18-amino-4''-O-benzoyl-4'''-N-demethyl-18-deoxospiramycins were designed and synthesized. Synthetic strategy involved selective demethylation of the dimethylamino group in forosamine, benzoylation of the hydroxyl group at the C4'' position and reductive N-amination of the formyl group. Antibacterial characteristics of spiramycin derivatives were tested. The derivatives exhibited promising activity against drug-resistant bacterial strains.
设计并合成了18-氨基-4''-O-苯甲酰基-4'''-N-去甲基-18-脱氧螺旋霉素。合成策略包括福洛糖胺中二甲氨基的选择性脱甲基、C4''位羟基的苯甲酰化以及甲酰基的还原N-胺化。测试了螺旋霉素衍生物的抗菌特性。这些衍生物对耐药菌株表现出有前景的活性。
