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

- Selectivity: Cancer Cells vs Normal Cells

Rank	Pathway / Target Axis	Direction	Primary Effect	Notes / Cancer Relevance
1	PKM2-mediated aerobic glycolysis (Warburg metabolism)	↓	Energy / biomass restriction	Key, repeatedly reported mechanism: shikonin suppresses PKM2 activity and PKM2-driven glycolysis in multiple tumor models, with downstream growth inhibition and apoptosis
2	ROS accumulation / oxidative stress	↑ ROS	Redox overload	Common upstream trigger that drives mitochondrial dysfunction and regulated cell death programs; often precedes necroptosis/apoptosis signaling
3	Necroptosis core cascade (RIPK1 → RIPK3 → MLKL)	↑	Programmed necrotic cell death	Strong evidence across cancers (e.g., leukemia and nasopharyngeal carcinoma): shikonin increases RIPK1/RIPK3/MLKL expression/activation; necroptosis inhibitors can blunt the effect
4	Mitochondrial integrity (ΔΨm)	↓	Mitochondrial dysfunction	ROS-linked depolarization; acts as a pivot into intrinsic apoptosis and other death programs
5	Intrinsic apoptosis (BAX/BAK → Caspase-9/3)	↑	Programmed cell death	Frequently observed; often framed as ROS → mitochondrial damage → caspase-dependent apoptosis
6	PKM2/STAT3 signaling axis	↓	Reduced survival & proliferation signaling	In ESCC and related models, shikonin suppresses PKM2-driven glycolysis and down-modulates STAT3 pathway activity
7	NF-κB pathway	↓	Reduced pro-survival transcription	Reported as part of multi-target suppression of inflammatory/anti-apoptotic programs in several tumor models and reviews
8	PI3K–AKT (± mTOR)	↓	Growth & resistance pathway inhibition	Often described as sensitizing cells to apoptosis/TRAIL; may be secondary to oxidative stress and metabolic collapse
9	Stress MAPKs (JNK / p38)	↑	Pro-death stress signaling	Common downstream response to ROS; can reinforce apoptosis and other death outcomes
10	Ferroptosis-related axis (lipid peroxidation; GPX4)	↑ lipid perox / ↓ GPX4	Iron-dependent oxidative death	Reported prominently for acetylshikonin (a shikonin derivative): ROS-associated lipid peroxidation with reduced GPX4 expression alongside RIPK1/RIPK3/MLKL activation
11	Endoplasmic reticulum stress (UPR / ERS)	↑	Proteotoxic stress signaling	Frequently mentioned in leukemia-focused mechanism summaries and broader reviews as contributory to growth arrest and death
12	Multiple regulated death programs (apoptosis / necroptosis / ferroptosis / pyroptosis)	↑ (context-dependent)	Broader cell-death engagement	Recent reviews emphasize that shikonin can engage several programmed cell death modalities depending on cell context and dosing

Rank	Pathway / Target Axis	Direction	Primary Effect	Notes / Cancer Relevance	Ref

2	PKM2 → STAT3 signaling axis	↓ PKM2-driven signaling / ↓ STAT3 pathway	Reduced survival & proliferation	ESCC study: shikonin suppresses PKM2-mediated aerobic glycolysis and regulates PKM2/STAT3 signaling	(ref)
3	Necroptosis (RIPK1 → RIPK3 → MLKL)	↑ RIPK1/RIPK3/MLKL	Programmed necrotic cell death	Nasopharyngeal carcinoma: shikonin induces necroptosis with upregulation of RIPK1/RIPK3/MLKL (with ROS involvement)	(ref)
4	ROS accumulation	↑ ROS	Oxidative stress trigger	Colon cancer model: shikonin increases intracellular ROS; ROS functions upstream of apoptosis	(ref)

6	ER stress / UPR (PERK → eIF2α → CHOP)	↑	Proteotoxic stress apoptosis signaling	Colon cancer: shikonin-induced apoptosis mediated by PERK/eIF2α/CHOP ER-stress pathway	(ref)
7	Autophagic flux (autophagosome–lysosome completion)	↓ autophagic flux (blocked)	ROS + apoptosis amplification	Colorectal cancer: shikonin induces ROS and apoptosis by inhibiting autophagic flux	(ref)
8	NF-κB signaling	↓ NF-κB activity	Reduced pro-survival transcription	Pancreatic cancer xenograft/mechanistic study: shikonin suppresses NF-κB activity and NF-κB–regulated gene products	(ref)
9	PI3K–AKT–mTOR (stemness / chemoresistance axis)	↓ PI3K/AKT/mTOR	Reduced survival & stemness	Chemoresistant lung cancer CSC context: shikonin attenuates PI3K–Akt–mTOR pathway and reduces cancer stemness	(ref)
10	Cell cycle control (p21; G2/M arrest)	↑ p21 / ↑ G2/M arrest	Proliferation block	Gastric cancer (AGS): shikonin induces cell-cycle arrest linked to p21 regulation	(ref)
11	Invasion / metastasis programs (NF-κB-linked)	↓ invasion	Anti-invasive phenotype	Reports shikonin inhibits tumor invasion via down-regulation of NF-κB–related mechanisms in a high-metastatic tumor model	(ref)
12	Chemosensitization via glycolysis suppression	↓ glycolysis / ↑ cisplatin sensitivity	Combination benefit	NSCLC: shikonin inhibits glycolysis and sensitizes cells to cisplatin (explicitly connecting metabolic suppression to chemosensitization)	(ref)

Type:

NF-kB signaling
Nuclear factor kappa B (NF-κB) is a transcription factor that plays a crucial role in regulating immune response, inflammation, cell proliferation, and survival.
NF-κB is often found to be constitutively active in many types of cancer cells. This persistent activation can promote tumorigenesis by enhancing cell survival, proliferation, and metastasis.
