Phosphotungstic acid (PTA) was rapidly and efficiently anchored on the surface of silica coated cobalt ferrite core to obtain a new three-component CoFe2O4@SiO2-PTA nanocomposite. The resultant composite was characterized by various techniques, including FT-IR, XRD, SEM, EDX, ICP-AES, and VSM. The as-synthesized nanocomposite was examined as catalyst for N-formylation of various amines under solvent-free conditions at room temperature. Due to the presence of magnetic core in this catalyst, it can be easily separated from the reaction media by applying an external magnetic field. The isolated catalyst can be reused for at least five successive times without significant leaching or loss of its high catalytic activity.

Bromodomain-containing Protein 4 (BRD4), an ‘epigenetic reader’, regulates chromatin structure and gene expression via recognizing and binding acetylated lysine in histones. BRD4 has become a therapeutic target for cancers because it promotes the expression of the tumor genes, such as c-Myc, NF-κB, and Bcl-2. In this study, a new series of 3-methyl-1H-indazole derivatives were designed via virtual screening and structure-based optimization. All compounds were synthesized and evaluated for their inhibitory activities to BRD4-BD1 and their antiproliferative effects in cancer cell lines. Among them, several compounds (such as 9d, 9u and 9w) exhibited strong BRD4-BD1 affinities and inhibition activities, and potently suppressed MV4;11 cancer cell line proliferation. Among them, compound 9d showed excellent selectivity for BRD4 and effectively suppressed c-Myc, the downstream protein of BRD4. This study provided new lead compounds for further biological evaluation on BRD4.
