A series of novel 3‐methyl‐N"‐(2‐oxoindolin‐3‐ylidene)‐4H‐benzo[b][1,4]thiazine‐2‐carbohyrazides have been synthesized and studied on their in vitro antimicrobial activity potency to establish structure‐activity relationship. Several compounds demonstrated promising antifungal and antibacterial activity; however, other tested compounds exhibited moderate to poor antimicrobial activity with respect to the reference drug against the test strains. 相似文献
