PD166326
Based on 1 Customer Validation
PD166326 is an orally active tyrosine kinase inhibitor with a IC50 of 8 nM against abl tyrosine kinase and a IC50 of 6 nM against src tyrosine kinase. PD166326 blocks Bcr/Abl kinase activity. PD166326 inhibits Bcr/Abl-dependent proliferation and cell cycle progression. PD166326 reduces peripheral blood granulocytosis, alleviates splenomegaly and prolongs survival in a mouse model of chronic myeloid leukemia. PD166326 can be used in research related to chronic myeloid leukemia.

Animal Model:Balb/c mice[1]
-
Dosage:50 mg/kg
-
Administration:p.o.; twice a day
-
Result:Ensured 100% of treated mice survived 3 to 4 weeks of treatment with no clinical signs of toxicity.
Reduced median spleen weight to 78 mg, over 8-fold less than placebo-treated animals (P < .001); two thirds of treated mice showed complete resolution of splenomegaly (spleen weights in the normal 50-100 mg range).
Lowered median peripheral white blood cell count to 15.0 × 10^9/L, almost 10-fold lower than placebo-treated animals (P < .01); 70% of treated mice achieved a WBC count less than 20.0 × 10^9/L.
Induced a marked reduction in constitutive tyrosine phosphorylation of leukemia-cell proteins, including an average phosphorylated Crk-L (p-Crk-L)/Crk-L ratio of 0.23 and a marked reduction in constitutive Lyn kinase activation, while ERK1/2 activation remained similar to placebo-treated mice.
