As a part of our program to compose multicomponent hybrid templates with potential pharmaceutical recognition, we have designed a library of acetylinic isatin hydrazones ( 1 b‐1 p ) and acetylinic spiroisatins ( 1 q‐1 s ). All the synthesized motifs were thoroughly characterized and then evaluated for their antimicrobial activities followed by cytotoxic appraisal of the more potent compounds in Hek293 and HeLa human cancer cell lines. Computer aided drug design filtered the compounds considered unsuitable for screening purposes. Acetylinic isatin 1 e was the most potent antibacterial scaffold with IC 50 ≈ 1.95 μM against E. coli while 1 n with bis‐isatin assembly was the lead compound against C. albicans with IC 50 ≈ 15.67 μM. SAR allowed to have a thorough anticipation of the substituent effect on the observed bioactivities of the compounds. Further, docking studies of the selected scaffolds on admissible bacterial and fungal proteins elicited isatin 1 a to exhibit highest ligand efficiency. Molecular interactions disclosed that 3’N substituted isatin derivatives may be considered ==as efficient candidates to curb bacterial and fungal diseases.
