摘要

A series of new tert-butyl 2-(substituted benzamido) phenylcarbamate >(4a–>4j) were synthesized by the condensation of tert-butyl 2-amino phenylcarbamate (>3) with various substituted carboxylic acid in the presence of EDCI and HOBt as coupling reagent, obtain in excellent yields. The structures of all newly synthesized compounds were characterized spectroscopically and evaluated for in vivo anti-inflammatory activity compared to the standard drug, indomethacin, by using the carrageenan-induced rat paw edema protocol. Most of the compounds exhibited a promising anti-inflammatory activity within 9 to 12 h, the percentage of inhibition values ranging from 54.239 to 39.021%. The results revealed that the compounds >4i and >4a exhibited better or equivalent anti-inflammatory activity with the percentage of inhibition of 54.239 and 54.130%, respectively, which was comparable to standard drug. In addition to experimental results, in silico docking studies was used as a tool to verify and expand the experimental outcomes.Electronic supplementary materialThe online version of this article (doi:10.1007/s12154-017-0168-x) contains supplementary material, which is available to authorized users.
