- ... Spin-labeled nitroxide derivatives of podophyllotoxin had better antitumor activity and less toxicity than that of the parent compounds. However, the 2-H configurations of these spin-labeled derivatives cannot be determined by nuclear magnetic resonance (NMR) methods. In the present paper, a high-performance liquid chromatography-diode array detection (HPLC-DAD) and a high-performance liquid chrom ...
