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.
