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:

Notch signaling pathway is a regulator of self-renewal and differentiation in several tissues and cell types.; Notch hyperactivation has been implicated as oncogenic in several cancers including breast cancer and T-cell acute lymphoblastic leukemia (T-ALL).
Due to its dual roles, NOTCH signaling is being explored as a therapeutic target. Inhibitors of NOTCH signaling are being investigated in clinical trials for various cancers, particularly those with aberrant NOTCH activation.
The abnormal activation of the NOTCH pathway has been linked to increased cancer cell growth, survival, invasion, and resistance to chemotherapy and radiation therapy. On the other hand, blocking the NOTCH pathway has been shown to trigger cancer cell differentiation and cell death, and it makes them more responsive to therapy. Hence, inhibiting the NOTCH pathway has become a promising approach for treating cancer, and various NOTCH pathway inhibitors are currently under development for cancer treatment.
