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.

-Note half-life 2 hrs, BioAv very poor often <1%

- 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)

Type:

Cyclin-dependent kinase 4 (CDK4) is a key regulator of the cell cycle, particularly in the transition from the G1 phase to the S phase. Its expression and activity are often altered in various cancers, contributing to tumorigenesis.
CDK4 is frequently overexpressed in various cancers, and its expression levels can serve as a prognostic marker.

Apoptosis↑, apoptosis, disrupting the cell cycle and inhibiting migration without generating toxicity or undesired side‑effects in normal cells
TumCMig↓,
*toxicity↝, toxic at higher doses and the recommended dose for chrysin is <3 g/day
ChemoSen↑, chrysin also inhibits multi‑drug resistant proteins and is effective in combination therapy
*BioAv↓, extremely low bioavailability in humans due to rapid quick metabolism, removal and restricted assimilation. The bioavailability of chrysin when taken orally has been estimated to be between 0.003 to 0.02%
Dose↝, safe and effective in various studies where volunteers have taken oral doses ranging from 300 to 625 mg without experiencing any documented effect
neuroP↑, Chrysin has been shown to exert neuroprotective effects via a variety of mechanisms, such as gamma-aminobutyric acid mimetic properties, monoamine oxidase inhibition, antioxidant, anti-inflammatory and anti-apoptotic activities
*P450↓, Chrysin inhibits cytochrome P450 2E1, alcohol dehydrogenase and xanthine oxidase at various dosages (20 and 40 mg/kg body weight) and protects Wistar rats against oxidative stress
*ROS↓,
*HDL↑, ncreased the levels of high-density lipoprotein cholesterol, glutathione S-transferase, superoxide dismutase and catalase
*GSTs↑,
*SOD↑,
*Catalase↑,
*MAPK↓, inactivate the MAPK/JNK pathway and suppress the NF-κB pathways, and at the same time upregulate the expression of PTEN, and activate the VEGF/AKT pathway
*NF-kB↓,
*PTEN↑,

PCNA↓, Chrysin likewise downregulates proliferating cell nuclear antigen (PCNA) expression in cervical carcinoma cells
Twist↓, Chrysin decreases the expression of TWIST 1 and NF-κB and thus suppresses epithelial-mesenchymal transition (EMT) in HeLa cells
EMT↓,
CDKN1C↑, Chrysin administration led to the upregulation of CDKN1 at the transcript and protein leve
p‑STAT3↑, Chrysin decreased the viability of 4T1 breast cancer cells by suppressing hypoxia-induced phosphorylation of STAT3
MMP2↓, chrysin-loaded PGLA/PEG nanoparticles modulated TIMPS and MMP2 and 9, and PI3K expression in a mouse 4T1 breast tumor model
MMP9↓,

CLDN1↓, CLDN1 and CLDN11 expression have been found to be higher in human lung squamous cell carcinoma. Treatment with chrysin treatment reduces both the mRNA and protein expression of these claudin genes
TumVol↓, Treatment with chrysin treatment (1.3 mg/kg body weight) significantly decreases tumor volume, resulting in a 52.6% increase in mouse survival
OS↑,
COX2↓, Chrysin restores the cellular equilibrium of cells subjected to benzopyrene by downregulating the expression of elevated proteins, such as PCNA, NF-κB and COX-2
eff↑, quercetin and chrysin together decreased the levels of pro-inflammatory molecules, such as IL-6, -1 and -10, and the levels of TNF via the NF-κB pathway.

TumCCA↑, halting the cell cycle at the G2/M or G1/S phases
E-cadherin↑, upregulation of E-cadherin and the downregulation of cadherin
