Histone methyltransferases are involved in various biological functions, and these methylation regulating enzymes' abnormal expression or activity has been noted in several human cancers. Within this context, SET domain-containing (lysine methyltransferase) 7 (SET7, also called KMT7, SETD7, SET9) is of increasing significance due to its diverse roles in(More)
Menin functions as an oncogenic cofactor of mixed lineage leukaemia (MLL) fusion proteins in leukaemogenesis. The menin-MLL interface is a potential therapeutic target in acute leukaemia cases. In this study, approximately 900 clinical compounds were evaluated and ranked using pharmacophore-based virtual screening, the top 29 hits were further evaluated by(More)
Protein arginine methylation is a common post-translational modification which is crucial for a variety of biological processes. Dysregulation of protein arginine methyltransferases (PRMTs) activity has been implicated in cancer and other serious diseases. Thus, small molecule inhibitors against PRMT have great potential for therapeutic development. Herein,(More)
Bromodomain-containing protein 4 (BRD4) is implicated in the pathogenesis of a number of different cancers, inflammatory diseases and heart failure. Much effort has been dedicated toward discovering novel scaffold BRD4 inhibitors (BRD4is) with different selectivity profiles and potential antiresistance properties. Structure-based drug design (SBDD) and(More)
As an epigenetic reader, BRD4 regulates the transcription of important downstream genes that are essential for the survival of tumor cells. Small molecular inhibitors targeting the first bromodomain of BRD4 (BRD4-BD1) have showed promising potentials in the therapies of BRD4-related cancers. Through AlphaScreen-based high-throughput screening assay, a novel(More)
Overexpression of coactivator associated arginine methyltransferase 1 (CARM1), a protein arginine N-methyltransferase (PRMT) family enzyme, is associated with various diseases including cancers. Consequently, the development of small-molecule inhibitors targeting PRMTs has significant value for both research and therapeutic purposes. In this study, together(More)
Protein arginine methyltransferases (PRMTs) catalyze the posttranslational methylation of arginine, which is important in a range of biological processes, including epigenetic regulation, signal transduction, and cancer progression. Although previous studies of PRMT1 mutants suggest that the dimerization arm and the N-terminal region of PRMT1 are important(More)
