(-)-JQ-1 is the (R)-Enantiomer of JQ1 or the stereoisomer of (+)-JQ1. While (+)-JQ1 has an IC50 of 77 nM and 33 nM for BRD4(1/2) in enzymatic assays, it is a potent and extremely specific BET (Bromodomain and extra terminal domain) bromodomain inhibitor. No bromodomains interact significantly with ()-JQ1. Additionally, the ()-JQ1 enantiomer is relatively inactive in nuclear protein in testis (NUT) midline carcinoma (NMC). In that it only binds to bromodomains from the BET family and not any other bromodomains, (+)-JQ1 has high specificity for BET. (+)-JQ1 may have anti-cancer properties against a number of cancers, including Multiple Myeloma (MM), Pancreatic Ductal Adenocarcinoma, and Ovarian Cancer. It functions by inhibiting c-MYC and increasing p21. In order to learn more about the function of BET bromodomains in the transcriptional control of oncogenesis, (+)-JQ1 was used as a chemical probe.

(+)-JQ1 enantiomer binds directly into the Kac binding site of BET bromodomains. By competitively binding BRD4 with chromatin at a concentration of (+)-JQ1 (500 nM), NMC cells' differentiation and growth are arrested. By reducing Ki67 staining, (+)-JQ1 (500 nM) inhibits the NMC 797 and Per403 cell lines' rapid proliferation. In NMC 797 cells, (+)-JQ1 (500 nM) significantly reduces the expression of both BRD4 target genes. In NMC 11060 cells, (+)-JQ1 inhibits cellular viability with an IC50 value of 4 nM. [1] In MM cell lines, (+)-JQ1 strongly inhibits MYC expression. KMS-34 and LR5 proliferation are both inhibited by (+)-JQ1 with IC50 values of 68 nM and 98 nM, respectively. (+)-JQ1 (500 nM)-treated MM.A significant reduction in the percentage of cells in the S-phase is caused by 1S cells, and cells arrested in G0/G1 are consequently more numerous. Using beta-galactosidase staining, (+)-JQ1 (500 nM) causes noticeable cellular senescence. The majority of the CD138+ patient-derived MM samples examined exhibit a significant reduction in cell viability following exposure to (+)-JQ1 (800 nM).[2] A GI50 of 98 nM for (+)-JQ1's ability to inhibit LP-1 cell growth. A greater proportion of LP-1 cells are in G0/G1 after treatment with (+)-JQ1 (625 nM). MYC, BRD4, and CDK9 expression in LP-1 cells is suppressed by (+)-JQ1 (500 nM).[3] In latently infected Jurkat T cells, (+)-JQ1 (1 μM) activates HIV transcription. Both Jurkat and HeLa cells are stimulated by (+)-JQ1 (50 μM) primarily Tat-dependent HIV transcription. In J-Lat A2 cells, (+)-JQ1 (5 μM) induces Brd4 dissociation, which allows Tat to attract SEC to the HIV promoter and trigger Pol II CTD phosphorylation and viral transcription. In Jurkat T cells, JQ1 partially separates P-TEFb from 7SK snRNP and enables Tat to increase CDK9 T-loop phosphorylation. [4]

| ln Vivo |
In mice with NMC 797 xenografts, (+)-JQ1 (50 mg/kg) prevents tumor growth. In mice with NMC 797 xenografts, (+)-JQ1 (50 mg/kg) causes effacement of NUT nuclear speckles, which is consistent with competitive binding to nuclear chromatin. Strong (grade 31) keratin expression is induced in NMC 797 xenografts by (+)-JQ1 (50 mg/kg). In mice models of NMC xenografts, (+)-JQ1 (50 mg/kg) encourages differentiation, tumor regression, and increased survival. [1] When SCID-beige mice are orthotopically xenografted with MM.1S-luc+ cells via intravenous injection, (+)-JQ1 (50 mg/kg) significantly increases overall survival compared to vehicle-treated animals. [2] Mice carrying Raji xenografts experience a highly significant increase in survival when given (+)-JQ1 (50 mg/kg i.p.). [3]

| Cell Assay |
Cells are seeded into white, 384-well microtiter plates at 500 cells per well in a total volume of 50 μL media. The DMEM containing 1% penicillin/streptomycin and 10% FBS is used to cultivate the 797, TT, and TE10 cells. Per403 cells are raised in DMEM containing 20% FBS and 1% penicillin/streptomycin. NMC 11060 cells from patients are expanded in RPMI containing 10% FBS and 1% penicillin/streptomycin. Robotic pin transfer is used to deliver (+)-JQ1 to microtiter assay plates. Cells are lysed and wells are examined for total ATP content using a commercial proliferation assay after 48 hours of incubation at 37°C. Replicate measurements are examined in relation to dose, and estimates of the IC50 are computed using logistic regression (GraphPad Prism).
