| Andrographis — Andrographis (typically Andrographis paniculata, “King of Bitters”) is a bitter medicinal plant whose principal bioactive diterpenoid lactone is andrographolide (with related diterpenoids such as neoandrographolide). It is best classified as a botanical drug / phytochemical mixture (plant extract) with a dominant small-molecule active. Common abbreviation(s): AP (plant), AND (andrographolide). The best-supported pharmacology in humans is anti-inflammatory/immunomodulatory use (e.g., URTI symptom reduction), while oncology relevance is predominantly preclinical, with frequent reporting of NF-κB/STAT3/PI3K-AKT pathway suppression and downstream effects on proliferation, apoptosis, invasion, and angiogenesis. Primary mechanisms (ranked):
Bioavailability / PK relevance: Oral exposure of andrographolide from extracts is highly formulation-dependent and often low; even at high oral regimens used clinically (e.g., extract equivalents targeting ~180–360 mg/day andrographolide), measured plasma concentrations can remain in the low ng/mL range and may show non-linear dose proportionality. This creates a translation gap for many oncology in-vitro concentrations unless delivery is optimized (e.g., solubility enhancement, lipid/polymer carriers, prodrugs). In-vitro vs systemic exposure relevance: Many reported anticancer effects occur at micromolar in-vitro levels that commonly exceed achievable free systemic concentrations after standard oral supplementation; therefore, “direct cytotoxic” interpretations are frequently exposure-limited, while anti-inflammatory signaling modulation may be more plausibly aligned with in-vivo exposures depending on tissue distribution and formulation. Clinical evidence status: Human clinical evidence is strongest for infectious/inflammatory indications (URTI symptom reduction; studied in COVID-19-era settings with mixed outcomes and safety monitoring). For oncology, evidence is primarily preclinical, with limited registered/early clinical exploration and no established standard anticancer indication. "used traditionally for the treatment of array of diseases such as cancer, diabetes, high blood pressure, ulcer, leprosy, bronchitis, skin diseases, flatulence, colic, influenza, dysentery, dyspepsia and malaria for centuries in Asia, America and Africa continents." Andrographolide: – Is a specific diterpenoid lactone and the major active constituent extracted from Andrographis paniculata. – It is responsible for many of the therapeutic effects attributed to the plant, including anti-inflammatory and antioxidant properties. A. Anti-Inflammatory Effects. • Andrographolide has been shown to inhibit the NF-κB pathway, leading to a reduction in the transcription of inflammatory cytokines (e.g., TNF-α, IL-6). • Andrographolide has been reported to cause cell cycle arrest at critical checkpoints (such as G0/G1 or G2/M phase) in some cancer cell models. Andrographis, primarily through its active constituent andrographolide, offers compelling anti-inflammatory, immunomodulatory, pro-apoptotic, and antiproliferative properties. While not a standard anticancer agent, its capacity to modulate key pathways in cellular stress response and inflammation makes it an attractive candidate for complementary research in oncology. Andrographis paniculata, also known as the "King of Bitters," is a plant native to India and Southeast Asia. Its aqueous extract, Andrographis paniculata aqueous extract (APAE), has been studied for its potential anti-cancer properties. • Inhibition of cancer cell growth: APAE has been shown to inhibit the growth of various cancer cell lines, including breast, lung, colon, and prostate cancer cells. • Induction of apoptosis: APAE has been found to induce apoptosis (programmed cell death) in cancer cells, which may help to prevent tumor growth and progression. • Anti-inflammatory effects: APAE has anti-inflammatory properties, which may help to reduce the risk of cancer development and progression. • Antioxidant activity: APAE has antioxidant activity, which may help to protect against oxidative stress and DNA damage. Key compounds:Andrographolide, Neoandrographolide APAE may interact with certain medications, including blood thinners and diabetes medications, and may not be suitable for individuals with certain medical conditions, such as autoimmune disorders.

