Features:
Piperlongumine (also called Piplartine), an alkaloid from long pepper fruit
-Piperlongumine is a bioactive alkaloid derived from the long pepper (Piper longum)
– Piperlongumine has been shown to selectively increase ROS levels in cancer cells.
-NLRP3 inhibitor?
-TrxR inhibitor (major antioxidant system) to increase ROS in cancer cells
-ic50 cancer cells maybe 2-10uM, normal cells maybe exceeding 20uM.

Available from mcsformulas.com
-(Long Pepper, 500mg/Capsule)- 1 capsule 3 times daily with food
-Piperlongumine Pro Liposomal, 40 mg-take 1 capsule daily with plenty of water, after a meal

-Note half-life 30–60 minutes
BioAv poor aqueous solubility and bioavailability

- Selectivity: Cancer Cells vs Normal Cells
Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance Ref
1 Transformation-linked oxidative stress dependence ↑ ROS Cancer-selective stress overload Landmark study: piperlongumine selectively kills cells with a cancer genotype by elevating ROS; antioxidant rescue blocks killing (ref)
2 GSTP1 redox buffering (glutathione S-transferase π) ↓ GSTP1 function / ↑ ROS Disables antioxidant buffering Biochemical/structural work describing GSTP1 as a piperlongumine target and linking PL exposure to increased ROS and decreased GSH (ref)
3 ER stress / UPR via PRDX4 (Peroxiredoxin 4) ↓ PRDX4 activity / ↑ ER stress Proteotoxic stress, preferential glioma killing Piperlongumine inactivates PRDX4, exacerbates ER stress, increases ROS, and preferentially kills high-grade glioma cells (ref)
4 Mitochondrial disruption + stress MAPK (JNK) ↓ ΔΨm / ↑ JNK Mitochondrial apoptosis signaling Example mechanistic paper: piperlongumine induces ROS-mediated mitochondrial disruption and activates JNK associated with apoptosis (ref)
5 DNA damage response ↑ DNA damage Checkpoint activation, death signaling Piperlongumine elevates ROS and causes DNA damage in pancreatic cancer models; antioxidant reverses DNA damage and killing (ref)
6 STAT3 signaling ↓ STAT3 activity (↓ pSTAT3 / ↓ STAT3 function) Reduced survival & stem-like growth Drug-repositioning study identifies piperlongumine as a direct STAT3 inhibitor; shows reduced STAT3 activation and mammosphere inhibition (ref)
7 NF-κB signaling ↓ NF-κB DNA binding / ↓ nuclear translocation Reduced inflammatory & anti-apoptotic transcription Piperlongumine down-regulates NF-κB DNA-binding activity and decreases nuclear translocation of p50/p65 in prostate cancer cells (ref)
8 PI3K–AKT–mTOR pathway ↓ PI3K/AKT/mTOR signaling Growth suppression; promotes apoptosis/autophagy Paper explicitly reporting piperlongumine induces apoptosis and autophagy through inhibition of PI3K/Akt/mTOR in lung cancer cells (ref)
9 p38 signaling (stress kinase) ↑ p38 signaling Stress response; autophagy involvement Mechanistic study showing piperlongumine induces autophagy by targeting p38 signaling (ref)
10 Cell cycle regulation ↑ G2/M arrest Proliferation block Demonstrates piperlongumine induces G2/M cell-cycle arrest in MCF-7 cells (cell cycle distribution shift shown) (ref)
11 EMT / migration / invasion ↓ EMT / ↓ migration & invasion Anti-metastatic phenotype Reports piperlongumine inhibits TGF-β–induced EMT and reduces migration/invasion in cancer cells (ref)
12 Ferroptosis (iron-dependent oxidative death) ↑ ferroptosis Non-apoptotic killing modality Shows piperlongumine-induced cancer cell death is inhibited by ferroptosis inhibitors and iron chelation, supporting ferroptosis involvement (ref)


TumCCA, Tumor cell cycle arrest: Click to Expand ⟱
Source:
Type:
Tumor cell cycle arrest refers to the process by which cancer cells stop progressing through the cell cycle, which is the series of phases that a cell goes through to divide and replicate. This arrest can occur at various checkpoints in the cell cycle, including the G1, S, G2, and M phases. S, G1, G2, and M are the four phases of mitosis.
