9-subsituted-N-(2-chlorobenzyl)purine-6-amine derivative, as well as preparation method and application thereof

The invention discloses a 9-subsituted-N-(2-chlorobenzyl)purine-6-amine derivative. The structure of the derivative is shown in a formula (I), where R is selected from a hydrogen atom, a C1-C4 alkyl group and a substituted or unsubstituted benzyl group, and a substituent on the benzyl group is one or more independently selected from halogen, -CF3, a C1-C4 alkoxy group, a C1-C4 alkyl group and a nitro group; R4 is a substituted or unsubstituted phenyl group or benzyl group, and a substituent on the phenyl group or the benzyl group is one or more of halogen and a methoxy group. Compared with a 6-benyl adenine compound complex gold ion (inhibitor 3), the 9-subsituted-N-(2-chlorobenzyl)purine-6-amine derivative is proved by testing results to have the advantages of higher inflammation factor inhibition rate, higher anti-inflammation activity and potential for use as an anti-inflammation medicament. (The formula (I) is shown in the description.).
