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?.
BioAv low, poor water solubility

3051- SK,    Resveratrol mediates its anti-cancer effects by Nrf2 signaling pathway activation
- Review, Var, NA
Nrf1↑, Resveratrol is a natural compound that can activate the Nrf2 transcription factor
Apoptosis↑, In different cell lines, resveratrol can increase apoptosis and inhibit the proliferation of cancer cells.
TumCP↓,
eff⇅, But there is a controversy on whether activation of Nrf2 is of clinical benefit in cancer therapy or is a carcinogen?
chemoP↑, chemoprevention effects
eff↑, It has also been suggested that reduction in oxidative conditions in cancer cells may enhance the anticancer effects of antineoplastic drugs [4].
VCAM-1↓, Resveratrol was effective on angiogenesis through an inhibitory direct effect on vascular endothelial growth factor (VEGF) generation and also inhibiting the hypoxia-inducible factor (HIF)-1generation and leads to preventing VEGF secretion

2189- SK,    PKM2 inhibitor shikonin suppresses TPA-induced mitochondrial malfunction and proliferation of skin epidermal JB6 cells
- in-vitro, Melanoma, NA
PKM2↓, shikonin suppressed the tumor promoter 12-O-tetradecanoylphorbol 13-acetate (TPA) induced neoplastic cell transformation and PKM2 activation in the early stage of carcinogenesis.
chemoP↑, results suggest that shikonin bears chemopreventive potential for human skin cancers in which PKM2 is upregulated,
eff↝, PKM2 activity was increased by 2.5-fold in tumor samples than normal tissues
lactateProd↓, Shikonin Suppressed TPA-Induced Lactate Production
ROS↑, shikonin induces apoptosis in hepatocellular carcinoma cells by the reactive oxygen species (ROS)/Akt and RIP1/NF-κB pathways
*ROS?, in our study, shikonin could preserve mitochondrial function and decrease the levels of ROS, leading to blocking PKM2 activation.
*PKM2↓,


* indicates research on normal cells as opposed to diseased cells
