Synthesis of New Pyrroles of Potential Anti‐Inflammatory Activity

We herein disclose a series of novel pyrrole derivatives 1-4 and pyrrolo[2,3-d]pyrimidine derivatives 6-11 as novel potent anti-inflammatory compounds. The structures were confirmed by IR, (1) H-NMR, and MS. Some newly synthesized compounds were examined for their in-vivo anti-inflammatory activity. Several derivatives showed a promising anti-inflammatory activity compared to ibuprofen. In this paper, we examine and discuss the structure-activity relationships and anti-inflammatory activities of these compounds.
