background and objective: cytomegalovirus (cmv) infections are associated with severe morbidity and mortality in patients, especially pediatric renal transplantation patients. the use of immunosuppressive agents places these patients at the risk of viral infections. as cytomegalovirus infection influences the graft outcome, adopting useful strategies for limiting this virus after transplantatio...

The efficient syntheses of 5-(2-hydroxyethyl)- and 5-(3-hydroxypropyl)-substituted pyrimidine derivatives bearing 2,3-dihydroxypropyl, acyclovir-, ganciclovir- and penciclovir-like side chains are reported. A synthetic approach that included the alkylation of an N-anionic-5-substituted pyrimidine intermediate (method A) provided the target acyclonucleosides in significantly higher overall yield...

Background: Acyclovir, a specific and selective inhibitor of replication of herpesviridae family, has well documented efficacy for speedy rash healing and decreasing pain of herpes zoster. Limited oral bioavailability of acyclovir requires frequent dosing. Valacyclovir is rapidly and almost completely converted to acyclovir in vivo and gives three to fivefold increase in acyclovir bioavailabili...

  Background :Wide distribution and low half-life of acyclovir has led to a high dose consumption of the drug. Recent studies have shown that encapsulation of acyclovir in nano-carriers can increase effectiveness and decrease its side effects. We investigated the inhibitory effect of acyclovir loaded nano-niosomes against herpes simplex virus type-1 (HSV-1) in cell culture.   Methods : In-vitro...

Background: Acyclovir is asynthetic purin nucleoside analog,which has been reported to be very effective against the treatment of herpes simplex and varicella zoster infections. Acyclovir is known to be toxic to gonads, but available literature fails to provide the indepth analyses of damage.The aim of the present study was to evaluate the effect of Acyclovir on DNA damage and nuclear maturatio...
