SU11657

(Synonyms: N,N-Dimethyl sunitinib)

SU11657 (N,N-Dimethyl sunitinib) is an orally active multi-targeted tyrosine kinase inhibitor with IC₅₀ values of 0.04 μM (c-Kit), 0.005 μM (PDGFR), 0.013 μM (VEGFR1), 0.017 μM (VEGFR2) and 50 nM (FLT3), respectively. SU11657 exhibits anti-angiogenic activity. SU11657 delays leukemia progression, synergizes with ATRA (HY-14649) to reduce leukemia burden, and inhibits symptoms and tissue damage associated with rheumatoid arthritis. SU11657 can be used in research related to FLT3-mutated acute promyelocytic leukemia, rheumatoid arthritis, neuroblastoma, and benign/atypical meningioma.

In Vitro

SU11657 (5-500 nM; 2 h) potently inhibits the autophosphorylation of FLT3-ITD in MV 4;11 leukemia cells, with an IC₅₀ of approximately 50 nM^[1].
SU11657 potently inhibits the kinase activities of purified VEGF-RI, VEGF-RII, PDGF-R and c-Kit proteins in vitro, with the strongest inhibitory activity against PDGF-R (IC₅₀ = 0.005 μM) and the weakest inhibitory activity against c-Kit (IC₅₀ = 0.04 μM)^[2].
SU11657 (0-5.0 μM; 72 h) potently inhibits the proliferation of primary HUVECs, primary atypical meningioma cells and primary benign meningioma cells in a 72-hour experiment, with the strongest inhibitory activity against HUVECs (IC₅₀ = 0.2 μM), followed by that against atypical meningioma cells (IC₅₀ = 0.5 μM), and the weakest activity against benign meningioma cells (IC₅₀ = 1.6-1.75 μM)^[4].
SU11657 (0-5.0 μM; 14-21 days) reduces the clonogenic survival rate of primary benign meningioma cells and primary atypical meningioma cells in a dose-dependent manner, with a significantly stronger effect on atypical meningioma cells^[4].
SU11657 (100 nM-1 μM) significantly enhances the inhibitory effect of radiation on the clonogenic survival of primary benign meningioma cells and primary atypical meningioma cells, with a more prominent synergistic effect observed in atypical meningioma cells^[4].
SU11657 reduces HUVEC invasion induced by primary benign meningioma cells and primary atypical meningioma cells, and also attenuates the radiation-induced enhancement of this proangiogenic paracrine effect^[4].

In Vivo

SU11657 (20 mg/kg; p.o.; daily; 4 days) modestly impairs leukemia progression as a single agent, and synergizes with ATRA (HY-14649) to rapidly reduce leukemic cell mass and restore normal hematopoiesis in a murine model of acute promyelocytic leukemia with activated FLT3^[1].

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.
