10-Hydrazino-BODIPY, BoNHNH2 , presents slow rotation about the C10-NH bond that results in anisochronous 1 H and 13 C NMR signals. The assignment of the different signals has been made using traditional two-dimensional methods as well as spin-spin coupling constants and confirmed by DFT calculations (B3LYP) using the 6-311++G(d,p) basis set. The rotational barrier has been determined in three pairs of proton signals and compared with the calculated barrier.Pembrolizumab is an immune checkpoint inhibitor designed to block the interac
