Fragment-Based Identification of Amides Derived from trans-2-(Pyridin-3-yl)cyclopropanecarboxylic Acid as Potent Inhibitors of Human Nicotinamide Phosphoribosyltransferase (NAMPT)
摘要:
Potent, trans-2-(pyridin-3-yl)cyclopropane-carboxamide-containing inhibitors of the human nicotinamide phosphoribosyltransferase (NAMPT) enzyme were identified using fragment-based screening and structure-based design techniques. Multiple crystal structures were obtained of initial fragment leads, and this structural information was utilized to improve the biochemical and cell-based potency of the associated molecules. Many of the optimized compounds exhibited nanomolar antiproliferative activities against human tumor lines in in vitro cell culture experiments. In a key example, a fragment lead (13, K-D = 51 mu M) was elaborated into a potent NAMPT inhibitor (39, NAMPT IC50 = 0.0051 mu M, A2780 cell culture IC50 = 0.000 49 mu M) which demonstrated encouraging in vivo efficacy in an HT-1080 mouse xenograft tumor model.
