amino-1,4-oxazine derived BACE-1 inhibitors were explored and various synthetic routes developed. The binding mode of the inhibitors was elucidated by co-crystallization of 4 with BACE-1 and X-ray analysis. Subsequent optimization led to inhibitors with low double digit nanomolar activity in a biochemical and single digit nanomolar potency in a cellular assays. To assess the inhibitors for their permeation
探索了新的氨基-1,4-恶嗪衍生的BACE-1抑制剂,并开发了各种合成途径。通过与BACE-1共同结晶4和X射线分析,阐明了抑制剂的结合方式。随后的优化导致在生化反应中抑制剂具有较低的两位数纳摩尔活性,而在细胞测定法中则只有一位数纳摩尔的效价。为了评估抑制剂的渗透性能和穿越血脑屏障的潜力,成功应用了MDR1-MDCK细胞模型。化合物8a通过在急性治疗方案中剂量依赖性地降低小鼠中的Aβ水平来证实体外结果。
