  有机铝烷介导的抗坏血酸和异抗坏血酸衍生物的异构化

  摘要：

  当用三异丁基铝处理时，l-抗坏血酸2a和d-异抗坏血酸2b的衍生物部分发生差向异构化，生成l-异抗坏血酸ent - 2b，ent -10b或d-抗坏血酸ent - 2a ，ent -11a分别。保护基的完全除去是通过对亚甲基缩醛ent -10和ent- 11a进行氢解来实现的。该反应导致d抗坏血酸ENT -1a或1-异抗坏血酸ENT分别-1b。此外，四种丙酮化物2被臭氧分解，酯交换，最后催化氢化转化为苏糖醛和赤藓酸缩酮9。

  Collagen is critical for skin strength and elasticity, and its degradation leads to wrinkles that accompany aging. Based emphasis on the aesthetics, we tried to make a new compound that can highly stimulate collagen biosynthesis and synthesized ascorbyl conjugated peptide that is a complex form connected by succinoyl linker. We conducted several in vitro and in vivo experiments to identify if the compound has a potent activity, comparing to the ascorbic acid only for collagen biosynthesis. Our in vitro and in vivo result identified that ascorbyl conjugated peptide can stimulate collagen biosynthesis in human dermis and is assumably stable in the rat skin extracts. In conclusion, we strongly suggest that ascorbyl conjugated peptide can be used as a main ingredient for cosmetic products as well as wound healing agents. (C) 2008 Elsevier Ltd. All rights reserved.

  The synthesis, extended molecular modelling and cytotoxic effects of 6-amino-6-deoxy-L-ascorbic acid derivatives are described. For structure-function considerations, comparative conformational analysis was performed and X-ray structure analysis, molecular mechanics and molecular dynamics simulations were used in the search for the bioactive conformation(s). The cytotoxic effect of N,N-dimethyl-6-amino-6-deoxy-L-ascorbic acid on human tumour cell lines (Hep2, MiaPaCa2, HeLa) and on diploid human fibroblast (WI 38) was examined. The dimethylamino derivative of ascorbic acid expressed a stronger cytotoxic effect than ascorbic acid itself. This effect was cell-specific and dose dependent. The treatment of the cells with N,N-dimethyl-6-amino-6-deoxy-L-ascorbic acid probably resulted in apoptosis, evidenced by characteristic morphological changes and ladder DNA fragmentation. Apoptosis was not mediated by c-Myc or p53 proteins.
