Zheng X, Hodgetts KJ, Brielmann H, Hutchison A, Burkamp F, Brian Jones A, Blurton P, Clarkson R, Chandrasekhar J, Bakthavatchalam R, De Lombaert S, Crandall M, Cortright D, Blum CA: From arylureas to biarylamides to aminoquinazolines: discovery of a novel, potent TRPV1 antagonist. Bioorg Med Chem Lett. 2006 Oct 1;16(19):5217-21. Epub 2006 Jul 25.
Bioisosteric replacement of piperazine with an aryl ring in lead VR1 antagonist 1 led to the biarylamide series. The development of B-ring SAR led to the conformationally constrained analog 70. The resulting aminoquinazoline 70 represents a novel VR1 antagonist with improved in vitro potency and oral bioavailability vs the analogous compounds from the lead series. |
