Rhamnetin production based on the rational design of the poplar O-methyltransferase enzyme and its biological activities.

Sunhee Lee et al.

Bioorganic & medicinal chemistry letters, 21(13), 3866-3870 (2011-06-10)

To produce rhamnetin using enzymatic engineering, poplar O-methyltransferase-7 and its mutants were prepared based on the rational enzyme design, and the production of rhamnetin was compared with the results obtained using the wild type enzyme. In addition, the potential of

Screening for fractions of Oxytropis falcata Bunge with antibacterial activity.

H Jiang et al.

Natural product research, 23(10), 953-959 (2009-06-13)

Preliminary studies with the four extracts of Oxytropis falcate Bunge exhibited that the chloroform and ethyl acetate extracts showed stronger antibacterial activities against the nine tested Gram-positive and Gram-negative bacteria. The HPLC-scanned and bioassay-guided fractionation led to the isolation and

Regioselective O-derivatization of quercetin via ester intermediates. An improved synthesis of rhamnetin and development of a new mitochondriotropic derivative.

Andrea Mattarei et al.

Molecules (Basel, Switzerland), 15(7), 4722-4736 (2010-07-27)

The regioselective synthesis of several quercetin (3,3',4',5,7-pentahydroxy flavone) tetraesters bearing a single free OH on 5-C was achieved in good yield by proper choice of reaction conditions using common esterification procedures. Tetracetylated quercetin with the free OH on 7-C was
