  • Publication number: 20060293540
    Abstract: 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.

  • Publication number: 20060264487
    Abstract: Novel dicationic 3,5-diphenylisoxazole compounds are described. Synthetic routes to these novel compounds are provided. Several of the compounds displayed in vitro activity versus Trypanosoma brucei brucei and Plasmodium falciparum comparable to that of furamidine.

  • Publication number: 20050158785
    Abstract: Asymmetric derivatives of furamidines with one of the phenyl rings of furamidine replaced with a benzimidazole have been found by quantitative footprinting analyses to bind GC containing sites on DNA more strongly than to pure AT sequences. These compounds have been shown to bind in the minor groove at specific GC containing sequences of DNA in a highly cooperative manner as a stacked dimer. Compounds of the present invention find use in selectively binding mixed sequence DNA, and may also be used in methods of regulating gene expression, methods of treating opportunistic infections and cancer, as well as in methods of detecting certain sequences of DNA.

    Abstract: Novel dicationic, heterocyclic triaryl compounds are useful in the treatment of microbial infections, such as Trypanosoma brucei rhodesiense infection and Plasmodium falciparum infection. These compounds are accordingly useful in treating second-stage human African trypanosomiasis. Pharmaceutical formulations comprising these compounds can be used in methods of treating microbial infections.
