Synthesis and antioxidant activity of curcumin analogs
AbstractNumerous biological activities including antioxidant, antitumor, anti-inflammation, and antivirus of the natural product curcumin were reported. However, the clinical application of it was significantly limited by its instability, poor solubility, less body absorbing, and low bioavailability. This review focuses on the structure modification and antioxidant activity evaluation of curcumin.

Green synthesis and biological activities of silver
Abstract. The extract of Carpesium cernuum whole plant was successfully used as a green factory for the synthesis of silver nanoparticles in a one-step, one-pot process. The extract efficiently reduced silver ions to spherical silver nanoparticles. The size was measured as 13.0 ± 0.2 nm from high resolution transmission electron microscopic images.

An Updated Review of Tyrosinase Inhibitors
Recently, piceatannol (3,5,3′,4′-tetrahydroxy-trans-stilbene, Figure 4a), isolated from grapes and red wine, showed 32.7-fold antimonophenolase activity of kojic acid toward mushroom tyrosinase . The hydroxyl positions of the structure of piceatannol, which contains o -(3′,4′-)dihydroxy groups, are significantly different from other naturally found hydroxystilbenes.
