Amyloid-β (Aβ) denotes peptides of 36–43 amino acids that are crucially involved in Alzheimer's disease as the main component of theamyloid plaques found in the brains of Alzheimer patients. The peptides result from the amyloid precursor protein (APP), which is being cut by certain enzymes to yield Aβ. Amyloid-β molecules can aggregate to form flexible soluble oligomers which may exist in several forms. Amyloid-β peptide is due to overproduction of Aβ and/or the failure of clearance mechanisms. Amyloid-β self-aggregates into oligomers, which can be of various sizes, and forms diffuse and neuritic plaques in the parenchyma and blood vessels. Amyloid-β oligomers and plaques are potent synaptotoxins, block proteasome function, inhibit mitochondrial activity, alter intracellular Ca2+levels and stimulate inflammatory processes. Loss of the normal physiological functions of Aβ is also thought to contribute to neuronal dysfunction.

Pongamol reduces the release of IL‑1β, TNF‑α, COX‑2 and iNOS in cells, reverses the nuclear translocation of NF‑κB, and upregulates the levels of Beclin 1 and LC3 Ⅱ/LC3 Ⅰ. Pongamol promotes glucose uptake by increasing the level of GLUT4 on the surface of skeletal muscle cells. Pongamol inhibits epithelial-mesenchymal transition by suppressing the FAK/Akt-mTOR signaling pathway. Pongamol inhibits neuronal cytotoxicity, suppresses cell apoptosis and extends the lifespan of Caenorhabditis elegans by activating the MAPKs/Nrf2 signaling pathway. Pongamol exerts hypoglycemic effects in diabetic mouse models. Pongamol exhibits antibacterial activity. Pongamol alleviates oxidative stress, neuroinflammation, Aβ deposition and excessive phosphorylation of Tau Protein, and restores autophagy function in Alzheimer's disease mouse models by inhibiting the Akt/mTOR signaling pathway. Pongamol is applicable to research related to Alzheimer's disease, type 2 diabetes, non-small cell lung cancer and postprandial hyperglycemia.
