All amino groups in a proteinous antitumor antibiotic, neocarzinostatin, were reacted with succinic anhydride yielding bis-N-succinyl neocarzinostatin which retained biological activity in vitro against human cell lines and a bacterium. Amino groups in neocarzinostatin do not appear to play an important role in the activity.
蛋白质类抗肿瘤抗生素新制癌菌素中的所有氨基与琥珀酸酐反应,生成双 -N-琥珀酰新制癌菌素,其在体外对人细胞系和一种细菌仍保留生物活性。新制癌菌素中的氨基似乎在活性方面不发挥重要作用。
