dna alkylation

Streptozotocin (Streptozocin, NSC-85998) is an antibiotic that enters pancreatic β-cells via the glucose transporter (GLUT2) and induces DNA methylation, leading to β-cell apoptosis. It is toxic to insulin-producing cells and commonly used to establish diabetic animal models. This product is unstable in solution and is recommended to be prepared freshly before use.

Busulfan is an alkylating antineoplastic agent derived from dimethane sulfonate, with cytotoxic and immunosuppressive properties. It primarily acts by forming carbonium ions in vivo, which induce cross-linking between DNA strands or between DNA and proteins, leading to DNA damage, inhibition of DNA replication, and suppression of RNA transcription. In addition, Busulfan can inhibit thioredoxin reductase and induce apoptosis. It is commonly used as a myeloablative agent in preconditioning regimens for bone marrow transplantation and can also be used to establish anemia models.
