The CXC chemokine CXCL8/IL-8 plays a major role in the activation and recruitment of polymorphonuclear (PMN) cells at inflammatory sites. CXCL8 activates PMNs by binding the seven-transmembrane (7-TM) G-protein-coupled receptors CXC chemokine receptor 1 (CXCR1) and CXC chemokine receptor 2 (CXCR2). (R)-Ketoprofen (1) was previously reported to be a potent and specific noncompetitive inhibitor of CXCL8-induced human PMNS chemotaxis. We report here molecular modeling studies showing a putative interaction site of 1 in the TM region of CXCR1. The binding model was confirmed by alanine scanning mutagenesis and photoaffinity labeling experiments. The molecular model driven medicinal chemistry optimization of 1 led to a new class of potent and specific inhibitors of CXCL8 biological activity. Among these, repertaxin (13) was selected as a clinical candidate drug for prevention of post-ischemia reperfusion injury.

Abstract A set of new metal coordination polymers constructed from a novel semi-rigid aromaticcarboxylateligand, namely, [M(L)(4PBI)(H2O)]n (M = Ni, Co and Cu for 1, 2 and 3, respectively) and [Cd(L)(4PBI)]n (4) (H2L = 3-(1-carboxyethyl) benzoic acid; 4PBI = 2-(pyridin-4-yl)-(1H)-benzoimidazole), have been synthesized by the hydrothermal reaction, which were characterized by element analyses, FT-IR
