S-MGB-234 is a minor groove binder utilized for the treatment of Animal African Trypanosomiasis (AAT). It exhibits exceptional in vitro efficacy against the primary causative agents of AAT, namely Trypanosoma congolense and Trypanosoma vivax. Moreover, S-MGB-234 does not demonstrate cross-resistance with existing diamidine drugs and is not internalized through the transporters employed by diamidines.
