GSK143
Based on 1 publication(s) in Google Scholar
GSK143 is an orally active and highly selective spleen tyrosine kinase (SYK) inhibitor with a pIC50 of 7.5. GSK143 inhibits phosphorylated Erk (pErk: pIC50=7.1). GSK143 reduces inflammation and prevents recruitment of immune cells in the intestinal muscularis in mice.

Biological Activity
pIC50: 7.5 (SYK) and 7.1 (pErk)[1]
GSK143 (compound 20) inhibits ZAP-70 (pIC50=4.7), LCK (pIC50=5.3), LYN (pIC50=5.4), JAK1/2/3 (pIC50=5.8/5.8/5.7), Aurora B (pIC50=4.8), hWB (pIC50=6.6), hERG (pIC50=4.7)[1].
GSK143 (10-10000 nM; every 24 h for 3 days) has an IC50 of 323 nM in CLL cells. GSK 143 (1 μM; 30 mins) abrogates early signalling events including SYK phosphorylation and calcium flux[2].
GSK143 (0.1-10 μM; for 30 min) reduces cytokine expression in bone marrow derived macrophages in a concentration-dependent manner[3].

GSK143 (3, 10, 30, 100 mg/kg; oral; 1 hour before ovalbumin challenge) reduces the cutaneous reverse passive Arthus reaction in a dose dependent manner by approximately 50% and 70% at 10 mg/kg and 30 mg/kg, respectively[2].
GSK143 (iv of 1 mg/kg; po of 3 mg/kg) has a T1/2 of 4.2 hours, low clearance (16 mL/min/kg), moderate bioavailability of 30% and a Vss of 4.1 L/kg in rats[1].
