FA, Ferulic acid: Click to Expand ⟱
Features:
Ferulic acid is an antioxidant found in some skin creams and serums.
Foods: popcorn, bamboo, whole-grain rye bread, whole-grain oat flakes, sweet corn (cooked)
Ferulic acid (FA) is a hydroxycinnamic acid abundant in plant cell walls (notably cereals/whole grains) with strong antioxidant and cytoprotective activity. Mechanistically, FA is frequently described as inducing Nrf2/HO-1 antioxidant programs and suppressing NF-κB-linked inflammation, with additional model-dependent anticancer effects (cell-cycle arrest, apoptosis, reduced invasion). Oral exposure is variable because FA is rapidly metabolized (often as conjugates) and bioaccessibility depends on the food matrix.

-Ferulic acid found in dietary strand fractions, especially its free form, has important functions for protecting the human health.
-AChE inhibitor (AD)
-Cooking results in an increase in free ferulic acid quantity and in a reduction in bound ferulic acid quantity.

Pathway / Target	Modulation by FA / Direction
Aβ aggregation	         ↓ Inhibits fibril formation and destabilizes existing Aβ fibrils 
BACE‑1 & APP	         ↓ Reduces BACE-1 and APP expression; ↑ MMP‑2/‑9 expression promoting Aβ clearance
Tau hyperphosphorylation  Implicitly ↓ through modulation of Ca²⁺/CDK5/GSK3β pathways
Ca²⁺         	         ↓ FA lowers STEP levels via chelation of Ca²⁺, suppressing PP2B → restores synaptic plasticity
(AChE / BChE)	         ↓ Inhibition of AChE (FA IC₅₀~15 µM, derivatives IC₅₀ down to 0.006 µM); also BChE
(MAO‑A/B)	         ↓ Inhibits MAO‑B (derivatives IC₅₀ ~0.3–0.7 µM), reducing ROS
ROS                      ↓ Scavenges ROS, enhances antioxidant enzymes (e.g., catalase), ↓ MDA
(COX‑2, 5‑LOX, NLRP3)	 ↓ Derivatives inhibit COX‑2/5‑LOX; derivative 13a ↓ NLRP3 inflammasome
Iron/Cu²⁺ chelation	 ↓ Metal-induced Aβ aggregation via chelation by FA and derivatives
Autophagy & Aβ clearance  ↗ Suggested promotion of autophagy mechanisms targeting Aβ
Rank Pathway / Axis Cancer Cells Normal Cells TSF Primary Effect Notes / Interpretation
1 Nrf2 → HO-1 / ARE antioxidant response Stress adaptation modulation (context-dependent) Nrf2 ↑; HO-1 ↑; antioxidant defenses ↑ R, G Endogenous antioxidant upshift FA is repeatedly reported to promote Nrf2 nuclear translocation and HO-1 induction; this is one of the most defensible “core” mechanisms.
2 NF-κB inflammatory transcription (COX-2 / iNOS / cytokines) NF-κB ↓; COX-2/iNOS and pro-inflammatory cytokine programs ↓ (reported) Inflammation tone ↓ (tissue protective) R, G Anti-inflammatory signaling Often described as downstream of redox changes and upstream of reduced inflammatory mediators; direction is consistent across many inflammation models.
3 ROS / oxidative stress tone Oxidative stress ↓ (often); ROS direction can vary by tumor model Oxidative injury ↓ P, R, G Redox buffering (context-dependent) FA is classically antioxidant; in tumor systems, effects may be secondary to signaling changes and vary with baseline redox instability.
4 Cell-cycle control (Cyclin D1 / CDK4/6; checkpoints) Cell-cycle arrest ↑ (reported); Cyclin D1 ↓; proliferation ↓ G Cytostasis Frequently reported as later phenotype-level outcomes; direction and checkpoint phase (G1 vs G2/M) vary by model.
5 Apoptosis (intrinsic caspase-linked; p53 axis in some models) Apoptosis ↑; caspase activation ↑ (reported); p53/p21 ↑ (model-dependent) ↔ (generally less activation) G Cell death execution Apoptosis is commonly observed in cancer models but is not as “signature-direct” as for mitochondrial toxins; best treated as downstream/conditional.
6 MAPK re-wiring (ERK / JNK / p38) MAPK modulation (context-dependent) P, R, G Signal reprogramming MAPK direction depends on whether FA is acting primarily as anti-inflammatory/anti-stress vs antiproliferative; avoid hard arrows for p38/JNK/ERK unless model-specific.
7 PI3K → AKT (± mTOR) survival axis PI3K/AKT modulation (reported; model-dependent) R, G Survival/growth modulation Often listed in anticancer summaries; treat as “reported” rather than universal primary mechanism.
8 Invasion / metastasis programs (MMPs / migration) MMPs ↓; migration/invasion ↓ (reported) G Anti-invasive phenotype Observed as later outcomes (gene expression + phenotype assays) and commonly linked to NF-κB/MAPK context.
9 Radiation/chemo injury mitigation (supportive care framing) Adjunct potential: may reduce treatment-associated oxidative/inflammatory injury (context) Tissue protection ↑ (reported) G Cytoprotection Animal models report radioprotective/anti-inflammatory effects; present as supportive/adjunct rather than standalone anticancer therapy.
10 Bioavailability / metabolism constraint (conjugation; food-matrix dependence) Systemic exposure variable; much appears as glucuronide/sulfate conjugates Translation constraint FA is absorbed and rapidly metabolized; “bioavailability” varies widely with food matrix and binding to polysaccharides in grains.

