NMR Refinement
Method	Details	Software
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
