1254053-43-4 Usage
in vivo
In vivo, gilteritinib is distributed at high levels in xenografted tumors after oral administration. The decreased FLT3 activity and high intratumor distribution of gilteritinib translates to tumor regression and improved survival in xenograft and intra-bone marrow transplantation models of FLT3-driven AML. This antitumor activity is associated with a durable inhibition of phospho-FLT3 and phospho-STAT5. Furthermore, treatment with gilteritinib decreases the leukemic burden and prolongs survival in a mouse IBMT model. No overt toxicity is seen in mouse models treated with gilteritinib
Description
Gilteritinib is an inhibitor of FMS-related tyrosine kinase 3 (FLT3; IC50 = 5 nM for the wild-type enzyme). It inhibits mutant forms of FLT3, including FLT3 with the internal tandem duplication mutation (FLT3-ITD), FLT3-ITD expressing the F691L mutation, and FLT3 with various tyrosine kinase domain mutations (FLT3-TKD; IC50s =1.4-1.8, 12.2, and 0.7-2 nM, respectively). Gilteritinib also inhibits Axl and c-Kit with IC50 values of 41 and 102 nM, respectively. It decreases the viability of blast cells isolated from patients with relapsed acute myeloid leukemia (AML) in a concentration-dependent manner. Formulations containing gilteritinib have been used in the treatment of AML.
Uses
Gilteritinib is an AXL inhibitor in cancer.

Check Digit Verification of cas no
The CAS Registry Mumber 1254053-43-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,0,5 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1254053-43:
(9*1)+(8*2)+(7*5)+(6*4)+(5*0)+(4*5)+(3*3)+(2*4)+(1*3)=124
124 % 10 = 4
So 1254053-43-4 is a valid CAS Registry Number.
