== Publication Abstract from PubMed ==
 +
To validate the hypothesis that Tyr748 is a crucial residue to aid the discovery of highly selective phosphodiesterase 8A (PDE8A) inhibitors, we identified a series of 2-chloroadenine derivatives based on the hit clofarabine. Structure-based design targeting Tyr748 in PDE8 resulted in the lead compound 3a (IC50 = 0.010 muM) with high selectivity with a reasonable druglike profile. In the X-ray crystal structure, 3a bound to PDE8A with a different mode from 3-isobutyl-1-methylxanthine (a pan-PDE inhibitor) and gave a H-bond of 2.7 A with Tyr748, which possibly interprets the 220-fold selectivity of 3a against PDE2A. Additionally, oral administration of compound 3a achieved remarkable therapeutic effects against vascular dementia (VaD), indicating that PDE8 inhibitors could serve as potential anti-VaD agents.
