responses of T-cells and attenuates the severity of T-cell-dependent graft-versus-host disease in a bone marrow transplantation model[1].
