  Synthesis and Antitubulin Activity of N- and N⁴-Substituted 3,5-Dinitro Sulfanilamides against African Trypanosomes and Leishmania

  摘要：

  Thirty analogues of N-1-phenyl-3,5-dinitro-N-4,N-4-di-n-propylsulfanilamide (GB-II-5, compound 3), a new antikinetoplastid antimitotic agent, have been synthesized and evaluated. The addition of simple functional groups to the N1 aromatic ring generally decreases antiparasitic and antimitotic potency, but placement of a dibutyl substituent at the N4 nitrogen to give N-1-phenyl-3,5-dinitro-N-4,N-4-di-n-butylsulfanilamide (compound 35) augments antitrypanosomal and antileishmanial activity. Compound 35 possesses IC50 values of 0.12 and 2.6 muM against cultured T. brucei and L. donovani amastigote-like forms, surpassing the activity of compound 3 against these parasites by 3.4- and 1.9-fold, respectively. Compound 35 inhibits the assembly of leishmanial tubulin with an IC50 of 6.9 muM and displays antimitotic effects in cultured T brucei as assessed by flow cytometry, but shows little effect on purified mammalian tubulin, and displays 100-fold selectivity for trypanosomes over two mammalian cell lines. Although 3 and 35 were not effective in initial in vivo antitrypanosomal assays, the in vitro potency and ;selectivity of these compounds make N-1-aryl-3,5-dinitro-N-4,N-4-dialkylsulfanilamides a promising new class of antikinetoplastid agents that act on parasite tubulin.
