描述 | Ganciclovir, a guanosine nucleoside analogue, is a well established broad-spectrum antiviral agent that inhibits replication of viral DNA and is active against both HSV-1 and -2 and several other viruses. Ganciclovir ophthalmic gel 0.15% is a five-times-daily topical preparation that is indicated for the treatment of acute herpetic keratitis (dendritic ulcers). Ganciclovir ophthalmic gel 0.15% was generally well tolerated and was associated with a significantly lower incidence of visual disturbances than aciclovir ointment 3% in the phase III trial[3]. TFT (trifluorothymidine) and GCV (Ganciclovir) are synergistic against acyclovir-susceptible HSV-1 at concentrations significantly less toxic than if each antiviral were used as a sole agent[4]. GCV is used as an antiviral drug, and the thymidine kinase, HSV‑TK can phosphorylate GCV to GCV‑TP, a competitive inhibitor of DNA synthesis, instead of guanine‑5'‑triphosphate in the process of DNA synthesis. HSV‑TK/GCV (Herpes simplex virus type 1 thymidine kinase/ganciclovir) can significantly cause the death of retinoblastoma cell lines, HXO‑RB44 and Y79[5]. When HSV-Tk(+) T cells are added to T cell-depleted BM a consequently developing GVH can be controlled by GCV treatment with 60-70% of the animals surviving[6]. Moreover, long-circulating liposome-encapsulated GCV is a new approach to drug carriers to enhance the efficacy of suicide gene therapy[7]. |
