cost-effective procedure has been devised for the preparation of urethane-protected 5-aminolaevulinic acid (5-ALA) dipeptide ester derivatives which avoids problems associated with the instability of 5-ALA under basic conditions. The procedure is also applicable to the direct synthesis of N-(α)-acetyl amino acid-ALA dipeptides in high enantiomeric purity as potential novel prodrugs for photodynamic therapy
已经设计了一种有效且具有成本效益的方法来制备氨基甲酸酯保护的5-氨基戊二酸(5-ALA)二肽酯衍生物,该方法避免了在碱性条件下与5-ALA的不稳定性相关的问题。该方法还适用于以高对映体纯度直接合成N-(α)-乙酰基氨基酸-ALA二肽,作为光动力疗法(PDT)的潜在新药。
