  Anti-tumor pyrimidinylpiperazines bind to the prosurvival Bcl-2 protein family member Bcl-XL

  摘要：

  Overexpression of prosurvival or underexpression of pro-death Bcl-2 family proteins can lead to cancer cell resistance to chemotherapy and radiation treatment. Inhibition of the prosurvival Bcl-2 family proteins has become a strategy for cancer therapy and inhibitors are currently being evaluated in the clinic both as single agents and in combination with established drugs. Here we describe the design, synthesis, and evaluation of pyrimidylpiperazines that were discovered to be inhibitors of the prosurvival Bcl-2 protein family member Bcl-XL. This study identified compound 21 which demonstrated a GI(50) value of 8.4 mu M against A549 lung adenocarcinoma cells and a binding affinity K-i value for Bcl-XL of 127 nM. (C) 2011 Elsevier Ltd.

  黄嘌呤衍生物的最优化可产生作为靶向DPP-IV和GPR119的强效双配体的HBK001盐酸盐。

  摘要：

  通过成环策略发现了一系列源自先前命中的20i的黄嘌呤化合物，它们在末端侧链上进行了修饰。对疏水侧链中带有刚性杂环的化合物的系统优化导致了新的先导化合物HBK001（21h），其具有改进的DPP-IV抑制作用和体外适度的GPR119激动活性。为了进一步研究PK和PD谱图，我们继续以克为单位合成21h及其盐酸盐（22），并通过ADME / T和口服糖耐量试验（OGTT）对ICR小鼠进行了评估。与其游离碱21h相比，化合物22在体内显示出改善的生物利用度和降低血糖的作用，这可能归因于其溶解度和渗透性的改善。对化合物22的初步毒性研究表明，mini-Ames的结果为阴性，小鼠的初步急性毒性LD50高于1.5 g / kg，而对hERG通道的抑制作用中等，IC50为4.9μM，可能是由于其高亲脂性。这些发现对于将来针对更有效，更安全的靶向DPP-IV和GPR119的双配体治疗糖尿病的药物设计将是有用的。
