  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.

  rocaglate (flavagline) natural product, aglaroxin C displays intriguing biological activity by inhibiting hepatitis C viral entry. To further elucidate structure-activity relationships and diversify the pyrimidinone scaffold, we report a concise synthesis of aglaroxin C utilizing a highly regioselective pyrimidinone condensation. We have prepared more than 40 aglaroxin C analogues utilizing various amidine

  作为一种独特的 rocaglate (flavagline) 天然产物，aglaroxin C 通过抑制丙型肝炎病毒进入显示出有趣的生物活性。为了进一步阐明构效关系并使嘧啶酮支架多样化，我们报告了利用高度区域选择性嘧啶酮缩合的 aglaroxin C 的简明合成。我们已经利用各种脒缩合伙伴制备了 40 多种 aglaroxin C 类似物。通过对类似物的生物学评估，我们发现了两种先导化合物 CMLD012043 和 CMLD012044，它们显示出对丙型肝炎病毒进入抑制与翻译抑制的优先偏向。总体而言，该研究证明了化学合成能够产生具有靶向抑制偏向性和改善的治疗指数的天然产物变体。
