TZD structures. The TZDs are hydrophobic, with octanol–water clogP values (calculated from the experimental logD7.4) and logD7.4 (experimental) of: 5.3 and 4.2 for troglitazone, 2.8 and 2.6 for rosiglitazone, 3.3 and 3.1 for pioglitazone, and 5.7 and 4.6 for ciglitazone (Giaginis et al., 2007). Calculated pKa is 6.4 (±0.5) for all of the TZDs (Giaginis et al., 2007). Structures were drawn using MarvinSketch 5.0.3 (ChemAxon).
