| + | Individual roles and overlapping functionalities of 12 human caspases during apoptosis and other cellular processes remain poorly resolved primarily due to a lack of chemical tools. Here we present a new selective caspase-3 inhibitor, termed Ac-ATS010-KE, with rapid and irreversible binding kinetics. Relative to previously designed caspase-3-selective molecules that have tremendously abated inhibitory rates and thus limited use in biological settings, the improved kinetics of Ac-ATS010-KE permits its use in a cell-based capacity. We demonstrate that Ac-ATS010-KE prevents apoptosis with comparable efficacy to the general caspase inhibitor Ac-DEVD-KE and surprisingly does so without side-chain methylation. This observation is in contrast to the well-established peptide modification strategy typically employed for improving cellular permeability. Ac-ATS010-KE protects against extrinsic apoptosis, which demonstrates the utility of a thiophene carboxylate leaving group in biological settings, challenges the requisite neutralization of free carboxylic acids to improve cell permeability, and provides a tool-like compound to interrogate the role of caspase-3 in a variety of cellular processes. | ||
