Sci. 2003, 22(2), 247-257131 compounds and their 'Fraction Absorbed' values have been obtained from the table given in the paper. Some compounds had multiple values reported (as obtained from various references). These have been averaged and provided by us in the SDF and AMP files. The "Sanghvi_values.txt" file contains all data (as reported in Table 1) and "Sanghvi_avg_values.txt" contains averaged data for compounds with multiple entries (as reported in Table 2). "Benserazide, HCl" was retrieved as "Benserazide", "Ceftriaxone, Na" as "Ceftriaxone", "Foscarnet, Na" as "Foscarnet", "L-Dopa" as "Levodopa", "L-Leucine" as "Leucine" and "Triacrilast" as "Tiacrilast". The last compound was found to be mispelt as checked from the original reference.

Fragment removed from "timolol maleate" during "wash". AMP file has a "Label" column indicating 9 compounds used as a "Cross-Validation Set" and 10 compounds used as an "External Prediction Set" by the authors. Rest of the compounds are labeled as "Training Set".
