YO-2
YO-2 is a plasmin inhibitor and TP53 upregulator with anti-tumor and apoptosis-inducing activities. YO-2 upregulates the expression of TP53 and the tumor-suppressive miR-103/107, downregulates LRP1, and induces cellular DNA fragmentation and caspase cascade activation. YO-2 effectively blocks the growth of melanoma. YO-2 has been widely used in studies related to melanoma and colon cancer.

Biological Activity
YO-2 (10-30 μM; 24 h) dose-dependently inhibits plasminogen-induced proliferation of murine B16F10 melanoma cells after 24 h of incubation[1].
YO-2 (10-30 μM; 24 h) dose-dependently activates caspase 3/7 in murine B16F10 melanoma cells, with a ~10-fold increase in activity at 30 μM after 24 h of incubation[1].
YO-2 (10-30 μM; 24 h) dose-dependently downregulates anti-apoptotic BCL2 gene expression in murine B16F10 melanoma cells after 24 h of incubation[1].
YO-2 (10-20 μM) increases p53 protein levels in murine B16F10 melanoma cells at concentrations of 10 μM and 20 μM[1].
YO-2 (10-30 μM) dose-dependently upregulates p53 protein levels in murine B16F10 melanoma cells at concentrations of 10 μM, 20 μM, and 30 μM[1].
YO-2 (30 μM; 1-6 h) induces apoptotic morphological changes in rat thymocytes, including time-dependent phosphatidylserine translocation and chromatin condensation, when treated with 30 μM YO-2 for 1 to 6 h[2].

Cell Line:murine B16F10 melanoma cells
-
Concentration:10-30 μM
-
Incubation Time:24 h
-
Result:Increased caspase 3/7 activity in a dose-dependent fashion.
Induced a ~3-fold increase at 10 μM compared to PBS-treated controls.
Induced a ~6-fold increase at 20 μM compared to PBS-treated controls.
Induced a ~10-fold increase at 30 μM compared to PBS-treated controls.
Cotreatment with YO-2 (5 mg/kg; i.p.; every other day; starting day 5 post-tumor inoculation) and a single 1 mg/kg dose of Doxorubicin (HY-15142A) (day 0 post-tumor inoculation) significantly reduces melanoma tumor weight more effectively than either agent alone in a murine subcutaneous melanoma model[1].
YO-2 (5 mg/kg; i.p.; daily; starting day 5 post-tumor inoculation) significantly reduces tumor weight in mice bearing LRP1-overexpressing subcutaneous melanoma tumors[1].
