Figure S1: The binding pockets of the PTP1B, which is shown in surface mode labeled with training set: 1 (A), 2 (B), 3 (C), 4 (D), 5 (E), 6 (F), 7 (G), 8 (H), 9 (I), 10 (J), 11 (K), 12 (L), 13 (M), 14 (N), 15 (O) and 16 (P). Each compound was showed by different colors. Protein: hydrophobic residues (blue) and hydrophilic residues (red). The pictures were prepares using PyMol.

Figure S2: Docking of compounds 1 (A), 2 (B), 3 (C), 4 (D), 5 (E), 6 (F), 7 (G), 8 (H), 9 (I), 10 (J), 11 (K), 12 (L), 13 (M), 14 (N), 15 (O) and 16 (P) into the active site of PTP1B with key amino acid residues in all ligand binding poses. The key amino acid residues: nitrogen (blue), oxygen (red), carbon (green) and sulfur (gold). Compounds: nitrogen (blue), oxygen (red), carbon (white) and sulfur (gold). The pictures were prepares using PyMol.
