  Development of fluorescent peptide substrates and assays for the key autophagy-initiating cysteine protease enzyme, ATG4B

  摘要：

  An efficient assay for monitoring the activity of the key autophagy-initiating enzyme ATG4B based on a small peptide substrate has been developed. A number of putative small fluorogenic peptide substrates were prepared and evaluated and optimized compounds showed reasonable rates of cleavage but required high enzyme concentrations which limited their value. A modified peptide substrate incorporating a less sterically demanding self-immolative element was designed and synthesized and was shown to have enhanced properties useful for evaluating inhibitors of ATG4B. Substrate cleavage was readily monitored and was linear for up to 4 h but enzyme concentrations of about ten-fold higher were required compared to assays using protein substrate LC3 or analogs thereof (such as FRET-LC3). Several known inhibitors of ATG4B were evaluated using the small peptide substrate and gave IC50 values 3-7 fold higher than previously obtained values using the FRET-LC3 substrate.

  Provided is a method for preparing a novel benzocoumarin-based two-photon absorbing fluorescent dye, such as a pyridinium-benzocoumarin (Py + BC) derivative compound and its precursor compound (pyridyl-benzocoumarin, PyBC), an aryl-benzocoumarin (ArBC) derivative compound, a benzothiazolyl-benzocoumarin (BtBC) derivative compound or a keto-benzocoumarin (KetoBC) derivative compound. The Py + BC derivative compound of the present invention is a two-photon absorbing near-infrared fluorescent dye, which may minimize interference of autofluorescence compared to conventional two-photon absorbing fluorescent dyes such as acedan and naphthalimide, thereby obtaining a high-definition image, and therefore is expected to be effectively used in imaging studies. In addition, when the two-photon absorbing near-infrared fluorescent dye of the present invention is used, it is expected to be suitable for high resolution imaging of deep tissue.

  提供了一种制备新型苯并香豆素基双光子吸收荧光染料的方法，例如吡啶铵苯并香豆素（Py+BC）衍生物化合物及其前体化合物（吡啶基苯并香豆素，PyBC），芳基苯并香豆素（ArBC）衍生物化合物，苯并噻唑基苯并香豆素（BtBC）衍生物化合物或酮基苯并香豆素（KetoBC）衍生物化合物。本发明的Py+BC衍生物化合物是一种双光子吸收近红外荧光染料，与传统的双光子吸收荧光染料（如acedan和naphthalimide）相比，可以最小化自体荧光的干扰，从而获得高清晰度图像，因此预计可在成像研究中有效使用。此外，当使用本发明的双光子吸收近红外荧光染料时，预计适用于深层组织的高分辨率成像。

  In immunoglobulin light chain amyloidosis (AL), the unique antibody light chain (LC) protein that is secreted by monoclonal plasma cells in each patient misfolds and/or aggregates, a process leading to organ degeneration. For treating AL patients, such as those with substantial cardiac involvement who have difficulty tolerating existing chemotherapy regimens, provided herein are small molecule compounds of Formula Ia, Formula Ib, and Formula II that are kinetic stabilizers of the native dimeric structure of full-length LCs, which compounds can slow or stop the amyloidogenicity cascade at its origin.
