Pharmacophore perception strategy has been employed to identify key chemical features responsible for the biological activity for <jats:italic>TbPTR1<\/jats:italic>. The findings suggest that three different pharmacophore features can be associated with <jats:italic>T. brucei<\/jats:italic> anti\u2010PTR1 activity namely: H\u2010bond donors (D), Hydrophobic aromatic (H) and Ring aromatic (R). The resulting hypothesis is able to predict the activity of other existing <jats:italic>TbPTR1<\/jats:italic> inhibitors with a correlation coefficient (<jats:italic>r<\/jats:italic>) of 0.89. An in silico database screening, based on the best hypothesis, has been used to identify some potential nanomolar range <jats:italic>TbPTR1<\/jats:italic> inhibitors. These compounds were then checked by molecular docking and subjected to ADMET analysis. Further, a detailed comparison of the pharmacophore behavior and differential analysis of binding pockets of <jats:italic>T. brucei<\/jats:italic> and <jats:italic>L. major<\/jats:italic> was made which revealed subtle differences in terms of their shape and charge properties. This investigation can form the basis for tweaking the specificity of compounds for generating new improved species specific inhibitor molecules for Pteridine reductase in these different parasitic protozoans.<\/jats:p>","DOI":"10.1002\/minf.201300023","type":"journal-article","created":{"date-parts":[[2014,2,3]],"date-time":"2014-02-03T07:56:36Z","timestamp":1391414196000},"page":"124-134","source":"Crossref","is-referenced-by-count":4,"title":["Pharmacophore Mapping, In Silico Screening and Molecular Docking to Identify Selective <i>Trypanosoma brucei<\/i> Pteridine Reductase Inhibitors"],"prefix":"10.1002","volume":"33","author":[{"given":"Divya","family":"Dube","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sujata","family":"Sharma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tej P.","family":"Singh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Punit","family":"Kaur","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,2,2]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/nrd1824"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.46.2.434-437.2002"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/00001432-200412000-00009"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.00225-09"},{"key":"e_1_2_6_5_2","first-page":"876","volume":"11","author":"Paine M.
