a, a-Trehalose derivatives bearing guanidino groups as inhibitors to HIV-1 Tat-TAR RNA interaction in human cells
Bioorganic & Medicinal Chemistry Letters 14 (2004) 2585-2588，-0001，（）：
Replication of HIV-1 requires specific interactions of Tat protein with TAR RNA. Disruption of Tat-TAR RNA interaction could inhibit HIV-1 replication. Here four target compounds were designed and synthesized to bind to TAR RNA for blocking the interaction of Tat-TAR RNA. The core molecule 6,60-diamino-6,60-dideoxy-a,a-trehalose was obtained from selective bromination of, a,a-trehalose at C-6,60, followed by acetylation, azide displacement, deacetylation, and reduction. Coupling of the core molecule with the protected amino acid, then deprotection and guanidinylation generated the novel a,a-trehalose derivatives. Their abilities to inhibit Tat-TAR RNA interaction in human cells were determined by a Tat-dependent HIV-1 LTR-driven CAT assays.
