gsk 143

GSK143 is a potent orally active and highly selective inhibitor of spleen tyrosine kinase (SYK) with a pIC 50 of 7.5. Furthermore, GSK143 effectively inhibits phosphorylated Erk (pErk) with a pIC 50 value of 7.1. In addition, GSK143 exhibits promising anti-inflammatory properties by reducing inflammation and impeding the recruitment of immune cells in the intestinal muscularis of mice.

Spleen tyrosine kinase (Syk) inhibitor (pIC50 = 7.5). Also inhibits phosphorylated Erk (pIC50 = 7.1). Decreases cell number and viability in chronic lymphocytic leukemia (CCL) cell lines.

GSK143 dihydrochloride is a highly selective, orally active inhibitor of spleen tyrosine kinase (SYK), exhibiting a pIC 50 value of 7.5. It effectively inhibits phosphorylated Erk (pErk) with a pIC 50 value of 7.1. The compound demonstrates anti-inflammatory properties and hinders the recruitment of immune cells in the intestinal muscularis of mice.
