Regioselective binding of spermine, N1,N12-bismethylspermine, and N1,N12-bisethylspermine to tRNAPhe as revealed by 750 MHz 1H-NMR and its possible correlation with cell cycling and cytotoxicity

The binding of spermine (SPM), N¹,N12-bismethylspermine (BMS) and N¹,N12-bisethylspermine (BES) to tRNA Phe was studied using ¹H-NMR at 750 MHz. The polyamines were enriched in 13C at the 5-CH2 and 8-CH2 residues and the nuclear Overhauser enhancement (NOE) cross peaks connecting the ¹H-NMR resonanc...
