6-substituted-9H-purine derivative and preparation method and application thereof
2016
The invention discloses a 6-substituted-9H-purine derivative and a preparation method and application thereof. The derivative has the structure shown as the formula (I). In the formula (I), R is selected from one of pyrrolidiny, furan-2-methyl, benzenesulfonyl, and substituted or unsubstituted phenyl or benzyl, wherein a substituent on phenyl or benzyl is independently selected from one or more of C1-C4 alkoxy, C1-C4 alkyl, hydroxyl, halogen and a group shown in the description, and R4 is independently selected from H or alkyl-substituted benzyl. It is shown in the experimental results that compared with 6-benzyl purine compound complex gold ions (an inhibitor 3), the 6-substituted-9H-purine derivative is higher in inhibition ratio of inflammatory factors and has better anti-inflammatory activity. The 6-substituted-9H-purine derivative has the potential as an anti-inflammatory medicine.
