Structure-activity relationship and liver microsome stability studies of pyrrole necroptosis inhibitors.
Necroptosis is a regulated caspase-independent cell death pathway resulting in morphology reminiscent of passive non-regulated necrosis. Several diverse structure classes of necroptosis inhibitors have been reported to date, including a series of [1,2,3]thiadiazole benzylamide derivatives. However, initial evaluation of mouse liver microsome stability indicated that this series of compounds was rapidly degraded. A structure-activity relationship (SAR) study of the [1,2,3]thiadiazole benzylamide series revealed that increased mouse liver microsome stability and increased necroptosis inhibitory activity could be accomplished by replacement of the 4-cyclopropyl-[1,2,3]thiadiazole with a 5-cyano-1-methylpyrrole. In addition, the SAR and the cellular activity profiles, utilizing different cell types and necroptosis-inducing stimuli, of representative [1,2,3]thiadiazole and pyrrole derivatives were very similar suggesting that the two compound series inhibit necroptosis in the same manner.
