DB2313 is a potent transcription factor PU.1 inhibitor with an IC50 of 14nM[1]. DB2313 disrupts the interaction of PU.1 with target gene promoters[2]. PU.1, a critical transcription factor in the hematopoietic system, plays key roles in myeloid and lymphoid cell differentiation, maintenance of hematopoietic stem cell functions, and the development of acute myeloid leukemia (AML)[3]. DB2313 is usually used in research related to AML and inflammation[4].
In vitro, DB2313 (10μg/ml; 72h) significantly inhibited the proliferation, migration, and invasion of GBM cells (U118MG and U87MG)[5].
In vivo, DB2313 (17mg/kg; every 2 days via intraperitoneal injection for 12 days) significantly suppressed tumor growth and enhanced the recruitment of CD4+ T helper 1 (Th1) and cytotoxic T/natural killer (NK) cells into tumors in the B16-OVA melanoma mouse model[6]. DB2313 (8mg/kg; intranasal administration; 5 days/week for 3 weeks) decreased airway mucus-secreting cell numbers and small airway collagen deposition, and significantly reduced airway hyperresponsiveness in a house dust mite (HDM)-induced experimental asthma mouse model[7].

| Cell experiment [1]: | |
Cell lines | glioma cell lines U87MG and U118MG |
Preparation Method | The glioma cell lines U87MG and U118MG were cultured in DMEM containing 10% fetal bovine serum and 1% penicillin-streptomycin. All cells were maintained in a humidified incubator with 5% CO2 at 37℃. The cells were routinely tested for mycoplasma contamination. 2000 GBM cells were seeded in 96-well plates and measured cell viability using CCK-8 assay at 0, 24, 48, and 72h. GBM cells were treated with DMSO or DB2313 (10mg/mL). EdU assays were performed using an EdU assay kit with GBM cells seeded in well plates at 2×105 cells per well. 2×104 GBM cells were used for the Transwell assay. A total of 2×105 GBM cells were cultured in spheroid formation ECM for 72h to generate tumor spheroids and used for the 3D tumor spheroid invasion assay with a 96-well 3D spheroid BME cell invasion assay kit. Images were taken at 0, 24, 48, and 72h using microscope. |
Reaction Conditions | 10μg/ml; 72h |
Applications | DB2313 significantly inhibited the proliferation, migration, and invasion of GBM cells (U118MG and U87MG). |
| Animal experiment [2]: | |
Animal models | Female wild-type BALB/c mice |
Preparation Method | Female wild-type BALB/c mice were housed under specific pathogen-free conditions and maintained on a 12-hour day-night cycle with water and regular chow available ad libitum. Mice were treated intranasally with house dust mite (HDM; Dermatophagoides pteronyssinus) extract (25µg in 30µL PBS or saline (vehicle), 5 days per week for 3 weeks. One group of HDM-treated mice were treated with DB2313 (8mg/kg in PBS). Bronchoalveolar lavage fluid was collected. Mucus-secreting cells (MSCs) were stained and counted. Collagen was stained and analyzed. Airway hyperresponsiveness was assessed using the forced oscillation technique. |
Dosage form | 8mg/kg; intranasal administration; 5 days/week for 3 weeks |
Applications | DB2313 decreased airway mucus-secreting cell numbers and small airway collagen deposition, and significantly reduced airway hyperresponsiveness in a house dust mite (HDM)-induced experimental asthma mouse model. |