Time-Scale Flag (TSF): P / R / G

  • P: 0–30 min (primary/rapid effects; early redox interactions / rapid signaling shifts)
  • R: 30 min–3 hr (acute stress-response + transcription signaling shifts)
  • G: >3 hr (gene-regulatory adaptation and phenotype-level outcomes)


LDH, Lactate Dehydrogenase: Click to Expand ⟱
Source:
Type:
LDH is a general term that refers to the enzyme that catalyzes the interconversion of lactate and pyruvate. LDH is a tetrameric enzyme, meaning it is composed of four subunits.
LDH refers to the enzyme as a whole, while LDHA specifically refers to the M subunit. Elevated LDHA levels are often associated with poor prognosis and aggressive tumor behavior, similar to elevated LDH levels.
leakage of LDH is a well-known indicator of cell membrane integrity and cell viability [35]. LDH leakage results from the breakdown of the plasma membrane and alterations in membrane permeability, and is widely used as a cytotoxicity endpoint.

However, it's worth noting that some studies have shown that LDHA is a more specific and sensitive biomarker for cancer than total LDH, as it is more closely associated with the Warburg effect and cancer metabolism.

Dysregulated LDH activity contributes significantly to cancer development, promoting the Warburg effect (Chen et al., 2007), which involves increased glucose uptake and lactate production, even in the presence of oxygen, to meet the energy demands of rapidly proliferating cancer cells (Warburg and Minami, 1923; Dai et al., 2016b). LDHA overexpression favors pyruvate to lactate conversion, leading to tumor microenvironment acidification and aiding cancer progression and metastasis.

Inhibitors:
Flavonoids, a group of polyphenols abundant in fruit, vegetables, and medicinal plants, function as LDH inhibitors.
LDH is used as a clinical biomarker for Synthetic liver function, nutrition

Rank Compound Mechanism Type LDH Claim Type Primary Axis Notes / Caution
1 Lonidamine MCT/MPC modulation Lactate axis inhibition Metabolic transport blockade Better classified as lactate/pyruvate transport modulator.
2 Stiripentol Repurposed drug LDH pathway modulation Metabolic axis modulation Emerging oncology interest; primarily neurological drug.
3 Quercetin Flavonoid Reported LDH inhibition (mixed evidence) NF-κB / PI3K modulation Often LDH-release confusion; direct enzymatic proof limited.
4 Ursolic acid Triterpenoid Reported LDH interaction Warburg modulation More credible as metabolic signaling modulator.
5 Fisetin Flavonoid Docking / indirect reports Apoptosis / survival signaling Enzyme inhibition not well validated.
6 Resveratrol Polyphenol Indirect glycolysis suppression AMPK / HIF-1α modulation Reduces lactate via upstream signaling.
7 Curcumin Polyphenol Indirect LDH expression modulation Inflammation + metabolic signaling Bioavailability limits translational strength.
8 Berberine Alkaloid Indirect metabolic modulation AMPK activation Closer to metformin-like metabolic pressure.
9 Honokiol Lignan Indirect glycolysis effects Survival pathway suppression Not validated as catalytic LDH inhibitor.
10 Silibinin Flavonolignan Mixed / indirect reports Inflammation + metabolic axis Often misclassified as LDH inhibitor.
11 Kaempferol Flavonoid Often LDH-release marker confusion Glucose transport / signaling Do not list as direct LDH inhibitor without enzyme data.
12 Oleanolic acid / Limonin / Allicin / Taurine Natural compounds Weak / indirect evidence General metabolic modulation Should not be categorized as true LDH inhibitors.

Tier A = Direct catalytic LDH inhibition (enzyme-level validation).
Tier B = Indirect lactate reduction or glycolytic modulation without strong catalytic inhibition evidence.
Important: LDH release assays (cell damage marker) are not proof of LDH enzymatic inhibition.
