I-BRD9 Chemical Properties,Usage,Production

Description

I-BRD9 is a selective cellular chemical probe for bromodomain-containing protein 9 (BRD9). I-BRD9 has a pIC50 value of 7.3 for BRD9 inhibitor, with greater than 700-fold selectivity over the BET family and 200-fold over the highly homologous bromodomain-containing protein 7 (BRD7). I-BRD9 is also shows a greater than 70-fold selectivity against a panel of 34 bromodomains. I-BRD9 downregulates CLEC1, DUSP6, FES and SAMSN1 genes in Kasumi-1 cells.

Uses

I-BRD9 is a bromodomain-containing protein 9 (BRD9) inhibitor which belong to class of (BET) inhibitors that have shown potent anti-inflammatory and anticancer properties.

Biological Activity

pic50: 7.3i-brd9 is a brd9 inhibitor.brd9 is identified as a bromodomain containing protein forming a small sub-branch of the bromodomain family tree. human brd9 has a single bromodomain and contains five isoforms which are produced by alternative splicing.

in vitro

in previous study, the i-brd9 development was driven by iterative medicinal chemistry, using structure based design to result in nanomolar potency at brd9, over 700-fold selectivity against the bet family as well as more than 70-fold to a panel of 34 bromodomains. in kasumi-1 cells, i-brd9 could downregulate dusp6, clec1, samsn1 and fes genes. moreover, i-brd9 was used to expore genes regulated by brd9 in kasumi-1 cells involved in immune response and oncology pathways. in addition, when brd4 was used as a representative member of the bet family for initial selectivity screening, i-brd9 was found to have a pic50 of 5.3 against this protein. i-brd9 thus represented the first available selective tool compound to investigate the cellular phenotype of the inhibition of brd9 bromodomain [1].
