Alpha-Lipoic-Acid / Sepsis Cancer Research Results

ALA, Alpha-Lipoic-Acid: Click to Expand ⟱
Features: antioxidant, energy production in cell mitochondria
Alpha-Lipoic-Acid: also known as lipoic acid or thioctic acid (reduced form is dihydrolipoic acid).
"Universal antioxidant" because it is both water- and fat-soluble and can neutralize free radicals.
-Treatment sometimes as ALA/N (alpha-lipoic acid/low-dose naltresone)
-Also done in IV
-Decreases ROS production, but also has pro-oxidant role.
Normal adult can take 300 milligrams twice a day with food, but they should always take a B-complex vitamin with it. Because B complex vitamins, especially thiamine, and biotin, and riboflavin, are depleted during this metabolic process.
α-Lipoic acid acts as a chelating agent for metal ions, a quenching agent for reactive oxygen species, and a reducing agent for the oxidized form of glutathione and vitamins C and E.
-It seems a paradox that LA functions as both antioxidant and prooxidant. LA functions the pro-oxidant only in special cancer cells, such as A549 and PC9 cells which should show high-level NRF2 expression and high glycolytic level. Through inhibiting PDK1 to further prohibit NRF2; LA functions as anticancer prooxidant.

α-lipoic acid possesses excellent silver chelating properties.

ALA → ROS ↑ (cancer cells; high dose / stressed mitochondria)
ALA → ROS ↓ (normal cells; low–moderate dose)
same pattern seen with: Vitamin C, Menadione, Quercetin, EGCG, Resveratrol
- ALA acts as pro-Oxidant only in cancer cells:#278 - Pro-Oxidant Dose margin >100uM:#304

- Bioavailability: 80-90%, but conversion to EPA/DHA is 5-10% (and takes longer time).
- AI (Adequate Intake): 1.1-1.6g/day.
- human studies have shown that ALA levels decline significantly with age
- 1g of ALA might achieve 500uM in the blood.
- ALA is poorly soluble, lecithin has been used as an amphiphilic matrix to enhance its bioavailability.
- Pilot studies or observational interventions have used flaxseed supplementation (rich in ALA) in doses providing roughly 3–4 g of ALA daily.
- Flaxseed oil is even more concentrated in ALA – typical 50–60% ALA by weight.
- single walnut may contain 300mg of ALA
- chia oil contains 55-65% ALA.
- α-LA can also be obtained from the diet through the consumption of dark green leafy vegetables and meats
- ALA is more stable in chia seeds, (2grams of ALA per tablespoon)
- ALA degrades when exposed to heat, light, and air. (prone to oxidation)

-Note half-life 1-2 hrs.
BioAv 30-40% from walnuts, 60-80% from supplements. Co-ingestion with fat improves absorption. Both fat and water soluble

- Selectivity: Cancer Cells vs Normal Cells

Cancer-Relevant Pathways
Rank Pathway / Axis Cancer Cells Normal Cells Label Interpretation Notes
1 Reactive oxygen species (ROS) ↑ ROS (dose- & stress-dependent) ↓ ROS Conditional Driver Biphasic redox behavior ALA/DHLA redox cycling can push already stressed cancer mitochondria past tolerance while buffering ROS in normal cells
2 Glutathione (GSH) system ↓ functional buffering ↑ GSH regeneration Secondary Redox amplification vs protection In cancer cells, GSH consumption accompanies ROS escalation; in normal cells DHLA supports GSH recycling
3 Mitochondrial function (ΔΨm) ↓ ΔΨm (stress-induced) ↔ stabilized Secondary Mitochondrial selectivity Cancer cells with unstable ETC show depolarization; normal cells tolerate or benefit metabolically
4 NF-κB signaling ↓ survival signaling ↓ inflammatory tone Secondary Redox-sensitive transcription NF-κB suppression reduces cancer cell survival programs but is anti-inflammatory in normal tissue
5 Cell proliferation ↓ proliferation ↔ spared Phenotypic Cytostatic selectivity ALA slows cancer cell cycling without universal apoptosis
6 Apoptosis ↑ apoptosis (conditional) ↓ apoptosis Phenotypic Threshold-dependent death Occurs in cancer cells when redox stress exceeds buffering capacity
7 NRF2 antioxidant response ↑ NRF2 (adaptive, often insufficient) ↑ NRF2 (protective) Adaptive Stress compensation NRF2 reflects attempted redox recovery; not a kill mechanism


Sepsis, Sepsis: Click to Expand ⟱
Source:
Type:
Sepsis is a life-threatening medical condition that occurs when the body’s response to an infection causes widespread inflammation. This uncontrolled inflammatory response can lead to tissue damage, organ failure, and, in severe cases, death.

-Treatment options PKM2, Glycolysis and HIF1α inhibitors.

-Chemotherapy, radiation therapy, and immunosuppressive drugs can further weaken the immune system, making patients more susceptible to infections that can lead to sepsis.

-AgNPs have demonstrated antimicrobial effects against a wide range of pathogens including bacteria, fungi, and viruses. Since infections are the primary trigger for sepsis, their ability to reduce microbial loads has been of significant interest.
