Ingenol Mebutate (Ingenol 3-angelate) is an active ingredient in Euphorbia peplus, acting as a potent PKC activator, with K_is of 0.3, 0.105, 0.162, 0.376, and 0.171 nM for PKC-α, PKC-β, PKC-γ, PKC-δ, and PKC-ε, respectively. Ingenol Mebutate also EC₅₀s of 13 ± 2.4 nM (PKC-α), 4.37 ± 0.4 nM (PKC-βI), 10.5 ± 2.2 nM (PKC-βII), 38.6 ± 2.9 nM (PKC-δ), 1.08 ± 0.01 nM (PKC-ε), 0.9 ± 0.13 nM (PKC-μ) in WEHI-231 cells, 198 ± 12.5 nM (PKC-α), 69.1 ± 8.2 nM (PKC-βI), 4.6 ± 0.4 nM (PKC-ε) and 1 nM (PKC-μ) in HOP-92 cells, 635 ± 245 nM (PKC-α), 146 ± 35 nM (PKC-βI), 4.7 ± 0.7 nM (PKC-δ), 1.1 ± 0.5 nM (PKC-ε), and 30 nM (PKC-μ) in Colo-205 cells. Ingenol Mebutate sensitizes WEHI-231 cells, HOP-92 and Colo-205 cells, with IC₅₀s of 1.41 ± 0.255 nM, 3.24 ± 2.01 nM, and 11.9 ± 1.307 nM, respectively^[1]. Ingenol Mebutate (PEP005; 20 nM) actions are PKC-δ dependent, induces apoptosis in primary AML marrow blasts but not in normal myeloblasts^[2]. Ingenol Mebutate (PEP005) activates PKCδ and inhibits PKCα. Colo205-R cells (IC₅₀: >10 μM) are >300-fold more resistant to Ingenol Mebutate than parental Colo205-S cells^[3].

KG1a cells are transiently transfected with EGFP-tagged mouse PKC-δ subcloned into pEGFP-N1 plasmid using an Amaxa nucleofection apparatus. Cells are treated with Ingenol Mebutate (0.2 μM-20 μM) 24 hours after transfection. Cell viability in EGFP-positive cells is assessed and loss of viability confirmed in the total cell culture by MTT assay after 3 days. Briefly, 24 hours after transfection, 2 × 10⁴ cells are plated in 5 wells in 96-well plates and exposed to 0, 0.2, 2, and 20 μM Ingenol Mebutate. At 72 hours, 20 μL MTT substrate at 5 mg/mL is added and plates are incubated at 37°C. After 3 hours, 150 μL media is removed and replaced with 200 μL dimethyl sulfoxide (DMSO). Absorbance at an optical density (OD) of 550 nm is read on a plate reader and corrected for absorbance obtained from blank media controls^[2].
