The invention belongs to the technical field of biological medicines, and particularly discloses a novel application of Epiblastatin A in preparation of a
medicine for relieving
cisplatin-induced
acute kidney injury. The application disclosed by the invention for the first time reveals that by inhibiting the activity of
Casein Kinase 1 (CK1)
kinase, Epiblastine A can obviously relieve renal dysfunction and
kidney tissue structure damage caused by cis-
platinum. Experiments prove that the compound can effectively reduce serum
creatinine and
urea nitrogen levels, significantly improve
renal tubule pathological injury, down-regulate expression of
renal injury early-
stage specific biomarkers KIM-1 and NGAL, and definitely inhibit
renal tubule epithelial
cell apoptosis in an in-vitro model. The invention also provides a specific pharmaceutical composition containing the Epiblastin A and a preparation form of the specific pharmaceutical composition. The invention provides a brand new mechanism and a high-efficiency and low-
toxicity treatment strategy for clinically preventing and treating
cisplatin dosage-limited renal
toxicity, and has important clinical application value.
