**Background**
Protein kinase C (PKC) is a family of serine/threonine kinases that play critical roles in regulating various cellular processes, including signal transduction, cell growth, differentiation, and apoptosis. Dysregulation of PKC signaling is frequently implicated in the progression of various malignancies, making it a significant target for therapeutic intervention. In the context of oncology, modulating PKC activity can induce antitumor responses and alter the microenvironment of tumor cells. Understanding the specific interactions between small molecules and PKC is essential for developing effective treatments for Ingenol cancer research. Therefore, we will introduce a PKC activator – Ingenol.
**Definition**
Ingenol is a diterpenoid compound that acts as a PKC activator with a Ki value of 30 μM.
**In Vitro Studies**
Regarding the Ingenol description, this compound is classified as a terpenoid diterpenoid initially sourced from plants of the Gramineae family, specifically Leptochloa chinensis. In terms of Ingenol in vitro activity, it has been demonstrated to induce ornithine decarboxylase activity at concentrations of 1–3 mM and cause morphological changes in primary mouse epidermal keratinocytes at 1 mM. Furthermore, Ingenol inhibits cell-cell communication at concentrations ranging from 125 μM to 1 mM. In human primary epidermal keratinocytes, Ingenol (Compound 2) induces the release of IL-8 and TNFα with an EC50 of 10,000 nM after 6 hours of treatment. Additionally, studies on MT4 cells showed that related derivatives exhibit antiviral activity against HIV-1 and HIV-2, while the parent compound demonstrates an IC50 > 20 μM for the inhibition of LPS-induced nitric oxide production in mouse RAW264.7 cells. In Vero cells, antiviral activity against the chikungunya virus was observed with an EC50 of 30.1 μM. In conclusion, Ingenol is a PKC activator with diverse biological activities across various cell types, including antitumor and anti-inflammatory properties.
