  Brain-Penetrant, Orally Bioavailable Microtubule-Stabilizing Small Molecules Are Potential Candidate Therapeutics for Alzheimer’s Disease and Related Tauopathies

  摘要：

  Microtubule (MT) stabilizing drugs hold promise as potential treatments for Alzheimer's disease (AD) and related tauopathies. However, thus far epothilone D has been the only brain-penetrant MT-stabilizer to be evaluated in tau transgenic mice and in AD patients. Furthermore, this natural product exhibits potential deficiencies as a drug candidate, including an intravenous route of administration and the inhibition of the P-glycoprotein (Pgp) transporter. Thus, the identification of alternative CNS-active MT-stabilizing agents that lack these potential limitations is of interest. Toward this objective, we have evaluated representative compounds from known classes of non-naturally occurring MT-stabilizing small molecules. This led to the identification of selected triazolopyrimidines and phenylpyrimidines that are orally bioavailable and brain-penetrant without disruption of Pgp function. Pharmacodynamic studies confirmed that representative compounds from these series enhance MT-stabilization in the brains of wild-type mice. Thus, these classes of MT-stabilizers hold promise for the development of orally active, CNS-directed MT-stabilizing therapies.

  评估微管靶向 1,2,4-三唑并[1,5-a]嘧啶的构效关系确定了神经退行性 Tauopathies 的新候选者

  摘要：

  对 tau 和 Aβ 斑块转基因小鼠模型的研究表明，脑渗透性微管 (MT) 稳定化合物，包括 1,2,4-三唑[1,5- a]嘧啶，有望成为阿尔茨海默病和相关神经退行性 tau 蛋白病的候选治疗方法。三唑并嘧啶已作为抗癌剂进行了研究。然而，这些化合物的抗有丝分裂活性并不总是与细胞中 MTs 的稳定性相关。事实上，我们实验室以前的研究确定了在 C6 上连接的片段在确定三唑并嘧啶是否促进 MT 稳定或相反地破坏细胞中的 MT 完整性方面的关键作用。为了进一步阐明构效关系 (SAR) 并确定神经退行性疾病的潜在改善 MT 稳定候选物，设计、合成和评估了一套全面的 68 种三唑并嘧啶同系物，这些同系物在 C6 和/或 C7 处具有结构修饰。

• Synthesis and SAR of [1,2,4]Triazolo[1,5-<i>a</i>]pyrimidines, a Class of Anticancer Agents with a Unique Mechanism of Tubulin Inhibition

  The synthesis and SAR of a series of triazolopyrimidines as anticancer agents are described. Treatment of 5-chloro-6-(trifluorophenyl)-N-fluoroalkyl [1,2,4]triazolo[1,5-a]pyrimidin-7-amine with an alcohol, a thiol, or an alkylamine provided the corresponding final compounds. A clear SAR requirement has been established for optimal activity. A (1S)-2,2,2-trifluoro-1-methylethylamino group or an achiral 2,2,2-trifluoroethylamino group is required at the 5-position to achieve high potency. On the phenyl ring, both fluoro atoms, at the positions ortho to the triazolopyrimidine core, are needed for optimal activity. At the position para to the triazolopyrimidine core, on the phenyl ring, the best activity is achieved with an oxygen linkage followed by a three-methylene unit, and an alkylamino or a hydroxy group. The mechanism of action for this series of triazolopyrimidines was shown to be unique in that they promoted tubulin polymerization in vitro, but did not bind competitively with paclitaxel.(1) Instead, they inhibit the binding of vincas to tubulin. Selected compounds were studied further, and it was shown that these compounds were able to overcome resistance attributed to several multidrug resistance transporter proteins. Lead compounds were shown to inhibit tumor growth in several nude mouse xenograft models, with high potency and efficacy, when dosed either orally or intravenously.

  Previous studies revealed that examples of the non-naturally occurring microtubule (MT)-stabilizing triazolopyrimidines are both brain penetrant and orally bioavailable, indicating that this class of compounds may be potentially attractive in the development of MT-stabilizing therapies for the central nervous system (CNS). We now report on the pharmacokinetics (PK), pharmacodynamics (PD), and metabolism of a selected triazolopyrimidine congener, (S)-3-(4-(5-chloro-7-((1,1,1-trifluoropropan-2-yl) amino)-[1,2,4]triazolo[ 1,5-a] pyrimidin-6-yl)-3,5-difluorophenoxy)-propan-1-ol (4). These studies revealed that 4 exhibits longer brain than plasma half-life that may be exploited to achieve a selective accumulation of the compound within the CNS. Furthermore, compound metabolism studies suggest that in plasma 4 is rapidly oxidized at the terminal hydroxyl group to form a comparatively inactive carboxylic acid metabolite. Peripheral administration of relatively low doses of 4 to normal mice was found to produce a significant elevation in acetylated a-tubulin, a marker of stable MTs, in the brain. Collectively, these results indicate that 4 may effectively target brain MTs at doses that produce minimal peripheral exposure. (C) 2015 Elsevier Ltd. All rights reserved.
