NMR Characteristics and Crystal Structure of Cytarabine HepDirect Prodrug MB07133

The structure of the title compound (MB07133) was determined by one-dimensional (i.e.,1H and13C NMR) and two-dimensional (i.e.,1H-1H COSY, gHSQC and gHMBC) NMR techniques. The1H and13C NMR chemical shifts were assigned. The crystal structure of the compound was determined using X-ray single crystal diffraction. The spectral feature and crystal structure of the compound, as well as the structure-function relationship with respective to its use as a prodrug, were discussed.
