Synthesis and evaluation of novel neamine derivatives effectively targeting to RNA
摘要:
Three new derivatives of neamine, 3 (NE), 6 (NEA) and 9 (NEL), were synthesized by connecting arginine or lysine to 5-hydroxyl group of neamine using ethylenediamine as a linker. The binding affinities of these derivatives to A site of 16S RNA and TAR RNA indicate that the modi. cation on 5-hydroxyl of neamine by amino acid can enhance the binding affinity of neamine. Compound 9 (NEL) shows some antibacterial activities. These results demonstrate that modi. cation on 5-hydroxyl group of neamine may provide a promising way for the development of potential candidates effectively targeting to RNAs.

Neamine-heterocycle conjugates as potential anti-HIV agents
摘要:
A series of neamine-heterocycle conjugates were designed and synthesized. All new compounds displayed more potent inhibitory effect on HIV replication than neamine, among them two compounds displayed stronger anti-HIV activity than neomycin B. The results suggested that it might be a promising approach to modify neamine for the discovery of new anti-HIV agents. (C) 2013 Xiao-Lian Zhang, Xin-Shan Ye.
