MAX-40279 hydrochloride is a dual and orally active inhibitor of FLT3 kinase and FGFR kinase. MAX-40279 hydrochloride is also effective against the FLT3 mutants such as FLT3D835Y, suggesting that it can overcome resistance to Quizartinib (HY-13001) and Sorafenib (HY-10201). MAX-40279 hydrochloride inhibits NDRG1 phosphorylation at Ser330 and suppresses endothelial-to-mesenchymal transition (EndMT). MAX-40279 hydrochloride can be used for the research of acute myelogenous leukemia (AML).

Description

MAX-40279 hydrochloride is a dual and orally active inhibitor of FLT3 kinase and FGFR kinase. MAX-40279 hydrochloride is also effective against the FLT3 mutants such as FLT3D835Y, suggesting that it can overcome resistance to Quizartinib (HY-13001) and Sorafenib (HY-10201). MAX-40279 hydrochloride inhibits NDRG1 phosphorylation at Ser330 and suppresses endothelial-to-mesenchymal transition (EndMT). MAX-40279 hydrochloride can be used for the research of acute myelogenous leukemia (AML)[1][2][3].

IC50 & Target

FLT3 and FGFR[1]

In Vitro

MAX-40279 (0.5-1 μM, 48 h) hydrochloride impedes EndMT by inhibiting NDRG1 phosphorylation at Ser-330 in HUVECs, MAECs, and MPLECs[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Migration Assay [3]

Cell Line: HUVECs
Concentration: 0.5 and 1 μM
Incubation Time: 48 h
Result: Attenuated migration of HUVEC induced by H2O2 and TGF-β.

Western Blot Analysis[3]

Cell Line: HUVECs, MAECs, and MPLECs
Concentration: 0.5 and 1 μM
Incubation Time: 48 h
Result: Significantly inhibited the phosphorylation of NDRG1 at Ser-330.
Reduced the total protein level of NDRG1.
Inhibited the expression of mesenchymal markers such as ZEB1, α-SMA, Slug, Snail, and TAGLN.
In Vivo

MAX-40279 (12 mg/kg, p,o., once daily for 7 days) hydrochloride is effective in 43% of patient tumor samples in mouse Mini-PDX assay[1].
MAX-40279 (12 mg/kg, p,o., twice daily for 21-28 days) hydrochloride significantly inhibited tumor growth in MV4-11 and KG-1 cells induced mice xenograft models[1].
MAX-40279 (7-15 mg/kg, p.o., twice daily for 2-3 weeks) hydrochloride significantly enhances the anti-PD-1 effect in mice breast cancer model[1].
MAX-40279 (p.o., single dose) hydrochloride has much higher drug concentration in bone marrow than in plasma in SD rats[2].

Animal Model: Micro patient-derived xenotransplantation model established in 5-week-old nu/nu mice[1]
Dosage: 12 mg/kg
Administration: Oral administration (p.o.), once daily for 7 days
Result: Reduced the vitality of tumor cells.
The growth rates of tumour volume and weight were smaller but that the combined inhibition was more remarkable.
Animal Model: MV4-11 and KG-1 cells induced xenograft model established in immunodeficient mice[1]
Dosage: 12 mg/kg
Administration: Oral administration (p.o.), once daily for 21-28 days
Result: Significantly inhibited tumor growth, with no significant weight loss or toxicity observed.
Animal Model: 4T1 induced breast cancer model combination with anti-PD-1 established in mice[1]
Dosage: 7, 10 and 15 mg/kg
Administration: Oral administration (p.o.), once daily for 2-3 weeks
Result: Significantly enhanced the efficacy of anti-PD-1 effect, and the combined treatment with anti-PD-1 antibodies yielded the best results.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
