Cosmetic uses and methods for indoline granzyme B inhibitor compounds in compositions with a cosmetically acceptable carrier. Uses and methods for treating, reducing or inhibiting the appearance of ageing in the skin are provided. Also provided are compositions and formulation for cosmetic uses and methods of maintaining a youthful appearance, reducing an appearance of ageing, inhibiting an appearance of ageing, reducing a rate of an appearance of ageing, reducing a skin inelasticity, reducing a rate of increasing skin inelasticity, maintaining a skin elasticity, and increasing the density of hair follicles of a skin of a subjecl. The uses and methods comprise applying/administering an indoline granzyme B inhibitor to a skin, or a portion of a skin of the subject.
The use of penicillin acylase for selective N-terminal deprotection in peptide synthesis

Penicillin acylase from E. coli (EC 3.5.1.11) accepts a broad range of N-phenylacetyl-dipeptide esters as substrates. The enzyme hydrolyses the N-terminal protecting group selectively at room temp. and pH=8.1 without affecting the peptide- or the ester-bonds. Alternatively methyl-, benzyl-, tert-butyl and allyl esters can be cleaved chemically leaving the phenylacetamido moiety intact.

The synthesis of the antimicrobial cyclic peptide xenematide was accomplished by Fmoc solid phase peptide synthesis and the key esterification reaction was achieved using a modified Yamaguchi esterification. Comparison of the opticalrotation and NMR data of the synthesized diastereomers to that of the natural product confirmed the structure of xenematide to be PA-L-[Thr-L-Trp-D-Trp-β-Ala]. (PA = phenylacetyl)
抗菌环肽的合成 塞内马肽通过Fmoc固相肽合成来完成,并且使用改进的Yamaguchi酯化来实现关键的酯化反应。合成的非对映异构体与天然产物的旋光度和核磁共振数据的比较证实了其结构塞内马肽是PA-大号- [Thr-大号-Trp- d -Trp-β丙氨酸]。(PA =苯乙酰基)。
