Nitration of acronycine (1) and 6-demethoxyacronycine (3) afforded 2-nitroacronycine (2) and 2-nitro-6-demethoxyacronycine (4), respectively. Reduction of 2-nitroacronycine yielded, depending on the conditions, 2-nitro-1,2-dihydroacronycine (5), 2-oxo-1,2-dihydroacronycine oxime (7) or 2-amino-1,2-dihydroacronycine (6). This latter was readily converted into 2-dimethylamino-1,2-dihydroacronycine (8)
硝化丙烯醛(1)和6-去甲氧基精氨酸(3)分别得到2-硝基丙氨酸(2)和2-硝基-6-脱甲氧基丙氨酸(4)。根据条件的不同,还原2-硝基阿卡西霉素产生2-硝基-1,2-二氢阿卡霉素(5),2-氧-1,2-二氢阿卡霉素肟(7)或2-氨基1,2-二氢阿卡霉素(6) )。后者很容易转化为2-二甲基氨基-1,2-二氢加速胺(8),2-乙酰氨基-1,2-二氢加速胺(9)和2-苯甲酰基氨基-1,2-二氢加速胺(10)。评估了这些化合物对L1210白血病细胞的细胞毒性。化合物2和7在抑制L1210细胞增殖方面分别比丙烯醛高300倍和10倍。化合物2没有针对P388白血病和C38结肠腺癌的抗肿瘤活性。
