A novel copper-catalyzed, base-free direct thiolation of xanthines and related heterocycles is described, featuring the use of inexpensive Cu(OAc)2·H2O as the catalyst, O2 as a clean and cheap oxidant, and easy-to-handle disulfides as the thiolation reagents. It works well for both aryl and alkyl disulfides. Moreover, the resultant products can be converted into 8-(hetero)aryl- or alkenyl-substituted
Disclosed are a series of hydroxyl purine compounds and the use thereof as PDE2 or TNFα inhibitors, in particular, the compounds as shown in formula (I), or tautomers or pharmaceutically acceptable salts thereof.

New pharmaceutical compounds of general formula (I): F-(X)q where q is an integer from 1 to 5, preferably 1; -F is chosen among drugs described in the text, -X is chosen among 4 groups -M, -T, -V and -Y as described in the text.
The compounds of general formula (I) are nitrate prodrugs which can release nitric oxide in vivo in a controlled and selective way and without hypotensive side effects and for this reason they are useful for the preparation of medicines for prevention and treatment of inflammatory, ischemic, degenerative and proliferative diseases of musculoskeletal, tegumental, respiratory, gastrointestinal, genito-urinary and central nervous systems.
