Developments in G protein-coupled receptor (GPCR) structural biology provide insights into GPCR-ligand binding. Compound 1 (4-(2-benzylphenoxy)piperidine) with high ligand efficiency for the histamine H1 receptor (H1R) was used to design derivatives to investigate the roles of (i) the amine-binding region, (ii) the upper and lower aromatic region, and (iii) binding site solvation. SAR analysis showed that the amine-binding region serves as the primary binding hot spot, preferably binding small tertiary amines. In silico prediction of water network energetics and mutagenesis studies indicated that the displacement of a water molecule from the amine-binding region is most likely responsible for the increased affinity of the N-methylated analog of 1. Deconstruction of 1 showed that the lower aromatic region serves as a secondary binding hot spot. This study demonstrates that an X-ray structure in combination with tool compounds, assessment of water energetics, and mutagenesis studies enables SAR exploration to map GPCR-ligand binding hot spots.

Ring-closing olefin metathesis (RCM) of 4-methylene-1,7-octadien-3-ones 2, followed by isomerization of the carbon-carbon double bond of 6-methylene-2-cyclohexenones 3 from exo to endo, produced various phenols 4. As an application of the method, the RCM/

Disclosed is a simple method for efficiently and selectively producing a 2-benzylphenol compound. Specifically disclosed is a method for producing a 2-benzylphenol compound represented by the following general formula (2): (wherein R1, R2, R3, R4, R5, R6, R7, R8 and R9 represent the same as defined in the general formula (1) below) which is characterized by reacting a benzylidenecyclohexane compound represented by the following general formula (1): (wherein R1, R2, R3 and R4 may be the same or different and respectively represent a hydrogen atom, an alkyl group or the like; and R5, R6, R7, R8 and R9 may be the same or different and respectively represent a hydrogen atom, an alkyl group or the like) in the presence of a dehydrogenation agent. Consequently, a 2-benzylphenol compound substantially containing no isomers can be produced selectively and efficiently under mild conditions by a simple procedure using an easily-available benzylidenecyclohexane compound as the raw material without requiring a special reaction equipment.
