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,

HDAC, Histone deacetylases: Click to Expand ⟱
Source:
Type:
Enzymes involved in regulating gene expression by removing acetyl groups from histones, the proteins around which DNA is wrapped.
-Many cancers exhibit altered expression levels of HDACs, which can contribute to the dysregulation of genes involved in cell growth, survival, and differentiation.
-HDACs can repress the expression of tumor suppressor genes, leading to uncontrolled cell proliferation and survival. This repression can be a key factor in the development and progression of cancer.
-HDAC inhibitors (HDACi) have been developed and are being investigated for their ability to reactivate silenced genes, induce cell cycle arrest, and promote apoptosis in cancer cells.
-HDAC1, HDAC2): Often overexpressed in various cancers, including breast, prostate, and colorectal cancers. Their overexpression is associated with poor prognosis.
-HDAC4, HDAC5): These may have both oncogenic and tumor-suppressive roles depending on the context and cancer type.
-While HDACs are not classified as traditional oncogenes, their overexpression and activity can contribute to oncogenic processes.
-HDAC inhibitor works by preventing the removal of acetyl groups from histones, thereby modulating gene expression, influencing cell behavior, and potentially reversing aberrant gene silencing seen in various diseases.
-HDAC inhibitors can help reactivate these genes, thereby inhibiting growth and inducing apoptosis in cancer cells.

1938- PL,    Piperlongumine regulates epigenetic modulation and alleviates psoriasis-like skin inflammation via inhibition of hyperproliferation and inflammation
- Study, PSA, NA - in-vivo, NA, NA
ROS↑, In this study, we demonstrated that piperlongumine (PPL) treatment effectively abrogated the hyperproliferation and differentiation of keratinocytes by inducing ROS-mediated late apoptosis with loss of mitochondrial membrane potential.
Apoptosis↑,
MMP↓,
TumCCA↑, the arrest of cell cycle was found at Sub-G1 phase as a result of DNA fragmentation.
DNAdam↑,
STAT3↓, inhibition of STAT3 and Akt signaling was observed
Akt↓,
PCNA↓, decrease in proliferative markers such as PCNA, ki67, and Cyclin D1 along with anti-apoptotic Bcl-2 protein expression
Ki-67↓,
cycD1↓,
Bcl-2↓,
K17↓, Keratin 17 is a critical regulator of keratinocyte differentiation, and it was found to be downregulated with PPL significantly
HDAC↓, PPL epigenetically inhibited histone-modifying enzymes, which include histone deacetylases (HDACs) of class I (HDAC1–4) and class II (HDAC6)
ROS↑, PPL at 5 and 10 µM concentration increased the reactive oxygen species (ROS) levels and a marked increase in oxidative stress were observed when combined with H2O2
*IL1β↓, Topical IMQ prominently induced the levels of pro-inflammatory cytokines, including IL-1β, IL-6, TNF-α, IL-17, IL-22, and transforming growth factor (TGF)-β, while PPL significantly suppressed these levels
*IL6↓,
*TNF-α↓,
*IL17↓,
*IL22↓,


* indicates research on normal cells as opposed to diseased cells
