Docking studies of few C-3 Substituted Azapteridines which act as Hepatitis C Virus RNADependent RNA Polymerase inhibitor was performed by using MOE 2009. The docking studies reveal that majority of the Azapteridine derivatives interacted with Hepatitis C Virus RNADependent RNA Polymerase through hydrogen bonding as well as hydrophobic interactions. The present analysis is useful in future drug design.
