Design, synthesis, and biological evaluation of novel coxsackievirus B3 inhibitors

The synthesis and SAR study of a novel class of coxsackievirus B3 (CVB3) inhibitors are reported. These compounds could be considered as the 6-chloropurines substituted at position 9 with variously substituted bicyclic scaffolds (bicyclo[2.2.1]heptane/ene—norbornane or norbornene). The synthesis and biological evaluation of 31 target compounds are described. Several of the analogues inhibited CVB3 in the low micromolar range (0.66–2 μM). Minimal or no cytotoxicity was observed.

We report synthesis and results of the anti-coxsackievirus B3 screening of the novel 6-chloropurine derivatives.Figure optionsDownload as PowerPoint slide
