Mal-amide-PEG8-Val-Ala-PAB-PNP（Cat No.:I042478）is a prodrug designed for targeted drug delivery and cancer therapy. It features a maleimide (Mal) group for conjugation with targeting molecules, an amide linkage, and a polyethylene glycol (PEG8) spacer to enhance solubility and stability. The peptide linker, Val-Ala, is cleavable by specific enzymes, while the para-aminobenzyl (PAB) group facilitates activation. The para-nitrophenyl (PNP) moiety acts as a leaving group upon enzymatic cleavage, releasing the active drug. This structure improves selective drug delivery to tumor sites, reducing systemic toxicity and enhancing therapeutic efficacy.
