Antiparasitic dinitroaniline-ether phospholipid hybrids

The New Medicines for Trypanosomatidic Infections - NMTrypI project aimed at obtaining new candidate drugs against Trypanosomatidic infections with appropriate efficiency from the lead phase to the final preclinical phase that are more accessible to patients.

Induced fit docking studies of the dinitroaniline parent trifluraline and the newly designed dinitroaniline-etherphospholipid hybrids against different potential binding sites in monomeric and multimeric kinetoplastid tubulin receptors.

Sequence and electrostatic potential analyses to identify sites in tubulins that differ between dinitroaniline-sensitive and dinitroaniline-resistant species.

Prepared multimeric tubulin protein receptors for docking studies, generated by alignment of two identical models of alpha-tubulin on alpha-tubulin chains of two neighboring protofilaments.

Docking results of trifluraline and dinitroaniline-etherphospholipid hybrids against different kinetoplastid alpha-tubulin receptors with an induced fit docking routine. The docking protocol involves an initial crude ligand placement step, subsequent receptor optimization in response to ligand binding, and another docking step into the optimized receptor.

Alignments of various alpha-tubulin and beta-tubulin sequences from dinitroaniline-sensitive and dinitroaniline-resistant species. Sequences were retrieved from UniProt with the identifiers listed below and subjected to a multiple sequence alignment using ClustalOmega (ebi.ac.uk/Tools/msa/clustalo/; ClustalOmega webserver, last accessed 16-02-23):
