  Bisaryloxime Ethers as Potent Inhibitors of Transthyretin Amyloid Fibril Formation

  摘要：

  Amyloid fibril formation by the plasma protein transthyretin (TTR), requiring rate-limiting tetramer dissociation and monomer misfolding, is implicated in several human diseases. Amyloidogenesis can be inhibited through native state stabilization, mediated by small molecule binding to TTR's primarily unoccupied thyroid hormone binding sites. New native state stabilizers have been discovered herein by the facile condensation of arylaldehydes with aryloxyamines affording a bisarylaldoxime ether library. Of the library's 95 compounds, 31 were active inhibitors of TTR amyloid formation in vitro. The bisaryloxime ethers selectively stabilize the native tetrameric state of TTR over the dissociative transition state under amyloidogenic conditions, leading to an increase in the dissociation activation barrier. Several bisaryloxime ethers bind selectively to TTR in human blood plasma over the plethora of other plasma proteins, a necessary attribute for efficacy in vivo. While bisarylaldoxime ethers are susceptible to degradation by N-O bond cleavage, this process is slowed by their binding to TTR. Furthermore, the degradation rate of many of the bisarylaldoxime ethers is slow relative to the half-life of plasma TTR. The bisaryloxime ether library provides valuable structure-activity relationship insight for the development of structurally analogous inhibitors with superior stability profiles, should that prove necessary.

  the activation of aromatic aldehydes has been developed. Utilizing thioxanthen-9-one as the photocatalyst and cheap household lamps as the light source, a variety of aromatic aldehydes have been activated and subsequently converted in a one-pot reaction into amides, hydroxamic acids and esters in good to high yields. The applicability of this method was highlighted in the synthesis of Moclobemide, a

  The present disclosure relates to bifunctional compounds, which find utility to degrade and (inhibit) Androgen Receptor. In particular, the present disclosure is directed to compounds, which contain on one end a cereblon ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds Androgen Receptor, such that Androgen Receptor is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of Androgen Receptor. The present disclosure exhibits a broad range of pharmacological activities associated with compounds according to the present disclosure, consistent with the degradation/inhibition of Androgen Receptor.
