HNK, Honokiol: Click to Expand ⟱
Features:
Honokiol is a Lignan isolated from bark, seed cones and leaves of trees of Magnolia species. Honokiol was traditionally used for anxiety and stroke treatment, as well as the alleviation of flu symptoms.
-considered to have antioxidant properties
-low oral bioavailability and difficulty in intravenous administration
-the development of various formulations of honokiol, including microemulsion, liposomes, nanoparticles and micelle copolymers have successfully solved the problem of low water solubility.

Pathways:
-Inhibit NF-κB activation
-Downregulate STAT3 signalin
-Inhibiting the PI3K/Akt pathway,
-Inhibition of mTOR
-Influences various MAPK cascades—including ERK, JNK, and p38
-Inhibition of EGFR
-Inhibiting Notch pathway (CSCs)
-GPx4 inhibit
-Can induce ER stress in cancer cells, which contributes to the activation of unfolded protein response (UPR) pathways
-Disrupt the mitochondrial membrane potential in cancer cells.
-Reported to increase ROS production in cancer cells
-Can exhibit antioxidant properties in normal cells. - has some inhibitor activity but Not classified as HDAC inhibitor as weaker and may work more indirectly.
- is well-known in the research community for its role in activating SIRT3

-Note half-life 40–60 minutes

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 Mitochondrial integrity / intrinsic apoptosis ↓ ΔΨm; ↑ cytochrome-c release; ↑ caspases ↔ largely preserved Driver Mitochondria-directed cytotoxicity Honokiol directly accumulates in mitochondria and initiates intrinsic apoptosis in cancer cells
2 Reactive oxygen species (ROS) ↑ ROS (secondary, stress-amplifying) ↔ buffered Secondary Mitochondrial stress amplification ROS elevation follows mitochondrial perturbation rather than acting as the initiating trigger
3 STAT3 signaling ↓ STAT3 activation ↔ minimal Driver Loss of survival and stemness signaling STAT3 suppression contributes to apoptosis, CSC targeting, and reduced proliferation
4 PI3K → AKT → mTOR axis ↓ AKT / ↓ mTOR ↔ adaptive suppression Secondary Growth and anabolic inhibition AKT/mTOR inhibition reinforces mitochondrial and apoptotic stress
5 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Secondary Suppression of survival transcription NF-κB inhibition contributes to chemosensitization and anti-inflammatory effects
6 Cell cycle regulation ↑ G0/G1 or G2/M arrest ↔ spared Phenotypic Cytostatic growth control Cell-cycle arrest reflects upstream signaling disruption
7 Autophagy ↑ autophagy (context-dependent) ↑ adaptive autophagy Adaptive Stress response vs death cooperation Autophagy may precede apoptosis or act as a transient survival response


IFN-γ, Interferon-γ: Click to Expand ⟱
Source:
Type:
Plays a key role in activation of cellular immunity and subsequently, stimulation of antitumor immune-response. Based on its cytostatic, pro-apoptotic and antiproliferative functions, IFN-γ is considered potentially useful for adjuvant immunotherapy for different types of cancer.
Moreover, it IFN-γ may inhibit angiogenesis in tumor tissue, induce regulatory T-cell apoptosis, and/or stimulate the activity of M1 proinflammatory macrophages to overcome tumor progression.
However, the current understanding of the roles of IFN-γ in the tumor microenvironment (TME) may be misleading in terms of its clinical application.

IFN-γ is often expressed in the tumor microenvironment, particularly in response to immune cell infiltration. Its expression can be influenced by the presence of tumor-infiltrating lymphocytes (TILs) and other immune cells.
High levels of IFN-γ are typically associated with a Th1 immune response, which is generally considered beneficial for anti-tumor immunity.

Tumor Suppression:
In many cases, IFN-γ has tumor-suppressive effects, as it can inhibit tumor cell proliferation and induce apoptosis in certain cancer types.
