  Exploitation of the Ability of γ-Tocopherol to Facilitate Membrane Co-localization of Akt and PHLPP1 to Develop PHLPP1-Targeted Akt Inhibitors

  摘要：

  Previously, we reported that Akt inactivation by gamma-tocopherol (2) in PTEN-negative prostate cancer cells resulted from its unique ability to facilitate membrane co-localization of Akt and PHLPP1 (PH domain leucine-rich repeat protein phosphatase isoform 1), a Ser473-specific Akt phosphatase, through pleckstrin homology (PH) domain binding. This finding provided a basis for exploiting 2 to develop a novel class of PHLPP1-targeted Akt inhibitors. Here, we used 3 (gamma-VE5), a side chain-truncated 2 derivative, as a scaffold for lead optimization. The proof-of-concept of this structural optimization was obtained by 20, which exhibited higher antitumor efficacy than 3 in PTEN-negative cancer cells through PHLPP1-facilitated Akt inactivation. Like 3, 20 preferentially recognized the PH domains of Akt and PHLPP1, as its binding affinities for other PH domains, including those of ILK and PDK1, were an order-of-magnitude lower. Moreover, 20 was orally active in suppressing xenograft tumor growth in nude mice, which underlines the translational potential of this new class of Akt inhibitor in PTEN-deficient cancers.

  Anticancer compounds according to formula I are described herein. wherein R 1 , R 2 , R 3 and R 4 are selected from H, CH 3 , OH, SH, OCH 3 , NHR′, halogen, CF 3 , N-linked pyrrolidine, and SO 2 NHR′, or any combination thereof; R 5 is an alkyl, alkenyl, or alkaryl group including from 4 to 11 carbons, X is selected from CH 2 , CHOH, C═O, S═O, O═S═O, and an oxetane ring, Y is selected from CH 2 , O, and NH, and R′ is a H, aryl, or a lower alkyl group, or pharmaceutically acceptable salts thereof. The compounds have been shown to facilitate site-specific dephosphorylation of Akt at Ser-473, thereby inactivating Akt and decreasing dysregulation of Akt signaling that can occur in cancer cells.

  根据公式 I，这里描述的抗癌化合物。其中 R1、R2、R3 和 R4 从 H、CH3、OH、SH、OCH3、NHR′、卤素、CF3、N-连接吡咯烷和SO2NHR′ 中选择，或其任意组合；R5 是包括 4 到 11 个碳的烷基、烯基或烷基芳基基团，X 从 CH2、CHOH、C═O、S═O、O═S═O 和氧杂环戒中选择，Y 从 CH2、O 和 NH 中选择，R′ 是 H、芳基或较低烷基基团，或其药用可接受盐。这些化合物已被证明有助于在 Ser-473 处促进 Akt 的位点特异性去磷酸化，从而使 Akt 失活，并减少癌细胞中可能发生的 Akt 信号传导失调。
