Streptozocin is a chemotherapy drug that seeks out pancreatic islet cells, approved in 1982 for the rare tumours that arise from them; the same selectivity makes it the standard way to induce diabetes in laboratory animals.
Streptozocin, an antibiotic from Streptomyces achromogenes, carries a glucose group that lets islet cells take it up through GLUT2. The FDA approved it in 1982 for metastatic islet cell carcinoma of the pancreas, where it produced responses alone and with fluorouracil or doxorubicin in the Eastern Cooperative Oncology Group trials of the 1980s. Kidney toxicity is dose-limiting and nausea is severe. Streptozocin-based chemotherapy remains a guideline option for progressive pancreatic neuroendocrine tumours, though capecitabine with temozolomide and the targeted drugs everolimus and sunitinib are used more often, and it is the standard tool for creating diabetic animal models.
A glucose-linked nitrosourea taken up by the GLUT2 transporter, which is why it homes to pancreatic islet cells; it methylates DNA and depletes NAD, killing the cells.
