Synthesis and SAR Studies of Dual AKT/NF-κB Inhibitors Against Melanoma
摘要:
The protein Kinase B alpha (AKT) and nuclear factor kappa‐light‐chain‐enhancer of activated B cells (NF‐κB) pathways are central regulators of cellular signaling events at the basis of tumor development and progression. Both pathways are often up‐regulated in different tumor types including melanoma. We recently reported the identification of compound 1 (BI‐69A11) as inhibitor of the AKT and the NF‐κB pathways. Here, we describe SAR studies that led to novel fluorinated derivatives with increased cellular potency, reflected in efficient inhibition of AKT and IKKs. Selected compounds demonstrated effective toxicity on melanoma, breast, and prostate cell lines. Finally, a representative derivative showed promising efficacy in an in vivo melanoma xenograft model.

Abstract A new one-potprotocol has been developed for the facile and efficient synthesis of aza-fused polycyclic quinolines (e.g., pyrrolo[1,2-a]quinolines) by the base-catalyzed reaction of 2-formylpyrroles and 2-halophenylacetonitriles. This reaction proceeded under transitionmetal-free conditions and showed high functional group tolerance, with the desired products being formed in good yields
摘要 通过2-甲酰基吡咯和2-卤代苯基乙腈的碱催化反应,已开发出一种新的一锅法,用于简便有效地合成氮杂稠合的多环喹啉(例如吡咯并[1,2- a ]喹啉)。该反应在无过渡金属的条件下进行,并显示出高的官能团耐受性,并以良好的收率形成了所需的产物。 通过2-甲酰基吡咯和2-卤代苯基乙腈的碱催化反应,已开发出一种新的一锅法,用于简便有效地合成氮杂稠合的多环喹啉(例如吡咯并[1,2- a ]喹啉)。该反应在无过渡金属的条件下进行,并显示出高的官能团耐受性,并以良好的收率形成了所需的产物。
