The antitumour drug temozolomide has been synthesized isotopically labelled with NMR active nuclei at a variety of sites and all its 13C and 15N NMR spectral resonances have been assigned. At low pH a site of protonation has been identified which accounts for the acid stability of the drug
抗肿瘤药物替莫唑胺已在各个位置被NMR活性核同位素标记,并且已指定了其所有13 C和15 N NMR光谱共振。在低pH值下,已鉴定出质子化的位点,这说明了药物的酸稳定性
