  Benzazepinones and Benzoxazepinones as Antagonists of Inhibitor of Apoptosis Proteins (IAPs) Selective for the Second Baculovirus IAP Repeat (BIR2) Domain

  摘要：

  XIAP is a key regulator of apoptosis, and its overexpression in cancer cells may contribute to their survival. The antiapoptotic function of XIAP derives from its BIR domains, which bind to and inhibit pro-apoptotic caspases. Most known IAP inhibitors are selective for the BIR3 domain and bind to cIAP1 and cIAP2 as well as XIAP. Pathways activated upon cIAP binding contribute to the function of these compounds. Inhibitors selective for XIAP should exert pro-apoptotic effects through competition with the terminal caspases. This paper details our synthetic explorations of a novel XIAP BIR2-selective benzazepinone screening hit with a focus on increasing BIR2 potency and overcoming high in vivo clearance. These efforts led to the discovery of benzoxazepinone 40, a potent BIR2-selective inhibitor with good in vivo pharmacokinetic properties which potentiates apoptotic signaling in a manner mechanistically distinct from that of known pan-IAP inhibitors.

• Preparation of Phosphoamino Acid Derivatives with Acid Stable<i>O</i>-Phosphono-Protection for the Boc-Mode Solid-Phase Synthesis of Phosphopeptides

  日期：1995.9

  Boc-phosphoamino acid derivatives with O-[di(4-nitrobenzyl)- or dicyclohexylphosphono]-protection were prepared for application to the Boc-mode solid-phase synthesis of phosphopeptides. These protecting groups are both stable to TFA, but removable with a combination of trifluoromethanesulfonic acid and methylthiobenzene in TFA. Of these derivatives, Nα-Boc-O-(dicyclohexylphosphono)serine and Nα-Boc-O-(dicyclohexylphosphono)threonine were obtained as crystalline compounds to be favorably utilized as starting materials for solid-phase synthesis using an automated peptide synthesizer. On the other hand, Nα-Boc-O-(dicyclohexylphosphono)tyrosine and all of the O-[di(4-nitrobenzyl)]phosphono derivatives were prepared as crystalline cyclohexylammonium or dicyclohexylammonium salts.

  制备了具有 O-[二（4-硝基苄基）- 或二环己基膦酰]保护的 Boc-膦酰基氨基酸衍生物，并将其应用于 Boc 模式固相合成磷酸肽。这些保护基团对反式脂肪酸都很稳定，但在反式脂肪酸中与三氟甲磺酸和甲硫基苯的组合作用下可以去除。在这些衍生物中，Nα-Boc-O-(二环己基膦酰基)丝氨酸和 Nα-Boc-O-(二环己基膦酰基)苏氨酸是结晶化合物，可用作使用自动多肽合成器进行固相合成的起始材料。另一方面，Nα-Boc-O-(二环己基膦酰基)酪氨酸和所有 O-[二(4-硝基苄基)]膦酰基衍生物都制备成结晶环己基铵盐或二环己基铵盐。
