Kinase domain inhibition of leucine rich repeat kinase 2 (LRRK2) using a [1,2,4]triazolo[4,3-b]pyridazine scaffold
摘要:
Leucine rich repeat kinase 2 (LRRK2) has been genetically linked to Parkinson's disease (PD). The most common mutant, G2019S, increases kinase activity, thus LRRK2 kinase inhibitors are potentially useful in the treatment of PD. We herein disclose the structure, potential ligand-protein binding interactions, and pharmacological profiling of potent and highly selective kinase inhibitors based on a triazolopyridazine chemical scaffold.

Structure-based design of 3-aryl-6-amino-triazolo[4,3-b]pyridazine inhibitors of Pim-1 kinase
摘要:
A series of substituted 3-aryl-6-amino-triazolo[4,3-b]pyridazines were identified as highly selective inhibitors of Pim-1 kinase. Initial exploration identified compound 24 as a potent, selective inhibitor, limited in its utility by poor solubility and permeability. Understanding the unusual ATP-binding site of the Pim kinases and X-ray crystallographic data on compound 24 led to design improvements in this class of inhibitor. This resulted in compound 29, a selective, soluble and permeable inhibitor of Pim-1. (C) 2009 Elsevier Ltd. All rights reserved.

[3-(6-Chloropyridazin-3-yl)-3,4-dihydropyridazino[4,5-b]quinoxalin-2(1H)-yl](phenyl)methanone has been synthesized and its two stable forms were isolated. For the establishment of their structures, B3LYP geometry and energy and GIAO/B3LYP NMR calculations of possible conformers using the polarizable continuum model were performed. The differences in calculated spectra allow attributing calculated structures
合成了[3-(6-氯代哒嗪-3-基)-3,4-二氢哒嗪并[4,5-b]喹喔啉-2(1H)-基](苯基)甲酮,并分离了两种稳定形式。为了建立其结构,进行了B3LYP几何构型和能级的计算,并使用可极化连续体模型对可能的构象体进行了GIAO / B3LYP NMR计算。计算光谱的差异允许通过其1 H和13 C NMR归因于计算结构和获得的物质。构象比与其计算的吉布斯能量相关。
