Mechanism of Action

Features	Multi-functional molecule: multi-target, anti-proliferative, pro-apoptotic activity, and anti-angiogenic activity.
Targets/IC₅₀/Ki	FLT3 1.86 nM RET 10.4 nM Aurora A 14 nM VEGFR3/FLT4 15.9 nM Src 20.2 nM NTRK1/TRKA 24.2 nM CSF-1R/c-Fms 24.8 nM LCK 43.7 nM FAK 54.9 nM PDGFRα 56.4 nM VEGFR2/KDR 58.2 nM BLK 69.4 nM FGFR2 70.8 nM YES1 78.4 nM Abl1 (T315I) 81.3 nM FGFR1 92.7 nM Fyn 112 nM JAK2 120 nM Kit 120 nM Aurora B 350 nM
In vitro	ENMD-2076 indicates activity against multiple kinases involved in angiogenesis, including FLT3, RET, FLT4/VEGFR3, SRC, NTRK1, CSF1R/FMS, LCK, VEGFR2/KDR, FGFR1/2, and PDGFRα with IC50 from 1.86-120 nM. ENMD-2076 inhibits the growth of a wide range of human solid tumor and hematopoietic cancer cell lines with IC50 from 0.025-0.7 μM, which induces apoptosis and G2/M phase arrest. ENMD-2076 induces regression or complete inhibition of tumor growth in tumor xenograft models derived from breast, colon, melanoma, leukemia, and multiple myeloma cell lines. ENMD-2076 is the L (+) tartrate salt of ENMD-981693. ENMD-2076 shows significant cytotoxicity against myeloma cell lines (IM9, ARH-77, U266, RPMI 8226, MM.1S, MM.1R, NCI-H929) and primary cells with IC50 from 2.99 to 7.06 μM, which induces apoptosis. ENMD-2076 indicates low cytotoxicity to haematopoietic progenitors. ENMD-2076 inhibits the phosphoinositide 3-kinase/Akt pathway and downregulates survivin and X-linked inhibitor of apoptosis. ENMD-2076 also inhibits aurora A and B kinases, and induces G2/M cell cycle arrest.
Kinase Assay	Kinase assays
Kinase Assay	Recombinant Aurora A and B kinase enzymes and appropriate PanVera Z'-Lyte kinase assay kits are purchased. Assays are carried out in kinase assay buffer (50 mM of HEPES, pH 7.5, 10 mM of MgCl₂, 5 mM of EGTA, 0.05% Brij-35) supplemented with 2 mM of DTT. Activities are determined at an ATP concentration equivalent to the apparent Km for each enzyme, and an enzyme concentration that results in approximately 30% phosphorylation of the peptide substrate after 1 hour. Dose–response curves of relative enzyme activity versus ENMD-2076 concentration are plotted with Grafit and used to calculate IC50 values. Potency of ENMD-2076 free base against a select panel of 100 kinase enzymes is determined using the SelectScreen kinase profiling service. ATP concentrations are at the apparent Km for each enzyme or 100 μM if the apparent Km could not be reached. Percent inhibition is determined at an ENMD-2076 free base concentration of 1 μM; for kinases where significant inhibition is noted, IC50 values are determined by generating full 10-point dose–response curves.
In vivo	ENMD-2076 has sustained inhibitory effects on the activation of Flt3 as well as VEGFR2/KDR and FGFR1/2 in HT29 xenograft model. ENMD-2076 could prevent the formation of new blood vessels and regress formed vessels in MDA-MB-231 xenograft model. Oral treatment with ENMD-2076 (50, 100, 200 mg/kg per day) inhibits the tumour growth in H929 human plasmacytoma xenografts, with significant reduction in phospho-Histone 3 (pH3), Ki-67, and angiogenesis, and also a significant increase in cleaved caspase-3.
