Products Description of Ganciclovir sodium CAS#107910-75-8Ganciclovir sodium is an analog of 2′-deoxyguanine nucleotide that can inhibit the replication of herpes viruses. Its mechanism of action is: ganciclovir is first phosphorylated into monophosphate by a protein kinase homolog encoded by CMV (UL97 gene), and then further phosphorylated into diphosphate and triphosphate by cellular kinases. In CMV-infected cells, the level of triphosphate is 100 times higher than that in non-infected cells, indicating that this product can be preferentially phosphorylated in infected cells.
