QC, Quercetin: Click to Expand ⟱
Features:
Plant pigment (flavonoid) found in red wine, onions, green tea, apples and berries.
Quercetin is thought to contribute to anticancer effects through several mechanisms:
-Antioxidant Activity:
-Induction of Apoptosis:modify Bax:Bcl-2 ratio
-Anti-inflammatory Effects:
-Cell Cycle Arrest:
-Inhibition of Angiogenesis and Metastasis: (VEGF)

Cellular Pathways:
-PI3K/Akt/mTOR Pathway: central to cell proliferation, survival, and metabolism.
-MAPK/ERK Pathway: influencing cell proliferation, differentiation, and apoptosis.
-NF-κB Pathway: downregulate NF-κB
-JAK/STAT Pathway: interfere with the activation of STAT3
-Apoptotic Pathways: intrinsic (mitochondrial) and extrinsic (death receptor-mediated) pathways

Quercetin has been used at doses around 500–1000 mg per day
Quercetin’s bioavailability from foods or standard supplements can be low.

-Note half-life 11 to 28 hours.
BioAv low 1-10%, poor water-solubility, consuming with fat may improve bioavialability. also piperine or VitC.
Pathways:
- induce ROS production in cancer cells (higher dose). Typicallys Lowers ROS in normal cells(unless it is high dose?)or depends on Redox status?. "quercetin paradox"

AChE, acetylcholinesterase: Click to Expand ⟱
Source:
Type:
AChE is an enzyme that rapidly hydrolyzes the neurotransmitter acetylcholine into choline and acetate, terminating cholinergic signals.
- In some cancers, studies have reported reduced AChE activity, which may contribute to an accumulation of acetylcholine.
- Lower levels or loss of AChE expression/activity have been associated with more aggressive tumor behavior and poor prognosis, possibly due to unchecked cholinergic signaling.

For AD (Alzheimer's), AChE inhibitors are used, to allow ACh, and ChAT to increase along with acetyl-CoA
-Natural AChE inhibitors: Ferulic Acid, Caffeic Acid, Rosmarinic Acid, Sage
-AChE inhibitors only temporarily relieve some of the disease’s cognitive symptoms and do not stop the patient’s cognitive loss
-adverse effects such as disorientation, falls, dizziness, and fatigue may occur with these medications and should be used only as recommended
