  Dicationic phenyl-2,2′-bichalcophenes and analogues as antiprotozoal agents

  摘要：

  A series of phenyl-2,2'-bichalcophene diamidines 1a-h were synthesized from the corresponding dinitriles either via a direct reaction with LiN(TMS)(2), followed by deprotection with ethanolic HCl or through the bis-O-acetoxyamidoxime followed by hydrogenation in acetic acid and EtOH over Pd-C. These diamidines show a wide range of DNA affinities as judged from their Delta T-m values which are remarkably sensitive to replacement of a furan unit with a thiophene one. These differences are explained in terms of the effect of subtle changes in geometry of the diamidines on binding efficacy. Five of the eight compounds were highly active (below 6 nM IC50) in vitro against Trypanosoma brucei rhodesiense (T. b. r.) and four gave IC(50)values less than 7 nM against Plasmodium falciparum (P. f.). Only one of the compounds was as effective as reference compounds in the T. b. r. mouse model for the acute phase of African trypanosomiasis. (C) 2010 Elsevier Ltd. All rights reserved.

  Novel dicationic bichalcophene compounds are described. The presently disclosed novel dicationic bichalcophene compounds exhibit in vitro activity versus Trypanosoma brucei rhodesiense, Plasmodium falciparum , or Leishmania donovani comparable to that of pentamidine and furamidine. Some of the novel dicationic bichalcophene compounds displayed good activity in vivo in a murine model of a Trypanosoma brucei rhodesiense infection.

  Dicationic compounds that are highly selective for binding G-quadruplex DNA are described. Several compounds exhibit groove binding toward G-quadruplex DNA and in vitro and in vivo activity versus Trypanosoma brucei rhodesiense. The compounds represent novel drugs for the treatment of cancer, malaria, leishmania, and trypanosomiasis.
