This was accompanied by chemical shifts at 0.9 p.p.m. and 1.26 p.p.m. for MDTG, representing the 10 (CH3R) and 20 (RCH2R) protons in the aliphatic fatty-acid chain. Chemical shifts at two.73 p.p.m. and 1.8 p.p. m. correspond to protons in the C and C positions of the aliphatic ester (COOR) alkyl chain (Supplementary Fig. 1b). 13C NMR spectral analysis of MDTG shows all 34 carbon atoms present inside the modified drug (Supplementary Fig. 1c). ESI-MS evaluation shows the precise mass of MDTG to be 629.33 (one hundred ), with daughter ion peaks at 630.33 (36.eight ) and 631.33 (3.9 ) (Supplementary Fig. 1d).
