Elastase is a group of serine proteases that include the macrophage elastase, the fibroblast elastase, the neutrophil elastase, and the pancreatic elastase. Elastase can not only cleave the important connective tissue protein elastin, but also facilitate the degradation of the extracellular matrix such as fibronectin; laminin; collagens III, IV, and VI; and proteoglycans.

Mammalian elastases occur mainly in the pancreas and the phagocytes. Among non-mammalian elastases there is a great variety of bacterial metallo and serine elastases. The elastolytic activity varies from one elastase to another and is usually not correlated with the catalytic efficiency of these proteinases. There is a large number of natural (proteins) and synthetic elastase inhibitors. Elastases play a pathologic role in pulmonary emphysema, cystic fibrosis, infections, inflammation, and atherosclerosis.

    VIP236
    VIP236 is a small-molecule drug conjugate targeting αvβ3 integrin. VIP236 achieves tumor homing via specific binding to αvβ3 integrin and delivers its payload to the tumor microenvironment. The linker of VIP236 is cleavable by neutrophil elastase, which is highly expressed in the tumor microenvironment, to release the payload 7-ethylcamptothecin. This payload induces DNA damage by inhibiting topoisomerase 1, thereby exerting anti-tumor effects. VIP236 exhibits excellent plasma stability and tumor targeting property, with a tumor/plasma payload ratio 10-fold higher than that of the single administration. It effectively induces tumor regression, reduces metastasis formation, and shows good tolerance in mouse models. VIP236 has been used in studies related to non-small cell lung cancer, clear cell renal cell carcinoma, colon cancer, triple-negative breast cancer, small cell lung cancer, and metastatic solid tumors.
