Thiazolopyridin-2-yloxy-phenyl and thiazolopyrazin-2-yloxy-phenyl amine compounds are described, which are useful as LTA4 hydrolase (LTA4H) modulators. Such compounds may be used in pharmaceutical compositions and methods for modulation of LTA4H and for the treatment of disease states, disorders, and conditions mediated by LTA4 hydrolase activity.
Triazine‐based preorganized tripodal receptors are reported as efficient transmembrane Cl− carriers. These receptors were designed based on triazine core and 3,7‐diazabicyclo[3.3.1]nonane arms to facilitate preorganized cavity formation. Each bicyclic arm was further functionalized to control protonation and lipophilicity, which are crucial for their efficient anion binding and effective transport

3,7-Diazabicyclo[3.3.1]nonane is a naturally occurring scaffold interacting with nicotinic acetylcholine receptors (nAChRs). When one nitrogen of the 3,7-diazabicyclo[3.3.1]nonane scaffold was implemented in a carboxamide motif displaying a hydrogen bond acceptor (HBA) functionality, compounds with higher affinities and subtype selectivity for alpha 4 beta 2* were obtained. The nature of the HBA system (carboxamide, sulfonamide, urea) had a strong impact on nAChR interaction. High affinity ligands for alpha 4 beta 2* possessed small alkyl chains, small un-substituted hetero-aryl groups or para-substituted phenyl ring systems along with a carboxamide group. Electrophysiological responses of selected 3,7-diazabicyclo[3.3.1]nonane derivatives to Xenopus oocytes expressing various nAChR subtypes showed diverse activation profiles. Compounds with strongest agonistic profiles were obtained with small alkyl groups whereas a shift to partial agonism/antagonism was observed for aryl substituents. (C) 2013 Elsevier Ltd.
