Binding of acetylcholine and quaternary ammonium compounds to a C3-symmetric bowl-shaped tripeptide of 2-(3-aminophenoxy)propanoic acids acting as a ditopic receptor
摘要:
The new tripeptide reported here is composed of (R)-2-(3-aminophenoxy)propionic acid and is a bowl-shaped receptor that simultaneously binds both cations and anions of acetylcholine chloride and benzyltrimethylammonium compounds. An intriguing conformational change of the host was observed in the complexation of the ionic pair, where anion-induced flipping of the amide group on the macrocycle occurred. (C) 2014 Elsevier Ltd.

The present invention provides a compound of a formula (I) wherein the variables are defined herein; to a process for preparing such a compound; and to the use of such a compound in the treatment of a chemokine (such as CCR3) or H1 mediated disease state.
We recently revealed some of the structure–activity relationships of the aromatic ring and chiral center of lactisole. Photoaffinity labeling is one of the common chemical biology methods to elucidate the interaction between bioactive compounds and biomolecules. In this paper, the novel asymmetric synthesis of lactisole derivatives with common photophores (benzophenone, azide and trifluoromethyldiazirine)
