生物活性 | GSK143 dihydrochloride is an orally active and highly selectivespleen tyrosine kinase (SYK)inhibitor with apIC50of 7.5. GSK143 dihydrochloride inhibits phosphorylatedErk(pErk:pIC50=7.1)[1]. GSK143 dihydrochloride reduces inflammation and prevents recruitment of immune cells in the intestinal muscularis in mice[2][3]. |
IC50& Target | pIC50: 7.5 (SYK) and 7.1 (pErk)[1] |
体外研究 (In Vitro) | GSK143 dihydrochloride (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 dihydrochloride (10-10000 nM; every 24 hours for 3 days) has an IC50of 323 nM in CLL cells. GSK 143 dihydrochloride (1 μM; 30 mins) abrogates early signalling events including SYK phosphorylation and calcium flux[2]. GSK143 dihydrochloride (0.1-10 μM; for 30 min) reduces cytokine expression in bone marrow derived macrophages in a concentration-dependent manner[3].
Cell Viability Assay[2] Cell Line: | Chronic lymphocytic leukaemia (CLL) cells | Concentration: | 10, 100, 1000, 10000 nM | Incubation Time: | Every 24 hours for 3 days | Result: | Had an IC50of 323 nM. |

体内研究 (In Vivo) | GSK143 (0.1-10 mg/kg; orally; 1.5 hours) reduces inflammation and prevents recruitment of immune cells in the intestinal muscularis of 1 mg/kg[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 T1/2of 4.2 hours, low clearance (16 mL/min/kg), moderate bioavailability of 30% and a Vssof 4.1 L/kg in rats[1].
Animal Model: | Wild type C57NL/BL6 mice, 10-12 weeks old[3] | Dosage: | 0.1, 1, 3, 10 mg/kg | Administration: | Orally; 1.5 hours before intestinal manipulation (IM) | Result: | Reduced inflammation and prevented recruitment of immune cells in the intestinal muscularis. |
Animal Model: | Male CD rats (175-200 g)[1] | Dosage: | 1 mg/kg of iv; 3 mg/kg of po (Pharmacokinetic Analysis) | Administration: | IV or PO | Result: | Had a T1/2of 4.2 hours, low clearance (16 mL/min/kg), moderate bioavailability of 30% and a Vssof 4.1 L/kg. |
