  Design and synthesis of highly selective, orally active Polo-like kinase-2 (Plk-2) inhibitors

  摘要：

  Polo-like kinase-2 (Plk-2) is a potential therapeutic target for Parkinson's disease and this Letter describes the SAR of a series of dihydropteridinone based Plk-2 inhibitors. By optimizing both the N-8 substituent and the biaryl region of the inhibitors we obtained single digit nanomolar compounds such as 37 with excellent selectivity for Plk-2 over Plk-1. When dosed orally in rats, compound 37 demonstrated a 41-45% reduction of pS129-alpha-synuclein levels in the cerebral cortex. (C) 2013 Elsevier Ltd. All rights reserved.

  involved in the phosphorylation of α‐synuclein in Lewy bodies, which are one of the hallmarks of Parkinson’s disease neuropathology. Potent, selective, brain‐penetrant inhibitors of Plk‐2 were obtained from a structure‐guided drug discovery approach driven by the first reported Plk‐2–inhibitor complexes. The best of these compounds showed excellent isoform and kinome‐wide selectivity, with physicochemical

  Polo-like kinase-2（Plk-2）被认为是路易体中α-突触核蛋白磷酸化的主要激酶，这是帕金森氏病神经病理学的标志之一。有效的，选择性的，脑渗透性的Plk-2抑制剂是从第一个报道的Plk-2抑制剂复合物驱动的结构指导药物发现方法获得的。这些化合物中最好的化合物表现出出色的同工型和全基因组选择性，其理化特性足以证实体内Plk-2抑制作用。一种这样的化合物在口服后可显着降低大鼠脑内α-突触核蛋白的磷酸化，并为该治疗途径对帕金森氏病的潜在治疗的未来研究提供了有用的探针。
