Description: NB-360 is a potent and brain penetrable BACE-1 inhibitor. NB-360 shows a superior pharmacological profile and robust reduction of amyloid-β and neuroinflammation in APP transgenic mice. NB-360 can completely block the progression of Aβ deposition in the brains of APP transgenic mice, a model for amyloid pathology. NB-360 stopped accumulation of activated inflammatory cells in the brains of APP transgenic mice. Upon chronic treatment of APP transgenic mice, patches of grey hairs appeared.
