Features:

Compound of black pepper that boosts bioavailability of curcumin

piperine’s bioenhancing function, often more important than piperine’s direct anticancer activity

Mechanisms of bioenhancement
| Mechanism                     | Effect                             |
| ----------------------------- | ---------------------------------- |
| **↓ CYP3A4, CYP2C9**          | Slows metabolic clearance          |
| **↓ UGT (glucuronidation)**   | Increases parent compound exposure |
| **↓ P-glycoprotein (ABCB1)**  | Improves intracellular retention   |
| **↑ Intestinal permeability** | Better oral absorption             |

-Curcumin: ↑ bioavailability ~20–30×
-Resveratrol, EGCG, quercetin: ↑ exposure 2–10×

Primary pathways: NF-κB, STAT3, PI3K/Akt/mTOR, apoptosis, EMT
Direct anticancer potency: modest
Bioenhancing value: central and often dominant

Type:

Plays a key role in activation of cellular immunity and subsequently, stimulation of antitumor immune-response. Based on its cytostatic, pro-apoptotic and antiproliferative functions, IFN-γ is considered potentially useful for adjuvant immunotherapy for different types of cancer.
Moreover, it IFN-γ may inhibit angiogenesis in tumor tissue, induce regulatory T-cell apoptosis, and/or stimulate the activity of M1 proinflammatory macrophages to overcome tumor progression.
However, the current understanding of the roles of IFN-γ in the tumor microenvironment (TME) may be misleading in terms of its clinical application.

IFN-γ is often expressed in the tumor microenvironment, particularly in response to immune cell infiltration. Its expression can be influenced by the presence of tumor-infiltrating lymphocytes (TILs) and other immune cells.
High levels of IFN-γ are typically associated with a Th1 immune response, which is generally considered beneficial for anti-tumor immunity.

Tumor Suppression:
In many cases, IFN-γ has tumor-suppressive effects, as it can inhibit tumor cell proliferation and induce apoptosis in certain cancer types.
