B细胞淋巴瘤6(BCL6)是在淋巴细胞中表达并调节淋巴细胞分化和增殖的转录因子。因此,BCL6是自身免疫性疾病和癌症治疗的治疗靶标。本报告介绍了通过使用生物物理学驱动的基于片段的方法发现的BCL6-corepressor相互作用抑制剂。使用基于表面等离振子共振(SPR)的片段筛选,我们成功地鉴定了片段1(SPR K D = 1200μM,配体效率(LE)= 0.28),它是天然配体BCoR肽的竞争性结合剂。此外,我们将1精制为更有效的化合物7(SPR K D= 0.078μM,LE = 0.37,无细胞蛋白质-蛋白质相互作用(PPI)IC 50 = 0.48μM(ELISA),细胞PPI IC 50 = 8.6μM(M2H))高通量筛选命中。

Through chemical modification and X-ray crystallography we identified the 2,4-bis anilino pyrimidines as potent inhibitors of CDK4. Herein, we describe the optimisation of this series.

The present invention relates to methods for the characterization of enzymes or of enzyme-compound complexes, wherein the enzyme is obtained from a protein preparation with the help of at least one broad spectrum ligand immobilized on a solid support and wherein the enzyme is characterized by mass spectrometry. These methods are useful for the screening of non-immobilized compound libraries, selectivity profiling of lead compounds and mechanism of action studies in living cells.

Disclosed herein are compounds and methods for reducing the risk of developing, preventing, or treating graft versus host disease (GVHD) in a subject. The compounds can concurrently block Aurora kinase A and JAK2 signal transduction which synergistically suppresses alloreactive human T-cells in vitro, prevents xenogeneic graft- versus-host disease without impairing anti-tumor responses, and promotes the development and suppressive potency of CD39+ inducible Treg. In certain aspects, disclosed are compounds of Formula I-V.

The invention encompasses compounds having formula I and the compositions and methods using these compounds in the treatment of conditions in which modulation of the JAK pathway or inhibition of JAK kinases, particularly JAK3, are therapeutically useful.
c-Jun N-Terminal Kinase 1 (JNK1), a key component of the MAPK pathway, has been implicated in the pathogenesis of IPF and represents a potential therapeutic target. However, the development of JNK1 inhibitors has been slowed, partly due to synthetic complexity in medicinal chemistry modification. Here, we report a synthesis-accessibility-oriented strategy for designing JNK1 inhibitors based on computational
