CHr, Chrysin: Click to Expand ⟱
Features:
Chrysin is found in passion flower and honey. It is a flavonoid.
-To reach plasma levels that might more closely match the concentrations used in in vitro studies (typically micromolar), considerably high doses or advanced delivery mechanisms would be necessary.
Chrysin is widely summarized as modulating PI3K/Akt and MAPK pathways in cancer.

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Axis Cancer Cells Normal Cells TSF Primary Effect Notes / Interpretation
1 PI3K → AKT (± mTOR) survival axis ↓ PI3K/AKT (often ↓ p-AKT; downstream growth signals ↓) ↔ R, G Growth/survival suppression Frequently reported hub effect; contributes to reduced proliferation and sensitization to stress/apoptosis programs.
2 Intrinsic apoptosis (p53/Bcl-2 family → caspase-9/3) ↑ p53 axis (context); Bax↑/Bcl-2↓; ↑ caspase-9/3; apoptosis ↑ ↔ (generally less activation) G Apoptosis execution Common endpoint across many tumor models; often downstream of survival-pathway suppression and stress signaling.
3 ER stress / UPR (PERK and related arms) ER stress ↑; UPR activation ↑ ↔ R, G Stress-to-death coupling ER stress has been directly shown in chrysin-treated cancer cells and can couple to apoptosis.
4 JAK / STAT3 signaling ↓ STAT3 signaling (context) ↔ R, G Anti-survival transcription STAT3 inhibition is reported in cancer models and often aligns with reduced proliferation and increased apoptosis.
5 ROS / oxidative stress (context-dependent) ROS modulation (often ↑ mitochondrial ROS in tumor models) ↔ / antioxidant behavior in some contexts P, R, G Stress amplifier (variable) Direction depends on dose/model; avoid absolute “ROS always ↑/↓”. Oxidative stress + DDR has been linked to anti-angiogenic effects in vivo in melanoma models.
6 MAPK re-wiring (ERK / JNK / p38) MAPK shifts; JNK/p38 often stress-activated; ERK variable ↔ P, R, G Signal reprogramming MAPK effects differ by cell line; chrysin can suppress JNK/ERK signaling to reduce MMP-9 in some models.
7 Cell-cycle arrest / proliferation control Cell-cycle arrest ↑; proliferation ↓ ↔ G Cytostasis Often observed as later phenotype-level outcomes, downstream of signaling changes.
8 Invasion / metastasis (MMP-9; EMT programs) MMP-9 ↓; migration/invasion ↓ (context) ↔ G Anti-invasive phenotype Chrysin can reduce MMP-9 expression via AP-1 suppression and MAPK pathway effects in certain cancer models.
9 Angiogenesis (VEGF/angiogenic outputs) Angiogenesis outputs ↓ (context) ↔ G Anti-angiogenic support In melanoma models, chrysin has been associated with angiogenesis regression linked to oxidative stress and DNA damage response.
10 Bioavailability constraint (oral PK limitation) Systemic exposure often low without formulation — — Translation constraint Native chrysin oral bioavailability is extremely low due to poor solubility and extensive glucuronidation/sulfation with efflux; formulation strategies are commonly required for systemic effects.

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

  • P: 0–30 min (primary/physical–chemical effects; rapid signaling / phosphorylation shifts)
  • R: 30 min–3 hr (acute stress-response and redox signaling)
  • 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

Tier A — Direct LDH Enzyme Inhibitors (Validated Catalytic Inhibition)

Rank Compound Type LDH Target Potency Level Primary Effect Notes
1 NCI-006 Research drug LDHA / LDHB High (in vivo active) Potent glycolysis suppression Modern benchmark LDH inhibitor used in metabolic oncology models.
2 (R)-GNE-140 Research drug LDHA (±LDHB) High (nM range reported) Lactate production ↓ Widely used experimental LDH inhibitor.
3 FX11 Research drug LDHA High (μM range) Metabolic crisis in LDHA-dependent tumors Classic LDHA inhibitor; often increases ROS secondary to metabolic stress.
4 Oxamate Tool compound LDH (pyruvate-competitive) Moderate (mM cellular use) Reduces lactate flux Classical LDH inhibitor; requires high concentrations in cells.
5 Gossypol Natural product derivative LDHA Moderate–High Glycolysis inhibition Also has other targets; safety considerations apply.
6 Galloflavin Natural compound LDH isoforms Moderate Lactate production ↓ One of the better-supported “natural-like” LDH inhibitors.

Tier B — Indirect LDH-Axis Modulators (Glycolysis / Lactate Reduction Without Confirmed Direct Catalytic Inhibition)

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.
