SK, Shikonin: Click to Expand ⟱
Features:
The (R)-enantiomer of alkannin is known as shikonin, and the racemic mixture of the two is known as shikalkin.
Shikonin is a naphthoquinone derivative primarily isolated from the roots of plants in the Boraginaceae family (e.g., Lithospermum erythrorhizon).
Shikonin is the main active component of a Chinese medicinal plant 'Zi Cao'
-Shikonin is a major component of zicao (purple gromwell, the dried root of Lithospermum erythrorhizon), a Chinese herbal medicine with anti-inflammatory properties
-Quinone methides (QMs) are highly reactive intermediates formed from natural compounds like shikonin
-ic50 cancer cells 1-10uM, normal cells >10uM

-known as Glycolysis inhibitor: ( inhibit pyruvate kinase M2 (PKM2*******), a key enzyme in the glycolytic pathway)

Available from mcsformulas.com Shikonin Pro Liposomal, 30 mg
Also In Glycolysis Inhibithree(100 mg PHLORIZIN,10 mg TANSHINONE IIA, 8 mg Shikonin)

-Note half-life15-30mins or 8hr?.

VEGF, Vascular endothelial growth factor: Click to Expand ⟱
Source: HalifaxProj (inhibit)
Type:
A signal protein produced by many cells that stimulates the formation of blood vessels. Vascular endothelial growth factor (VEGF) is a signal protein that plays a crucial role in angiogenesis, the process by which new blood vessels form from existing ones. This process is vital for normal physiological functions, such as wound healing and the menstrual cycle, but it is also a key factor in the growth and spread of tumors in cancer.
Because of its significant role in tumor growth and progression, VEGF has become a target for cancer therapies. Anti-VEGF therapies, such as monoclonal antibodies (e.g., bevacizumab) and small molecule inhibitors, aim to inhibit the action of VEGF, thereby reducing blood supply to tumors and limiting their growth. These therapies have been used in various types of cancer, including colorectal, lung, and breast cancer.

ROS↑, their induction of reactive oxygen species production, inhibition of EGFR and PI3K/AKT signaling pathway activation, inhibition of angiogenesis and induction of apoptosis and necroptosis
EGFR↓,
PI3K↓,
Akt↓,
angioG↓,
Apoptosis↑,
Necroptosis↑,
GSH↓, leading to the increased consumption of reduced glutathione (GSH) and increased Ca2+ concentration in the cells and destroying the mitochondrial membrane potential.
Ca+2↓,
MMP↓,
ERK↓, 24 h of treatment with shikonin, ERK 1/2 and AKT activities were significantly inhibited, and p38 activity was upregulated, which ultimately led to pro-caspase-3 cleavage and triggered the apoptosis of GC cells.
p38↑,
proCasp3↑,
eff↓, pretreated with the ROS scavengers NAC and GSH before treatment with shikonin, the production of ROS was significantly inhibited, the cytotoxicity of shikonin was attenuated
VEGF↓, shikonin can inhibit the expression of VEGF
FOXO3↑, Activated FOXO3a/EGR1/SIRT1 signaling
EGR1↑,

BioAv↓, limitations caused by its poor water solubility, it has a short half-life and nonselective biological distribution
NF-kB↓, Shikonin can also prevent the activation of NF-κB by AKT and then downregulate the expression of Bcl-xl,
Half-Life↓, due to the limitations caused by its poor water solubility, it has a short half-life and nonselective biological distribution.
