Oximic compounds as potential inhibitors of metacaspase-2 (TbMCA2) of Trypanosoma brucei.

Metacaspases are a distinct class of cysteine proteases predominantly found in plants, fungi, and protozoa, crucial for regulating programmed cell death (PCD). They possess unique structural features and differ markedly from caspases in their activation mechanisms and substrate specificities, with a notable preference for binding basic residues in substrates. In this study, we introduced vanillin-derived oximic compounds to explore their pharmaceutical potential.
