Novel Bioconjugates of Aminolevulinic Acid with Vitamins
摘要:
5-Aminolevulinic acid (ALA) and derivatives thereof have been successfully used in photodynamic cancer therapy (PDT). The synthesis of novel bioconjugates combining ALA with two lipophilic and one hydrophilic vitamins is reported. The new bioconjugates allow studying the potential synergies between the two components in PDT. The synthetic methodology is robust giving the bioconjugates in good to satisfactory yield.
The efficient synthesis of two stable, easily handled precursors of 5-aminolevulinate is reported. These precursors are stable to the chemical transformation needed for the synthesis of bioconjugates and can be readily deprotected in good yields.

delta-aminolevulinic acid (1) moieties on the narrow periphery of a beta-cyclodextrin (beta-CD) derivative through hydrolysable bonds was implemented, in order to generate a water-soluble, molecular/drugcarrier with the capacity to undergo intracellular transformation into protoporphyrin IX (PpIX), an endogenous powerful photosensitizer for photodynamic therapy (PDT). The water-soluble derivative2 was prepared by
