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.

Prepared target (parasite PTR1, DHFR) and off-target (human DHFR) protein receptors for docking studies, in part with conserved structural water sets, and the corresponding preparation routine.

Docking results of pteridine-based compounds in different target PTR1 and DHFR receptors and the off-target human DHFR when treating ligands as flexible and the protein receptors as a rigid-body.

Docking results of pteridine-based compounds in different target PTR1 and DHFR receptors and the off-target human DHFR when using an induced fit docking routine with 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):

alpha-tubulin:

• [dinitroaniline sensitive] T. cruzi - Q27352; T. brucei brucei - Q4GYY5; L. infantum - ...

Creation of homology models of various tubulins from dinitroaniline-sensitive and -resistant species, and a comparative analysis of their electrostatic potential grids overall and in putative binding site regions using PIPSA (Protein Interaction Property Similarity Analysis).
