Structure–Activity Relationship of Imidazopyridinium Analogues as Antagonists of Neuropeptide S Receptor
摘要:
The discovery and characterization of a novel chemical series of phosphorothioyl-containing imidazopyridines as potent neuropeptide S receptor antagonists is presented. The synthesis of analogues and their structure-activity relationship with respect to the Gq, Gs, and ERK pathways is detailed. The pharmacokinetics and in vivo efficacy of a potent analogue in a food intake rodent model are also included, underscoring its potential therapeutic value for the treatment of sleep, anxiety, and addiction disorders.
A silver triflate (AgOTf)-mediated oxidative pentafluoroethylation of alcohols and phenols with nucleophilic (pentafluoroethyl)trimethylsilane (TMSCF2CF3) using selectfluor as oxidant under mild reaction conditions was developed. This oxidative coupling protocol utilizes broadly available substrates and easily handled reagents to afford various pentafluoroethyl ethers in moderate to excellent yields

order to elucidate the effect of a phenyl group at a remote position on the reactivity and the course of the reaction. The reactivities varied remarkably with the length of the alkyl chain(n); 2>>3 5>6. The rate enhancement was attributed to anchimeric assistance by a remote phenyl group, and the rate depression to the electron-withdrawing inductive effect of a phenyl group.
