Broad-spectrum antiviral activity of carbodine, the carbocyclic analogue of cytidine. Biochemical pharmacology, 1990, Jan-15, Volume: 39, Issue:2 Carbocyclic cytidine (C-Cyd) is a broad-spectrum antiviral agent active against DNA viruses [pox (vaccinia)], (+)RNA viruses [toga (Sindbis, Semliki forest), corona], (-)RNA viruses [orthomyxo (influenza), paramyxo (parainfluenza, measles), rhabdo (vesicular stomatitis)] and (+/-)RNA viruses (reo). The target enzyme of C-Cyd is supposed to be CTP synthetase that converts UTP to CTP. In keeping with this assumption are the observations that (i) C-Cyd effects a dose-dependent inhibition of RNA synthesis in both virus-infected and uninfected cells, and (ii) exogenous addition of either Urd or Cyd reverses both the antiviral and cytocidal activity of C-Cyd, whereas addition of dThd or dCyd fails to do so. The selectivity of C-Cyd against Sindbis, vesicular stomatitis and reo virus is markedly increased when C-Cyd is combined with Cyd (10 micrograms/mL). This combination may therefore be worth pursuing as a chemotherapeutic modality for the treatment of virus infections.

Comparative efficacy of broad-spectrum antiviral agents as inhibitors of rotavirus replication in vitro. Antiviral research, 1986, Volume: 6, Issue:1 Several nucleoside analogues which have previously been established as broad-spectrum antiviral agents, i.e. ribavirin, vidarabine, pyrazofurin, tubercidin, carbodine, (S)-9-(2,3-dihydroxypropyl)adenine [(S)-DHPA], carbocyclic 3-deazaadenosine (C-c3 Ado), (RS)-3-adenine-9-yl-2-hydroxypropanoic acid [(RS)-AHPA] isobutyl ester and neplanocin A were compared for their potency and selectivity as inhibitors of human rotavirus (strains Wa, KUN and MO) replication in vitro. As the most efficacious inhibitors emerged (S)-DHPA, C-c3 Ado, (RS)-AHPA isobutyl ester and neplanocin A, with a minimum inhibitory concentration of 60, 1.4, 1.2 and 0.2 micrograms/ml, and a selectivity index of greater than 3, 70, 80 and greater than 20, respectively. As has been postulated for their antiviral action in general, these adenosine analogues probably owe their anti-rotavirus activity to inhibition of S-adenosylhomocysteine hydrolase, a key enzyme in regulating methylations including those that are required for the maturation of viral mRNA.

Antiviral research, 1986, Volume: 6, Issue:1
