Abstract

Background: Pyruvate dehydrogenase kinases (PDHKs), important metabolic and abnormally expressed enzymes in cancer cells, are promising targets for cancer therapy, especially for non-small-cell lung cancer (NSCLC).

Methods: In this study, a new hit, dichloroacetophenone (DAP) analog 9, was postulated to bind to the PDHK1 allosteric pocket, guided by molecular modeling and kinase biochemical experiments. Based on this binding mode, novel DAP analogs were designed and synthesized to confirm the importance of Phe180, Tyr411, and the hydrophobic core at the bottom of the pocket.

Results: This structure-activity relationship (SAR) study led to the discovery of a novel potent hybrid scaffold, dichloroacetophenone biphenylsulfone ether. Dichloroacetophenone biphenylsulfone ether 31 and 32 inhibited PDHK1 with IC₅₀ values of 86 and 140 nM, respectively.

Conclusion: Compound 32 with acceptable in vitro metabolic stability, predicted drug-likeness properties and ADME/T profiles, showed promising therapeutic efficacy in a lung cancer xenograft mouse model.

新型二氯苯乙酮基 PDHK1 抑制剂作为强效抗癌剂。

背景：丙酮酸脱氢酶激酶（PDHKs）是癌细胞中重要的代谢酶和异常表达的酶，是有希望的癌症治疗靶点，尤其是非小细胞肺癌（NSCLC）：在这项研究中，通过分子建模和激酶生化实验，推测了一种新的靶点--二氯苯乙酮（DAP）类似物 9--与 PDHK1 异构口袋的结合。根据这种结合模式，设计并合成了新型 DAP 类似物，以证实 Phe180、Tyr411 和口袋底部疏水核心的重要性：这项结构-活性关系（SAR）研究发现了一种新型强效混合支架--二氯苯乙酮联苯砜醚。二氯苯乙酮联苯砜醚 31 和 32 可抑制 PDHK1，其 IC50 值分别为 86 和 140 nM：结论：化合物 32 具有可接受的体外代谢稳定性、预测的药物相似性和 ADME/T 特征，在肺癌异种移植小鼠模型中显示出良好的疗效。
