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

In immunoglobulinlightchain (LC) amyloidosis, the misfolding, or misfolding and misassembly of LC a protein or fragments thereof resulting from aberrant endoproteolysis, causes organ damage to patients. A smallmolecule “kineticstabilizer” drug could slow or stop these processes and improve prognosis. We previously identified coumarin-based kineticstabilizers of LCs that can be divided into four
在免疫球蛋白轻链 (LC) 淀粉样变性中,由异常内切蛋白水解引起的 LC 蛋白质或其片段的错误折叠或错误折叠和错误组装会对患者造成器官损伤。一种小分子“动力学稳定剂”药物可以减缓或停止这些过程并改善预后。我们之前确定了基于香豆素的 LC 动力学稳定剂,可分为四个部分,包括“连接器模块”和“远端子结构”。我们之前的研究侧重于表征氨基甲酸酯、乙内酰脲和螺环脲接头模块,它们结合在 V L -V L的溶剂暴露位点LC 二聚体的域界面。在这里,我们报告了基于 7-二乙氨基香豆素的动力学稳定剂的构效关系数据。该子结构占据了先前表征的“锚腔”和“芳香狭缝”。评估了终止于连接在该香豆素环 3 位的各种远端亚结构的酰胺和尿素接头模块的效力。令人惊讶的是,基于 7-二乙氨基香豆素的动力学稳定剂的晶体学数据表明,连接在 3 位的尿素接头模块和远端亚结构结合了全长 LC 二聚体的溶剂暴露区域,这与之前表征的位点不同。我们的结果进一步阐述了

Polymer compositions for coating of metal surfaces including moieties that interact with a metal atom in the metal surface and optionally containing antifoulant moieties. These polymer compositions provide lubricious coatings for medical devices, anticorrosion coatings for metal components, and antifoulant coatings for marine components such as propellers. The polymer composition is synthesized in a safe manner in which the synthesis components are added to a synthesis vat and there is no need for filtration or removal of waste materials in any step including the consumer use. As such this invention provides an environmentally sound approach to composition synthesis, formulation development, and consumer use.
