摘要
Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive and lethal malignancy with extremely poor patient survival rates. A key reason for the poor prognosis is the lack of effective diagnostic tools to detect the disease at curable, premetastatic stages. Tumor surgical resection is PDAC first‐line treatment, however distinguishing between cancerous and healthy tissue with current imaging tools remains a challenge. In this work, we report a DOTA‐based fluorescent probe targeting plectin‐1 for imaging PDAC with high specificity. To enable heterogeneous functionalization of the DOTA‐core with multiple targeting peptide units and the fluorophore, a novel, fully clickable synthetic route that proceeds in one‐pot was developed. Extensive validation of the probe set the stage for PDAC detection in mice and human tissue. Altogether, these findings may pave the way for improved clinical understanding and early detection of PDAC progression as well as more accurate resection criteria.
