  Assessment of Chemoselective Neoglycosylation Methods Using Chlorambucil as a Model

  摘要：

  To systematically assess the impact of glycosylation and the corresponding chemoselective linker upon the anticancer activity/selectivity of the drug chlorambucil, herein we report the synthesis and anticancer activities of a 63-member library of chlorambucil-based neoglycosides. A comparison of N-alkoxyamine-. N-acylhydrazine-, and N-hydroxyamine-based chemoselective glycosylation of chlorambucil revealed sugar- and linker-dependent partitioning among open- and closed-ring neoglycosides and corresponding sugar-dependent variant biological activity. Cumulatively, this study represents the First neoglycorandomization of a synthetic drug and expands our understanding of the impact of sugar structure upon product distribution/equilibria in the context of N-alkoxyamino-, N-hydroxyamino-, and N-acylhydrazine-based chemoselective glycosylation. This study also revealed several analogues with increased in vitro anticancer activity, most notably D-threoside 60 (NSC 748747), which displayed much broader tumor specificity and notably increased potency over the parent drug.

  摘要：

  N-Acetylmuramyl-L-alanyl-D-isoglutamine (MDP) 和十三个新的类似物是通过常规有机化学方法合成的，使用二环己基碳二亚胺-N-羟基-5-降冰片烯-2,3-二甲酰亚胺作为偶联剂。测定了它们在豚鼠中诱导对 N-乙酰基-3-(4-arsonophenylazo)-L-酪氨酸的迟发型超敏反应的能力。结果表明，与 MDP 中乳酸部分相邻的 α-氨基酸的存在对于高生物活性很重要，缬氨酸类似物具有最有利的作用。讨论了构效关系。

  N-Acetylmuramyl-L-alanyl-D-isoglutamine (MDP) and thirteen new analogs were synthesized by the conventional organic chemical procedure using dicyclohexylcarbodiimide-N-hydroxy-5-norbornene-2,3-dicarboximide as a coupling agent. Their ability to induce delayed-type hypersensitivity to N-acetyl-3-(4-arsonophenylazo)-L-tyrosine in guinea pigs was assayed. The results indicate that the presence of an α-amino
