A simplified approach to the synthesis of 2-polyamine linked-monoindolylmaleimides has been achieved, leading to a new series of trypanothione reductase inhibitors. The conditions of access to N, 2-bis (polyamine)-3-monoindolylmaleimides and N, N'-bis ( monoindolylmaleimide) polyamines are described. Measured inhibitory activities towards trypanothione reductase from Tryanosoma cruzi show the importance of both aromatic ...
