制备方法与用途

用途

2-肼基嘧啶可用作医药合成中间体。

制备

2-肼基嘧啶的制备步骤如下：将2-氯嘧啶（0.70克，6.11毫摩尔）溶解在吡啶（15毫升）中，并加入无水肼（2.5毫升），然后在室温下搅拌5分钟。随后，再加入8毫升吡啶。反应混合物在室温下继续搅拌1.5小时后，进行真空浓缩。将残留物悬浮于4毫升水中，通过抽滤收集所得固体并风干。最终得到的2-肼基嘧啶为无色固体，产率为25%（0.171克）。

  Synthesis and biological evaluation of substituted pyrazoles as blockers of divalent metal transporter 1 (DMT1)

  摘要：

  Three distinct series of substituted pyrazole blockers of divalent metal transporter 1 (DMT1) were elaborated from the high-throughput screening pyrazolone hit 1. Preliminary hit-to-lead efforts revealed a preference for electron-withdrawing substituents in the 4-amido-5-hydroxypyrazole series 6a-l. In turn, this preference was more pronounced in a series of 4-aryl-5-hydroxypyrazoles 8a-j. The representative analogs 6f and 12f were found to be efficacious in a rodent model of acute iron hyperabsorption. These three series represent promising starting points for lead optimization efforts aimed at the discovery of DMT1 blockers as iron overload therapeutics. (C) 2011 Elsevier Ltd.
