Figure 3.
1H-NMR (A) and13C (B) spectra of glutaryl-LND derivative. NMR Spectra were scanned in DMSO-d6 on a Bruker NMR spectrometer operating at 500 MHz for 1H and 125.76 MHz for 13C. Chemical shifts are expressed in δ-values (ppm) relative to TMS as an internal standard. D2O was added to confirm the exchangeable protons.
