6-(2-Furanyl)-9H-purin-2-amine derivatives as A2A adenosine antagonists
摘要:
Structure-activity relationships have been investigated through substitutions at the 9-position of the 2-amino-6-(2-furanyl) purine (5) to identify novel and selective A(2A) adenosine receptor antagonists. Several potent and selective antagonists were identified. In particular, compounds 20, 25, and 26 show very high affinity with excellent selectivity. (c) 2005 Elsevier Ltd. All rights reserved.

The present invention provides fused aryl and heteroaryl derivatives of Formula I that modulate the activity of phosphoinositide 3-kinases (PI3Ks) and are useful in the treatment of diseases related to the activity of PI3Ks including, for example, inflammatory disorders, immune-based disorders, cancer, and other diseases.
An Efficient Approach to the Synthesis of Nucleosides: Gold(I)-Catalyzed N-Glycosylation of Pyrimidines and Purines with Glycosyl ortho-Alkynyl Benzoates
Persuaded with gold: The title reaction in the presence of [Ph3PAuNTf2] (Tf=trifluoromethanesulfonyl) led conveniently to the corresponding nucleosides with excellent regioselectivity (see scheme). Even purine derivatives underwent this transformation owing to the mild conditions, which enabled the use of protecting groups that would not usually be compatible with N‐glycosylation conditions.
The present invention is directed to a method for production of a 2-amino-6-halogenopurine, a novel synthesis intermediate therefor and a method for production of said synthesis intermediate. The desired 2-amino-6-halogenopurine is an intermediate for the production of compounds useful as antiviral agents, and by using the compound of the present invention as a starting material, the 2-amino-6-halogenopurine can be produced in high yield.
