Lyco, Lycopene: Click to Expand ⟱
Features:
Lycopene is a naturally occurring carotenoid found predominantly in tomatoes and other red fruits and vegetables.

Antioxidant Properties:
-Lycopene is a powerful antioxidant. It helps neutralize free radicals, which can reduce oxidative stress—a factor implicated in cancer development. Possible concern about interfering with chemotherapy and radiation therapy. However this review disagrees.
Inflammation Reduction:
-Some studies suggest that lycopene may help lower levels of inflammation, another process linked to cancer progression

At supraphysiological or extremely high concentrations, lycopene may have the potential to switch from an antioxidant to a prooxidant role
-The prooxidant effect of lycopene has been observed under conditions of high oxygen tension. In vitro studies have suggested that in environments with elevated oxygen levels, lycopene might promote rather than neutralize the production of reactive oxygen species (ROS).
-The presence of metal ions (such as iron or copper) in the environment can catalyze reactions where antioxidants, including lycopene, contribute to oxidative processes. These metals can interact with lycopene, potentially leading to the formation of radicals.

The mevalonate pathway produces cholesterol and a variety of isoprenoids, which are important for maintaining cell membrane integrity, protein prenylation, and other essential cellular functions.
-One of the primary enzymes in this pathway is HMG-CoA reductase (3-hydroxy-3-methylglutaryl-coenzyme A reductase), which is the target of statin drugs used for lowering cholesterol. Some studies suggest that lycopene might downregulate the activity of HMG-CoA reductase or other enzymes in the mevalonate pathway. By doing so, lycopene could potentially reduce the synthesis of cholesterol and isoprenoids that are necessary for rapid cell proliferation—an especially relevant aspect in cancer cells.

Lycopene typically used in a 100mg/day range for cancer (inhibition of the the Melavonate Pathway)
-also has antiplatelet aggregation capability.

-Note half-life 16–20 days.
BioAv Heat processing, especially when combined with a small amount of fat, significantly enhances lycopene’s bioaccessibility and absorption. (20% under optimal conditions)
Pathways:
- ROS usually goes down, but may go up or down depending on dose and environment. Lycopene may also be modified to be a "oxdiative product" which may change the behaviour.

PI3K, Phosphatidylinositide-3-Kinases: Click to Expand ⟱
Source: HalifaxProj(inhibit) CGL-CS
Type:
Phosphatidylinositol 3-kinase (PtdIns3K or PI3K) is a family of enzymes that play a crucial role in cell signaling pathways, particularly in the regulation of cell growth, survival, and metabolism. The PI3K pathway is one of the most frequently altered pathways in human cancer. Inhibition of the PI3K pathway has been explored as a therapeutic strategy for cancer treatment. Several PI3K inhibitors have been developed and are currently being tested in clinical trials. These inhibitors can target specific components of the pathway, such as PI3K, AKT, or mTOR.

Class I phosphoinositide 3-kinase (PI3K)
Class III PtdIns3K
In contrast to the class III PtdIns3K as a positive regulator of autophagy, class I PI3K-AKT signaling has an opposing effect on the initiation of autophagy.

PI3K inhibitors include:
-Idelalisib , Copanlisib, Alpelisib
-LY294002?
-Wortmannin: potent PI3K inhibitor, has some associated toxicity.
-Quercetin:
-Curcumin
-Resveratrol
-Epigallocatechin Gallate (EGCG)
