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
Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance Ref
1 Wnt / β-catenin signaling ↓ Wnt/β-catenin (↓ β-catenin nuclear program) Growth & stemness suppression Piperine suppresses canonical Wnt signaling and shows anti-cancer effects in colorectal cancer cells (ref)
2 PI3K → AKT survival signaling ↓ PI3K/AKT signaling Reduced survival / increased apoptosis Gastric cancer study concludes piperine inhibits proliferation and induces apoptosis through inhibition of PI3K/Akt signaling (ref)
3 AKT → mTOR axis ↓ Akt/mTOR Anti-growth + anti-migration Piperine downregulates Akt/mTOR signaling with associated inhibition of migration and MMP-9 expression (ref)
4 NF-κB transcriptional program ↓ NF-κB activation Reduced inflammatory / pro-survival gene expression Piperine is reported as a potent inhibitor of NF-κB and related transcription factor activity in melanoma cells (ref)
5 STAT3 → Snail EMT axis ↓ STAT3 / ↓ Snail → ↓ EMT Anti-migration / anti-invasion Piperine inhibits colorectal cancer migration/invasion through a STAT3/Snail-mediated EMT mechanism (ref)
6 Multidrug resistance transporter ABCB1 (P-gp) ↓ P-gp-mediated efflux (chemosensitization) Improved chemo response (MDR reversal) Demonstrates piperine has chemosensitizing activity in P-gp–mediated MDR models (piperine characterized as P-gp substrate/modulator) (ref)
7 ROS / oxidative stress ↑ ROS Upstream stress trigger Piperine induces oxidative stress in cancer cells (ROS increase shown) and links it to growth inhibition/apoptosis (ref)
8 Intrinsic apoptosis (caspase activation) ↑ apoptosis Programmed cell death HeLa study: piperine induces apoptosis in a dose-dependent manner with apoptosis markers reported (ref)
9 Autophagy-dependent cell death (ROS–Akt/mTOR coupling) ↑ autophagy-dependent death (with ↓ Akt/mTOR) Stress-lethal program Colon cancer study: piperine induces autophagy-dependent cell death by increasing ROS and inhibiting Akt/mTOR signaling (ref)
10 Cell-cycle progression ↑ cell-cycle arrest (context-dependent) Proliferation blockade Rectal cancer cell study: piperine impairs cell-cycle progression and produces cytostatic/cytotoxic effects (ref)
11 Migration / invasion (MMP-9 axis) ↓ migration / ↓ MMP-9 Anti-metastatic phenotype Piperine suppresses migration with MMP-9 downregulation and Akt/mTOR inhibition (ref)
12 In vivo chemosensitization (doxorubicin) ↑ doxorubicin sensitivity Enhanced therapeutic efficacy Study evaluates piperine as an adjuvant to enhance doxorubicin sensitivity in triple-negative breast cancer models (ref)
