N-Formyl peptide receptors (FPRs) are G protein-coupled receptors (GPCRs) that play critical roles in inflammatory reactions, and FPR-specific interactions can possibly be used to facilitate the resolution of pathological inflammatory reactions. We here report the synthesis and biological evaluation of six pairs of chiral ureidopropanamido derivatives as potent and selective formyl peptide receptor-2 (FPR2) agonists that were designed starting from our lead agonist (S)-3-(1H-indol-3-yl)-2-[3-(4-methoxyphenyl)ureido]-N-[[1-(5-methoxy-2-pyridinyl)cyclohexyl]methyl]propanamide ((S)-9a). The new compounds were obtained in overall yields considerably higher than (S)-9a. Several of the new compounds showed agonist properties comparable to that of (S)-9a along with higher selectivity over FPR1. Molecular modeling was used to define chiral recognition by FPR2. In vitro metabolic stability of selected compounds was also assessed to obtain preliminary insight on drug-like properties of this class of compounds.

Preparation and antioxidant activity of α-pyridoin and its derivatives

Focusing on α-pyridoin (1, 1,2-di(2-pyridyl)-1,2-ethenediol) as the lead compound of the novel antioxidative enediol, we synthesized 5,5′- or 6,6′-bis-substituted derivatives of 1 from disubstituted pyridines. The antioxidant activity of 1 and its synthetic derivatives 2-7 was evaluated by DPPH (1,1-diphenyl-2-picrylhydrazyl radical) scavenging assay and inhibition of lipid peroxidation. In the DPPH assay, 1 exhibited an activity stronger than that of ascorbic acid, and 5,5′-dimethyl-(5) or 5,5′-dimethoxy- substituted derivatives (6) exhibited more potent activity than 1. The DPPH scavenging activities of α-pyridoins were correlated with their oxidation potential and thus the electron density of enediol. 5 and 6 effectively inhibited lipid peroxidation in the rat liver microsome/tert-butyl hydroperoxide system. Therefore, 5 and 6 serve as good candidates for a pharmacologically useful enediol antioxidant.
Non-peptide bombesin receptor antagonists

, (2008/06/13)
The compounds of the instant invention are novel compounds of Formula I or a pharmaceutically acceptable salt thereof wherein Ar is phenyl or pyridyl unsubstituted or substituted. Ar1can be independently selected from Ar and can also include pyridyl-N-oxide, indolyl, imidazole, and pyridyl; R3can be independently selected from Ar or is hydrogen, hydroxy, NMe2, N-methyl-pyrrole, imidazole, tetrazole, thiazole (a), (b), (c), or (d), wherein Ar2is phenyl or pyridyl. The instant compounds antagonize the bombesin receptors in mammals and are therefore effective in treating and/or preventing depression, psychoses, seasonal affective disorders, cancer, feeding disorders, gastrointestinal disorders, inflammatory bowel disease, sleep disorders, and memory impairment.

2--1H-thienoimidazoles. A Novel Class of Gastric H+/K+-ATPase Inhibitors
Weidmann, Klaus,Herling, Andreas W.,Lang, Hans-Jochen,Scheunemann, Karl-Heinz,Rippel, Robert,et al.
, p. 438 - 450 (2007/10/02)
2-thienoimidazoles were synthesized and investigated as potential inhibitors of gastric H+/K+-ATPase.The isomers of the two possible thienoimidazole series were found to be potent inhibitors of gastric acid secretion in vitro and in vivo.Structure-activity relationships indicate that especially lipophilic alkoxy, benzyloxy, and phenoxy substituents with additional electron-demanding properties in the 4-position of the pyridine moiety combined with an unsubstituted thienoimidazole lead to highly active compounds with a favorable chemical stability.Various substitution patterns in the thienoimidazole moiety result in lower biological activity.The heptafluorobutyloxy derivative saviprazole (HOE 731, 5d) was selected for further development and is currently undergoing clinical evaluation.Comprehensive pharmacological studies indicate a pharmacodynamic profile different to omeprazole, the first H+/K+-ATPase blocker introduced on the market.
