| 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. [1] (+)-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. [2] (+)-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. [3] (+)-JQ1 (1 μM) activates HIV transcription in latently infected Jurkat T cells. (+)-JQ1 (50 μM) stimulates predominantly Tat-dependent HIV transcription in both Jurkat and HeLa cells. (+)-JQ1 (5 μM) induces Brd4 dissociation enables Tat to recruit SEC to HIV promoter and induce Pol II CTD phosphorylation and viral transcription in J-Lat A2 cells. JQ1 enables Tat to increase CDK9 T-loop phosphorylation and partially dissociates P-TEFb from 7SK snRNP in Jurkat T cells.[4] | |||||
| 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. [1] (+)-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. [2] (+)-JQ1 (50 mg/kg i.p.) leads to a highly significant increase in survival of mice bearing Raji xenografts. [3] | |||||
| Features | (+)-JQ1 is more effective than (-)-JQ1. | |||||
Protocol(Only for Reference)
Cell Assay:
| Cell lines | MC 11060 cells |
|---|---|
| Concentrations | ~500 nM |
| Incubation Time | 48 hours |
| Method | Cells are seeded into white, 384-well microtiter plates at 500 cells per well in a total volume of 50 μL media. The 797, TT and TE10 cells are grown in DMEM containing 1% penicillin/streptomycin and 10% FBS. The Per403 cells are grown in DMEM containing 1 % penicillin/streptomycin and 20% FBS. Patient-derived NMC 11060 cells are grown in RPMI with 10% FBS and 1% penicillin/streptomycin. (+)-JQ1 is delivered to microtiter assay plates by robotic pin transfer. Following a 48 hours incubation at 37℃, cells are lysed and wells are assessed for total ATP content using a commercial proliferation assay. Replicate measurements are analyzed with respect to dose and estimates of IC50 are calculated by logistic regression (GraphPad Prism). |
