Biological Activity for (+)-JQ1
(+)-JQ1 is a potent, high affinity, selective BET bromodomain inhibitor (IC50 values are 17.7, 32.6, 76.9 and 12942 nM for BRD2 (N-terminal (N)), BRD4 (C-terminal (C)), BRD4 (N) and CREBBP respectively; Kd values are 49, 59.5, 82, 90.1, 128 and 190 nM for BRD4 (N), BRD3 (N), BRD3 (C), BRD4 (C), BRD2 (N) and BRDT (N) respectively). (+)-JQ1 induces squamous differentiation in NUT midline carcinoma (NMC) cell lines and inhibits tumor growth in NMC xenograft models in vivo. (+)-JQ1 inhibits proliferation and induces autophagy in bladder cancer cells in vitro and in vivo. It also suppresses MYC gene expression and inhibits proliferation of lymphoma and leukemia cell lines. In human pulmonary microvasular endothelial cells (HPMEC), NF-κB activation, IL-6 and IL-8 expression and proliferation are inhibited by (+)-JQ1. The compound also inhibits transcription of ACE2 and TMPRSS2 genes in mouse lung tissue and prevents infection by SARS-CoV-2. In germ cells from male mice, (+)-JQ1 exhibits reversible contraceptive effects. (+)-JQ1 inhibits the BRD4-JUN-CCL2-TNF-α axis in pancreatic cancer cells and improves survival by reducing macrophage recruitment.
Inactive Analog also available.
Carboxylic acid-functionalized (Cat. No. 6588) and click-activated (alkyne) (Cat. No. 6589) versions for PROTAC development also available.

Epigenetics in Cancer Poster
Adapted from the 2015 Cancer Product Guide Edition 3, this poster summarizes the main epigenetic targets in cancer. The dysregulation of epigenetic modifications has been shown to result in oncogenesis and cancer progression. Unlike genetic mutations, epigenetic alterations are considered to be reversible and thus make promising therapeutic targets.
Rheumatoid Arthritis Poster
Rheumatoid arthritis (RA) is a chronic destructive inflammatory autoimmune disease that results from a breakdown in immune tolerance, for reasons that are as yet unknown. This poster summarizes the pathology of RA and the inflammatory processes involved, as well as describing some of the epigenetic modifications associated with the disease and the potential for targeting these changes in the discovery of new treatments.
