Clifutinib

Customer Review

Based on 1 Customer Validation

Clifutinib is an orally active and selective internal tandem duplication mutation of FMS-like tyrosine kinase 3 (FLT3-ITD) inhibitor with an IC₅₀ value of 15.1 nM. Clifutinib exerts strong antiproliferative effects on FLT3-ITD acute myeloid leukemia (AML) cell lines (MV-4-11: IC₅₀ = 1.5 nM; MOLM-13: IC₅₀ = 1.4 nM). Clifutinib inhibits the activity of FLT3-ITD kinase and blocks the downstream RAS/MAPK, PI3K/AKT, and JAK/STAT5 signaling pathways of FLT3. Clifutinib induces apoptosis of acute myeloid leukemia (AML) cells with FLT3-ITD mutations. Clifutinib demonstrates significant antitumor efficacy in mice bearing MV-4-11 or MOLM-13 xenografts. Clifutinib is promising for research of relapsed/refractory FLT3-ITD-positive acute myeloid leukemia.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
