Novel analogs of (9R)-9-deoxo-9-(N, N-dimethylamino)erythromycin A bearing N-alkylamino substituents at the C-21 position were synthesized. These compounds retained antibacterial activity. The C-21 N, N-dimethylamino analog showed a modest improvement in activity against some Gram-negative bacteria.
