Synthesis and anti-integrase evaluation of novel calix[4]arene derivatives containing the triazolyl 1,3-diketo moiety
摘要:
A series of novel calix[4]arene derivatives incorporating two triazolyl 1,3-diketo subunits in alternate positions at the lower rim were synthesized and screened for HIV integrase inhibition activity. The chemical structures of these compounds were confirmed by means of H-1 NMR, C-13 NMR, and ESI-MS. Preliminary bioassays indicated that calix[4]arene derivatives proved to be more active than p-tert-butylcalix[4]arene derivatives. In particular, compound 4g presented the most potent integrase strand transfer inhibitory activity with an IC50 value of 6.1 mu mol/L. (C) 2014 Zai-Gang Luo and Xue-Mei Xu.
