权利人:MALLINCKRODT INC
摘要:An improved method of making a substituted pyrazolopyrimidine. The method comprises reacting a aminopyrazole compound or a salt thereof with a substituted 1-oxo-2-propenyl-arene(-heterocycle) or a salt thereof under acidic conditions in a reaction medium including a two-phase mixture of an aqueous solution and a water-immiscible organic liquid. Specific substituted pyrazolopyrimidines include N-[3-(3-cyanopyrazolo[1,5-a]pyrimidin-7-yl)phenyl]-N-ethylacetamide and N-methyl-N-(3-{3-[2-thienyl-carbonyl]-pyrazolo[1,5-a]-pyrimidin-7-yl}phenyl)acetamide.

标题 :Skin Darkening (Sunless Tanning) Compositions Based on Enhancement of Melanin Synthesis by Tyrosinase Promoters
发明人：GUPTA SHYAM K
权利人:BIODERM RESEARCH
摘要:This invention discloses skin darkening (sunless tanning) compositions based on enhancement of melanin synthesis by tyrosinase enzyme by providing essential substrates for tyrosinase as well as the essential elements to activate the active-site of tyrosinase enzyme. These compositions thus also act as promoters of tyrosinase enzyme.

标 题 :Use of composition comprising stem cell-derived exosome as effective ingredient in strengthening skin barrier and improving skin barrier function

权利人:EXOCOBIO INC
摘要:A composition for strengthening skin barrier or improving skin barrier function is able to improve objective indicators related to the protection of skin barrier, the strengthening of skin barrier, and/or the improvement of skin barrier function. The composition exhibits the effects of increasing the amount of ceramides, dihydroceramides and sphingoid bases, increasing the activities of enzymes that are involved in the synthesis thereof, and decreasing the activities of enzymes that are involved in the degradation thereof. In addition, the composition is able to restore skin barrier function by reducing TSLP, IL-4, and IL-13 which are closely associated with skin barrier damage, and thus interrupting a vicious circle in which the lipids and proteins contributing to skin barrier decrease.

摘要:The present invention relates to dermocosmetic formulations for use in combating skin aging, especially photoaging. The present invention promotes the increase of the synthesis of collagen, elastin and glycosaminoglycans (GAG), in addition to significantly increase the activity of the superoxide dismutase enzyme (SOD) and the cell proliferation.
