ABSTRACT
Transition metal catalysts (TMCs) mediated bioorthogonal catalysis expand the chemical possibilities within cells. Developing synthetic TMCs tools that emulate the efficiency and specificity of natural metalloenzymes is a rewarding yet challenging endeavor. Here, we highlight the potential of molecularly imprinted enzyme mimics (MIEs) containing a Cu center and specific substrate binding domain, for conducing dimethylpropargyloxycarbonyl (DmProc) cleavage reactions within cells. Our studies reveal that the Cu-MIEs act as highly specific guides, precisely catalyzing target substrates, even in glutathione (GSH)-rich cellular environments. By adapting templates similar to the target substrates, we evolved Cu-MIEs activity to a high level and provided a method to broaden its scope to other unique substrates. This system was applied to a thyroid hormone (T3)-responsive gene switch model, inducing firefly luciferase expression by T3 in cells. This approach verifies that MIEs effectively rescue DmProc-bearing T3 prodrugs and seamlessly integrating themself into cellular biocatalytic networks.
