Aminopeptidases are a group of enzymatic proteins crucial for protein digestion, catalyzing the cleavage of amino acids at the N-terminus of peptides. Among them are (coding for endoplasmic reticulum aminopeptidase 1), (coding for endoplasmic reticulum aminopeptidase 2), and (coding for leucyl and cystinyl aminopeptidase). These genes encoding these enzymes are contiguous and located on the same chromosome (5q21); they share structural homology and functions and are associated with immune-mediated diseases.

Kirsten rat sarcoma (KRAS) is the most frequently mutated oncogene in colorectal cancer, being present in 30% of patients with localized disease and in almost half of the patients that develop metastatic disease. While the development of chemotherapy doublets and targeted therapy have improved survival in recent years, KRAS mutation still has a controversial role regarding its prognostic and predictive value both in the adjuvant and in the metastatic setting. The impact of KRAS mutation on treatment strategy remains to be better defined.

Despite the presence of a variety of modern anticancer drugs at the market, doxorubicin (Dox) is still widely used in antineoplastic therapy, although its administration causes severe side effects. To enhance specific activity of such molecules, various approaches have been exploited: targeted moieties like monoclonal antibodies, onco-specific proteins and peptides are utilized as specific vector molecules; environment sensitive linkers are exploited to facilitate transported drug release at the target point etc. Acid-labile linkers are frequently used in synthesis due to the ability to be cleaved inside specific cellular compartments with acidic environment, avoiding possible recycling mechanisms.