| Nrf2 is responsible for regulating an extensive panel of antioxidant enzymes involved in the detoxification and elimination of oxidative stress. Thought of as "Master Regulator" of antioxidant response. -One way to estimate Nrf2 induction is through the expression of NQO1. NQO1, the most potent inducer: SFN 0.2 μM, quercetin (2.5 μM), curcumin (2.7 μM), Silymarin (3.6 μM), tamoxifen (5.9 μM), genistein (6.2 μM ), beta-carotene (7.2μM), lutein (17 μM), resveratrol (21 μM), indol-3-carbinol (50 μM), chlorophyll (250 μM), alpha-cryptoxanthin (1.8 mM), and zeaxanthin (2.2 mM) 1. Raising Nrf2 enhances the cell's antioxidant defenses and ↓ROS. This strategy is used to decrease chemo-radio side effects. 2. Downregulating Nrf2 lowers antioxidant defenses and ↑ROS. In cancer cells this leads to DNA damage, and cell death. 3. However there are some cases where increasing Nrf2 paradoxically causes an increase in ROS (cancer cells). Such as cases of Mitochondial overload, signal crosstalk, reductive stress -In some cases, Nrf2 is overexpressed in cancer cells, which can lead to the activation of genes involved in cell proliferation, angiogenesis, and metastasis. This can contribute to the development of resistance to chemotherapy and targeted therapies. -Increased Nrf2 expression: Lung, Breast, Colorectal, Prostrate. Decreased Nrf2 expression: Skine, Liver, Pancreatic. -Nrf2 is a cytoprotective transcription factor which demonstrated both a negative effect as well as a positive effect on cancer - "promotes Nrf2 translocation from the cytoplasm to the nucleus," means facilitates the movement of Nrf2 into the nucleus, thereby enhancing the cell's antioxidant and cytoprotective responses. -Major regulator of Nrf2 activity in cells is the cytosolic inhibitor Keap1. Nrf2 Inhibitors and Activators Nrf2 Inhibitors: Brusatol, Luteolin, Trigonelline, VitC, Retinoic acid, Chrysin Nrf2 Activators: SFN, OPZ EGCG, Resveratrol, DATS, CUR, CDDO, Api - potent Nrf2 inducers from plants include sulforaphane, curcumin, EGCG, resveratrol, caffeic acid phenethyl ester, wasabi, cafestol and kahweol (coffee), cinnamon, ginger, garlic, lycopene, rosemany Nrf2 plays dual roles in that it can protect normal tissues against oxidative damage and can act as an oncogenic protein in tumor tissue. – In healthy tissues, NRF2 activation helps protect cells from oxidative damage and maintains cellular homeostasis. – In many cancers, constitutive activation of NRF2 (often through mutations in NRF2 itself or loss-of-function mutations in KEAP1) leads to an enhanced antioxidant capacity. – This upregulation can promote tumor cell survival by enabling cancer cells to thrive under oxidative stress, resist chemotherapeutic agents, and sustain metabolic reprogramming. – Elevated NRF2 levels have been implicated in promoting tumor growth, metastasis, and resistance to therapy in various malignancies. – High or sustained NRF2 activity is frequently associated with aggressive tumor phenotypes, poorer prognosis, and decreased overall survival in several cancer types. – While its activation is essential for protecting normal cells from oxidative stress, aberrant or sustained NRF2 activation in tumor cells can lead to enhanced survival, therapeutic resistance, and tumor progression. NRF2 inhibitors: (to decrease antioxidant defenses and increase cell death from ROS). -Brusatol: most cited natural inhibitors of Nrf2. -Luteolin: luteolin can reduce Nrf2 activity in specific cancer models and may enhance cell sensitivity to chemotherapy. However, luteolin is also known as an antioxidant, and its influence on Nrf2 can sometimes be context dependent. -Apigenin: certain studies to down‑regulate Nrf2 in cancer cells: Dose and context dependent . -Oridonin: -Wogonin: although its effects might be cell‑ and dose‑specific. - Withaferin A |
