ABSTRACT
P2Y6 receptor (P2Y6-R) is involved in various physiological and pathophysiological events. With a view to set rules for the design of UDP-based reversible P2Y6-R antagonists as potential drugs, we established structure-activity relationship of UDP analogues, bearing modifications at the uracil ring, ribose moiety, and the phosphate chain. For instance, C5-phenyl- or 3-NMe-uridine-5'-α,ß-methylene-diphosphonate, 16 and 23, or lack of 2'-OH, in 12-15, resulted in loss of both agonist and antagonist activity toward hP2Y6-R. However, uridylyl phosphosulfate, 19, selectively inhibited hP2Y6-R (IC50 112 µM) versus P2Y2/4-Rs. In summary, we have established a comprehensive SAR for hP2Y6-R ligands towards the development of hP2Y6-R antagonists.
