  The discovery of a novel series of glucokinase activators based on a pyrazolopyrimidine scaffold

  摘要：

  Glucokinase is a key enzyme in glucose homeostasis since it phosphorylates glucose to give glucose-6-phosphate, which is the first step in glycolysis. GK activators have been proven to lower blood-glucose, and therefore have potential as treatments for type 2 diabetes. Here the discovery of pyrazolopyrimidine GKAs is reported. An original singleton hit from a high-throughput screen with micromolar levels of potency was optimised to give compounds with nanomolar activities. Key steps in this success were the introduction of an extra side-chain, which increased potency, and changing the linking functionality from a thioether to an ether, which led to improved potency and lipophilic ligand efficiency. This also led to more stable compounds with improved profiles in biological assays. (C) 2012 Elsevier Ltd. All rights reserved.

• Synthesis of 1,4-Disubstituted Pyrazolo[3,4-d]pyrimidines from 4,6-Dichloropyrimidine-5-carboxaldehyde: Insights into Selectivity and Reactivity
  作者：Christie Morrill、Young-Choon Moon、Suresh Babu、Neil Almstead

  DOI：10.1055/s-0033-1338862

  日期：——

  Strategies for carrying out the reaction of 4,6-dichloropyrimidine-5-carboxaldehyde with both aromatic and aliphatic hydrazines to generate 1-substituted 4-chloropyrazolo[3,4-d]pyrimidines in a selective, high-yielding, and operationally simple manner are presented. For aromatic hydrazines, the reaction is performed at a high temperature in the absence of an external base. For aliphatic hydrazines, the reaction proceeds at room temperature in the presence of an external base. The observed selectivity and reactivity trends are rationalized through consideration of the proposed reaction mechanism. The 1-substituted 4-chloropyrazolo[3,4-d]pyrimidine products serve as versatile synthetic intermediates, through further functionalization of the 4-chloride moiety, enabling the rapid generation of a structurally diverse array of 1,4-disubstituted pyrazolo[3,4-d]pyrimidines.
