产品描述:
Lymphocyte-specific protein tyrosine kinase (LCK) is a member of the Src-family of non-receptor protein tyrosine kinases and plays a critical role in the initial steps of T cell receptor signaling that trigger the production of cytokines.{24187} LCK inhibitor is a pyrrolopyrimidine that blocks the activity of two forms of LCK kinase, LCK (64-509) and LCKCD, with IC50 values of 50s = 70 nM, 1.57, and 1.98 µM, respectively) and only minimally inhibits the activities of EGFR, PKC, CDC2/B and ZAP-70 (IC50s = 3.2, >33, >50, and >50 µM, respectively).{24189,24188} This compound has been shown to inhibit T cell receptor-stimulated IL-2 production in mice (ED50s = 4 and 25 mg/kg when administered either i.p. or orally).{24189,24190}
