Thiadiazolopiperazinyl ureas as inhibitors of fatty acid amide hydrolase
摘要:
A series of thiadiazolopiperazinyl aryl urea fatty acid amide hydrolase ( FAAH) inhibitors is described. The molecules were found to inhibit the enzyme by acting as mechanism-based substrates, forming a covalent bond with Ser241. SAR and PK properties are presented. (C) 2008 Elsevier Ltd.

Aryl urea derivatives of spiropiperidines as NPY Y5 receptor antagonists
摘要:
Continuing medicinal chemistry studies to identify spiropiperidine-derived NPY Y5 receptor antagonists are described. Aryl urea derivatives of a variety of spiropiperidines were tested for their NPY Y5 receptor binding affinities. Of the spiropiperidines so far examined, spiro[3-oxoisobenzofurane-1(3H),4 '-piperidine] was a useful scaffold for producing orally active NPY Y5 receptor antagonists. Oral administration of 5c significantly inhibited the Y5 agonist-induced food intake in rats with a minimum effective dose of 3 mg/kg. In addition, this compound was efficacious in decreasing body weight in diet-induced obese mice. (C) 2009 Elsevier Ltd. All rights reserved.
