Pongamol
Based on 1 Customer Validation
Pongamol (Lanceolatin C) is an orally active flavonoid with an IC50 of 75 μM and a Ki of 58 μM against PTPase-1B, and an IC50 of 103.5 μM against intestinal α-Glycosidase. 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.

Actividad biológica
Pongamol (25-100 μM, pre-incubated for 1 h followed by LPS stimulation for 24 h) inhibits LPS (HY-D1056)-induced NO release in BV2 mouse microglia. It suppresses LPS-induced activation of the NF-κB pathway in cells by reducing IκB phosphorylation and blocking NF-κB nuclear translocation, and downregulates the expression of pro-inflammatory genes (IL-1β, TNF-α, iNOS, COX-2) in cells[1].
Pongamol (100 μM, pretreated for 1 h followed by LPS stimulation for 24 h) reduces the levels of proinflammatory proteins (IL-6, IL-1β) and upregulates the expression of autophagy markers (Beclin 1, LC3 II/LC3 I) in LPS-stimulated mouse BV2 microglial cells, and these effects depend on the Akt pathway[1].
Pongamol (0-10 μM; 0-16 h) increases both basal and insulin-superimposed glucose uptake in L6-GLUT4myc myotubes, elevates both basal and insulin-enhanced GLUT4 translocation to the cell surface by activating PI3-kinase activity, and potentiates Insulin (HY-P0035)-induced AKT (Ser-473) phosphorylation in myotubes[2].
Pongamol (0-100 μM, 2 h) increases the survival rate of H2O2-induced PC12 cells, reduces LDH release, inhibits cell apoptosis, restores mitochondrial membrane potential, decreases the levels of pro-apoptotic proteins and increases the levels of anti-apoptotic proteins, suppresses the activation of the MAPKs signaling pathway (reduces the levels of p-ERK, p-JNK and p-p38), elevates GSH levels and reduces ROS levels, promotes Nrf2 nuclear translocation, upregulates the expression of downstream antioxidant genes and directly binds to Keap1, thereby activating the Nrf2/HO-1 signaling pathway[3].
Pongamol (0-100 μM; 24-48 h) reduces the viability of H460 non-small cell lung cancer cells in a dose-dependent manner, and inhibits cell proliferation, anchorage-independent growth, migration and invasion[4].
Pongamol (25-100 μM; 24 h) upregulates the epithelial marker E-cadherin, downregulates the mesenchymal markers N-cadherin, vimentin, Slug and Snail, inhibits the activation of the FAK/Akt-mTOR signaling pathway, and reduces the levels of phosphorylated FAK, Akt and mTOR in H460 non-small cell lung cancer cells[4].
Pongamol (Compound 1) potently inhibits recombinant protein tyrosine phosphatase-1B (PTPase-1B) in cell-free assays, with an IC50 of 75 μM and a Ki of 58 μM[5].
Pongamol (Compound 6) potently inhibits rat intestinal α-glucosidase with an IC50 of 103.5 μM[6].
Pongamol is active against E. coli and S. aureus (MICs = 8 and 6 µg/mL, respectively)[7].
