标题:与锰络合提高木犀草素的抗氧化活性,抗菌活性和降血糖作用(II)及其对黄嘌呤氧化酶的抑制动力学
摘要:本研究旨在通过与锰(II)的络合提高木犀草素的生物活性.通过紫外可见光谱,红外光谱,热重分析和元素分析来评估木犀草素和锰(II)离子与螯合位点的相关相互作用.研究并比较了木犀草素-锰(II)配合物对其母体木犀草素的抗氧化活性,降血糖作用和抗菌活性,以及它们对黄嘌呤氧化酶的抑制作用.光谱数据表明与锰(木犀草素发生反应ii)阳离子通过两个木犀草素分子中的5-羟基和4-羰基的螯合位点.锰(II)阳离子与木犀草素络合后,抗氧化和抗菌活性得到增强.抑制作用试验发现,木犀草素和木犀草素-锰(II)配合物以竞争性方式可逆地抑制黄嘌呤氧化酶.木犀草素-锰(II)复合物通过增加肝脏组织中的葡萄糖消耗,具有比木犀草素更显着的降血糖作用.

标题 :Cosmetic composition for increasing hyaluronic acid synthesis in skin and its use for repairing wrinkles
发明人：PUJOS MURIEL; BERNINI DOROTHEE; ROBERT CECILE; DOUCET OLIVIER
权利人:COTY GERMANY GMBH
摘要:The present invention relates to a skin composition which has an excellent effect on smoothing or repairing wrinkles. The composition comprises Palmitoyl Tripeptide-38 (Palmitoyl-Lysyl-Dioxymethionyl-Lysine) and Piper nigrum (Pepper) seed Extract which combination has been found to result in a synergistic effect on hyaluronan synthase 1 (HAS1) mRNA expression in human fibroblasts. The hyaluronan synthase is responsible for the synthesis of hyaluronan (hyaluronic acid) in skin. Hyaluronic acid is a constituent of the extracellular matrix of the skin and responsible for space filling, tissue repair and retention of moisture.

标题 :Electrocatalytic synthesis of dihydrochalcones
发明人：REDKO MIKHAIL; SAFFRON CHRISTOPHER M; JACKSON JAMES E
权利人:UNIV MICHIGAN STATE
摘要:The disclosure relates to methods of forming a dihydrochalcone using electrocatalytic dehydrogenation. In particular, the disclosure relates to methods of forming a dihydrochalcone electrocatalytically hydrogenating (ECH) a reactant compound over a catalytic cathode in a reaction medium having a non-alkaline pH value, thereby forming a dihydrochalcone product; wherein the reactant compound has a structure according to Formula (I). The method can be used to prepare dihydrochalcone sweeteners, such as, for example, naringin dihydrochalcone and neohesperidin dihydrochalcone.

标 题 :Topical compositions for regulating the oily/shiny appearance of skin
发明人：BIEDERMANN KIMBERLY A; SCHUBERT HARRY L; PARRAN JR JOHN J
权利人:PROCTER & GAMBLE
摘要:The present invention relates to methods for inhibiting sebaceous gland activity in mammalian skin comprising administration of a topical composition comprising dehydroacetic acid or pharmaceutically acceptable salts thereof, and a dermatologically-acceptable carrier. The present invention also relates to methods and topical compositions further comprising agents which regulate the oily and/or shiny appearance of skin, and agents which treat acne and related skin disorders in mammalian skin and scalp. Methods of reducing sebum synthesis with the use of dehydroacetic acid, methods of regulating the oily and/or shiny appearance of skin, and methods of treating acne and other skin disorders are also encompassed by the present invention.
