Benchtop NMR analysis of piperazine‐based drugs hyperpolarised by SABRE [PDF]
Magnetic Resonance in Chemistry, 2020 AbstractPiperazine‐based drugs, such as N‐benzylpiperazine (BZP), became attractive in the 2000s due to possessing effects similar to amphetamines. Herein, BZP, in addition to its pyridyl analogues, 2‐, 3‐, and 4‐pyridylmethylpiperidine (2‐PMP, 3‐PMP, and 4‐PMP respectively) was subjected to the hyperpolarisation technique Signal Amplification By ...
