摘要:
AbstractThere has been much attention to biased ligands of G protein‐coupled receptors (GPCRs) for potential pharmacological benefits. Recently, we reported N‐((6‐chloro‐2'‐methoxy‐[1,1'‐biphenyl]‐3‐yl)methyl)ethanamine 1 as G protein‐biased agonist of 5‐HT7R, which could be used as a chemical probe for the study on treatment discovery of autism spectrum disorder. Herein, we describe the synthesis of derivatives of the compound 1 and their biological evaluations in both G protein and β‐arrestin signaling pathway. Total 16 compounds were synthesized and evaluated, and the compounds 3c, 3f, 3i, and 3p could be called as G protein‐biased agonists like the compound 1. Among the four compounds, the compound 3c was the best in efficacy with an Emax value of 73% and the compound 3f was the most potent agonist with an EC50 value of 0.094 μM.
[Problem]
The present invention provides a compound which is useful as an active ingredient of a pharmaceutical composition, in particular, a pharmaceutical composition for preventing and/or treating VAP-1-related diseases.
[Means for Solution]
The present inventors have conducted intensive studies on a compound having a VAP-1 inhibitory activity, and as a result, they have found that a compound of the present invention or a salt thereof exhibits an excellent VAP-1 inhibitory activity and is useful for preventing and/or treating VAP-1-related diseases, in particular, diabetic nephropathy or diabetic macular edema, thereby completing the present invention. The present invention further relates to a pharmaceutical composition, in particular, a pharmaceutical composition for preventing and/or treating VAP-1-related diseases, which comprises the compound of the present invention or a salt thereof, and an excipient.
A process for producing an enyne derivative, and intermediate, which is useful for preparing compounds showing strong inhibiting activities against squalane.epoxidase of Eumycetes and strong anti-cholesterol activities. The process comprises reacting a compound of the formula: Z--CH.sub.2 --CH.dbd.CH--W [I] wherein W is a halogen atom, and Z is a leaving group, with an amine in the presence of a base, if necessary, to obtain a compound of the formula: ##STR1## then reacting an acetylene derivative to this compound in the presence of a palladium catalyst, to obtain a compound of the formula: ##STR2## and, if necessary, N-alkylating this compound.

Disclosed are compounds of formula (I)-(IV), and pharmaceutically acceptable salts thereof, which are inhibitors of the complement system. Also provided are pharmaceutical compositions comprising such a compound, and methods of using the compounds and compositions in the treatment or prevention of a disease or condition characterized by aberrant complement system activity.
Various derivatives of the tetrahydroisoquinoline core were designed as non-steroidal dual-action inhibitors of steroid sulfatase (STS). Sulfamate derivatives and their corresponding phenol derivatives were both synthesized by parallel solid-phase chemistry. The sulfamate compounds were tested for their ability to inhibit STS activity, whereas the phenol compounds were tested for their ability or non-ability
(E)-N-(3-Chloro-2-propenyl)-N-methyl-1naphthylenemethanamine and (E)-3-chloro-N-(3-chloro-2-propenyl)-N-methylbenzo[b]thiophene-7-methanami ne which are useful as intermediates in the production of enyne compounds which exhibit squalene epoxidase inhibiting activity and anti-Eumycetes activity.
