(a) Correlation of 15N chemical shift (ppm) vs the log (1/IC50) values in HeLa cells of the bpy-derived TRIP complexes (TRIP-3a–TRIP-6a), excluding TRIP-7a in the linear regression. (b) Correlation of the highest C≡O stretching frequency (cm–1) vs the log (1/IC50) values in HeLa cells of the bpy-derived TRIP complexes (TRIP-3a–TRIP-7a). (c) Correlation of the C≡N stretching frequency (cm–1) vs the log (1/IC50) values in HeLa cells of the dmphen-bearing TRIP complexes (TRIP-1a–TRIP-1e). The log (1/IC50) were determined by using the IC50 values in units of M.
