Features: Compound
Brazilian Green Propolis often considered best
• Derived from Baccharis dracunulifolia, this type is rich in artepillin C.
• It has been widely researched for its anticancer, anti-inflammatory, and antioxidant properties.
-Propolis common researched flavonoids :chrysin, pinocembrin, galangin, pinobanksin(Pinocembrin)
-most representative phenolic acids were caffeic acid, p-coumaric acid, and ferulic acid, as well as their derivatives, DMCA and caffeic acid prenyl, benzyl, phenylethyl (CAPE), and cinnamyl esters
-One of the most studied active compounds of a poplar-type propolis is caffeic acid phenethyl ester (CAPE)
-caffeic acid phenethyl ester (CAPE), galangin, chrysin, nemorosone, propolin G, artepillin C, cardanol, pinocembrin, pinobanksin, chicoric acid, and phenolic acids (caffeic acid, ferulic acid, and coumaric acid), as well as luteolin, apigenin, myricetin, naringenin, kaempferol, quercetin, polysaccharides, tannins, terpenes, sterols, and aldehydes -content highly variable based on location and extraction
Two main factors of interest:
1. affects interstitual fluild pH
2. high concentration raises ROS (Reactive Oxygen Species), while low concentration may reduce ROS

- Artepillin-C (major phenolic compounds found in Brazilian green propolis (BGP))
- caffeic acid major source

Propolis is chemically diverse (300+ compounds reported) and composition depends on botanical/geographic source.
Antibacterial activity is documented in classic literature (often stronger against Gram+).
CAPE from propolis has reported preferential tumor cytotoxicity in early landmark work (often cited in antimicrobial paper references)

Do not combine with 2DG

Pathways:
-Propolis compounds (e.g., artepillin C, caffeic acid phenethyl ester [CAPE]) can trigger apoptosis (programmed cell death) in cancer cells.
-Propolis has been shown to inhibit NF‑κB activation.
-Propolis extracts can cause cell cycle arrest at specific checkpoints (e.g., G0/G1 or G2/M phases).
-Enhance the body’s antitumor immune responses, for example by activating natural killer (NK) cells and modulating cytokine profiles.

-Note half-life no standard, high variablity of content.
BioAv poor water solubility, and low oral bioavailability.
Pathways:
- high concentration may induce ROS production, while low concentrations mya low it. This may apply to both normal and cancer cells. Normal Cells Example. (Also not sure if high level are acheivable in vivo due to bioavailability)

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Axis Cancer Cells Normal Cells TSF Primary Effect Notes / Interpretation
1 ROS / redox stress (context-selective) Often ↑ ROS / oxidative stress susceptibility (P→R→G) Often antioxidant / cytoprotective in inflammatory stress contexts (R→G) P, R, G Stress amplifier / selectivity gate Net ROS direction is highly context- and extract-dependent; propolis chemistry varies by geography/plant source and can shift redox behavior.
2 NF-κB inflammatory transcription ↓ NF-κB activity (R→G) Anti-inflammatory signaling in immune/tissue contexts (R→G) R, G Anti-inflammatory / anti-survival transcription A common “hub” claim across propolis literature; contributes to reduced cytokine/pro-survival programs.
3 Intrinsic apoptosis (mitochondria → caspases) ↑ apoptosis; ↑ caspase activation (G) ↔ (usually less activation) G Cell death execution Often downstream of sustained stress signaling and/or survival pathway suppression.
4 MAPK re-wiring (ERK / p38 / JNK) Stress MAPK shifts; JNK/p38 often ↑ with stress (P→R); ERK variable ↔ / context-dependent P, R, G Signal reprogramming MAPK directions depend on extract composition, dose, and tumor type; best described as “re-wiring” rather than fixed arrows for ERK.
5 PI3K → AKT (± mTOR) ↓ PI3K/AKT survival signaling (R→G) R, G Growth/survival suppression Often reported alongside reduced proliferation and increased apoptosis susceptibility.
6 Nrf2 / antioxidant response (HO-1, GSH enzymes) Context-dependent (may be ↓ in tumor-stress settings; may be ↑ as adaptation) Often ↑ protective antioxidant response under stress R, G Adaptive buffering Nrf2 direction is not universal; avoid absolute “Nrf2 always ↑/↓” statements for propolis.
7 Angiogenesis (VEGF and related factors) ↓ angiogenic signaling outputs (G) G Anti-angiogenic support Usually shows up in later gene-expression / phenotype assays rather than early signaling.
8 EMT / invasion / migration (MMPs, EMT markers) ↓ EMT / ↓ migration & invasion programs (G) G Anti-invasive phenotype Often measured as reduced MMP activity and reduced migration/invasion phenotypes; timing tends to be later.
9 Antimicrobial / microbiome-relevant effects Indirect (may reduce infection-driven inflammation) Direct antimicrobial activity (context) R, G Host-protective / anti-infective Propolis has documented antibacterial activity (stronger vs many Gram+ than Gram− in classic reports), which can matter for inflammation-linked biology.
10 Key bioactives (CAPE; flavonoids/phenolics) CAPE-class compounds: tumor-selective cytotoxicity reported (G) G “Active fraction” concept Propolis is a mixture; effects may be driven by a few high-impact phenolics (e.g., CAPE) and vary by extract standardization.

Time-Scale Flag (TSF): P / R / G

  • P: 0–30 min (primary/physical–chemical effects; rapid signaling / phosphorylation shifts)
  • R: 30 min–3 hr (redox signaling + acute stress-response signaling)
  • G: >3 hr (gene-regulatory adaptation and phenotype-level outcomes)


CDK6, Cyclin-dependent kinase 6: Click to Expand ⟱
Source:
Type:
Cyclin-dependent kinase 6 (CDK6) is another important regulator of the cell cycle, particularly involved in the transition from the G1 phase to the S phase.
CDK6 is frequently overexpressed in various cancers, and its expression levels can serve as a prognostic marker. Targeting CDK6 with specific inhibitors, such as palbociclib (which also targets CDK4), has shown promise in clinical settings, particularly in hormone receptor-positive breast cancer.
