Xanthones from Cudrania tricuspidata displaying potent α-glucosidase inhibition
, 2007 We have proven that xanthones 1-8 isolated from the root of C. tricuspidata possess highly potent αα-glucosidase inhibition properties. Compound 1 was identified as a new isoprenylated tetrahydroxy xanthone, 1,3,6,7-tetrahydroxy-2-(3-methylbut-2-enyl)-8-(

Effect of Xanthone and 1-Hydroxy Xanthone on the Dipole Potential of Lipid Membranes
Colloid and Interface Science Communications, 2018 Abstract Xanthone (Xa) and 1-OH Xanthone (1-OHXa) in 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) membranes increase the dipole potential. Results with 1,2-di-O-tetradecyl-sn-glycero-3-phosphocholine (Ether PC), lacking carbonyl groups, indicate that the CO dipole of Xa molecule does not contribute to the increase of dipole potential. Molecular

, 2020 Xanthones are a class of heterocyclic natural products that have been widely studied for their pharmacological potential. In fact, they have been serving as scaffolds for the design of derivatives focusing on drug development. One of the main study targets of xanthones is their anticancer activity. Several compounds belonging to this class have already
