  Design, Synthesis, and Characterization of 3-(Benzylidene)indolin-2-one Derivatives as Ligands for α-Synuclein Fibrils

  摘要：

  A series of 3-(benzylidine)indolin-2-one derivatives were synthesized and evaluated for their in vitro binding to alpha synuclein (alpha-syn), beta amyloid (A beta), and tau fibrils. Compounds with a single double bond in the 3-position had only a modest affinity for alpha-syn and no selectivity for alpha-syn versus A beta or tau fibrils. Homologation to the corresponding diene analogues yielded a mixture of Z,E and E,E isomers; substitution of the indoline nitrogen with an N-benzyl group resulted in increased binding to alpha-syn and reasonable selectivity for alpha-syn versus and tau. Introduction of a para-nitro group into the benzene ring of the diene enabled separation of the Z,E and E,E isomers and led to the identification of the Z,E configuration as the more active regioisomer. The data described here provide key structural information in the design of probes which bind preferentially to alpha-syn versus A beta or tau fibrils.

  The description relates to Inhibitors of Apoptosis Proteins (IAPs) binding compounds, including bifunctional compounds comprising the same, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present invention. In particular, the description provides compounds, which contain on one end a ligand which binds to the IAP E3 ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. Compounds can be synthesized that exhibit a broad range of pharmacological activities consistent with the degradation/inhibition of targeted polypeptides of nearly any type.
