SU212 is a podophyllotoxin-derived ENO1 inhibitor and AMPK activator. SU212 can selectively induce oxidative phosphorylation, reduce glycolysis activity and glucose uptake in tumor cells, and directly bind to ENO1 without affecting these pathways in normal cells. SU212 induces apoptosis and promotes ENO1 degradation via proteasomal and autophagic pathways without inhibiting the catalytic activity. SU212 leads to mitotic arrest and apoptosis in TNBC (triple-negative breast cancer) cells by activating AMPK, demonstrating potent anti-tumor activity in vitro. SU212 inhibits tumor growth and metastasis in syngeneic, xenograft, and diabetic mouse models, exhibiting an excellent safety profile. SU212 can be used in research on t TNBC, diabetes, and fatty liver disease.

SU212 is a podophyllotoxin-derived ENO1 inhibitor and AMPK activator. SU212 can selectively induce oxidative phosphorylation, reduce glycolysis activity and glucose uptake in tumor cells, and directly bind to ENO1 without affecting these pathways in normal cells. SU212 induces apoptosis and promotes ENO1 degradation via proteasomal and autophagic pathways without inhibiting the catalytic activity. SU212 leads to mitotic arrest and apoptosis in TNBC (triple-negative breast cancer) cells by activating AMPK, demonstrating potent anti-tumor activity in vitro. SU212 inhibits tumor growth and metastasis in syngeneic, xenograft, and diabetic mouse models, exhibiting an excellent safety profile. SU212 can be used in research on t TNBC, diabetes, and fatty liver disease[1][2].

In Vitro

SU212 (0.01-850 μM, 48 h) demonstrates lower toxicity and higher potency against TNBC cells (MDA-MB-231) than Etoposide with an IC50 of 0.26 μM; inhibits 50% cell viability in human TNBC cells with IC50s values of 0.1, 0.24, and 0.037 μM for MDA-MB-468, SUM159, and BT549 respectively, and in mouse TNBC cell lines with IC50 values of 0.85, 0.18, 0.039, and 0.31 μM for 4T1, EMT6, E0771, and PY8119[1][2].
SU212 (0.5 μM, 6 h) has a different target than Etoposide in MDA-MB-231 cells and promotes ENO1 degradation through both proteasomal and autophagic pathways; this effect is partially blocked by co-treatment with MG132 or 3MA[1].
SU212 (0.1-10 μM, 3 min-6 h) increases the thermal stability of both ENO1 and ENO3 and stronger interaction with ENO1 cells and exhibits a dose-dependent in multiple TNBC cell lines (MDA-MB-231, MDA-MB-468, and EMT6[1].
SU212 (0.25 or 0.5 μM, 1.5 h) inhibits the overall oxygen consumption rate, extracellular acidification rate, and glycolytic rate in MDA-MB-231, MCF12A, and HEK293 cells, without affecting the glycolytic rate or viability of normal cells[1].

SU212 (0.25 μM-0.5 μM, 30 min-6 h) inhibits lactate production and decreases the cellular in MDA-MB-468 and MDA-MB-231, not affect the cellular level of D-glucose, glucose-6-phosphate/fructose-6-phosphate, ATP, citrate, OCR and ECAR α-ketoglutarate in MDA-MB-231 cells[2].
SU212 (0.5 μM, 12 h) significantly increases in the levels of proteins associated with oxidative phosphorylation, decreases the levels of proteins associated with glycolysis and the pentose phosphate pathway in MDA-MB-231 and MDA-MB-468 cell lines but not in normal breast cell lines[2].
SU212 (0.1-0.5 μM, 6 or 72 h) has cytotoxic effect that dependent on AMPK activation in MDA-MB-468 and MDA-MB-231[2].
SU212 (0.2-0.6 μM, 48 h) activates AMPK independent of energy stress in TNBC cell lines[2].

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.
