O le tele o analogues guanosine, e pei o le acyclovir (ma lona tu'u gutu valaciclovir), penciclovir (i lona gutu prodrug fomu, famciclovir) ma ganciclovir, e fa'aaogaina lautele mo togafitiga o le herpesvirus [ie herpes simplex virus type 1 (HSV-1), ma le ituaiga. 2 (HSV-2), varicella-zoster virus (VZV) ma/poʻo tagata cytomegalovirus (HCMV)] faʻamaʻi pipisi.I tausaga talu ai nei, ua fausia ai le tele o analogues guanosine fou, e aofia ai le 3-membered cyclopropylmethyl and -methenyl derivatives (A-5021 ma synguanol) ma le 6-membered D- ma L-cyclohexenyl derivatives.O le gaioiga o le acyclic / carbocyclic guanosine analogues ua fuafuaina e faasaga i le tele o fusi o siama, e aofia ai le HSV-1, HSV-2, VZV, HCMV, faʻapea foʻi ma tagata herpesviruses type 6 (HHV-6), ituaiga 7 (HHV- 7) ma le ituaiga 8 (HHV-8), ma le siama o le hepatitis B (HBV).O su'esu'ega fou o le guanosine (ie A-5021 ma le D- ma le L-cyclohexenyl G) na maua e matua malosi lava i na fa'ama'i (HSV-1, HSV-2, VZV) o lo'o fa'aogaina mo se thymidine kinase (TK) patino. o la latou gaioiga fa'ama'i (a itiiti ifo o se vaega) e fa'alagolago i le phosphorylation e le TK e mafua mai i le siama.Faʻailogaina faʻamaʻi faʻamaʻi faʻamaʻi sa maitauina foi i le A-5021 faasaga i le HHV-6 ma le D- ma le L-cyclohexenyl G faasaga i le HCMV ma le HBV.Ole gaioiga fa'ama'i o le acyclic/carbocyclic nucleoside analogues e mafai ona fa'amalosia malosi e le mycophenolic acid, o se fa'alavelave malosi ole inosine 5'-monophosphate (IMP) dehydrogenase.O le carbocyclic guanosine analogues fou (ie A-5021 ma D- ma L-cyclohexenyl G) o loʻo i ai se folafolaga sili, e le gata o ni vailaʻau faʻamaʻi mo le togafitiga o faʻamaʻi pipisi o le herpes, ae faʻapea foʻi ma vailaʻau antitumor mo le tuʻufaʻatasiga o le gene therapy / chemotherapy o le kanesa, pe a fa'apea (vaega o) sela tuma ua fa'aliliuina e le viral (HSV-1, VZV) TK gene.
