• Optimization of the electrophile of chloronitrobenzamide leads active against Trypanosoma brucei
  作者：Jong Yeon Hwang、David C. Smithson、Gloria Holbrook、Fangyi Zhu、Michele C. Connelly、Marcel Kaiser、Reto Brun、R. Kiplin Guy

  We previously reported the phenylchloronitrobenzamides (PCNBs), a novel class of compounds active against the species of trypanosomes that cause Human African Trypanosomiasis (HAT). Herein, we explored the potential to adjust the reactivity of the electrophilic chloronitrobenzamide core. These studies identified compound 7d that potently inhibited the growth of trypanosomes (EC50 = 120 nM for Trypanosoma b. brucei, 18 nM for Trypanosoma b. rhodesiense, and 38 nM for Trypanosoma b. gambiense) without significant cytotoxicity against mammalian cell lines (EC50 > 25 mu M for HepG2, HEK293, Raji, and BJ cell lines) and also had good stability in microsomal models (t(1/2) > 4 h in both human and mouse). Overall these properties indicate the compound 7d and its analogs are worth further exploration as potential leads for HAT. (C) 2013 Elsevier Ltd. All rights reserved.

  We previously reported the discovery of the activity of chloronitrobenzamides (CNBs) against bloodstream forms of Trypanosoma brucei. Herein we disclose extensive structure activity relationship and structure property relationship studies aimed at identification of tractable early leads for clinical development. These studies revealed a promising lead compound, 17b, that exhibited nanomolar potency against T. brucei (EC50 = 27 nM for T. b. brucei, 7 nM for T. b. rhodesiense, and 2 nM for T. b. gambiense) with excellent selectivity for parasite cells relative to mammalian cell lines (EC50 > 25 mu M). In addition compound 17b displayed suitable physiochemical characteristics and microsomal stability (t(1/2) > 4 h for human and mouse) to justify pursuing in vivo studies.

  4-dihydro-4-oxoquinoline-3-carboxylic acid, were synthesized. The compounds were obtained by use of the Gould-Jacobs route to the quinoline ring system. The required anilines, 3-benzoxazol-2-yl-4-fluorophenylamine and 3-benzothiazol-2-yl-4-fluorophenylamine were obtained by the cyclodehydration reaction of 5-amino-2-fluorobenzoic acid with 2-aminophenol or 2-aminothiophenol respectively using polyphosphoric
