(A) Selective 1D ¹H-¹H NOE (δ_H expansion from 6.0 to 3.0 ppm) spectra at different mixing times (50, 100, 150, 200, 250 ms), (B) ¹H-¹H NOE build up curves at the different mixing times, and (C) ¹H-¹H NOESY (δ_H-δ_H expansions from 6.0–3.5 to 3.5–6.0 ppm) spectrum of Mh-P2 acquired on 500 MHz spectrometer at 50 °C and 150 ms mixing time
