  2. (+)-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.
  3. 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.

Scientific information:  
Scientific info: (+)-JQ1 is a BET bromodomain inhibitor, with IC50 of 77 nM/33 nM for BRD4(1/2). IC50 Value: 77 nM(for BRD4(1)), 33 nM( for BRD4(2)) Target: BRD4 in vitro: (+)-JQ1 enantiomer binds directly into the Kac binding site of BET bromodomains. (+)-JQ1 (500 nM) binds BRD4 competitively with chromatin resulting in differentiation and growth arrest of NMC cells. (+)-JQ1 (500 nM) attenuates rapid proliferation of NMC 797 and Per403 cell lines as demonstrated by reduced Ki67 staining. (+)-JQ1 (500 nM) potently decreases expression of both BRD4 target genes in NMC 797 cells. (+)-JQ1 inhibits cellular viability with IC50 of 4 nM in NMC 11060 cells. (+)-JQ1 results in robust inhibition of MYC expression in MM cell lines. (+)-JQ1 inhibits proliferating of KMS-34 and LR5 with IC50 of 68 nM and 98 nM, respectively. (+)-JQ1 (500 nM)-treated MM.1S cells results in a pronounced decrease in the proportion of cells in S-phase, with a concomitant increase in cells arrested in G0/G1. (+)-JQ1 (500 nM) results in pronounced cellular senescence by beta-galactosidase staining. (+)-JQ1 (800 nM) exposure leads to a significant reduction in cell viability among the majority of CD138+ patient-derived MM samples tested. (+)-JQ1 inhibits growth of LP-1 cells with GI50 of 98 nM. (+)-JQ1 (625 nM) results in an increase in the percentage of LP-1 cells in G0/G1. (+)-JQ1 (500 nM) suppresses the expression of MYC, BRD4 and CDK9 in LP-1 cells. in vivo: (+)-JQ1 (50 mg/kg) inhibits tumors growth in mice with NMC 797 xenografts. (+)-JQ1 (50 mg/kg) results in effacement of NUT nuclear speckles in mice with NMC 797 xenografts, consistent with competitive binding to nuclear chromatin. (+)-JQ1 (50 mg/kg) induces strong (grade 31) keratin expression in NMC 797 xenografts. (+)-JQ1 (50 mg/kg) promotes differentiation, tumor regression and prolonged survival in mice models of NMC xenografts. (+)-JQ1 (50 mg/kg) results in a significant prolongation in overall survival of SCID-beige mice orthotopically xenografted after intravenous injection with MM.1S-luc+ cells compared to vehicle-treated animals. (+)-JQ1 (50 mg/kg i.p.) leads to a highly significant increase in survival of mice bearing Raji xenografts.
