摘要:
The present invention thus provides a novel family of liposomal compositions (nanocarriers), hereinafter referred to as Tetra-Acidosomes, comprising natural tetrameric acid (TA) lipids and/or novel chemically functionalized tetrameric acid (CFTA) lipids, for drug delivery applications.
摘要:
The present invention relates to an isolated gene coding for the enzyme Glycosyl transferase 2 from Pyrococcus horikoshii OT3, the nucleotide sequence of said gene comprising or consisting of sequence SEQ ID NO : 1, or its homologs from hyperthermophilic Archaea. The present invention also relates to an isolated enzyme Glycosyl transferases 2 encoded by the isolated gene, and to a plasmid vector comprising a gene coding for the enzyme Glycosyl transferase 2 from Pyrococcus horikoshii OT3, the nucleotide sequence of said gene comprising or consisting of the sequence SEQ ID NO : 1, or its homologs from hyperthermophilic Archaea. The invention also relates to a host cell comprising a recombinant polynucleotide encoding Glycosyl transferase 2 from Pyrococcus horikoshii OT3, or its homologs from hyperthermophilic Archaea, to a process for producing sulfated glycosaminoglycans (GAGs), and to sulfated glycosaminoglycans obtained by the process and their use for producing pharmaceutical, cosmetic, nutraceutical or food products.
摘要:
The invention relates to a composition (C 1 ) including: (a) at least one compound of formula (I) in which each of the radicals Z is a hydrogen atom or a monovalent radical (Z 1 ); (b) at least one compound of formula (IV); (c) a compound of formula (V). The invention also relates to a method for preparing said composition and to the use thereof in cosmetics.
