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 to 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.

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.
