Title: Design and SAR of new substituted purines bearing aryl groups at N9 position as HIV-1 Tat-TAR interaction inhibitors.

Authors: Pang R, Zhang C, Yuan D, Yang M.

Abstract: Twenty-four purine derivatives bearing aryl groups at N9 position were designed and synthesized as HIV-1 Tat-TAR interaction inhibitors. All the compounds showed high antiviral activities in inhibiting the formation of SIV-induced syncytium in CEM174 cells. Ten of them with low cytotoxicities were evaluated by Tat dependent HIV-1 LTR-driven CAT gene expression colorimetric enzyme assay in human 293T cells at a concentration of 30 microM, indicating effective inhibitory activities of blocking the Tat-TAR interaction. The aryl groups at N9 position affected the binding affinities between compounds and TAR RNA, showing some specificities of aryl groups to TAR RNA.
