  Portage transport of sulfanilamide and sulfanilic acid

  摘要：

  Sulfanilic acid, in contrast to sulfanilamide, has poor in vitro antibacterial activity. Paradoxically, it has been shown to be a more effective inhibitor than sulfanilamide of dihydropteroic acid synthase. In order to circumvent the presumed permeability barrier to sulfanilic acid, advantage was taken of the technique of portage transport. Derivatives of the compound were prepared in which it was linked via its primary amino group to the alpha-carbon of glycine residues in di- and tripeptides. L-Alanyl-L-alanyl-L-2-[(4-sulfophenyl)amino]glycine proved to be 207 times more potent than sulfanilic acid and 8 times more active than either sulfanilamide or L-alanyl-L-alanyl-L-2-[[4-(aminosulfonyl)-phenyl]amino]glycine when tested against Escherichia coli. These findings confirm that the weak in vitro activity of sulfanilic acid is due to its limited ability to penetrate the bacterial membrane. They also emphasize the ability of portage transport to reveal therapeutic capability that had been attenuated by poor drug permeation.

  具有独特的氨基，半胱氨酸和半硫代氨基官能团的5'-核苷单磷酸酯衍生物的合成：一类新的5'-肽基核苷酸

  摘要：

  已开发出许多合成上有用的转化形式，以产生新的5'-肽基核苷单磷酸类似物，这些类似物结合了敏感的磷酸氨基，半胱氨酸或半硫代氨基缩醛官能团。所采用的策略需要二肽之间的偶联，从而封闭了一个反应性的Cα-官能化的甘氨酸残基和磷酸或硫代磷酸酯基团。这些进展为制备α-磷酸化假肽以及核苷单磷酸酯模拟物带来了潜在的强大而通用的方法学。所得的缀合物对于从药物开发到合成生物学的各种重要应用都是令人感兴趣的，它们是用于异源生物信息系统酶促合成的前核苷酸或人工结构单元。

  As an approach to the development of antimicrobial agents, a novel peptide carrier system was designed, based on the chemical instability of alpha-substituted glycine analogues, with the explicit intent of actively transporting therapeutically useful compounds into microbial cells. Peptides containing 5-fluorouracil (5-FU) linked to the peptide backbone were selected to test the feasibility of this new delivery system. These peptide conjugates were designed such that they would be substrates for both the microbial peptide permeases and peptidases. After entry into cells, enzymatic hydrolysis of the peptide generates an unstable alpha-(5-FU)-glycine that spontaneously decomposes to release 5-FU. The 5-FU-peptide conjugates were tested for antifungal (Candida albicans) and antibacterial (Escherichia coli) activity and were found to have antimicrobial activities comparable to free 5-FU. Noninhibitory peptides antagonized the antimicrobial activities of the 5-FU-peptide conjugates but not of free 5-FU, a result consistent with peptide transport mediated entry of the peptide conjugates into cells. Further support for this conclusion was provided by the finding that biological activities were dependent upon peptide stereochemistry.
