MC-VA-PABC-MMAE（Cat No.:I043424）is a peptide-drug conjugate designed for targeted cancer therapy. It consists of a peptide sequence (MC-VA) linked to the cytotoxic agent monomethyl auristatin E (MMAE) via a cleavable p-aminobenzyl carbamate (PABC) linker. The MC-VA peptide selectively binds to specific receptors on cancer cells, facilitating the delivery of MMAE directly to the tumor site. Once inside the cell, the PABC linker is cleaved, releasing MMAE to disrupt microtubule dynamics, causing cell cycle arrest and apoptosis. This targeted approach enhances the therapeutic effect while minimizing off-target toxicity.
