Kaempferol / AChE Cancer Research Results

KaempF, Kaempferol: Click to Expand ⟱
Features:

Kaempferol = dietary flavonol polyphenol (aglycone; often present as glycosides such as kaempferol-3-O-glucoside). Sources: tea, kale, spinach, capers, broccoli, onions. Primary mechanisms (ranked):
1) PI3K/Akt/mTOR pathway inhibition → ↓ proliferation, ↓ survival signaling (core anti-tumor axis).
2) MAPK modulation (ERK/JNK/p38) → apoptosis or growth arrest (context-dependent).
3) NF-κB suppression → ↓ inflammatory and pro-survival transcription programs.
4) Pro-oxidant ROS induction at higher concentrations → mitochondrial apoptosis signaling.
Bioavailability/PK relevance: Oral absorption modest; extensive phase II metabolism (glucuronidation/sulfation); plasma typically low µM or sub-µM after dietary intake; many in-vitro studies use 10–100 µM (often exceeding achievable systemic exposure without specialized delivery).
Clinical evidence status: largely preclinical (cell + animal); limited human cancer trial data; strongest support in epidemiologic associations rather than interventional oncology RCTs.

Kaempferol—an abundant flavonoid found in various fruits, vegetables, and medicinal herbs—affects cancer cell behavior

Pathways:
-Inhibit the PI3K/Akt signaling
-Modulation of the MAPK pathway (including ERK1/2)
-Inhibit NF-κB Signaling Pathway
-can upregulate or activate p53-dependent pathways
-Inhibitory action on STAT
-Activation of AMPK
-Reduce VEGF
-Can induce oxidative stress in cancer cells (ROS)

Kaempferol — Cancer vs Normal Pathway Effects

Rank Pathway / Axis Cancer Cells (↑ / ↓ / ↔) Normal Cells (↑ / ↓ / ↔) TSF Primary Effect Notes / Interpretation
1 PI3K/Akt/mTOR ↓ proliferation; ↓ survival signaling ↔ / mild ↓ (cytoprotective context) R→G Growth suppression Core mechanistic axis across multiple tumor models (breast, lung, colon, prostate).
2 MAPK (ERK, JNK, p38) ↑ JNK/p38 (pro-apoptotic); ↓ ERK (proliferative) ↔ (dose-dependent) R Apoptosis induction Often stress-activated signaling; balance of ERK vs JNK determines outcome.
3 NF-κB ↓ transcription of inflammatory & anti-apoptotic genes ↓ inflammatory tone R→G Anti-inflammatory / anti-survival Reduces cytokine signaling and tumor microenvironment support pathways.
4 ROS ↑ (high concentration; pro-oxidant apoptosis) ↔ / ↓ (antioxidant at low conc.) P→R Mitochondrial stress Biphasic: antioxidant at dietary levels; pro-oxidant at higher in-vitro doses.
5 NRF2 ↔ / ↓ (context-dependent) ↑ cytoprotective response G Redox adaptation May activate antioxidant genes in normal cells; persistent activation in tumors could support resistance.
6 Intrinsic apoptosis (Bax/Bcl-2, caspases) ↑ Bax; ↓ Bcl-2; ↑ caspase-3/9 ↔ R→G Mitochondrial apoptosis Common downstream convergence of ROS + PI3K suppression.
7 Ca2+ signaling ↑ mitochondrial Ca2+ (subset models) ↔ R Apoptotic amplification Not universal; observed in certain carcinoma lines.
8 HIF-1α / Angiogenesis ↓ HIF-1α; ↓ VEGF (model-dependent) ↔ G Anti-angiogenic potential Observed in hypoxia models; translational impact uncertain.
9 Ferroptosis ↔ (indirect; limited data) ↔ R Redox-linked sensitivity (theoretical) No consistent ferroptosis signature established.
10 Clinical Translation Constraint Low oral bioavailability; rapid conjugation; in-vitro concentrations commonly exceed systemic exposure; limited human interventional oncology data. — PK / Evidence Dietary intake likely below cytotoxic range; delivery systems (nano-formulations) under investigation.

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
