Zheng Yin,Zheng Yin,Yen Liang Chen,Wouter Schul,Qing Yin Wang,Feng Gu,Jeyaraj Duraiswamy,Ravinder Reddy Kondreddi,Pornwaratt Niyomrattanakit,Suresh B. Lakshminarayana,Anne Goh,Hao Ying Xu,Wei Liu,Boping Liu,Joanne Y.H. Lim,Chuan Young Ng,Min Qing,Chin Chin Lim,Andy Yip,Gang Wang,Wai Ling Chan,Hui Pen Tan,Kai Lin,Bo Zhang,Gang Zou,Kristen A. Bernard,Christine E. Garrett,Karen Beltz,Min Dong,Margaret Weaver,Handan He,Arkadius Pichota,Véronique Dartois,Thomas H. Keller,Pei Yong Shi +34 more
TL;DR: The results have proved the concept that a nucleoside inhibitor could be developed for potential treatment of flavivirus infections and suppressed peak viremia, reduced cytokine elevation, and completely prevented the infected mice from death.
Journal ArticleDOI

Ulf Neumann,Mike Ufer,Laura H. Jacobson,Marie-Laure Rouzade-Dominguez,Gunilla Huledal,Carine Kolly,Rainer Lüönd,Rainer Machauer,Siem Jacob Veenstra,Konstanze Hurth,Heinrich Rueeger,Marina Tintelnot-Blomley,Matthias Staufenbiel,Derya R.

David,Bruno Galli,Rita Ramos,Ana Graf,Cristina Lopez Lopez +31 more
TL;DR: In healthy adults ≥ 60 years old, treatment with CNP520 was safe and well tolerated and resulted in robust and dose‐dependent Aβ reduction in the cerebrospinal fluid, and long‐term, pivotal studies with C NP520 have been initiated in the Generation Program.
Journal ArticleDOI
A novel BACE inhibitor NB-360 shows a superior pharmacological profile and robust reduction of amyloid-β and neuroinflammation in APP transgenic mice
Ulf Neumann,Heinrich Rueeger,Rainer Machauer,Siem Jacob Veenstra,Rainer Martin Lueoend,Marina Tintelnot-Blomley,Grit Laue,Karen Beltz,Barbara Vogg,Peter Schmid,Peter Schmid,Wilfried Frieauff,Derya R. Shimshek,Matthias Staufenbiel,Matthias Staufenbiel,Laura H. Jacobson,Laura H. Jacobson +16 more
TL;DR: In this article, NB-360, a potent and brain penetrable BACE-1 inhibitor can completely block the progression of amyloid-β deposition in the brains of APP transgenic mice, a model for Alzheimer's pathology.
Journal ArticleDOI
Pharmacological BACE1 and BACE2 inhibition induces hair depigmentation by inhibiting PMEL17 processing in mice
Derya R. Shimshek,Laura H. Jacobson,Carine Kolly,Natasa Zamurovic,Kamal Kumar Balavenkatraman,Laurent Morawiec,Robert Kreutzer,Juliane Schelle,Mathias Jucker,Barbara Bertschi,Diethilde Theil,Annabelle Heier,Karine Bigot,Karen Beltz,Rainer Machauer,Irena Brzak,Ludovic Perrot,Ulf Neumann +17 more
TL;DR: BACE2-mediated inhibition of PMEL17 proteolytic processing in vitro in mouse and human melanocytes is confirmed and it is demonstrated that BACE2 as well as additional BACE1 inhibition affects melanosome maturation and induces hair depigmentation in mice.
Journal ArticleDOI
Pharmacological Inhibition of MALT1 Protease Leads to a Progressive IPEX-Like Pathology.
Kea Martin,Ursula Junker,Elaine Tritto,Esther Sutter,Tina Rubic-Schneider,Hannah Morgan,Satoru Niwa,Jianping Li,Achim Schlapbach,Dana B. Walker,Marc Bigaud,Christian Beerli,Amanda Littlewood-Evans,Bettina Rudolph,Marc Laisney,David Ledieu,Karen Beltz,Jean Quancard,Frédéric Bornancin,Natasa Zamurovic Ribrioux,Thomas Calzascia +20 more
TL;DR: The results of a series of toxicology studies in rat and dog species using MLT-943 confirm the therapeutic potential of MALT1 protease inhibitors but highlight the safety risks and challenges to consider before potential application of such inhibitors into the clinic.
