PL, Piperlongumine: Click to Expand ⟱
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
Pathways:
- induce ROS production in cancer cells likely at any dose. Effect on normal cells is inconclusive.
- ROS↑ related: MMP↓(ΔΨm), ER Stress↑, UPR↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, Prx,
- Lowers some AntiOxidant markers/ defense in Cancer Cells: but mostly raises NRF2 (raises antiO defense), TrxR↓(*important), GSH↓ Catalase↓ HO1↓ GPx↓
- Very little indication of raising AntiOxidant defense in Normal Cells: GSH↑,
- lowers Inflammation : NF-kB↓, COX2↓, conversely p38↑, Pro-Inflammatory Cytokines : NLRP3↓, IL-1β↓, TNF-α↓, IL-6↓, IL-8↓
- inhibit Growth/Metastases : TumMeta↓, TumCG↓, EMT↓, MMP2↓, MMP9↓, VEGF↓, NF-κB↓, CXCR4↓, ERK↓
- reactivate genes thereby inhibiting cancer cell growth : HDAC↓(few reports), DNMT1↓, DNMT3A↓, EZH2↓, P53↑, HSP↓, Sp proteins↓,
- cause Cell cycle arrest : TumCCA↑, cyclin D1↓, CDK2↓, CDK4↓, CDK6↓,
- inhibits Migration/Invasion : TumCMig↓, TumCI↓, ERK↓, EMT↓,
- small indication of inhibiting glycolysis : HIF-1α↓, cMyc↓, LDH↓, HK2↓,
- inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, EGFR↓,
- Others: PI3K↓, AKT↓, JAK↓, STAT↓, β-catenin↓, ERK↓, JNK,
- Synergies: chemo-sensitization, RadioSensitizer, Others(review target notes), Neuroprotective, Cognitive, Hepatoprotective, CardioProtective,

DNMT1, DNA (cytosine-5-)-methyltransferase 1: Click to Expand ⟱
Source: CGL-Driver Genes
Type: Oncogene
DNMT1 overexpression in various cancer types.
DNA (cytosine-5-)-methyltransferase 1, commonly referred to as DNMT1, is an enzyme that plays a crucial role in the maintenance of DNA methylation patterns.
Increased DNMT1 activity can promote tumorigenesis by facilitating the accumulation of methylation changes that drive cancer progression.
Is frequently overexpressed in a variety of cancers, including breast, colorectal, lung, prostate, and hematological malignancies. This overexpression is often associated with hypermethylation of tumor suppressor genes, leading to their silencing and contributing to tumorigenesis.

2958- PL,    Natural product piperlongumine inhibits proliferation of oral squamous carcinoma cells by inducing ferroptosis and inhibiting intracellular antioxidant capacity
- in-vitro, Oral, HSC3
TumCP↓, proliferation rate of PL-treated OSCC cells were decreased in a dose- and time-dependent manner.
lipid-P↑, Lipid peroxidation (LPO) and intracellular reactive oxygen species (ROS) were accumulated after PL treatment.
ROS↑,
DNMT1↑, expression of DMT1 increased, and the expression of FTH1, SLC7A11 and GPX4 decreased.
FTH1↓,
GPx4↓,
eff↓, effect of PL on OSCC cells can be reversed by iron scavengers and antioxidants
GSH↓, PL can inhibit the synthesis of intracellular GSH to induce ferroptosis
Ferroptosis↑,
MDA↓, content of MDA decreased
