Interprotonic distances were calculated using the full relaxation matrix approach (MARGIGRAS + ) with data obtained from NOESY and ROESY experiments at mixing times of 200 and 400 ms. The conformation in solution was calculated by a restrained molecular mechanics minimization using the SYBYL software and TRIPOS force field; see a) B. A. Borgias, T. L. James, J. Magn. Reson. 1990, 87, 475-487; b) M. Clark, R. D. Cramer III, N. Van Opdenbosch, J. Comput. Chem. 1989, 10, 982-1012.
