| 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

| Phosphatidylinositol 3-kinase (PtdIns3K or PI3K) is a family of enzymes that play a crucial role in cell signaling pathways, particularly in the regulation of cell growth, survival, and metabolism. The PI3K pathway is one of the most frequently altered pathways in human cancer.
Inhibition of the PI3K pathway has been explored as a therapeutic strategy for cancer treatment. Several PI3K inhibitors have been developed and are currently being tested in clinical trials. These inhibitors can target specific components of the pathway, such as PI3K, AKT, or mTOR. Class I phosphoinositide 3-kinase (PI3K) Class III PtdIns3K In contrast to the class III PtdIns3K as a positive regulator of autophagy, class I PI3K-AKT signaling has an opposing effect on the initiation of autophagy. PI3K inhibitors include: -Idelalisib , Copanlisib, Alpelisib -LY294002? -Wortmannin: potent PI3K inhibitor, has some associated toxicity. -Quercetin: -Curcumin -Resveratrol -Epigallocatechin Gallate (EGCG) |
