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?.

AMPK, adenosine monophosphate-activated protein kinase: Click to Expand ⟱
Source:
Type:
AMPK: guardian of metabolism and mitochondrial homeostasis; Upon changes in the ATP-to-AMP ratio, AMPK is activated. (AMPK) is a key metabolic sensor that is pivotal for the maintenance of cellular energy homeostasis. It is well documented that AMPK possesses a suppressor role in the context of tumor development and progression by modulating the inflammatory and metabolic pathways.

-Activating AMPK can inhibit anabolic processes and the PI3K/Akt/mTOR pathway reducing glycolysis shifting toward Oxidative Phosphorlylation.


AMPK activators:
-metformin or AICAR
-Resveratrol: activate AMPK indirectly
-Berberine
-Quercetin: may stimulate AMPK
-EGCG: thought to activate AMPK
-Curcumin: may activate AMPK

-Ginsenosides: Some ginsenosides have been associated with AMPK activation -Beta-Lapachone: A natural naphthoquinone compound found in the bark of Tabebuia avellanedae (also known as lapacho or taheebo). It has been observed to activate AMPK in certain models.
-Alpha-Lipoic Acid (ALA): associated with AMPK activation
