A method of treating a
Mycobacterium tuberculosis
infection in a subject in need thereof by administering to the subject an effective amount of a cationic substituted benzofuran compound. Methods of treating microbial infections, including infections from protozoan pathogens, such as
Leishmania donovani, Trypanosoma brucei rhodesiense
, a
Trypanosoma cruzi
, and
Plasmodium falciparum
, and fungal pathogens, such as
Candida albicans, Aspergillus fumigatus
, and
Cryptococcus neoformans
, in a subject in need thereof by administering to the subject an effective amount of a cationic substituted benzofuran compound. Methods of synthesizing novel cationic substituted benzofuran compounds and the novel compounds themselves.

Forty three cationic bisbenzofurans were synthesized either by interaction of o-hydroxyaldehydes with alpha-halogenated ketones followed by intramolecular ring closure or by a copper- or palladium-mediated heteroannulation of substituted o-iodophenols with terminal acetylenes. In vitro antiprotozoalactivities of compounds 1-43 against Trypanosoma brucei rhodesiense, Plasmodium falciparum, and Leishmania
