标题:Photochemical Desulfurization Of Thiols And Disulfides
摘要:A Visible Light-Induced Desulfurization Process For Thiols And Disulfides Using Triethylphosphite And Triethylborane Is Reported. The Reaction Can Be Effected On A Range Of Organic Molecules Having Either Primary,Secondary Or Tertiary Thiol Groups And Disulfides Without The Need Of Protecting Groups. Thus,After Treating L-Cystine 7,L-Cystine Dimethylester 8,Thioctic Amide 9 And Glutathione Disulfide 10,First With Tributylphosphine,Later With Triethylborane/triethylphosphite Under Irradiation In A One-Pot Reaction,The Corresponding Desulfurized Compounds L-Ala,L-Ala,1-octanamide And Gamma-L-Glu-L-Ala-Gly,Respectively,Are Prepared In High Yields With Retention Of Configuration.

标题 :Composition for enhancing lipid production, barrier function, hydrogen peroxide neutralization, and moisturization of the skin
发明人：PAUL HARBHAJAN S
权利人:BIOMED RES & TECHNOLOGIES INC
摘要:Increased production of skin lipids, increased barrier function, hydrogen peroxide neutralization, prevention of loss of the natural moisturizing factor from the stratum corneum and moisturization of the skin is provided by a topically applicable composition which includes one or more components selected from the group consisting of branched chain amino acids, derivatives of branched chain amino acids and mixtures thereof, which one or more components are capable of being catabolized in epidermal cells to form lipid precursors for epidermal lipid synthesis. The composition can also include one or more enzyme activators which increase the rate of catabolism of the one or more components.
