Stereospecific synthesis of retinoic acid glucoconjugates, as pseudo-substrates of epidermal β-glucocerebrosidase
摘要:
The synthesis of glucocerebrosides (precursors of skin lipids) analogues bearing the bioactive compound retinoic acid is described; the two diastereoisomeric gluco-conjugates glucose-glycerol-retinoic acid are pseudo-subtrates for the title enzyme.

Potential Neuroprotective Drugs in Cerebral Ischemia: New Saturated and Polyunsaturated Lipids Coupled to Hydrophilic Moieties: Synthesis and Biological Activity
The ganglioside GM1 has neuroprotective effects but is not of therapeutic value because of its lack of bioavailability. Thus, molecules that mimic GM I represent a novel approach to neuroprotection. We have synthesized 19 small GM1-like analogues whose simplified structure includes a hydrophobic saturated or unsaturated moiety linked to a hydrophilic moiety. We report their neuroprotective effects in two distinct models of nerve cell death using hippocampus-derived HT22 cells. We found that several analogues protected the HT22 cells from death at concentrations ranging from 2 to 5 mu M. Additional neuroprotective assays using cortical slices injured by glutamate confirmed these results. Since members of the MAP kinase family are known to be key players in nerve cell survival and death, we characterized the role of these kinases in the neuroprotective mechanisms of the GM1-like analogues. Interestingly, the results indicate that the compounds provide neuroprotection through distinct mechanisms of action.

A pharmaceutical composition including a retinoic acid and a carbohydrate is provided. The pharmaceutical composition may further include a metal ion. Use of the pharmaceutical composition in the manufacture of a medicament for inhibiting infection or replication of a virus or for treating a cancer is also provided. The pharmaceutical composition can enhance the inhibition ability of virus infection and/or replication in comparison with the retinoic acid used only.
