  Efficient synthesis of 3 H ,3′ H -spiro[benzofuran-2,1′-isobenzofuran]-3,3′-dione as novel skeletons specifically for influenza virus type B inhibition

  摘要：

  An efficient and novel two step synthetic procedure to prepare various substituted 3H,3'H-spiro[benzofuran-2,1'-isobenzofuran]-3,3'-diones A, was established from very simple and easily available starting materials. The developed method is a robust and general approach for the synthesis of these structures. The prepared compounds were tested against influenza virus type A viz., A/Taiwan/1/86 (H1N1), A/Hong Kong/8/68 (H3N2) and type B viz., B/Panama/45/90, B/Taiwan/2/62, B/Lee/40, B/Brisbane/60/2008. Among 31 compounds tested, some of them showed good activity (selective index values >10) against these influenza viruses preferentially for type B. The most active compound 3b showed activity in 3.0-16.1 mu M range with a selectivity index value between 30 and 166 against these type B viruses, in which it was comparable to the antiviral agent favipiravir. Also, 3b is found to be inactive against other enveloped viruses (viz., HIV and HSV) showing its specificity for influenza viruses. (C) 2013 Elsevier Masson SAS. All rights reserved.
