  Discovery of 2-methylpyridine-based biaryl amides as γ-secretase modulators for the treatment of Alzheimer’s disease

  摘要：

  gamma-Secretase modulators (GSMs) are potentially disease-modifying treatments for Alzheimer's disease. They selectively lower pathogenic A beta 42 levels by shifting the enzyme cleavage sites without inhibiting gamma-secretase activity, possibly avoiding known adverse effects observed with complete inhibition of the enzyme complex. A cell-based HTS effort identified the sulfonamide 1 as a GSM lead. Lead optimization studies identified compound 25 with improved cell potency, PKDM properties, and it lowered A beta 42 levels in the cerebrospinal fluid ( CSF) of Sprague-Dawley rats following oral administration. Further optimization of 25 to improve cellular potency is described. (C) 2013 Elsevier Ltd. All rights reserved.

  Exploration of the linkage elements of porcupine antagonists led to potent Wnt signaling pathway inhibitors

  摘要：

  The Wnt signaling pathway is a pivotal developmental pathway. It operates through control of cellular functions such as proliferation, differentiation, migration and polarity. Aberrant Wnt signaling has been implicated in the formation and metastasis of tumors. Porcupine is a component of the Wnt signaling pathway. It is a member of the membrane-bound O-acyltransferase family of proteins. Porcupine catalyzes the palmitoylation of Wnt proteins, a process which is essential to their secretion and activity. Here we report a novel series of compounds obtained by a scaffold hybridization strategy from two known porcupine inhibitor classes. The leading compound 62 demonstrated subnanomolar (IC50 0.11 nM) inhibition of Wnt signaling in a paracrine cellular reporter gene assay. Compound 62 also potently inhibited Wnt secretion into culture medium, an indication of direct inhibition of the porcupine protein. Furthermore, compound 62 showed excellent chemical, plasma and liver microsomal stabilities. Collectively, these results strongly support further optimization of this novel scaffold to develop better Wnt pathway inhibitors. (C) 2015 Elsevier Ltd. All rights reserved.
