Linker cleavage
NettetCleavage of acyl hydrazone linker releases doxorubicin (Pharmaceuticals 2024, 14: 442). Hydrazone linkers display a pH-dependent stability, being stable at neutral pH (blood stream) and being hydrolized in acidic media (pH 6 for endosomes then pH 5 for lysosome) to form the corresponding ketone and hydrazine. Nettet8. mai 2024 · Such in vivo cleavable linkers are designed to incorporate specific protease-sensitive sequences. Unlike the reduction of disulfide bonds which happens rapidly in the blood circulation (3), the specificity of many proteases offers slower cleavage of the linker in constrained compartments.

Nettet10. apr. 2024 · Of the four commonly used 2A peptides (P2A, T2A, E2A and F2A), P2A is shown to generally have the highest cleavage efficiency (close to 100% in some cases). T2A comes next, followed by E2A and F2A. The cleavage efficiency of F2A is only about 50%. We generally recommend using P2A or T2A in polycistrons. References
