| Licochalcone A - Licorice-Derived Chalcone Type: Natural chalcone / flavonoid-related phytochemical Sources: Found primarily in licorice species including Glycyrrhiza inflata and related Glycyrrhiza plants. Function: Licochalcone A is a bioactive chalcone with anticancer, anti-inflammatory, antioxidant, antimicrobial, and metabolic effects. Reported mechanisms include modulation of PI3K/AKT, MAPK, NF-κB, STAT3, ROS, apoptosis, autophagy, and cell-cycle regulatory pathways. Cancer: Preclinical studies demonstrate inhibition of cancer-cell proliferation, migration, invasion, and metastasis, together with induction of apoptosis, autophagy, oxidative stress, and cell-cycle arrest. LCA has shown anticancer activity in breast, lung, gastric, colorectal, prostate, liver, ovarian, and other experimental cancer models. Alzheimer's Disease: Preclinical evidence suggests neuroprotective and anti-inflammatory effects relevant to neurodegeneration, including suppression of oxidative stress and inflammatory signaling, although the Alzheimer's-specific evidence is less developed than the cancer literature. Licochalcone A — a naturally occurring prenylated chalcone and phenolic phytochemical found principally in licorice species, especially Glycyrrhiza inflata. It is classified as a natural chalcone/flavonoid-related small molecule and is commonly abbreviated LCA, LicA, or Lico A. Its experimental pharmacology is strongly context-dependent: in many cancer models LCA promotes oxidative stress, mitochondrial dysfunction, apoptosis, autophagy, cell-cycle arrest, and suppression of proliferative and inflammatory signaling, whereas in non-malignant injury models it can activate NRF2-dependent antioxidant defenses. Anticancer development remains preclinical. Primary mechanisms (ranked):
Bioavailability / PK relevance: Free oral LCA has poor systemic exposure; a rat pharmacokinetic study reported absolute oral bioavailability of approximately 3.3%. Poor aqueous solubility, limited permeability, intestinal first-pass metabolism, glucuronidation, and other metabolic pathways constrain exposure. Formulation materially changes PK: a self-microemulsifying drug-delivery system increased oral bioavailability approximately 2.36-fold in rats, while nanoparticle approaches have produced still larger increases experimentally. LCA also inhibits P-glycoprotein and several CYP enzymes, particularly CYP3A and CYP2C9 in experimental systems, creating a potential drug-interaction concern. In-vitro vs systemic exposure relevance: Many anticancer experiments use approximately 10–100 μM LCA, with several reported IC50 values in the tens of micromolar range. These concentrations are difficult to reconcile with the low systemic exposure of unformulated oral LCA, so direct translation of conventional cell-culture concentrations to achievable human systemic exposure is uncertain. Delivery systems, local exposure, metabolites, and combination strategies may alter this limitation. Clinical evidence status: Cancer: preclinical only, with cell-culture and animal xenograft evidence but no established anticancer efficacy in humans. Human exposure evidence is substantially stronger for topical dermatologic/cosmetic use: randomized or prospective studies have evaluated LCA-containing formulations for acne, dermatitis, erythema, and rosacea. LCA is not an established systemic oncology drug. Current translational priorities are exposure optimization, human PK, dose-limiting safety characterization, and controlled oncology trials.

P: 0–30 min R: 30 min–3 hr G: >3 hr Alzheimer's disease relevance: Licochalcone A now has meaningful disease-specific preclinical evidence rather than only general neuroprotective plausibility. Studies in transgenic AD mouse models report improved cognition together with reduced Aβ burden, reduced neuroinflammation, improved insulin/glucose signaling, inhibition of ER-stress-mediated neuronal apoptosis, and NRF2-associated protection. A 2026 APP/PS1 study reported improved memory, increased synaptic markers, reduced Aβ42 and plaque burden, improved glucose handling, and reduced glial activation after 15 mg/kg/day intraperitoneal LCA for four weeks. A separate transgenic mouse study found inhibition of PERK/eIF2α/ATF4/CHOP ER-stress signaling and neuronal apoptosis. Evidence remains preclinical; there is no established human AD efficacy. Primary AD mechanisms (ranked):
Clinical evidence status: Preclinical. Evidence includes cell studies and multiple transgenic mouse AD models, including disease-specific studies published in 2025 and 2026. Human efficacy, optimal systemic dose, CNS pharmacokinetics, and long-term safety have not been established. Licochalcone A Alzheimer Mechanisms

| Tumor cell invasion is a critical process in cancer progression and metastasis, where cancer cells spread from the primary tumor to surrounding tissues and distant organs. This process involves several key steps and mechanisms: 1.Epithelial-Mesenchymal Transition (EMT): Many tumors originate from epithelial cells, which are typically organized in layers. During EMT, these cells lose their epithelial characteristics (such as cell-cell adhesion) and gain mesenchymal traits (such as increased motility). This transition is crucial for invasion. 2.Degradation of Extracellular Matrix (ECM): Tumor cells secrete enzymes, such as matrix metalloproteinases (MMPs), that degrade the ECM, allowing cancer cells to invade surrounding tissues. This degradation facilitates the movement of cancer cells through the tissue. 3.Cell Migration: Once the ECM is degraded, cancer cells can migrate. They often use various mechanisms, including amoeboid movement and mesenchymal migration, to move through the tissue. This migration is influenced by various signaling pathways and the tumor microenvironment. 4.Angiogenesis: As tumors grow, they require a blood supply to provide nutrients and oxygen. Tumor cells can stimulate the formation of new blood vessels (angiogenesis) through the release of growth factors like vascular endothelial growth factor (VEGF). This not only supports tumor growth but also provides a route for cancer cells to enter the bloodstream. 5.Invasion into Blood Vessels (Intravasation): Cancer cells can invade nearby blood vessels, allowing them to enter the circulatory system. This step is crucial for metastasis, as it enables cancer cells to travel to distant sites in the body. 6.Survival in Circulation: Once in the bloodstream, cancer cells must survive the immune response and the shear stress of blood flow. They can form clusters with platelets or other cells to evade detection. 7.Extravasation and Colonization: After traveling through the bloodstream, cancer cells can exit the circulation (extravasation) and invade new tissues. They may then establish secondary tumors (metastases) in distant organs. 8.Tumor Microenvironment: The surrounding microenvironment plays a significant role in tumor invasion. Factors such as immune cells, fibroblasts, and signaling molecules can either promote or inhibit invasion and metastasis. |
