Synthesis of Some <i>N</i>-[(4-Substituted-1-Piperazinyl)-Oxo(Alkyl and Ethylcarbamoyl)]-3-(2-Thiophenyl)Acrylamides as Non-Steroidal Anti-Allergic and Anti-Inflammatory Agents
《Open Journal of Synthesis Theory and Applications》2013年第2期63-72,共10页Osama I. Abd El-Salam Ahmed M. Shalaby Abdulah A. El-Sawy Soha Elshihaby Mohamed Abdulla 
An interesting approach for the design of anti-allergies is rationally considered. It was proved that current anti-allergic drugs comprise piperazine and acrylic acid segments. In harmony with these findings, new prod...
