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

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.

Hif1a, HIF1α/HIF1a: Click to Expand ⟱
Source:
Type:
Hypoxia-Inducible-Factor 1A (HIF1A gene, HIF1α, HIF-1α protein product)
-Dominantly expressed under hypoxia(low oxygen levels) in solid tumor cells
-HIF1A induces the expression of vascular endothelial growth factor (VEGF)
-High HIF-1α expression is associated with Poor prognosis
-Low HIF-1α expression is associated with Better prognosis

-Functionally, HIF-1α is reported to regulate glycolysis, whilst HIF-2α regulates genes associated with lipoprotein metabolism.
-Cancer cells produce HIF in response to hypoxia in order to generate more VEGF that promote angiogenesis

Key mediators of aerobic glycolysis regulated by HIF-1α.
-GLUT-1 → regulation of the flux of glucose into cells.
-HK2 → catalysis of the first step of glucose metabolism.
-PKM2 → regulation of rate-limiting step of glycolysis.
-Phosphorylation of PDH complex by PDK → blockage of OXPHOS and promotion of aerobic glycolysis.
-LDH (LDHA): Rapid ATP production, conversion of pyruvate to lactate;

HIF-1α Inhibitors:
-Curcumin: disruption of signaling pathways that stabilize HIF-1α (ie downregulate).
-Resveratrol: downregulate HIF-1α protein accumulation under hypoxic conditions.
-EGCG: modulation of upstream signaling pathways, leading to decreased HIF-1α activity.
-Emodin: reduce HIF-1α expression. (under hypoxia).
-Apigenin: inhibit HIF-1α accumulation.
