Cyclopropavir inhibits the normal function of the human cytomegalovirus UL97 kinase
Antimicrob Agents Chemother 2011 Oct;55(10):4682-91.PMID:21788463DOI:10.1128/AAC.00571-11.
Cyclopropavir (CPV) is active against human cytomegalovirus (CMV), as well as both variants of human herpesvirus 6 and human herpesvirus 8. The mechanism of action of CPV against CMV is similar to that of ganciclovir (GCV) in that it is phosphorylated initially by the CMV UL97 kinase, resulting in inhibition of viral DNA synthesis. Resistance to CPV maps to the UL97 kinase but is associated primarily with H520Q mutations and thus retains good antiviral activity against most GCV-resistant isolates. An examination of CMV-infected cultures treated with CPV revealed unusual cell morphology typically associated with the absence of UL97 kinase activity. A surrogate assay for UL97 kinase activity confirmed that CPV inhibited the activity of this enzyme and that its action was similar to the inhibition seen with maribavir (MBV) in this assay. Combination studies using real-time PCR indicated that, like MBV, CPV also antagonized the efficacy of GCV and were consistent with the observed inhibition of the UL97 kinase. Deep sequencing of CPV-resistant laboratory isolates identified a frameshift mutation in UL27, presumably to compensate for a loss of UL97 enzymatic activity. We conclude that the mechanism of action of CPV against CMV is complex and involves both the inhibition of DNA synthesis and the inhibition of the normal activity of the UL97 kinase.
Cyclopropavir susceptibility of cytomegalovirus DNA polymerase mutants selected after antiviral drug exposure
Antimicrob Agents Chemother 2012 Jan;56(1):197-201.PMID:21968367DOI:10.1128/AAC.05559-11.
Human cytomegalovirus (CMV) UL54 DNA polymerase (pol) mutants with known patterns of resistance to current antivirals ganciclovir (GCV), foscarnet (FOS), and cidofovir (CDV) were tested for Cyclopropavir (CPV) susceptibility by a standardized reporter-based yield reduction assay. Exonuclease and A987G (region V) mutations at codons commonly associated with dual GCV-CDV resistance in clinical isolates paradoxically conferred increased CPV susceptibility. Various polymerase catalytic region mutations conferring FOS resistance with variable low-grade GCV and CDV cross-resistance also conferred CPV resistance, with 50% effective concentration (EC(50)) increases of 3- to 13-fold. CPV EC(50) values against several pol mutants were increased about 2-fold by adding UL97 mutation C592G. Propagation of a CMV exonuclease mutant under CPV selected for pol mutations less often than UL97 mutations. In 21 experiments, one instance each of mutations E756D and M844V, which were shown individually to confer 3- to 4-fold increases in CPV EC(50), was detected. Unlike GCV and CDV, exonuclease mutations are not a preferred mechanism of CPV resistance, but mutations in and near pol region III may confer CPV resistance by affecting its recognition as an incoming base for DNA polymerization.
Potency and Stereoselectivity of Cyclopropavir Triphosphate Action on Human Cytomegalovirus DNA Polymerase
Antimicrob Agents Chemother 2016 Jun 20;60(7):4176-82.PMID:27139481DOI:10.1128/AAC.00449-16.
Cyclopropavir (CPV) is a promising antiviral drug against human cytomegalovirus (HCMV). As with ganciclovir (GCV), the current standard for HCMV treatment, activation of CPV requires multiple steps of phosphorylation and is enantioselective. We hypothesized that the resulting CPV triphosphate (CPV-TP) would stereoselectively target HCMV DNA polymerase and terminate DNA synthesis. To test this hypothesis, we synthesized both enantiomers of CPV-TP [(+) and (-)] and investigated their action on HCMV polymerase. Both enantiomers inhibited HCMV polymerase competitively with dGTP, with (+)-CPV-TP exhibiting a more than 20-fold lower apparent Ki than (-)-CPV-TP. Moreover, (+)-CPV-TP was a more potent inhibitor than GCV-TP. (+)-CPV-TP also exhibited substantially lower apparent Km and somewhat higher apparent kcat values than (-)-CPV-TP and GCV-TP for incorporation into DNA by the viral polymerase. As is the case for GCV-TP, both CPV-TP enantiomers behaved as nonobligate chain terminators, with the polymerase terminating DNA synthesis after incorporation of one additional nucleotide. These results elucidate how CPV-TP acts on HCMV DNA polymerase and help explain why CPV is more potent against HCMV replication than GCV.
L-valine ester of Cyclopropavir: a new antiviral prodrug
Antivir Chem Chemother 2009 Sep 25;20(1):37-46.PMID:19794230DOI:10.3851/IMP782.
Background: Following the example of L-valine prodrugs of antiviral nucleoside analogues, L-valine ester of Cyclopropavir (valcyclopropavir) was synthesized. Methods: The known tetrahydropyranylcyclopropavir was transformed to N-(tert-butoxycarbonyl)-L-valine ester, which was deprotected to valcyclopropavir. Results: Stability of valcyclopropavir towards hydrolysis at pH 7.0 roughly corresponded to that of valganciclovir. Valcyclopropavir inhibited replication of human cytomegalovirus (HCMV, Towne and AD169 strains) to approximately the same extent as the parent drug Cyclopropavir. Pharmacokinetic studies in mice established that the oral bioavailability of valcyclopropavir was 95%. Conclusions: The prodrug valcyclopropavir offers some improved therapeutic parameters over the parent compound Cyclopropavir.
Cytomegalovirus UL97 mutations affecting Cyclopropavir and ganciclovir susceptibility
Antimicrob Agents Chemother 2011 Jan;55(1):382-4.PMID:21041510DOI:10.1128/AAC.01259-10.
Among the 7 most common UL97 mutations encountered in ganciclovir-resistant clinical cytomegalovirus isolates, the associated Cyclopropavir cross-resistance varies from insignificant (L595S) to substantial (M460I and H520Q) as determined by recombinant phenotyping. Mutations M460I and H520Q were preferentially selected in vitro under Cyclopropavir and conferred 12- to 20-fold increases in 50% effective concentration (EC(50)) values, while M460V, C592G, A594V, and C603W conferred 3- to 5-fold increases. Uncommon mutations M460T and C603R increased Cyclopropavir EC(50)s by 8- to 10-fold.
