| simulated annealing | Structure calculations utilized 1169 NOE-based distance constraints, of which 54 were intermolecular; 176 dihedral angle constraints; and 48 hydrogen bond constraints. The piperazinyl moiety of the inhibitor gave no NOEs, hence the positions of its atoms are not known and the stereochemistry is not rigorously established. | Felix |
