  Synthesis and characterization of the aqueous solution chemistry of the food-derived carcinogen model N-acetoxy-N-(1-methyl-5H-pyrido[4,5-b]indol-3-yl)acetamide and its N-pivaloyloxy analogue

  摘要：

  We report the synthesis of N-acetoxy-N-(1-methyl-5H-pyrido[4,5-b]indol-3-yl)acetamide, 7, its N-pivaloyloxy analogue, 9, and improved synthesis of indole-2-acetonitrile, 3 (70% in five steps from indole-2-carboxylic acid), the carcinogenic amine Trp-P-2, 4 (40% from 3), and the nitro compound, 5 (40% from 4 by oxidation with H,02 using MO(CO)6 catalyst). In aqueous solution at neutral pH, 7 primarily undergoes C-O bond cleavage to yield the hydroxamic acid, 8, but under the same conditions the sterically hindered 9 decomposes predominately by N-O bond cleavage with a pH independent rate constant that is 7.5-fold smaller than that for 7. In the pH range 0.5-7.0 three different processes for the decomposition of 9 were detected by kinetics. Only the process that dominates at neutral pH generates a nitrenium species that can be trapped by N ((3)) over bar. (C) 2003 Elsevier Ltd. All rights reserved.

  3-Amino-1-methyl-5H-pyrido [4, 3-b] indole (Trp-P-2) is a mutagen/carcinogen isolated from a pyrolysate of L-tryptophan. The active metabolite of Trp-P-2, 3-hydroxyamino-1-methyl-5H-pyrido [4, 3-b] indole (N-OH-Trp-P-2), was synthesized and the chemical reactions of N-OH-Trp-P-2 with deoxyribonucleic acid were investigated. The structure of the nucleic acid base covalently bound with Trp-P-2 was elucidated as 3-(C8-guanyl) amino-1-methyl-5H-pyrido [4, 3-b] indole (Gua-Trp-P-2) by comparison with a synthetic sample. The initial chemical events in carcinogenesis caused by Trp-P-2 were established.
