Three topochemical indices, Wiener's topochemical index \u2014 a distance-based topochemical descriptor, molecular connectivity topochemical index \u2014 an adjacency-based topochemical descriptor, and eccentric connectivity topochemical index \u2014 an adjacency-cum-distance-based topochemical descriptor, were used for the present investigation. The values of the Wiener's topochemical index, molecular connectivity topochemical index, and eccentric connectivity topochemical index were computed for each of the 45 analogs constituting the data set using an in-house computer program. The predicted log P values using leave-one-out (LOO) procedure exhibited a q<jats:sup>2<\/jats:sup> of 0.72, 0.70, and 0.71 with reported log P values for Wiener's topochemical index, molecular connectivity topochemical index, and eccentric connectivity topochemical index, respectively. Separate models were developed using training set and log P of each analog in the independent test set was predicted using these models. The correlation of predicted log P values with the reported values, for independent test set, were in good agreement with those predicted using LOO procedure. <\/jats:p>","DOI":"10.1142\/s021963360700309x","type":"journal-article","created":{"date-parts":[[2007,9,4]],"date-time":"2007-09-04T11:33:08Z","timestamp":1188905588000},"page":"435-448","source":"Crossref","is-referenced-by-count":15,"title":["TOPOCHEMICAL MODELS FOR THE PREDICTION OF LIPOPHILICITY OF 1,3-DISUBSTITUTED PROPAN-2-ONE ANALOGS"],"prefix":"10.1142","volume":"06","author":[{"given":"HARISH","family":"DUREJA","sequence":"first","affiliation":[{"name":"Faculty of Pharmaceutical Sciences, M.D. University, Rohtak 124001, India"}]},{"given":"VIPIN","family":"KUMAR","sequence":"additional","affiliation":[{"name":"Faculty of Pharmaceutical Sciences, M.D. University, Rohtak 124001, India"}]},{"given":"SUNIL","family":"GUPTA","sequence":"additional","affiliation":[{"name":"Faculdade de Ci\u00eancias e Tecnologia, Universidade Nova de Lisboa, Quinta da Torre, 2829-516 Caparica, Portugal"}]},{"given":"ANIL KUMAR","family":"MADAN","sequence":"additional","affiliation":[{"name":"Faculty of Pharmaceutical Sciences, M.D. University, Rohtak 124001, India"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1016\/S0169-409X(00)00129-0"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1021\/cr950202r"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1021\/ci000134w"},{"key":"rf4","volume-title":"Chemical Graph Theory","author":"Trinajstic N.","year":"1983"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1080\/1062936021000043409"},{"key":"rf6","volume-title":"Molecular Connectivity in Structure-Activity Analysis","author":"Kier L.
