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

MMP9, MMP9: Click to Expand ⟱
Source: HalifaxProj(suppress)
Type:
Matrix metalloproteinase-9 (MMP-9) is an enzyme that plays a significant role in the degradation of extracellular matrix components.
MMP-9 facilitates the breakdown of the extracellular matrix, which can enable cancer cells to invade surrounding tissues and spread to distant sites (metastasis).
Elevated levels of MMP-9 have been associated with poor prognosis in several cancers, including breast, lung, and colorectal cancers.
MMP2 and MMP9: two enzymes are critical to tumor invasion.
