Development of Orally Bioavailable and CNS Penetrant Biphenylaminocyclopropane Carboxamide Bradykinin B1 Receptor Antagonists
摘要:
A series of biphenylaminocyclopropane carboxamide based bradykinin B-1 receptor antagonists has been developed that possesses good pharmacokinetic properties and is CNS penetrant. Discovery that the replacement of the trifluoropropionamide in the lead structure with polyhaloacetamides, particularly a trifluoroacetamide, significantly reduced P-glycoprotein mediated efflux for the series proved essential. One of these novel bradykinin B-1 antagonists (13b) also exhibited suitable pharmacokinetic properties and efficient ex vivo receptor occupancy for further development as a novel approach for the treatment of pain and inflammation.
Substituted biaryl-carboyxlate derivatives are bradykinin B1 antagonists or inverse agonists useful in the treatment or prevention of symptoms such as pain and inflammation associated with the bradykinin B1 pathway.

cross-coupling reaction of phenols and primary amines using a simple and readily available multifunctional reagent. The reactions work by induced proximity and electronic activation of both the nucleophile and the electrophile for net dehydrative C–N coupling reactions. Notably, the reactions do not involve the use of a transition metal for C–N bond formation, preactivation of the phenol electrophile, or exclusion
