Indolyl and dihydroindolyl N-glycinamides as potent and in vivo active NPY5 antagonists
摘要:
A novel series of indolyl and dihydroindolyl glycinamides were identified as potent NPY5 antagonists with in vivo activity from screen hit 1. The dihydroindolyl glycinamide 10a significantly inhibits NPY5 agonist induced feeding at a dose of 0.1 mg/kg. The indolyl glycinamide 12c also inhibits NPY5 agonist induced feeding at a dose of 1 mg/kg. Both compounds 10a and 12c represent potential tools for further investigation into the biology of the NPY5 receptor. (C) 2012 Elsevier Ltd. All rights reserved.

these aggressive cancers. Herein, we describe a covalentfragment screen that identified the chloroacetohydrazidescaffold as a covalent UCHL1 inhibitor. Subsequent optimization provided an improved fragment with single-digit micromolar potency against UCHL1 and selectivity over the closely related UCHL3. The molecule demonstrated efficacy in cellular assays of metastasis. Additionally, we report a ligand-bound
