  日期：2019.12

  We describe a series of potent and highly selective small-molecule MALT1 inhibitors, optimized from a High-Throughput Screening hit. Advanced analogues such as compound 40 show high potency (IC50: 0.01 µM) in a biochemical assay measuring MALT1 enzymatic activity, as well as in cellular assays: Jurkat T cell activation (0.05 µM) and IL6/10 secretion (IC50: 0.10/0.06 µM) in the TMD8 B-cell lymphoma

  我们描述了一系列有效且高度选择性的小分子MALT1抑制剂，这些抑制剂是通过高通量筛选获得最佳效果的。先进的类似物，例如化合物40，在测量MALT1酶促活性的生化分析以及细胞分析中均显示出高效力（IC 50：0.01 µM）：Jurkat T细胞活化（0.05 µM）和IL6 / 10分泌（IC 50：0.10） /0.06 µM）。化合物40还抑制了MALT1底物RelB的裂解（IC 50：0.10 µM）。机械酶学结果表明，这些化合物与蛋白酶的已知变构位点结合。
