  Helical Twisting Power of New Chiral Dopants Derived from 2–Phenylpropanoic Acid for Nematic Liquid Crystals

  摘要：

  New chiral dopants for nematic liquid crystals were synthesized using optically active 2-phenylpropanoic acid. The magnitude of helical twisting power (HTP) was largely influenced by the linkages between the asymmetric frame and the core moieties. The results of our experiments clearly showed that a steric effect was important to induce a helical macrostructure.

  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.

  interface between the two variable domains of the LC homodimer. We hypothesized that extending the stabilizers beyond this initially characterized binding site would improve affinity. Here, using protease sensitivity assays, we identified stabilizers that can be divided into four substructures. Some stabilizers exhibit nanomolar EC50 values, a 3000-fold enhancement over the screening hits. Crystal structures
