We herein disclose a series of novel pyrrole derivatives as well as fused pyrrolopyridines 6a,b and 7a,b, pyrrolopyrazoles 8a, b, pyrrolo[2,3-d]pyrimidine derivatives 10a-d, 12a,b, 14a,b, 18a,b, 20a,b, 21a,b, 22a,b, 23a,b, 24a,b, 31a,b, 36a,b, 40a,b, pyrrolo[1,2,6]thiadiazine derivatives 19a,b, pyrrolotriazolopyrimidines 25a,b, 26a,b, 27a,b and 28a,b, pyrrolo[2,3-d][1,2,3]triazine derivatives 32a,b and pyrrolo[2,3-d][1,3]oxazine derivatives 39a,b as novel compounds. All compounds were evaluated for their anti-inflammatory, analgesic (compared to the reference drug Indomethacin) and antimicrobial activities (compared to the reference drug Ampicillin and Fluconazole). Compounds 4d, 5b-d, 6a,b, 9c,d, 10d, 12ab, 13b, 19a,b, 21b, 23b, 31a,b, 38b and 40a were found to be the most active anti-inflammatory drugs exhibiting potency ranging from 1 - 1.01 compared to the reference drug indomethacin. In addition to docking study of these highly active twenty compounds against the active site of cyclooxygenase-2 enzyme (COX-2), among the tested compounds, compounds 5d, 9d, 11b, 12a, 13b and 32a showed multiple activities; anti-inflammatory, analgesic and anti-bacterial activities.
