  Design, synthesis and SAR study of hydroxychalcone inhibitors of human β-secretase (BACE1)

  摘要：

  According to the structural characteristics of isoliquiritigenin from Glycyrrhiza uralensis, a series of hydroxychalcones has been designed, synthesized and evaluated for their in vitro inhibitory activities of beta-secretase (BACE1). Structure-activity relationship study suggested that inhibitory activity against BACE1 was governed to a greater extent by the hydroxyl substituent on A- and B-ring of the chalcone, and the most active compound was substituted with four hydroxyl group (17, IC(50) = 0.27 mu M).

  A Prins bicyclization strategy for the stereoselective synthesis of trans-fused hexahydropyrano[3,4-c]chromene derivatives in good to excellent yields has been developed. The synthetic versatility of this approach has been demonstrated in the synthesis of calyxin I and J analogues. This is the first example of the synthesis of hexahydropyrano[3,4-c]chromene derivatives from (E)-3-[2-(benzyloxy)phe

  已经开发了一种用于立体选择性合成反式稠合六氢吡喃并 [3,4-c] 色烯衍生物的 Prins 双环化策略，收率很好。这种方法的合成多功能性已在花萼 I 和 J 类似物的合成中得到证明。这是从 (E)-3-[2-(苄氧基)苯基]-5-苯基戊-4-en-1-醇 (4b) 和醛类。
