Herein, a new substrate-controlled hydrogenation of flavanones to selectively obtain 2′-hydroxy-1,3-diarylpropanes or flavans depending on the substitution of the flavanone moiety is described. Thus, hydrogenation of non-fluorinated flavanones provided the corresponding 2′-hydroxy-1,3-diarylpropanes, whereas hydrogenation of fluorinated flavanones afforded selectively the corresponding flavans in excellent

Nucleoside transporter inhibitors have potential therapeutic applications as anticancer, antiviral, cardio-protective and neuroprotective agents. Although quite a few potent inhibitors of the equilibrative nucleoside transporters are known, largely missing are the concentrative nucleoside transporter inhibitors. Phloridzin (3, K-i = 16.00 mu M) is a known moderate inhibitor of the concentrative nucleoside transporters. We have synthesized and evaluated analogs of phloridzin at the hCNT3 nucleoside transporter. Within the series of synthesized analogs compound 16 (K-i = 2.88 mu M), possessing a ribofuranose sugar unit instead of a glucopyranose as present in phloridzin, exhibited the highest binding affinity at the hCNT3 transporter. Phloridzin and compound 16 have also been shown to be selective for the hCNT3 transporter as compared with the hENT1 transporter. Compound 16 can serve as a new lead which after further modi. cations could yield selective and potent hCNT3 inhibitors. (C) 2008 Elsevier Ltd. All rights reserved.

A beverage or other composition may include phloretin and trilobatin wherein the weight ratio of phloretin to trilobatin is from about 1 : 1 to about 3: 1. The concentration of phloretin in such a composition may be about 5 ppm to about 150 ppm. The combination of phloretin and trilobatin may remove one or more negative characteristics of the composition.
