  • Publication number: 20140350304
    Abstract: Disclosed is a chalcone composition for treating diabetes and metabolic syndromes. In particular, the chalcone compound bound with 2-halogen in ring A significantly decreases the blood glucose level in the in vitro anti-diabetic effect experiment. In the in vivo animal model, the leading chalcone compound can prevent the progression of diabetes and control the blood glucose level, and there is no significant difference in the gains in body weight. Throughout the seven-week administration, there are no hepatic or renal toxicity observed.

  • Patent number: 5230874
    Abstract: The present invention relates to novel sunscreen agents which have the ability to absorb both UVA and UVB wavelength radiation. The sunscreen agents comprise a specific type of UVA-absorbing chromophore covalently bonded to a specific type of UVB-absorbing chromophore. The chromophore moieties are covalently bonded together such that the electron systems of these moieties are not directly coupled.The present invention further relates to sunscreen compositions containing the hereinbefore described type of sunscreen agents. Furthermore, the present invention relates to methods for protecting the skin of humans or lower animals from the effects of UVA and UVB wavelength radiation. This method comprises topically applying to the skin an effective coating of a sunscreen composition of the present invention.
