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.
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)

MMP2, metalloproteinase-2: Click to Expand ⟱
Source:
Type:
Matrix metalloproteinase-2 (MMP-2) is an enzyme that plays a significant role in the degradation of extracellular matrix components, which is crucial for various physiological processes, including tissue remodeling, wound healing, and angiogenesis.
Elevated levels of MMP-2 have been associated with poor prognosis in various cancers, including breast, lung, and colorectal cancers.
MMP2 and MMP9: two enzymes are critical to tumor invasion.
